Iniu 20,000mAh 45W USB Power Bank

This Iniu power bank features a robust 20,000mAh (74Whr) battery. With an estimated 80% efficiency, here’s how many full charges you can expect for each device:

Equipped with three output ports—one built-in 45W USB-C cable, one 45W USB-C port, and one 18W USB-A port—this power bank delivers fast charging for the Nintendo Switch (18W) and Steam Deck (40W). It’s also ideal for the iPhone 16, which supports up to 30W charging, as confirmed by ChargerLAB, even for the Pro Max model.

The integrated USB-C cable, a feature often found in premium power banks, eliminates the need to carry an extra cable. On the go, the USB plug clips to the power bank, creating a convenient lanyard. The cable is durable, with a break strength of 44 pounds, while the lanyard loop withstands 13 pounds when clipped.

What About the Nintendo Switch 2?

The Nintendo Switch 2, launching June 5, offers at least 2 hours of battery life for demanding games—sufficient for short commutes but not extended trips. For longer gaming sessions away from outlets, a reliable power bank is essential. While we recommend checking our top power banks for the Switch 2, this Iniu model is a strong contender, especially if the Switch 2 supports higher charging outputs.
