The charger does just what it says. Fast charging for supported devices. I wish the plug into the charger was a traditional USB instead of USB c type. If this were the case I wouldn't have to purchase new cables. I don't think I have any devices that can take advantage of the high out put of this charger. But my daily use as a phone/ laptop charger has been a great experience.
I bought this charger to complement the one that I received with my Apple MacBook Pro. It is very nice and the build quality looks good. It also charges as expected. However, the cable itself is hard to plug into the computer. This did not happen with a USB-C cable I purchased through Monoprice nor others from other vendors.
