This INIU power bank comes with a robust 20,000mAh, or 74Whr battery capacity. With an 80% power efficiency, you can expect to fully recharge your gaming handhelds approximately:
- 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 is sufficient to 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 speed of their official power bricks. Typically, power banks in this price range only offer up to 20-30W of Power Delivery, making this deal exceptionally good.
On a related note, this power bank is also a great option for charging your Apple iPhone 16, as ChargerLAB has demonstrated that the maximum charging rate tops out at about 30W, even for the Pro Max model.
