Anker Power Banks: Things To Know Before Buying

Anker is one of the best and most popular brands among power banks. However, a lot of confusion exists in the market about correct product timeline and differences in the features of multiple generations of Anker PowerCore II/PowerCore+/PowerCore/Astro  power banks as well as the correct prices and official sellers on sites such as Amazon.

For example, Anker offers five different models of PowerCore powerbanks in 10000 mAH capacity and another five types of different PowerCore models in 20000 mAH capacity!! All of these are branded PowerCore II or PowerCore+ or PowerCore and look similar to each other but come with varying features and at different price-points. Often, customers end up buying old versions of Anker external battery packs at same price as new and better Anker battery packs . Also, many shady sellers on Amazon exploit this confusion to sell old versions of Anker products at high prices.

Best portable charger
New PowerCore II 6700 is tiny but can fully charge an iPhone 7 twice. It looks better, is scratch resistant and gets charged in just 3 hours
Portable phone battery charger
Astro E1 6700 is the older version and takes 5.5 hrs to charge. It has a side button instead of the more convenient clickable round button of PowerCore II

Here are three things to keep in mind before buying Anker battery packs –

PowerCore+ vs PowerCore II vs PowerCore vs Astro Difference

PowerCore II 20000 review
Anker Powercore II 20000 supports fastest charging for latest Android phones such as S9, S8, S7 and gets charged in just 5 hrs compared to 12 hrs taken by old PowerCore 20100.
Anker PowerCore II vs PowerCore+
Anker PowerCore 20100 is the older 20000 mAh capacity power bank and does not have many features such as fast charging and fast input charging of the powerbank.




The PowerCore II series and PowerCore+ series are the latest Anker series of power banks at present. However, many PowerCore series powerbanks (without the +) and much older Astro series of powerbanks are also currently  available in same battery capacities as their Powercore+ or PowerCore II equivalents. We have created a handy table for your reference below – that is better than the product tables at Amazon’s product pages – to help you make an informed decision.

A more recent version of power bank will not only have better charging and device and battery  protection technology but also often offer many additional features. For example,  the latest Anker PowerCore II 20000 not only supports fast charging compatible with maximum charging speeds of latest smartphones such as Galaxy S8, S8+, Pixel II etc. but also supports fast input, which means that the powerbank itself gets charged in just 5 hours compared to 12+ hrs taken by by older PowerCore 20100 and Astro E6 battery bank with the same 20000 mAH capacity.

Buy From AnkerDirect – The Only Official Anker Seller

An extremely important thing to remember is that AnkerDirect is the only seller authorized for selling Anker power banks on Amazon. A lot of scammer sellers sell Anker portable power packs on Amazon with various misleading names. Many of these fake sellers sell old Anker power banks at higher rates while some sell refurbished or even fake Anker power banks. Buying power banks from such fake sellers will not only cost you higher but will also not allow you to benefit from Anker’s generous 18-month warranty and reliable customer service. There are also very serious accident risks involved with buying fake power banks that use cheap Li ion batteries.

Here at, we give you direct links to buy authorized genuine Anker battery banks that ensure that you get genuine powerbanks at lowest prices and full warranty.

Prefer the Latest PowerCore II/PowerCore+ Versions

Anker has so far released two generations of Astro power banks, followed by multiple versions of PowerCore power banks, again followed by the Powercore+ series as well as the latest PowerCore II series. As old Astro series and PowerCore series products were not discontinued, this has created a lot of confusion in the market. The existence of all five series of products at once is also sometimes used by some scammers to sell very old (but well-known) versions of Anker power banks and that too at higher prices.

Anker is continually releasing new versions of PowerCore powerbanks with some cool new features that even older PowerCore or PowerCore+ does not have! For example, the latest PowerCore II 10000 and the latest PowerCore II 20000  both offer features such as fast charging (50% in 30 minutes) support for Samsung S9, S8, S7, five-hour charging of the powerbank and 3 amp charging for latest USB-C phones at almost the same or lower price as older versions. Similarly, the latest versions also  come with better special charging chipsets that prevent heating while charging, thereby increasing efficiency and safety.

For example, the latest PowerCore II 10000 Slim powerbank offers BOTH QuickCharge 2.0 compatible Input and Output and is 33% slimmer and narrower than old versions, thus making it much more pocketable. It is priced almost same as plain vanilla older PowerCore 10000!

The latest PowerCore II 20000 offers 18 watt maximum charging charging output per port (old PowerCore 20100 had 12 watt), QuickCharge 2.0 fast charging support compatible with all latest Samsung smartphones including S9, S9+, S8, S7, Note 8 etc. (old PowerCore lacked this) and fast input charging for charging the powerbank in just 5 hours compared to the 12 hours + taken by the old Anker PowerCore 20100.

Newly released PowerCore Speed 20000 PD can charge iPhone 8, 8+, and Iphone X to 50% in just 30 minutes

Similarly, the newly released and less-known Powercore Speed 20000 PD will charge your iPhone X, 8+ or 8 to 50% in just 30 minutes and can be recharged in just 4 hours. It also supports fastest charging for Samsung Galaxy S9, S9+, S8, S7, Note 8 as well.

If you own iPhones 7, 7 Plus, 6S etc. that do not require QuickCharge, you can choose the much lesser priced excellent Anker PowerCore 20100, which will charge your iPhone 7/6S. etc at fastest possible speeds. It will also charge Android phones at 12 watt maximum charging output, which is slower than USB-C PD or QuickCharge’s 18 watt but still very fast than standard USB’s 5 to 2.5 watt.

Here are the latest Anker PowerCore, PowerCore+, and PowerCore II External Battery Packs according to battery capacity. We have also included the shopping links for the only authorized Anker seller on Amazon – AnkerDirect.

57 thoughts on “Anker Power Banks: Things To Know Before Buying

  1. Hi, great site, very helpful info. I have a few questions:

    I only have apple products (iPhone 5, 6s, and 2 iPad’s), I wouldn’t benefit from QualComm Quick Charging (ASIN: B00VLNT9KW) when charging my devices, correct?

    I could however benefit in that the Anker itself would charge up faster if connected to a Qualcomm fast charging brick, correct?

    But none of the apple devices’ power bricks nor the devices themselves would benefit from QC2.0 nor QC3.0, correct?

    1. Hi Richard,
      Yes, You are correct! Apple products (as of now) will not benefit from Quickcharge 2 or 3 in Anker 200000 with QC 3.0.

      Also as the powerbank you mentioned (Anker 200000 with QC 3.0, ASIN: B00VLNT9KW) is Quickcharge output only , you will not benefit from the powerbank charging quickly as the powerbank will get charged in the normal time only.

      We suggest you opt for the older and lower-cost Anker Powercore 20000 (without QC 3.0) if you do not plan to buy any non-Apple products in near future. It will also charge your iPhone at twice the standard charging speed and the iPad to its maximum possible charging speed at 2.1 Amp.

      Apple-supplied iPhone chargers only charge at 1 Amp and hence the high-amp output will cut charging times for iPhones by about half.

      We also suggest using (or buying if you do not have one) a 2.1 Amp+ wall charger such as the RAVPower 24 W 2.4 Amp dual USB charger for charging the powerbank at it maximum possible rate – about 10 hours for a full recharge.

  2. Where I can find authorized seller of anker power bank in the country of QATAR, I see lots of anker power bank sell in Qatar but I don’t know if its genuine or fake ANKER power bank, and to determine a genuine and fake ANKER power banks

    1. Hi Melvin,
      In Qatar, you can buy genuine Anker products from

      To avoid purchasing fake/counterfeit products, it is best to avoid small shops for buying such products and better to go with large chains such as Souq.


  3. Interesting site.

    Looking to power a Garmin Edge 1000 gps unit during a long (18-hour-non-stop) bicycle ride – any advice as to features / capacity I should be looking for?


    1. Hi Peter,

      Thanks! The good news is that Garmin GPS 1000 is not a very power hungry device (compared to smartphones), and hence a low-cost good 10000 mAH powerbank should be more than adequate to power it for 18-hours of screen time. If you ONLY plan to power the Garmin 1000 and not your phone you can skip the QuickCharge powerbanks. However, we recommend to go with a minimum 10000 mAH powerbank with Quickcharge and with 2 ports so that you can charge your phone (if required) and Garmin 1000 at the same time. Another important factor for outdoor use is that it is recomended that your powerbank is waterproof and shock/dust proof Our recommended powerbank with all the above features is RAVPower 10050mAh Outdoor Portable Charger . It is priced well, has two ports, and is rugged enough for outdoor/biking use.

      Happy Biking! 🙂

    1. Hi Maria, If you have purchased from Amazon, then make sure that you have purchased from AnkerDirect the only authorized Anker product seller on Amazon. Other than Amazon, in the US, the only other major authorized online sellers for Anker powerbanks are Staples, Newegg, and RadioShack. To be on the safe side, it is better to purchase only from these sellers.
      One way to know if your product is genuine is to call Anker support at +1 (800) 988 7973 (in US) or at +44 (0) 1604 936 200 (in UK) and enquire about the warranty by giving your order no or other proof of purchase to the customer care representative.

  4. Hi,

    Very helpful web page. For a Samsung S7 edge, is this not compatible with quick charge 3.0? What would you recommend?

    Many thanks,


    1. Just found out that quick charge 3.0 isn’t compatible with my samsung; would you recommend getting the quick charge 2.0 or still the 3.0 as it’s backwards compatible?

      1. Hi Mary,

        Thanks for the query. We recommend choosing a QC 3.0 Input/Output powerbank as – as u said – it will be backward compatible with QC 2.0. The difference in price between QC 2.0 and 3.0 powerbanks is not large while there is a big leap in charging performance and it will serve you well in future if/when you upgrade your phone. Also, an extremely useful benefit is that if you choose a powerbank that has both QC 3.0 Input & Output, your power bank itself will get charged blazingly fast with QC 3.0 even though it will charge your galaxy edge with QC 2.0! 🙂

        Some such recommeded powerbanks with QC 3.0 Input/Output are: Anker PowerCore+ 10050 QC3.0, Anker PowerCore+ 26800 QC 3.0 and RAVPower 20100 QC 3.0/USB-C. The RAVpower 20100 QC3/USB-C is our favorite pick as it also comes with USB-C input/output charging making it very versatile for charging future smartphones and even laptops/ultrabooks.


  5. What is the best way to charge a power bank? I’ve had my 10050 on the basic phone wall charger for 5 hours and it hasn’t moved.

    1. Hi Billy,

      First recharges for most powerbanks can be very frustrating as they take extremely long on basic .5 to 1 amp phone wall chargers. For first charge of a 10050 mAH powerbank on a basic .5 amp wall charger, make sure u pressed on button on the powerbank after connecting….and wait 20-24 hours! Slowly, slowly, one after other the blinking lights will progress with full charge in a maximum of 24 hours. If there is still no progress after 24 hours of non-stop charging, you should consider raising a replacement/return request.

      10000 mAH is 10 Ampere-hours so at the rate of .5 amperes per hour from the basic charger it will take about 20 hrs to charge in theory. After factoring in conversion efficiency of about 90%, it is more like about 24 hours in practice.

      For 20000 mah and more, just double/multiply the time accordingly (48-72hrs!).

      Do not worry, as all subsequent/later charges will take far lesser time even when using the same wall charger.

      Looong charging times for high-capacity powerbanks are one big reason to go for quicker charging USB-C input or Quickcharge 3.0 input powerbanks and USB-C/QC 3.0 wall chargers.

      Thanks and do let us know the progress! 🙂

  6. My old E1 has packed up, so looking to replace with an equivalent, I use it mainly to run my Mobius camera from a bike bar bag. It has worked excellently for quite a few years.

    Should I just get a direct E1 replacement or the 2nd Gen or the new powercore slim 5000 both of which are around £5 dearer?

    Or any other alternatives?

    Thanks for your advice.

    1. Hi Steve,

      We recommend getting an Anker PowerCore Slim 5000. The advantage of Powercore slim over E1 is that Powercore Slim will get recharged in less than half the time (3.5 hrs) taken by E1 using a 2.4 amp wall charger such as Anker 12W USB wall charger Wall Charger.

      Another good news is that at present there is a promo going on at Amazon UK that will offer you 50% discount on the 2.4 amp Anker 12 W USB wall charger if you combine it with PowerCore Slim!! To get it, go to the Anker Powercore Slim page on Amazon UK first and also order the wall charger from the displayed promo link 🙂

      Tip: To prolong life of your powerbank, please charge and discharge it at least once every 3-4 months.


      1. Thank you for your quick reply, I was kinda tempted with the 5000 slim as the bar bag is tall and long.

        However, you have thrown a spanner in the works with a review for the powercore 10000. With slightly different dimensions would this represent better value for money @ £20?

        Thanks again for your input.


        1. Hi Steve,

          Thanks for the feedback. PowerCore 10000 indeed offers more bang per buck than 5000 Slim. However – with the exact same budget – our favorite recommendation right now on Amazon UK is Anker PowerCore 15600 that delivers 55% extra battery capacity than Powercore 10000 in a quite compact package!! 🙂

          Happy shopping!

  7. Thanks for this article! great help!
    Just wondering if you could explain what the mAH units mean and what the implication means for me as an end user of choosing one of a lower/higher value?
    And what does input/output only mean?

    1. Hi Jay,
      Thanks for the positive feedback.

      Mah is a measure of battery capacity. To put it simply, the more the MaH value, the longer will your powerbank last. So a 10,000 mAH powerbank will fully charge a smartphone with ~2000 mAH battery iPhone 7 about 3.5 times while a 20,000 powerbank will charge it around 7 times.

      Input only means that the charging technology or standard mentioned (like Quickcharge) is only for charging the powerbank and NOT for charging devices using the powerbank. Output only means that the charging technology mentioned is used only while charging the devices from the powerbank but NOT when you are charging the powerbank itself using quickcharger.

      Our recommendation is to of course go for both Input/Output powerbanks. However, QuickCharge or USB-C Output only powerbanks are a good low-cost option if you intend to just charge your devices quickly and do not mind slow (7-14 hrs) charging times for the powerbanks. A very good example is Anker PowerCore 20000 with QC 3.0 output only which offers huge capacity and superfast charging for your smartphones at a bargain price.

      We do not exactly recommend input only powerbanks as you will always find a nice Output only or Input/output powerbank for every budget.


      1. Thank you for the clear and concise explanation.
        I’m considering getting the Anker PowerCore 20100 as that looks like it offers high-speed input and output charging with a relatively substantial mAh. I’m sure it’ll suffice for my Samsung Galaxy S5 + one or two older models which my parents have that we hope to charge while out on holiday in the middle of nowhere.

        Just wondering if you recommend stepping up the purchase to the Anker PowerCore+ 20100 USB-C for an extra £10 (~$14 USD) more? From what I understand USB-C will only benefit the very latest phone models and others in the future. So would it be worth future-proofing myself? And is the prime advantage of USB-C a faster device charge rate?

        And while not intended for it, I take it given the ubquity of the mini-USB to USB port charging offered by such power banks, I can then use the cables to charge other devices such as my digital cameras or other devices.

        1. Hi Jay,
          Thanks for the response and queries. Yes, we will definitely recommend going for a USB-C powerbank at present to futureproof any powerbank purchase as USB-C is fast becoming the standard for Android due to support for it by Google.

          USB-C does not always provide faster charging time over other rapid charging standards – it mostly depends on the particular charging voltage/current supported by the device. But for most upcoming devices (such as Galaxy S8), it will generally offer equivalent or faster charging times. Other big advantages of USB-C is its versatility (you can charge smartphones, most latest and upcoming laptops including Macbooks, and even other devices such as Nintendo switch) and two way charging connectivity (your phone can act as powerbank for other devices).

          While shopping for USB-C powerbanks, we recommend choosing a powerbank with highest total wattage output in your budget as, in the case of USB-C, higher output wattage implies higher charging speed for supporting devices. For example, both Anker 20100 USB-C and RAVPower 20100 USB-C offer 15 watt output. RAVPower 20100 USB-C PD or RAVPower 20100 USB-C PD offer 30 watt and can charge a Macbook (or a supporting phone or Nintendo Switch) at twice the speed of a 15-watt powerbank. USB-C output wattage can theoretically range up to 100 watts!! (no such USB-C powerbanks or devices exist at present!) and in future this will enable USB-C to charge larger and more powerful appliances and peripherals.

          To summarize, both Anker 20100 USB-C and RAVPower 20100 USB-C are excellent choices. RAVpower 20100 USB-C costs a bit lower than Anker and also comes with support for Quickcharge 3.0, which is useful if you or your family owns many/any Quickcharge 3/2/1 devices Galaxy S5 does not have support Quickcharge).


          1. I have ordered from 28600 mah aestro e7 ultra power is it good to buy from souq in dubai

  8. Where I can find authorized seller of anker power bank in country India, I don’t know if its genuine or fake ANKER power bank, and to determine a genuine and fake ANKER power banks

    1. Hi Rawat,

      Thanks for the query. Buying Anker powerbanks in India can be tricky as many unauthorized sellers sell Anker battery packs at crazy steep prices. At present, in India, we thing the best bet is to purchase Anker products through Cloudtail India – Amazon India’s own seller-subsidiary. Cloudtail also offers the best prices on Amazon India for Anker powerbanks and you can get some very good deals if you explore. For example, these two bestselling Anker powerbanks on Amazon India sold by Cloudtail – Anker PowerCore 10400 White
      & Anker PowerCore 10400 Black


  9. I’m confused about buying Anker external battery. Anker powercore 15600 mAh (for price 200 SAR), Anker powercore with quickcharge 10000 mAh (200 SAR) and Anker powercore+ 13400 mAh (220 SAR). The price for all these 3 models is almost same. Kindly give a detailed comparison. Thanks

  10. Hi,
    Loved this helpful article.
    I’m considering different models of Anker but not sure which one to go for or where to get it from specially that I can no more order it from Amazon US and get it shipped to Bahrain. If you can please help me with your suggestions, I’m looking for one that support fast charging facility and can charge my Samsung Note5 for 2-3 times, need this for outdoor hence light weight is an advantage.
    I’m also not sure where to get it from. I found a shop selling them but the description at the bottom was in Chinese and the prices were very low so I thought they might be fake ones.
    Thanks for your assistance.

  11. Hi,

    I am looking for a recommendation on which Anker PowerBank I should invest in. I am going to be doing a bit of traveling soon, and I will need a portable charger since I will mainly be out and about (rather than near an outlet). The phone that will be used with this powerbank will be an iPhone 7 and iPhone 6. Also, I have a Sony HX80 camera that charges via USB (so I am hoping that an Anker powerbank could work for that). I hope you can help me with choosing a powerbank! Thanks!

    1. Hi Lydia, Thanks for the query. We will recommend a minimum 20000 mAH powerbank for travel and charging 3 devices. As iPhones do not use Quickcharge or USB-C, you can select from less expensive power banks that do not have Quickcharge or USB-C. However, a powerbank with Quickcharge Input (or any other fast charging input) will give you the benefit of quickly recharging the powerbank in about 5-6 hrs whenever you have access to a wall outlet as compared to the 12-13 hrs taken to usually recharge such massive capacity powerbanks.

      Based on your unique use-profile, we highly recommend Anker PowerCore II 20000 and Anker PowerCore 26800 power banks. Anker PowerCore II 20000 offers best value for money while Anker PowerCore 26800 offers the maximum TSA-allowed battery capacity, though at a price premium.

      Both these powerbanks have dual input and will get recharged in under 6 hours via a 2.4 amp capable wall charger. Both these powerbanks have 3 output ports with max 6 amp output, meaning you can charge both your iphones and the camera at their maximum charging speeds simultaneously from the powerbank!

      If you intend to charge all your 3 devices and the dual input powerbank simultaneously using a wall charger, you will require 5 USB ports all capable of 2 amp+ output. For this, we will recommend using heavy duty 4-6 port wall chargers with 50 watt+ capacity such as the RAVPower 60W 12A 6-Port USB Charger or Anker Powerport 6 60w 12A 6-port charger. Both of these will recharge all the 4 devices (2 iPhones, camera, and the dual input powerbank) simulataneously at their maximum possible charging capacity.

      Thanks & happy travels!
      Do let us know if you have any further queries,
      PBG team

  12. Hi,

    I’m looking for an Anker 26800 for my iPhone 6s Pluse and my iPad Pro 12.9″ 2017.

    On Amazon (UK) I find Anker PowerCore+ 26800 PD (AK-A1375011) at 70 UKP , a PowerCore+ with Quick Charge 3 (AK-A1374011) at 90 UKP, and a Power Core (no plus) witgh Dual Input (AK-A1277021) as 120 UKP.

    I understand that the best powerbank for my ipad is the one with PD but, funnily enough, I am worried because it’s the cheapest! (

    What do you suggest?

  13. Can I ask for advice, am planning a 3 week trek. I will need to regularly charge a Usb battery charger for my canon Eos m5 batteries, my Samsung phone, a kindle and a gopro.

    What is the best power bank setup, ideally I want to avoid paying to charge when staying at trekking lodges.

    Shall I go for high capacity? Or low weight, low capacity coupled with an anker solar panel.

    1. Hi James,

      Thanks for the query. A very important factor here is the number days you will be out in the wild at an average without access to a charging outlet. In order to help you find the best battery-mix, let us calculate the approximate daily battery requirement. If we add-up the estimated battery requirements of all your devices, we see that you will require a charge of about 8000-9000 mah per day if you charge all the devices with the following assumed use pattern:

      #Samsung phone (3000 mah battery once a day) -> 3000 mah
      #Go pro Hero 5/6 (about 1200 mah x twice a day -> assuming 3+ hrs of Gopro recording use) -> 2500 mah
      #EOS M5 (about 1000 mah once a day using LP-E12 battery) -> 1000 mah
      #Kindle paperwhite (about 1420 mah full battery will last for about 28 hrs of use or say 1 week of use @4hrs per day) – 200mah

      So we have about 6700 mah of approximate theoretical battery requirement in a day. Taking into account various voltage/conversion losses etc. a realistic rough estimate will be about 9,000 mAH+ a day.

      At this rate of battery consumption, a high capacity 26,800mah powerbank will last you about 3 days. As far as a solar panel is concerned, its charging capacity will depend on how sunny the place is where you will be trekking as well as altitude/latitude/hours facing direct sun/ambient temperature/shade of trees etc. A high-efficiency 21-watt solar pack such as Anker 21 w dual USB will realistically generate about 6000-7000 mAH in 6-7 hrs of direct winter sun in a day assuming you are in lower-US or central/southern Europe. On the trail, it is best to assume that the charging rate will be half of this – about 3000mah a day. Thus a solar charger will enable you to top-up the high-capacity 26800 charger and increase its use to about 4-5 days.

      With these considerations in mind and assuming we want to lug minimum weight, here are our recommendations:

      #1 We recommend a no-frills high capacity 26800mah powerbank with dual-input charging for rapid overnight charging from a wall charger whenever available and fast dual charging from solar panel, should you choose one.
      Two good choices are-
      Anker 26800 Portable charger & RAVpower 26800 USB-C charger
      Both these weigh a pound each.

      #2 It is a good idea to have an additional small backup charger with you – minimum 10,000 mah is fine. Good choices are Anker PowerCore II 10000 (//Pros: 7-oz/200gms weight, QC 2.0 charging for Samsung //Cons: Costs about $13 more than RAVpower, one port only) or RAVpower 10000 (//Pros: Inexpensive, 2 charging ports //Cons: Weighs 2oz/60 gm more, no Quickcharging for Samsung phone) .

      #3 If your budget allows, do buy a solar panel charger for a long trek. In my personal experience, when on the trail, a solar charger gives peace of mind that you will NEVER be completely out of battery and desperate for a wall charger. While buying solar panels, opt for the largest available size (21 watt) for 2 reasons:
      – The difference in prices/size/weight between 15w & 21w is very small (about $10) but you get 40% extra power
      – You are better off capturing as much sun as possible everytime you come out of the shade while walking (or in low winter sun). Bigger solar panels are better for this.

      Happy Exploring!

  14. Hi Rabh, I’m looking for a power bar to charge two Samsung Galaxy mobile phones though not necessarily at the same time. The first one is a Galaxy J3 and the other is a Galaxy S4 mini, what power bank would you recommend? Thanks

    1. Hi Terry,

      As both of these phones support a maximum of 2 amp charging, you need not buy expensive powerbanks with Quickcharge etc.
      The recommended powerbanks for Samsung Galaxy S4 mini and Galaxy J3 are –
      Anker PowerCore 10000 & Anker PowerCore 13000

      Both of these offer excellent value for money with PowerCore 10000 being the smallest powerbank and PowerCore 13000 being the best option if you need a powerbank with 2 ports. If you ever upgrade your phones, both of them will continue charging even the latest phones at pretty fast charging speeds as they are capable of charging at up to 2.4 amps (PowerCore 10000) & 3 amps (PowerCore 13000).


  15. THANK you for this article. I’ve been looking for a comprehensive look at Anker.

    I’m a long distance backpacker and have been using a Dizaul Solar Charger,Dizaul 5000mAh. I’m not happy with the 5000mAh as it seems very inaccurate…and the solar part does little to nothing. I’ve looked far and wide for another similar system that carries 5000-10000mAh with a solar recharge capability…but have found nothing that fits or I trust. This leads me to a reliable battery only option instead.

    I’m looking for something that gives me between 3-6 recharges (I’m out for 2-6 days at a time) and something that is as LIGHT as possible. I have an IPhone 7 and don’t need multiple ports. I only need to charge my phone and will only use 50% of the battery at most daily.

    Is the PowerCore 13000 my best bet at 8.47 oz and very few extras??
    Thanks so very much!

    1. Hi Adam,
      PowerCore 13000 is indeed seems to be the best choice with your specific requirements regarding weight. You can also consider RAVPower 16750 as well as it weighs just 2.2 oz more (10.7 oz) and will give you about 1.5 charges more than PowerCore 13000 (6 full charges of iPhone 7).

      PS. Apologies for the delayed reply due to a bug in our anti-spam plugin blocking a lot of the genuine comments.

  16. Thanks for all the helpful info. I have Samsung A5 2017 and I think I will buy an S7 or S7 Edge in the future …so what do you recommend amongst Anker powerbanks in the 10000 mAh category. Does Anker have a powerbank with USB type c?Thanks!?

    1. Hi Moni,

      For Samsung A5 with future upgrade to S7 or S7 Edge, the best option right now among 10000 mah class Anker powerbanks is Anker PowerCore II 10000.
      PowerCore II supports Quickcharge 2 charging used by Samsung S7/S7 Edge & A5 & you also get the benefit of fast charging of the powerbank charger.

        1. Yes…PowerCore II 10000 & PowerCore II Slim 10000 are the most recommended powerbanks in 10000 mah category even for non-S7/S8 phones. Both offer 5 volt @ 3 amp fast charging, Quickcharge 3.0/2.0 compatible fast charging, & fast charging for the powerbank itself in 4 hours using Quickcharge wall chargers. Both are similar with a maximum charging output of 18 watt with the difference being that PowerCore II 10000 is much lighter and compact and hence costs more.

  17. Good morning

    Sorry for my English. I speak French. Wow, this website is very helpful. I had read everything and spend hours trying to understand how powerbanks work.

    Right now I have a Iphone SE. So I will need a powerbank to charge a cell phone and a compact camera (I might buy the Canon Powershot SX730 HS 20.3 MP). However I will change my cell phone at the end of the year. I still have no idea if I will keep an Apple cell phone or go with a Samsung Galaxy so I need a versatile powerbank that can be great for both Apple and Androids.

    After reading all your comments here (I hope I understood correctly ah ah), I would go for

    20,000 powerbank (I would take the 26800 but it’s too heavy!)
    I will go for both Input/Output powerbanks
    Minimum 2.4A outputs
    Minimum input port that supports at least 2A over 5V.
    Minimum 2 ports

    Which of the 20000 powerbank do you suggest???

    I am confused with USB-C/Qualcomm/Quick charge.

    I understand that Qualcomm’s quick charge is only for some smartphones. Not mine.
    However, do you suggest to take this in case I upgrade for a better Iphone or Galaxy later on?
    Right now it won’t make any difference if I use this with a Iphone SE, right? It won’t harm my device, but it won’t charge any faster?

    Which option should I buy?

    If I understand correctly, most Anker powerbank are not sold with a USB wall charger (apart from the Anker PowerCore+ 26800 that is way too heavy)? Or is there a great 20000 Anker powerbank that is sold with a fast wall charger?

    If not, my wall charger is the Apple cube. I think it’s a 1 amp phone wall charger so I guess it’s not providing sufficient power? That means it will not charge quickly enough, right? So do I need to buy a quicker wall charger? Will it make a BIG difference? I am confused… “A 2.4 amp capable wall charger”, as you wrote? Or shall I wait till I buy a newer cell phone, as I read that “new rapid chargers with technology such as Quick Charge support 2 amps. Older iPhones that support only 1 amp can’t be charged faster at all.” I will save some money..

    Thank you so much in advance for your time! Much appreciated!

    1. Hi,

      Thanks for the query. For current and near future smartphone powerbank requirements, we strongly recommend USB-C PD powerbanks as both latest Android smartphones latest Apple iPhone X, iphone 8/8+ support USB-C PD of about 18 watts.

      The good news is that Anker does have a newly released and less well-known powerbank which satisfies all you current/future requirements and it even ships with a bundled USB-C 30 watt charger. This is the Anker PowerCore Speed 20000 PD with 22.5 watt USB-C PD output. It also comes bundled with a 30 watt USB-C charger and hence you will not have to buy the wall charger separately. It is out recommendation as –
      – It supports the maximum fast charging current of Apple iPhone X, iPhone 8 and 8+
      – It supports maximum charging USB-C PD current of new Android phones
      – It has 2 ports as per your requirements
      – It comes with a bundled USB-C PD wall charger
      – You can charge the Anker PowerCore Speed 20000 PD in just 4 hours with the supplied USB-C wall charger
      – The powerbank/wallcharger combo is extremely good value for money considering the price of similar powerbanks and wall chargers in the market.
      – It will even charge Nintendo Switch (18 watt) at maximum charging speed. Besides this, it can also charge Macbooks at decent speed (22.5 watt).


      1. Thanks a lot Rabh. Very helpful!

        I’ve looked at the price of newer smartphones but it might be a bit too expensive for now, so I will probably go for older versions, such as the Galaxy S7 or the Iphone 6 or 6S (for the next 2 years). Right now I only have an Iphone SE and a camera. I know that this phone do not support QC but after reading the reviews here, you all suggest to buy an option with QuickCharge 3.0 Output and input.

        So I guess I should buy either PowerCore II 20000 or PowerCore Speed 20000 for now?

        What is the big difference between both options?

        Which one do you recommend?

        thanks a lot! 🙂

        1. Hi Murielle,

          The big difference between PowerCore II 20000 or PowerCore Speed 20000 is that PowerCore II 20000 supports maximum input/output of 18 watt (roughly equivalent to Quickcharge 2.0) while Powercore Speed supports input/output of 24 watt (Quickcharge 3.0 compatible with max of 12v @ 2 amp).

          S7/S7 edge do not support QC 3.0 & support a maximum charging current (9v @ 1.67 amp) that is compatible with QC 2.0.

          For S7/S7 Edge or iPhone 6/6S/7, we will recommend PowerCore II 20000 as it costs few bucks less and supports maximum charging speeds for both Samsung Galaxy S7/S7 edge (9v @ 1.67 amps or QuickCharge 2.0) and iPhone 6S (5v @ 2.4 amp). It will also get charged in a decent time (about 8 hrs) using standard S7 wall charger or 2.4 amp USB wall charger. You can combine it with an Anker QC 3.0 dual port charger.

          If you spend few bucks more for PowerCore Speed 20000, you will be able to recharge your powerbank in abt 5.5 hours using the Quickcharge 3.0 wall charger. As you can see, it is not that much of a big difference when charging from empty to 100%. With QC 3.0 of PowerCore Speed, the real difference is that it recharges your depleted powerbank with maximum possible charge (about 30-40% more than PowerCore II) that is currently possible in a rapid short charging session of 15 mins to 1 hr. This may be helpful in situations where you have forgotten to put your powerbank on charge 6-8 hours beforehand. Whether it is worth the $10 CAD extra that Anker is charging for it will depend on your specific use requirements! 🙂

  18. Looking at replacing Monkey solar charger/battery that isn’t working out, useless in wilderness hunting. Looking at Anker 21 watt solar and Anker battery pack that will charge off of it very well. Considering 1oooo/20000/26800 and leaning more towards Power Core II 20000 but like size of Slim power core or Power Core II 10000. Have heard not all external batteries can charge off of solar?? What is best combo??
    Thanks, Marc

    1. Hi Marc, It is true that not all external batteries can handle solar charging well. However, the good news is that both PowerCore II 20000 and PowerCore Slim 10000 work well with Anker 21 watt solar panel. So I guess it comes down to weight as PowerCore Slim 1000 weighs (and costs) much less (9 oz vs 13 oz) than PowerCore II 20000.

      Personally, if I have to choose one I will recommend Anker PowerCore II 20000 due to three reasons –
      – Extra or reserve backup capacity is always handy on the trail. Sunlight supply is often very inconsistent and moreover as solar charging is quite slow, especially when on the move, the reserve battery capacity offered by 20000 mah is always handy when outdoors.
      – Battery wear due to tens of solar charging cycles during the day will be far less on a 20000 mah battery as it is more likely to remain in the golden 25%-75% battery zone most of the time compared to a 10000 mah battery.
      – A partially charged 20000 battery will charge faster than a partially charged 10000 mah battery of same remaining charge whenever sunlight becomes available.

      All of these IMO make Anker PowerCore II 20000 better for solar charging.

  19. Hi,

    This is a very helpful page you’ve got here – however, I am wondering if you might be able to help me?

    I’m looking on Amazon in the UK, at two possible Anker power bank options – the Anker Astro E1 5200mAh, and the Anker PowerCore 5000mAh – aside from one being 5200mAh & the other 5000mAh, I’m struggling to figure out the difference!

    All I need is to have something to keep in my rucksack, which can give me a single charge of my Sony Xperia X Compact – just as a backup.

    Any thoughts or recommendations?


    1. Hi, We recommend PowerCore 5000 mAh as it gets charged in half the time of Astro E1 and is also a much more newer version.

      Another great option, especially for travellers is PowerCore Fusion 5000. It combines wall charger and powerbank in one package, meaning you will have to remember to pack just one item instead of two.


  20. Are you able to advise please? I’m looking to buy a power bank but find all the specs confusing. I need it to charge an iPhone 6s, a 10.5″ iPad pro and a HTC Android phone. I don’t expect to be upgrading any of these any time soon. Would like more than one output as I envisage charging two devices at the same time. Please can you advise which would be best? Go easy – we’re pensioners!

    1. Hi Oska,
      Considering your unique requirements, we recommend:

      Anker PowerCore 20100 – This is our ideal recommended powerbank for you. It has 2 ports and weighs 12.5 oz (about 360gm) and is very well priced as well. It will recharge your ipad pro from 10% to full once and recharge both your phones (iPhone 6S & HTC) from 10% to full twice each.

      We have excluded powerbanks with too much bulk and features such as Quickcharge/USB-C/PD etc. that you will not necessarily need. PowerCore 20100 can charge any of your two devices at excellent speed simultaneously and is a reliable, robust, easy to carry, and well-priced powerbank.

      If the above links do not auto-direct to PowerCore 20100 on Amazon UK, here is the direct Amazon UK link – Anker PowerCore 20100


    1. Hi Monique, We suggest Anker PowerCore 13000 Compact

      Reasons –
      # It will charge iPhone 7s three times at its fastest supported speed. It even charges Androids at almost QC 2.0 speeds
      # It costs hardly 2-3 bucks more than 10000 mAH version
      # It is the lightest 13000 powerbank in market. At just 8.5oz (255 gms) it weighs even less than 10000 mAh powerbanks of other brands.
      # Excellent compact build and reliable customer service

      As an added aside, Anker PowerCore 13000 Compact is also the best compact powerbank for Google Pixel, Pixel XL, Pixel 2, Nexus 5/6, and One Plus 5T, 5, 3, 3T. The reason being its support for 5v @ 3 amp charging. Very few compact powerbanks support 5v/3 amp charging.
