This INIU power bank features a robust 20,000mAh, or 74Whr battery capacity. With an 80% power efficiency, you can expect the following full recharges 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 INIU power bank includes three output ports: a 65W USB Type-C port, a 36W USB-Type-C port, and a 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 that support higher charging rates like the ROG Ally X and Lenovo Legion Go, it matches the charging rate of their official power bricks. Typically, power banks in this price range only offer 20-30W of Power Delivery, making this deal particularly noteworthy.

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 for even the Pro Max model caps at about 30W.
