Best Power Banks for Samsung Galaxy S8, S9, Note 8 & Note 9

Samsung Galaxy S9, S8, S7 series as well as Note 9, Note 8, Note 5, and Note 4 phones are currently the bestselling Android smartphones in the world. While these phones come with hefty 3000 mah to 4000 mAh batteries, the ever power hungry apps and games have made portable power backup essential not only for travellers and commuters, but also for general users.

Samsung Galaxy S8, S9, S7, Note 8 and Note 9 — 18 watt Fast Charging Works For All

The best thing while deciding to buy a powerbank for Samsung Galaxy or Note series phones is that all the recent Samsung Galaxy and Note phones use the same fast charging method and hence require exactly the same type of powerbanks. That is right. From the latest Galaxy S9+, S9, S8, S8+, Note 8 to the older S7, S7 Edge, S6, S6 Edge, Note 5, older S5, S4 phones – all of them can be charged at the fastest possible speed (about 50% charge in 35 mins)  with powerbanks that support  18 watt (9 volt @ 2 amp) charging. This means –

  • All the Samsung Galaxy S series, Note series as well as J7, J5, A9, A7, A5, A3 series phones can be charged at fastest speed using USB-C PD powerbanks with minimum output of 18 watt.
  • All these Samsung smartphones can also be charged at fastest speed using any QuickCharge 3.0 or Quickcharge 2.0 supporting powerbanks. This is because the 18 watt (9 volts @ 2 amps) fast charging mode supported by Samsung phones is supported by both QuickCharge 2.0 and Quickcharge 3.0.

Therefore, if you use Samsung Galaxy S series or Note series smartphones, the powerbank you purchase for your existing phone will continue to be of optimum use for fast charging even if you upgrade in the future to other newer Samsung smartphones.

Here is our list of the best fast charging power banks for the latest Samsung smartphones –

Best Lightest and Compact Fast Charging Power Bank for Samsung S9 and S8 (also for Note 9, Note 8, S7, Note 5, A series & J series)

RAVPower 10000 QC 3.0 power bank is just .6 inches thick and has a size similar to S9/S8

The RAVPower 10000mAh QC 3.0 weighs almost same (6.8 oz or 192 gm) as our other favourite compact powerbank – Anker PowerCore II 10000. Both these powerbank support 18 watt fast charging and hence the charging performance of both these portable chargers are also the same. Both RAVPower 10000mAh QC 3.0 and Anker PowerCore II 10000 come with one charging port. Also, you can charge RAVPower 10000mAh QC 3.0   slightly faster (about in 3.5 hrs ) than Anker’s powerbank (4 hrs) by using any good Quickcharge 3.0 wall charger.

Best powerbank for Samsung Galaxy S6
PowerCore II 10000 is extremely compact and light at just 6.9 oz (195 gms)

Anker PowerCore II 10000 is a robustly built compact battery that can handle rough handling due to its squat and solid build.  RAVPower 10000mAh QC 3.0 is slimmer (.6 inches) and more pocketable than Anker PowerCore II 10000 which is .9 inches thick. Due to this you can easily hold  RAVPower 10000mAh QC 3.0   in your hand together with the phone while recharging.

RAVPower 10000mAh QC 3.0 has lifetime warranty (compared to Anker’s 18 months) and costs less than Anker PowerCore II 10000 .

Performance-wise both are equally matched and either Anker PowerCore II 10000  or the RAVPower 10000mAh QC 3.0  will be a great choice if you need the lightest fast charging power backup solution for Samsung S9, S8, S7, Note 8 and all other Series, J series, and A series phones.

Best Slim Fast Charging Power Bank for Samsung S9, S8, Note 9 and Note 8 (as well as A series & J series)

Anker PowerCore II Slim 10000

Anker PowerCore II Slim 10000 is our top choice as fast charging slim powerbank for Samsung S9, S8, Note 9, Note 8 and other Samsung Phones. It will fully charge S9, S8, Note 8 etc. two times.

It has a weight of 7.4 oz (209 gm) and has dimensions of 5.4 x 2.6 x.6 inches. Overall, we found it to be slightly sturdier in build than RAVPower’s slim RAVPower 10000mAh QC 3.0  portable charger. The 6.4 oz RAVPower is a better option if you want a powerbank that is both light and slim.

Pros

  • Slim and phone sized powerbank can be held in hand with the phone while charging
  • Supports fastest charging for all Samsung smartphones including S9, and S9+.

Cons

Best 20000 mah Fast Charging Power Bank for Samsung S9, S8, Note 9 and Note 8 (as well as A series & J series)

Anker PowerCore II 20000 

RAVPower 20100 USB-C

Anker PowerCore II 20000 and RAVPower 20100-C are our picks as fast charging 20000 mah (4 full charges) powerbanks for  Samsung S9, Note 9, Note 8, S8, and S7.

Another strong feature feature of RAVPower 20100-C  is its price. At this price point, there is no other powerbank that can not only charge All Samsung phones but also recharge many other top phones at fastest  speeds.

However, its only drawback is that it weighs 3 oz more than our other pick the Anker PowerCore II 20000.

Best High Capacity Fast Charging Power Bank for Samsung S9 and S8 (as well as Note, A series & J series)

RAVPower 26800 USB-C PD

Anker PowerCore+ 26800 QC 3.0 with wall charger

Anker PowerCore+ 26800 US-C PD bundled with USB-C wall charger

All these three excellent powerbanks come with the highest TSA-allowed battery capacity (27000 mah or 100 Watt-hours) and will fast recharge Samsung S9, S8, Note 8, etc. five times. While all the four are perfectly good portable chargers for your S9/S9+/S8/S7/ or Note 8, we are describing their differences in detail to help you make an informed choice.

RAVPower 26800 USB-C PD 30 watt comes without any bundled wall charger and it can be recharged either by a standard USB 2.4 amp wall charger in 14-15 hours or by a US-C PD wall charger in 4.5 hours. RAVPower 26800 USB-C PD will also recharge your Macbooks, iPad, Nintendo Switch, iPhone X/8/8+, and most other USB-C Android phones at fastest speed.

We recommend buying a USB-C PD 30 watt portable charger such as RAVPower 26800 USB-C PD  (instead of a QC 3.0 powerbank) as both Google and Apple are moving towards USB-C PD in their latest phones. The latest iPhones (iPhone X, 8, 8+) also now support USB-C fast charging.

Please Note: To charge RAVPower 26800 USB-C PD  in 4.5 hours, use a 30-watt+ USB PD wall charger such as RAVPower Super-C USB PD  or Anker Powerport II USB PD wall chargers (and not a 30 watt regular USB-C charger). We recommend Anker Powerport II USB PD  as it will charge both your PD powerbank and your S9/S8/Note 9/Note 8 simultaneously at fastest possible speeds from a single watt outlet.

Anker 26800 PD portable charger review
RAVPower 26800 PD can be charged in two ways – with any standard micro-USB output wall charger or with a USB-C wall charger

Pros

  • Fastest charging for all Samsung smartphones including S9, S9+
  • Can charge a wide variety of phones and devices such as Macbooks, iPads etc at fastest speed.
  • Can be charged via a USB-C wall charger in 5 hours
  • Can also be charged with both a USB-C wall charger or a regular wall charger in about 14 hrs ( using 2 amp wall charger).

Cons

  • An option with bundled USB-C wall charger would have been good

Anker PowerCore+ 26800 QuickCharge 3.0 with wall charger is a great cost-effective high capacity portable charger option for your Samsungs if you also require a QC 3.0 wall charger.

The Anker Powercore+ 26800 will get charged by the bundled QC 3.0 charger in about 7 hours. Using a standard 1 amp USB charger, it will take up to 24 hours to charge.

Anker Powercore+ 26800 will also recharge QC 3.0 smartphones such as Sony XZ1, Nokia 8, LG V30, HTC U11, at highest speed.

Pros

  • Fastest charging for all Samsung smartphones including S9, S9+
  • Can be charged via a QC wall charger in 7 hours

Cons

  • While it is a great choice for fastest charging of all Samsung phones as well as QC 3.0 phones such as Sony XZ1, HTC U11, Nokia 8, etc. the support for QC 3.0 in future devices is uncertain and USB-C PD has the upper hand.
  • Gets charged slower than USB-C PD version (7 hrs vs 4.5 hrs)

Anker PowerCore+ 26800 USB-C PD is Anker’s latest version of its PowerCore+ 26800 high capacity powerbank and comes with 30 watt USB-C PD support.

It is a great choice if you require both a powerbank and a quality USB-C PD wall charger as the bundled USB-C wall charger will cost almost $30 if purchased separately.

The Anker Powercore+ 26800 PD can be charged by the bundled 30-watt USB-C PD wall charger in about 5 hours.

Fast charging USB-C powerbank for S8
Powercore 26800 USB PD has adequate power to fast charge Galaxy S9 more than 5 times

The Anker Powercore+ 26800 PD will also recharge all devices requiring USB-C PD such as Macbooks, USB-C ultrabooks, iPad, Nintendo Switch  (while being played), iPhone X/8/8+, and most other upcoming USB-C Android phones at their fastest speed. We recommend buying a USB-C PD 30 watt portable charger (instead of a Quickcharge 3.0 powerbank) as both Google and Apple are moving towards USB-C PD in their latest phones and the charging speeds of USB-C PD powerbanks are almost same as QC 3.0 powerbanks.

Besides being reasonably future proof, an added advantage of USB-C PD portable chargers is that high capacity USB-C PD portable chargers such as Anker Powercore+ 26800 PD or RAVPower 26800 USB-C PD can be charged much faster over USB-C PD ( about 4.5 hours) than their Quickcharge counterparts (7 hours+).

Pros

  • Fastest charging for all Samsung smartphones ranging from S9, S9+ to S8, S8+, J series and A series
  • Can charge Macbooks, iPads, Nintendo Switch, USB-C ultrabooks et.c at fastest speed.
  • Can be charged via a USB-C wall charger in 4.5 hours

Cons

  • A lower priced option without the bundled USB-C wall charger would have been good for users who already have a wall charger
