Extend your Nintendo Switch 2 playtime
The Nintendo Switch 2 is now available, making it an ideal time to pick up a power bank if you don't already own one. Nintendo officially states the Switch 2's battery lasts between 2 to 6.5 hours on a single charge.
The Switch 2 houses a 5,220mAh battery—only slightly larger than the original Switch's 4,310mAh cell. A 10,000mAh power bank can more than double your total playtime. Furthermore, the 45W Power Delivery specification ensures this power bank charges the Switch 2 at its maximum possible speed.
The Iniu power bank provides three output options: one built-in 45W USB-C cable, one 45W USB-C port, and one standard USB-A port. The 45W Power Delivery is sufficient to fast-charge the Nintendo Switch (18W) and Steam Deck (40W). It's also a strong choice for the Apple iPhone 16; ChargerLAB testing indicates a maximum charging rate of around 30W, even for the Pro Max model.
The integrated cable is a convenient feature more common on newer, often pricier power banks, eliminating the need to carry a separate USB-C cable. For portability, the USB plug clips onto the power bank to form a handy lanyard. The cable itself is robust with a break strength of 44 pounds, and the lanyard loop, when attached, holds up to 13 pounds.

Should You Shop Now or Wait for Prime Day?
The decision is more nuanced than it seems. Currently, this power bank deal appears superior to what we typically see during Amazon's 2025 Prime Day sales, making it a worthwhile purchase to secure while the discount lasts.
