This Iniu power bank packs a substantial 20,000mAh (74Whr) battery. Considering approximately 80% power efficiency, expect these approximate full recharges:
- 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: 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 gaming handhelds. Even devices with higher charging needs (ROG Ally X and Lenovo Legion Go) benefit from a charging rate matching their official power bricks. Power banks in this price range usually only support 20-30W Power Delivery, making this a standout deal.
Incidentally, this power bank is also ideal for charging your Apple iPhone 16, as ChargerLAB tests indicate a maximum charging rate around 30W, even for the Pro Max.
