Now that companies like Apple, Google and Samsung are no longer including power adapters with new phones, getting the right fast charger for your iPhone or Android smartphone, laptop or other device is a little trickier than it used to be. And while it hasn’t happened yet, given the increased focus on reducing e-waste and expanded support for USB Power Delivery (USB-PD), I wouldn’t be surprised if that trend crosses over into the laptop market sometime in the next five years. So to help sort out the confusion, I gathered 14 different chargers from a range of brands and tested each one with five different devices to find out which one is the best fast charger.
How we tested
The methodology for my experiment is intended to be as straightforward as possible. I drained each device to 10 percent battery, plugged in a power brick and then recorded the amount of charge added every 10 minutes for an hour. Each adapter was plugged directly into a standard 120-volt outlet (without the use of a power strip or any extension cords), and when possible I used the cable that either came included with the battery charger or one made by the same manufacturer as the device. If that wasn’t an option, I used certified 100-watt USB-C cables made by Anker, Apple and others.
