iPhone 8 Plus has a battery capacity of 2675 mAh – more than any iPhone before it. The 8+ and the 8 are also the first iPhones to be fast-charge capable, meaning it can be charged from zero to 55% in just 30 minutes by an 18-watt or more USB-C fast-charging adapter using a USB-C to Lightning cable. Though, Apple shipped the iPhone 8+ with very slow Apple 5-watt adapter. The best portable chargers for iPhone 8 Plus can fast-charge it super-fast via USB-C PD. Here is our pick of the best fast-charging power banks for the 8 Plus.
Best Premium Slim Fast-charging Power Bank for iPhone 8 Plus
Anker PowerCore Slim 10000 USB-C PD 18-watt
(also has a 20-watt version )
Anker offers some of the best power banks for iPhones. PowerCore Slim 10000 PD is its newest lightweight and premium 18-watt USB-C portable charger with a weight of just 6.8 oz (192 grams) and dimensions of 5.8 x 2.8 x .55 inches (14 x 7 x 1.5 cm). PowerCore Slim 10000 PD will fast charge the iPhone 8 Plus from zero to 55% in about 30 minutes.
The 10000 mAh battery capacity of the portable charger will fully charge iPhone 8 Plus more than two times.
18-watt USB-C PD charging feature of the power bank will also charge other latest iPhones including the latest iPhone 13 & 12 series, 11, 11 Pro/Max, 8, X, XR, XS, and XS Max with a USB-C to Lightning cable. It will also fast-charge most latest Android phones (Samsung S/Note, all Pixels etc.) from zero to 50% in about 30-40 minutes. It also supports 2.4 amp (12 watt) charging which enables the power bank to fast charge the older iPhones (6, 6s, 7, 7 Plus) from empty to 50% in about 40 minutes. It will charge older Android phones to the same level in 50-55 minutes.
Any 18-watt or more USB-C PD fast-charger such as Macbook charger or iPad Pro 2021/2020/18 chargers will fully charge the portable charger in about 4 hours. It can also be charged with standard Apple iPhone 8 Plus charger using an USB-A to USB-C cable in 12 hours.
Please Note: You will require a USB-C to Lightning cable to fast-charge your iPhone 8+ using this power bank. With normal Lightning cable, you will get 12-watt speed. Also, to fast-charge the power bank in 4 hours, a USB-C PD fast-charger is required. As iPhones no longer come with a power adapter, a USB-C adapter is a good investment as it will also charge your 8+ at 3 times the speed of Apple 8+ adapter (5-watt).
PowerCore Slim 10000 18-watt USB-C PD has two charging ports – a USB-C port and a regular USB port, which allow it to charge two phones simultaneously, though at low speeds. It will fast charge the iPhone 8 Plus or iPhone 13/12/11/XR through the USB-C port or fast-charge any older iPhone 6, 6s, 7, 7 Plus, etc. through the other port at its fastest supported charging speed.
Please Note: Anker now also offers a 20-watt version of the PowerCore Slim 10000 18-watt. We recommend 20-watt version as Apple iPhones from iPhone 12 onwards and iPads etc from 2021 onwards support slightly faster 20-watt charging. 18-watt version will also work fine with latest iPhones/iPads as well.)
