How to Check if a USB-C Cable Supports Fast Charging

Fast charging is a relatively recent addition to smartphones that has become common. Some devices can be charged from 0-100 in less than an hour. It’s pretty awesome, but it doesn’t work with just any old USB-C cable.
A typical USB port sends around 2.5W of power to the connected device. Fast charging bumps this up to 15W on the low end, while some go all the way up to 100W. If you want to take advantage of these faster charging speeds, you’ll need to make sure you have compatible accessories.
