This INIU power bank features a substantial 20,000mAh (74Whr) battery capacity. Considering 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

Equipped with three output ports—one 65W USB Type-C, one 36W USB-Type-C, and one USB Type-A with up to 18W—the 65W 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 speed of their official chargers. This deal stands out because most power banks in this price range typically offer only 20-30W of Power Delivery.

Additionally, this power bank is a great option for charging your Apple iPhone 16, as ChargerLAB tests indicate a maximum charging rate of around 30W, even for the Pro Max model.
