Extend your Nintendo Switch 2 playtime
The Nintendo Switch 2 is now available, and if you don’t own a power bank yet, now is a great time to get one. According to Nintendo, the Switch 2 offers between 2 and 6.5 hours of playtime per charge. With a 5,220mAh battery—only slightly larger than the original Switch's 4,310mAh—a 10,000mAh power bank will more than double your total playtime. Plus, the 45W Power Delivery ensures the Switch 2 charges at its maximum speed, so you can play while it's charging.
This Iniu model includes three output options: a built-in 45W USB-C cable, a 45W USB-C port, and a USB-A port. The 45W Power Delivery is sufficient to fast-charge the Nintendo Switch (18W) and Steam Deck (40W). It’s also a great choice for the Apple iPhone 16, since ChargerLAB tests show it peaks at around 30W, even for the Pro Max model.
Built-in cables are a popular addition on many newer—often more expensive—power banks, since you won’t need to carry a separate USB-C cable. Here, the integrated cable can charge both your gadgets and the power bank itself.
