• Steam Deck (40Whr) – approximately 1.9 times

The Iniu power bank includes three output ports: one built-in 45W USB Type-C cable, one 45W USB Type-C port, and one USB Type-A port delivering up to 18W. The 45W Power Delivery supports fast charging for the Nintendo Switch (18W) and Steam Deck (40W) at their maximum speeds. It’s also an excellent choice for charging your Apple iPhone 16, as ChargerLAB testing shows that even the Pro Max model caps at around 30W.

The built-in cable is a convenient feature found on many premium power banks, eliminating the need to carry your own USB Type-C cable. The USB plug can be clipped onto the power bank to double as a lanyard. The cable is durable, with a break strength of 44 pounds, while the lanyard loop holds strong with a 13-pound break strength.

The 10,000mAh model is also on sale
