INIU 20,000mAh 65W USB Power Bank for $21.59
$44.99 save 52% $21.59 at Amazon (Use code 'WN9GQJRA')
This INIU power bank packs a substantial 20,000mAh (74Whr) battery. Accounting for 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 ensures fast charging for most gaming handhelds. Even devices with higher charging needs (ROG Ally X and Lenovo Legion Go) benefit from a charging speed matching their official power bricks. This is a significant advantage over similarly priced power banks typically limited to 20-30W Power Delivery.
It's also a great option for your Apple iPhone 16, as ChargerLAB testing indicates a maximum charging rate around 30W, even for the Pro Max.
