Long charging times is a common complaint of iPhone 7 users as the included 1-amp or 5-watt Apple charger that comes with the iPhone 7 can not charge it at its fastest supported charging speed. The good news us that it is possible to charge iPhone fast at more than twice the speed of the Apple iPhone 7 charger using a 2.4 amp fast charger ( UK-Type Plug version ).
The new iPhone 12 series phones (as well as new iPhone 11/SE 2020 etc.) support 20-watt USB-C PD fast-charging but do not come with any charger in the box. So if you plan to upgrade in near future you can get a future-proof USB-C charger ( UK type Plug version ). This will fast-charge your iPhone 7 at 2x the speed of Apple charger now and fast-charge your future iPhone 12/12 Pro/12 Mini/11/XR/SE 2020 etc. at 20-watts in future (zero to 60% in 30 mins).
Here are some of the ways to fast charge iPhone 7 at speeds of zero to 50% in about 30 minutes.
Charge iPhone 7 fast with a 2.4 amp charger
You can charge the iphone 7 really fast at its maximum supported charging speed by using a 2.4 amp output wall charger. We recommend Anker’s excellent Powerport 2 Elite 2.4 amp dual USB port charger ( UK-Type Plug version ) for charging iPhone 7 from zero to 50% in about 30 minutes (almost twice as fast as Apple iPhone 7 stock charger).
A dual USB port charger is a better option than a single port charger as it costs almost same as a single port charger and allows you to charge two phones (or your power bank and your phone) or your iPad and your iPhone at the same time at fast speeds. All iPads support 2.4 amp charging and a dual 2.4 amp USB charger will allow you to charge your iPhone and iPad at their fastest supported speeds at the same time.
A dual port charger is a great accessory if you have a power bank such as Anker Powercore Lite 10000 or PowerCore 20100. The 2.4 amp charger will charge the power bank in less than half the time taken by the iPhone stock charger. For example, PowerCore 20100 takes almost 20+ hours to charge with iPhone charger but gets charged in about 10 hours with Anker PowerPort 2 Elite dual port charger.
Charge iPhone 7 fastest with a Future Proof USB-C PD + 2.4 amp charger
All the new iPhones (and iPads) released after 2018 (iPhone 12, 11, XR, XS, XS Max, X, 8, 8 Plus) now come with USB PD fast charging support. This means you can charge your iPhone 8/8+/XR/XS/11/12 etc. from zero to 50% in about 30 minutes with a USB-C PD charger such as Anker 32 watt Dual Port ( UK type Plug version ) and a USB-C to Lightning cable.
If you want maximum future proof compatibility, we recommend that you get a dual port or multi-port PD charger with a 2.4 amp capable USB port. One good example is Anker 32 watt Dual Port or Anker Powerport PD 2. This will allow you to charge your existing iPhone 7 fastest and also allow you to charge any new iPhone 12/11/XR/XS/8 etc. or iPad that you may buy at speeds of zero to 50% in 30 minutes.
You can also use a dual port 2.4 amp car charger as well.
Charge iPhone 7 fast with a QuickCharge charger or Power bank
A USB-C PD power bank such as Anker PowerCore 10000 PD or ZMI 10000 PD is the most future-proof portable fast-charging solution for the iPhone 7 as newer iPhone 12/11 etc. support super fast USB-C charging to 60% in 30 mins. As USB-C power banks these days cost same as non USB-C power banks it makes sense to get a USB-C power bank instead of a plain power-bank.
All Quickcharge 3.0/2.0 capable wall chargers used by Samsung/LG Android phones are also capable of delivering the 2 amp current @ 5 volts required by the iPhone 7 for fast charging. This means that you can use any Quickcharge 3.0 charger or Quickcharge 2.0 wall chargers. All recent Samsung phones come with a Quickcharge 2.0 equivalent charger that can also fast-charge the iPhone 7. Similarly, most Android phones these days (LG G8, G7, G6, V40, V30, V20 etc.) come with Quickcharge 3.0/2.0 chargers that can also be used for fast charging the iPhone 7.
If you have a Quickcharge 3.0/2.0 phone such as Samsung S10/S9/S8/S7/Note 9, Note 8, J7, J5 etc. or LG G8/G7/G6 or Moto G7/G6/G5 then you can use your Samsung/LG/Moto phone’s charger to fast charge the iPhone 7. You can also use Quickcharge 3.0 power banks to fast charge iPhone 7.
Charge iPhone 7 fast with a 2.4 amp portable charger or power bank
If you want to charge the iPhone 7 faster even when you are away from a power outlet, the best way is to charge it with a 2.4 amp capable portable charger (power bank). Such power banks will charge the iPhone 7 at same speed as a 2.4 amp power adapter and are the perfect solution to charge it during travel, or commutes.
Two good 2.4 amp capable excellently priced power banks are PowerCore Lite 10000 and PowerCore 20100.
All Quickcharge 3.0/2.0 capable power banks will also charge iPhone 7 at 2.4 amp speeds. If you have a Quickcharge 3.0/2.0 phone such as Samsung S/Note/A series etc. then you can use a Quickcharge 3.0/2.0 power bank such as RAVPower 10000 QC 3.0 or Anker PowerCore Slim 10000 to fast charge both your Samsung phone and the iPhone 7.
Many PD capable power banks also come with a separate USB port that can output 2.4 or 2 amp for the iPhone 7. If you have a PD compatible phone such as iPhone XR/XS/8 or Samsung S10/S9 etc or any Google Pixel, a PD power bank will charge bothyour PD phone and your iPhone 7 at fastest speeds.
Charge iPhone 7 fast with the iPad charger
iPads comes with Apple 10/12 watt stock chargers and these 10/12 watt chargers can also be used to fast-charge your iPhone 7 at its fastest speed. You can also use your iPad Pro 2018/2019’s USB-C PD charger to fast charge the iPhone 7.
iPhone Fast Charge – What it Does and What it Does not Do
iPhone charges fast from zero battery level to till it reaches battery level of 80%. After reaching 80%, the charging current drops significantly below 1 amp and the type of charger (1 amp or 2 amp) does not make a difference. This means that fast charging will best work when your phone is at very-low battery level and above 80% it will not make any difference. For example iPhone 7 will charge from zero to 50 in about 50 minutes with the stock charger but when charged with a 2.4 amp charger it gets charged from zero to 50% in 30 minutes, thus reducing charging time to 50% by 20 minutes.
Also, the bigger the your iPhone’s battery the more difference 2.4 amp charging will make compared to 1 amp charger. For example, the iPhone 7 Plus (2900 mah battery). gets fully charged from zero in 1 hour less by a 2.4 amp charger. The iPhone gets charged fully from empty (0 to 100) in about 30 minutes less (about 1 hour 50 mins) with a 2.4 amp charger compared to a 1 amp charger (about 2 hours 20 minutes).
