This INIU power bank features a robust 20,000mAh, or 74Whr battery capacity. With an 80% power efficiency, here's how many full charges 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 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 is powerful enough to charge most gaming handhelds at their maximum speed. For devices like the ROG Ally X and Lenovo Legion Go that support even higher charging rates, this power bank 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 deal exceptionally good.

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