No device left behind with four charging ports. Charge your phone with one USB-C port and still have room to charge 3 more devices using the additional 1x USB-C and 2x USB-A charging ports.
Both USB-C outputs are capable of 45W fast charging, this means less time charging and more time doing. You can use either USB-C port to charge your USB-C laptop as well as fast charge other devices including, iPhone, iPad, Pixel and Nintendo Switch.
Bit of a misleading marketing blurb. It's 45W max total output.
