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 2 hours for intense gameplay. This duration is suitable for a morning commute, but for longer sessions away from a wall outlet, such as during flights, a reliable power bank like the Iniu model featured here becomes essential. Although we have a list of our top recommended power banks for the Switch 2, the Iniu power bank is a solid choice, especially if the Switch 2 supports a higher charging output.
