This INIU power bank features a substantial 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 capable of charging most gaming handhelds at their fastest rate. For devices that can accept higher charging rates (like the ROG Ally X and Lenovo Legion Go), it matches the charging rate of their official power bricks. This is a superior deal, considering most power banks in this price range only offer up to 20-30W of Power Delivery.

Additionally, this power bank is an excellent choice for charging your Apple iPhone 16, as ChargerLAB has shown that its maximum charging rate tops out at about 30W, even for the Pro Max model.
