This Iniu power bank comes with a substantial 20,000mAh, or 74Whr battery capacity. With an 80% power efficiency, you can expect to fully recharge your devices multiple times:

  • 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: 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 of Power Delivery ensures you can charge your Nintendo Switch (18W) and Steam Deck (40W) at their fastest possible rates. It's also an excellent choice for your Apple iPhone 16, as ChargerLAB has shown that the maximum charging rate for even the Pro Max model caps at about 30W.

One of the standout features of this power bank is the built-in cable, which is often seen on more expensive models. This means you don't need to carry your own USB Type-C cable. On the go, the USB plug can be clipped onto the power bank to create a convenient lanyard. The cable itself is durable, 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. While it's designed for portability, Nintendo claims a minimum battery life of just 2 hours for intense games. This is sufficient for a morning commute, but for longer flights or extended periods away from a power outlet, a reliable power bank is essential. Our top picks for the Switch 2 are detailed here, but the Iniu power bank highlighted in this article could be a great option if the Switch 2 supports a higher charging output.
