This Iniu power bank packs a substantial 20,000mAh (74Whr) battery. Considering approximately 80% power efficiency, expect these approximate full recharge cycles for your 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 Iniu power bank features three output ports: a 65W USB Type-C port, a 36W USB-Type-C port, and an 18W USB Type-A port. The 65W USB-C port is fast enough for most handhelds. Even for devices needing higher charging speeds (ROG Ally X and Lenovo Legion Go), it matches their official power brick. Power banks in this price range typically only support 20-30W Power Delivery, making this a superior deal.

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