This INIU power bank features a generous 20,000mAh, or 74Whr, battery capacity. With an 80% power efficiency, here's how many times you can fully recharge 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 includes 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 sufficient to charge most gaming handhelds at their fastest rate. For devices like the ROG Ally X and Lenovo Legion Go, which can handle higher charging rates, this power bank matches the charging rate of their official power bricks. This deal is exceptional because power banks in this price range typically only support up to 20-30W of Power Delivery.

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