This Iniu power bank comes equipped with a hefty 20,000mAh, or 74Whr battery capacity. Assuming an 80% power efficiency, here’s how many full charges you can expect 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 features 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. With 45W Power Delivery, it can charge the Nintendo Switch (18W) and Steam Deck (40W) at their maximum speeds. It's also a great option for your Apple iPhone 16, as ChargerLAB tests indicate that even the Pro Max model tops out at about 30W.

The integrated cable is a standout feature, often found in more expensive power banks, eliminating the need to carry an extra USB Type-C cable. On the go, the USB plug can be clipped onto the power bank to create a convenient lanyard. The cable itself is robust, with a break strength of 44 pounds, and the lanyard loop has a break strength of 13 pounds when attached to the power bank.

What about the new Nintendo Switch 2?

The Nintendo Switch 2 is set to launch on June 5, and while it's designed for portability, Nintendo promises a minimum of 2 hours of battery life during intensive gaming sessions. This should be sufficient for a morning commute, but for longer trips or extended play away from an outlet, a reliable power bank is essential. While our list of top power banks for the Switch 2 is available, the Iniu power bank featured here is a strong contender, especially if the Switch 2 supports higher charging rates.
