List: $44.99 | Save 52% | $21.59 at Amazon | Use code 'WN9GQJRA'
This INIU power bank features a substantial 20,000mAh (74Wh) capacity. Factoring in roughly 80% power efficiency, here are the estimated full recharges you can expect for popular handhelds:
Nintendo Switch (16Wh): about 3.7 times
Steam Deck (40Wh): about 1.9 times
ASUS ROG Ally (40Wh): about 1.9 times
ASUS ROG Ally X (80Wh): about 1 time
Lenovo Legion Go (50Wh): about 1.5 times
The power bank offers three output ports: one 65W USB-C, one 36W USB-C, and one 18W USB-A port. The 65W USB-C port is sufficient for rapid charging on most gaming handhelds. For devices like the ROG Ally X and Legion Go that can accept higher wattage, it matches the charging speed of their included wall adapters. Typically, power banks in this price range only support 20-30W Power Delivery, making this a standout deal.
This power bank is also a great option for charging the latest iPhone 16 models, as ChargerLAB testing indicates a maximum charging rate of about 30W, even for the Pro Max.
