The Iniu power bank features a substantial 20,000mAh, or 74Whr battery capacity. With an 80% power efficiency, you can expect to fully recharge your devices approximately:

  • 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

This power bank comes equipped with three output ports: one built-in 45W USB Type-C cable, one 45W USB Type-C port, and one USB Type-A port with up to 18W of power. The 45W Power Delivery is perfect for charging the Nintendo Switch (18W) and Steam Deck (40W) at their fastest rates. It's also an excellent choice for the Apple iPhone 16, as ChargerLAB has demonstrated that the maximum charging rate caps at around 30W, even for the Pro Max model.

The built-in cable is a standout feature often found on more expensive power banks, eliminating the need to carry your own 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 itself is robust, with a break strength of 44 pounds, while the lanyard loop, when clipped to the power bank, has a break strength of 13 pounds.

What about the new Nintendo Switch 2?

The Nintendo Switch 2 is set to launch on June 5, and while it's designed for portability, Nintendo has stated it will offer a minimum of 2 hours of battery life during intense gameplay. This is sufficient for a morning commute, but for longer sessions away from a power outlet, such as flights, a reliable power bank is essential. While we have a selection of recommended power banks for the Switch 2, the Iniu power bank highlighted here is a great option, especially if the Switch 2 supports higher charging outputs.
