INIU 20,000mAh 65W USB Power Bank for $21.59

$44.99 $21.59 at Amazon Use code 'WN9GQJRA'
This Iniu power bank features a substantial 20,000mAh (74Whr) battery capacity. Considering approximately 80% power efficiency, expect these approximate full recharge counts 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 includes 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 to charge most gaming handhelds at their maximum speed. Even for devices requiring higher charging rates (like the ROG Ally X and Lenovo Legion Go), it matches the charging speed of their official power bricks. Power banks in this price range typically only support 20-30W Power Delivery, making this a superior deal.
Incidentally, this power bank is also ideal for charging your Apple iPhone 16, as ChargerLAB testing indicates a maximum charging rate of approximately 30W, even for the Pro Max model.
