This Iniu power bank features a substantial 20,000mAh (74Wh) battery. Factoring in approximately 80% power efficiency, here is how many full charges it can provide for popular devices:

Nintendo Switch (16Wh): About 3.7 times
Nintendo Switch 2 (19Wh): About 3.1 times
Steam Deck (40Wh): About 1.9 times
Apple iPhone 16 (14Wh): About 4.2 times
Apple iPhone 16 Plus (18Wh): About 3.3 times

*Apple iPhone 17 models feature a slightly higher battery capacity than the iPhone 16.

The Iniu power bank offers three output options: a built-in 45W USB-C cable, a separate 45W USB-C port, and an 18W USB-A port. The 45W Power Delivery is sufficient for fast-charging both the Nintendo Switch (18W) and Steam Deck (40W). It's also an excellent choice for the iPhone 16, as ChargerLAB testing shows the maximum charging rate caps around 30W, even for the Pro Max model.

The built-in cable, a feature often found on more expensive models, eliminates the need to carry a separate USB-C cord. The plug can be attached to the power bank to form a convenient carrying lanyard. The cable itself is durable, with a tested break strength of 44 pounds, and the lanyard loop has a break strength of 13 pounds.
