This INIU power bank features a robust 20,000mAh, or 74Whr battery capacity. With 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 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 that support even higher charging rates, like the ROG Ally X and Lenovo Legion Go, this power bank matches the charging speed 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 another note, this power bank is also an excellent choice for charging your Apple iPhone 16, as ChargerLAB has demonstrated that its maximum charging rate tops out at around 30W, even for the Pro Max model.
