This INIU power bank comes equipped with a robust 20,000mAh, or 74Whr battery capacity. Considering an 80% power efficiency, here's how many full charges 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: one built-in 45W USB Type-C cable, one 45W USB Type-C port, and one USB Type-A port delivering up to 18W of power. With 45W of Power Delivery, it can charge 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 tests indicate the maximum charging rate caps at about 30W, even for the Pro Max model.

The integrated cable is a standout feature, commonly found in higher-end power banks, eliminating the need to carry an extra USB Type-C cable. This design is particularly convenient for travel, as the USB plug can be clipped onto the power bank to create a handy lanyard. The cable itself is robust, with a break strength of 44 pounds, while the lanyard loop, when attached to the power bank, has a break strength of 13 pounds.
