No more guessing games. With a built-in LED digital wattage meter display, the DigiWATT cable from Naztech lets you clearly monitor exactly how much power your device draws while it charges. For the absolute ultimate universal compatibility, this USB-C cable supports Power Delivery charging up to the maximum 240W level - so you can plug in and visibly fast charge any and all USB-C devices, from low-power headphones to high-power laptops, and everything in-between.
