Customer Reviews:
I almost didn’t buy this product because of one of the top reviews claimed in didn’t deliver the full advertised 100W. Turns out that it does. | My guess is that either people who claim otherwise have a faulty unit (unlikely). Or, more likely, they are using a USB-C cable that doesn’t support 100W. In order to get the full 100W, you need to use a cable that supports 5A current. That’s a limitation of the USB-C PD spec in general, not of this particular charger. So if you use a high-power device like a 16″ MBP, make sure your cable supports 100W (20V/5A).
