What About the Upcoming Nintendo Switch 2?

The Nintendo Switch 2 is set to launch on June 5, and while it promises improved performance and graphics, battery life remains a concern. Nintendo estimates as little as 2 hours of gameplay during intensive sessions. That may be enough for short commutes, but for longer trips or all-day use, a powerful external charger like this Iniu model could become essential. While we await official details about its charging specs, this power bank is a smart investment in case the new Switch supports higher wattage input.
