We used the same iPhone X for all tests, plugged into the same outlet. All USB-C charging accessories were paired with a USB-C to Lightning cable from Apple, priced starting at $25. The 5W and 12W chargers from Apple were paired with a standard Lightning cable from Apple, priced starting at $19. 87W USB-C power adapter from Apple (Free with 15-inch MacBook, $79 alone) 30W USB-C power adapter from Anker ($30) 29W USB-C power adapter from Apple (Free with 12-inch MacBook, $49 alone) 18W USB-C power adapter from Choetech ($17.99) Apple's default 12W iPad charger (Free with iPad, $19 alone) 7.5W Belkin Boost Up Wireless Charging Pad from Apple ($59.95) (Tested at 5W and 7.5W) 5W wireless charger from Choetech ($16) Apple's default 5W iPhone charger (Free with iPhone, $19 alone) These tests also apply to the iPhone 8 and 8 Plus, which share many of the same features available in the iPhone X. We tested several charging accessories from both Apple and third-party manufacturers with the iPhone X to see how charging speeds compare across different charging methods. Every method is different - some are faster and more expensive, while others are slower but more convenient. With the addition of both fast charging and wireless charging to Apple's 2017 iPhone lineup, there are more ways than ever to charge your iPhone.
