This INIU power bank features a substantial 20,000mAh, or 74Whr battery capacity. Considering 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 is equipped with 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 is capable of charging most gaming handhelds at their fastest rate. For devices that support even higher charging rates like the ROG Ally X and Lenovo Legion Go, it matches the charging speed of their official power bricks. Typically, power banks in this price range only offer up to 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 indicated that the maximum charging rate for even the Pro Max model caps at about 30W.
