This INIU power bank comes with a robust 20,000mAh, or 74Whr battery capacity. With an 80% power efficiency, you can expect the following approximate full charges for your gaming handhelds:

  • Nintendo Switch (16Whr): about 3.7 times
  • Steam Deck (40Whr): about 1.9 times
  • Apple iPhone 16 (14Whr): about 4.2 times
  • Apple iPhone 16 Plus (18Whr): about 3.3 times

The INIU power bank features three output ports: a built-in 45W USB Type-C cable, a 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 speed. It's also an excellent choice for your Apple iPhone 16, as ChargerLAB tests indicate that the maximum charging rate tops out at around 30W, even for the Pro Max model.

A standout feature of this power bank is the built-in cable, a convenience typically found in more expensive models. This means you no longer need to carry your own USB Type-C cable. When you're out and about, the USB plug can be clipped onto the power bank to create a handy lanyard. The cable is notably durable, with a break strength of 44 pounds, and the lanyard loop, when attached to the power bank, has a break strength of 13 pounds.
