iPhone 7 Plus has a large battery but comes with the slow Apple 5-watt charger. However, the iPhone 7 Plus can be charged more than two times faster and at its fastest supported charging speed of 10-watts, you can charge it from zero to 50% in just about 45 minutes. Here are some of the best ways to fast-charge iPhone 7 Plus two times faster than the Apple charger or about zero to 50% in 45 minutes.
Charge iPhone 7 Plus fast with 2.4 amp power adapter
Our top and future-proof recommendation is to use a dual port (USB + USB-C) charger. The new iPhones such as the iPhone 12 series do not come with a charger in the box byt support super-fast 20-watt charging over USB-C. A dual port adapter such as Anker 32 watt Dual Port will charge your current iPhone 7 Plus at twice speed via the USB port and charge your future iPhone 12/13 at its fastest possible 20-watt speed via the USB-C port – zero to 60% in 30 mins.
A lower cost way is to use a 2.4 amp output wall charger to fast-charge the iPhone 7 Plus at its fastest possible speed of 10-watt. Anker Powerport 2 Elite 2.4 amp dual USB port charger is our recommended choice for 7 Plus because of its 2.4 amp dual port fast-charging ability and durable design. It will charge the 7 Plus from empty to half in about 45 minutes which is about 30-35 minutes faster than the iPhone 7 Plus stock charger.
Though there are many single port 2.4 amp chargers in the market, the dual port chargers are a much more useful option as you can charge two phones or any other two devices at once. For example, you can charge your iPhone 7 Plus along with another iPhone or an iPad or even a power bank at 2.4 amp speed. As all iPads also support 2.4 amp fast charging, a dual port charger will allow you to charge both your iPhone and your iPad simultaneously without any compromise in charging speed.
Also, a dual 2.4 amp USB charger is great if you own a power bank such as the PowerCore Lite 10000 as it will charge the power bank in less than half the time taken by the iPhone charger! For example, PowerCore Slim 10000 takes almost 12 hours to get charged by the iPhone stock charger whereas it gets recharged in under 6 hours by the Anker PowerPort 2 Elite dual port charger.
Future Proof Fast-Charge for iPhone 7 Plus with a USB-C and 2.4 amp adapter

iPhone Fast-Charge: What It Does and Does Not Do
Every iPhone has a tendency to get fast-charged only till 80%. Once the battery level reaches to 80%, the charging current drops down to 1 amp and after that, it will not matter whether you use a 1 amp charger or 2 amp charger. This means, fast-charging is relevant in iPhones only when the battery is at a very low-level. For example, 7 Plus will get charged fast from level zero to 50% in about 80 minutes by the standard iPhone charger and only in about 40 minutes from a 2.4 amp charger . This cuts the charging time to 50% right-away by half by (40 minutes). Once you go above 60% charging time differences will be much lower.
Also, the battery size of the iPhone also matters and determines the time that a 2.4 amp charger will take to charge the iPhone. The bigger the battery size, the moe time you will save with a 2.4 amp charger in comparison to a 1 amp charger. For example, iPhone 7 Plus 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.
