The power bank is equipped with three output ports: a built-in 45W USB Type-C cable, a 45W USB Type-C port, and a USB Type-A port delivering up to 18W. The 45W Power Delivery ensures that you can charge the Nintendo Switch (18W) and Steam Deck (40W) at their maximum speeds.

The cable is robust, with a break strength of 44 pounds, while the lanyard loop, when clipped, has a break strength of 13 pounds.
