This INIU power bank comes with a robust 20,000mAh, or 74Whr battery capacity. Considering an 80% power efficiency, here's how many full recharges you can expect for each device:

  • 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 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 fastest rates. It's also an excellent choice for charging your Apple iPhone 16, as ChargerLAB has demonstrated that the maximum charging rate tops out at around 30W, even for the Pro Max model.

The built-in cable is a standout feature, typically found on more expensive power banks, eliminating the need to carry an additional USB Type-C cable. When you're on the move, the USB plug can be clipped onto the power bank to create a convenient 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.
