This Iniu power bank is equipped with a 10,000mAh (37Wh) battery. Factoring in approximately 80% power efficiency, here’s how many full charges you can expect for some popular gaming handhelds and smartphones:

Nintendo Switch (16Whr): about 1.9 times Steam Deck (40Whr): about 0.74 times Apple iPhone 16 (14Whr): about 2.1 times Apple iPhone 16 Plus (18Whr): about 1.6 times Nintendo Switch 2 (20Whr): about 1.5 times

*The Apple iPhone 17 is expected to have a slightly larger battery than the iPhone 16.

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. The 45W Power Delivery is sufficient to charge the Nintendo Switch (18W) and Steam Deck (40W) at their top speeds. It's also a good fit for the Apple iPhone 16, as ChargerLAB tests indicate its maximum charging rate peaks around 30W. The iPhone 17 is anticipated to have similar charging capabilities.

The built-in cable is a popular feature on modern power banks, eliminating the need to carry a separate USB Type-C cable. In this model, both ends of the cable are detachable. This design is arguably more versatile than a permanently attached cable, as the cable can be used independently with other devices.
