This INIU power bank comes equipped with 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 features 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 can charge most gaming handhelds at their fastest rate. For devices like the ROG Ally X and Lenovo Legion Go, which can accept higher charging rates, this power bank matches the charging speed of their official power bricks. Typically, power banks in this price range only support up to 20-30W of Power Delivery, making this an exceptional deal.

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