This Iniu power bank features a robust 20,000mAh, or 74Whr battery capacity. With an 80% power efficiency, you can expect the following number of full recharges for each device:

• Nintendo Switch (16Whr): about 3.7 times
• Steam Deck (40Whr): about 1.9 times
• Apple iPhone 16 (14Whr): about 4.2 times
• Apple iPhone 16 Plus (18Whr): about 3.3 times

The power bank comes equipped with three output ports: a built-in 45W USB Type-C cable, a 45W USB Type-C port, and a USB Type-A port with up to 18W of power. The 45W Power Delivery is sufficient to charge the Nintendo Switch (18W) and Steam Deck (40W) at their maximum rates. It's also an excellent choice for charging the Apple iPhone 16, as ChargerLAB has demonstrated that its maximum charging rate tops out at around 30W, even for the Pro Max model.

A standout feature of this power bank is its built-in cable, a convenience often found in newer, more expensive models. This eliminates the need to carry an additional USB Type-C cable. When you're on the move, the USB plug can be clipped onto the power bank to create a handy lanyard. The cable itself is durable, boasting a break strength of 44 pounds, while the lanyard loop, when attached to the power bank, has a break strength of 13 pounds.

What about the new Nintendo Switch 2?

The Nintendo Switch 2 is set to launch on June 5. While it's designed for portability, Nintendo has stated a minimum battery life of 2 hours for intense games. This should suffice for a morning commute, but for longer flights or extended time away from a power outlet, a reliable power bank is essential. Although we have a selection of top power banks for the Switch 2, the Iniu power bank featured here remains a solid option, especially if the Switch 2 supports higher charging outputs.
