The Iniu power bank features three output ports: a built-in 45W USB Type-C cable, another 45W USB Type-C port, and a USB Type-A port with up to 18W of power. The 45W Power Delivery is sufficient to charge the Nintendo Switch (18W) and Steam Deck (40W) at their maximum speeds.

It's robust, with a break strength of 44 pounds, and the lanyard loop, when clipped, has a break strength of 13 pounds.
