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-C port, a 36W USB-C port, and an 18W USB-A port. The 65W USB-C port is fast enough for most handhelds. Even for devices needing higher wattage (ROG Ally X and Lenovo Legion Go), it matches their official power brick's output. Power banks in this price range usually only offer 20-30W Power Delivery, making this a great deal.
Incidentally, this power bank is also excellent for charging your Apple iPhone 16, as ChargerLAB tests show a maximum charging rate around 30W, even for the Pro Max.
