This INIU power bank comes with a 20,000mAh (74Whr) battery capacity. With an 80% power efficiency, here's how many full recharges you can expect for each gaming handheld:

• Nintendo Switch (16Whr): about 3.7 times
• Steam Deck (40Whr): about 1.9 times
• Asus ROG Ally (40Whr): about 1.9 times
• Asus ROG Ally X (80Whr): about 1 time
• Lenovo Legion Go (50Whr): about 1.5 times

The power bank features three output ports: one 65W USB Type-C port, one 36W USB Type-C port, and one USB Type-A port with up to 18W of power. The 65W USB port can charge most gaming handhelds at their fastest rate. For devices like the ROG Ally X and Lenovo Legion Go, which support higher charging rates, this power bank matches the speed of their official power bricks. Typically, power banks in this price range only offer 20-30W of Power Delivery, making this an exceptional deal.

On a related note, this power bank is also an excellent choice for charging your Apple iPhone 16, as ChargerLAB has shown that the maximum charging rate caps at about 30W, even for the Pro Max model.
