iPhone SE comes with Apple’s iPhone SE slow 5-watt charger. However, the phone supports 2.1 amp fast-charging that quickly charges its battery from zero to half in less than 30 minutes. Here are some of the ways to quickly charge the iPhone SE at its fastest supported charging speed –
Fast-charge iPhone SE with 2.4 amp power adapter
iPhone SE can be fast-charged at its maximum possible speed by any 2.4 amp output wall charger. We recommend Anker Powerport 2 Elite 2.4 amp dual USB port charger for the SE because of its 2.4 amp + 2.4 amp dual-port fast-charging ability and stellar solid build and elegant folding design. The charger will top-up the SE from empty to 0% in about 30 minutes which is almost 20 minutes less than the stock Apple SE charger.
A dual port charger is also a better choice over a single port charger as it will allow you to charge two phones (or one phone and a power bank) at once. With the Anker Powerport 2 ‘s dual 2.4 amp output can simultaneously charge your iPhone SE along with another iPhone or an iPad or a power bank at the fast 2.4 amp speeds.
A dual port charger will enable you to charge both your iPhone and your iPad simultaneously at fastest possible speeds as all the iPads also support 2.4 amp fast charging.
Also, almost all good power banks such as the Anker PowerCore 20100 or Anker PowerCore Lite 10000 support 2.4 amp USB charging. The charger will charge the power banks in half (!!) the time taken by the iPhone charger. For example, PowerCore Lite 10000 will take almost 12-14 hours or more to get charged by the iPhone stock charger whereas it will take just 7 hours by the Anker PowerPort 2 Elite dual port charger.
iPhone SE can also get fast-charged by the Apple 12 watt/2.4 amp charger that comes with Apple’s iPads.
Charge iPhone SE fast with a QuickCharge 3.0/2.0 charger or power bank
Many Android phones such as all Samsung and LG/Moto phones these days ship with Quickcharge 3.0/2.0 compatible wall chargers. These chargers will also charge the iPhone SE (as well as other iPhones) at their fastest possible charging speed at about ~2.1 amp @ 5 volts. If you own a QuickCharge 3.0/2.0 phone chargers such as Samsung/LG/Moto phone chargers, then you can charge the iPhone SE at a much fast rate using it than with the iPhone SE stock charger. Most of the latest Android phone chargers such all Samsung smartphone chargers (S10/S9/S8/S7) and LG G8, G7, V40, V30, chargers etc. can fast-charge the SE as they support QuickCharge 2.0/3.0.
Charge iPhone SE faster with a PD+ 2.4 amp adapter (Future-Proof Solution)
USB-C PD has emerged as the fast-charging technology of choice for all latest/upcoming iPhones and iPads. Latest iPhones including iPhone 11, 11 Pro, 11 Pro Max, XR, XS, X, 8, 8+ etc. all support USB-C PD charging which charges these phones from zero to 50% in 30 minutes. A dual port or multi-port 18-watt USB-C PD charger with a 2.4 amp USB output is a future-ready charging solution for SE. This will ensure that when you upgrade your phone in the future, your charger will fast-charge your future iPhone/iPads at their fastest charging speeds.
Any USB-C PD charger such as the Anker Powerport PD 2 can charge your latest iPhone at a fast rate from empty to 50% in about 30 minutes using a USB-C to Lightning cable. For example, Anker Powerport PD 2 will simultaneously fast charge your iPhone SE and another latest iPhone such as 11, 11 Pro, XR, 11, XS, 8, 8+ etc.
Fast-charge iPhone SE with Portable Chargers
2.4 amp portable chargers (without Quickcharge or USB-C PD) usually cost much lower than Quickcharge/PD portable chargers. These chargers are still equivalent to a 2.4 wall charger when it comes to fast-charging the iPhone SE and are hence an excellent cost-effective solution. Our two most preferred 2.4 amp power banks are RAVPower 10K Ultra-Slim and ZMI PowerPack 10K as they have SE fast-charging capability, robust design and come at a decent price. Of the two, ZMI PowerPack 10K is better as it even comes with Quickcharge 2.0 support and can be charged via both new USB-C chargers or the older micro-USB chargers. ZMI is a brand of Xiaomi – the world’s 3rd largest phone maker after Apple and Samsung.
QuickCharge 3.0/2.0 portable chargers can also fast-charge iPhone SE at 2.4 amp speed. Power banks such as ZMI PowerPack 10K, RAVPower 10000 QC 3.0 or Anker PowerCore Slim 10000 support QC3.0/2.0 and can be used to fast-charge the iPhone SE. Such power banks will also fast-charge most latest Samsung/Android phones.
The 2.4 or 2.1 amp fast-charging current required by the iPhone SE can also be delivered by PD portable chargers via their regular USB port. If you own a PD compatible phone such as iPhone 11, XR, XS, etc. or Samsung S10, S9, etc., USB-C PD power banks such as Anker PowerCore 10000 PD or Aukey 10000 PD can fast-charge your SE along with your other PD compatible phone.
As prices of PD power banks have fallen steeply in last one year, we highly recommend that you get a USB-C PD power bank for your iPhone SE as a future-proof purchase. We recommend RAVPower 10000 PD, ZMI 10K Powerpack USB-C, and Aukey 10000 PD as all these have offer excellent quality and can be charged with the micro-USB cables just like all other power banks. Aukey 10000 PD can even be charged directly with the Apple SE charger as it also has Lightning input.
iPhone Fast-Charge: What It Does and Does Not Do
An important point to remember is that the iPhones support fast-charging only till the battery level reaches 80%. The charging current drops down to 1 amp once the battery gets 80% charged, and after that, the charging speed for the remainder of the battery (from 80% to 100%) is same whether you use a 1 amp charger or 2 amp charger. This means that fast-charging is supported by iPhones only when the battery is at a very low level. For example, if you start charging from zero, the iPhone SE will get charged from level zero to 50% in about 60 minutes by the standard iPhone charger but will charged in just about 30 minutes from a 2.4 amp charger. This is almost 50% less charging time. However, if you start charging from 80%, the charging time will be same whether you use a 1 amp charger or 2.4 amp charger.
Also, the battery size of the iPhone is an important factor in determining the time that a 2.4 amp charger will take to charge the iPhone. The bigger the battery size, the more time you will save with a 2.4 amp charger in comparison to a 1 amp charger. For example, iPhone SE will get fully charged (zero to 100%) from a 2.4 amp charger in about 1 hour less than the stock Apple 1 amp charger.
