This INIU power bank features a substantial 20,000mAh (74Whr) battery capacity. Considering approximately 80% power efficiency, expect these approximate full recharges:

  • Nintendo Switch (16Whr): about 3.7 times
  • Steam Deck (40Whr): about 1.9 times
  • Asus ROG Ally (40Whr): about 1.9 times
  • Asus ROG Ally X (80Whr): about 1 time
  • Lenovo Legion Go (50Whr): about 1.5 times

The power bank includes three output ports: a 65W USB Type-C port, a 36W USB-Type-C port, and an 18W USB Type-A port. The 65W USB-C port ensures the fastest charging for most handhelds. Even for devices requiring higher charging rates (ROG Ally X and Lenovo Legion Go), it matches the charging speed of their official power bricks. Power banks in this price range typically only support 20-30W Power Delivery, making this an exceptional value.

Incidentally, this power bank is also ideal for charging your Apple iPhone 16, as ChargerLAB testing indicates a maximum charging rate of around 30W, even for the Pro Max model.
