This INIU power bank features a substantial 20,000mAh (74Wh) battery capacity. Accounting for roughly 80% power efficiency, here's how many full charges you can expect for popular gaming handhelds:
Nintendo Switch (16Wh): Approximately 3.7 chargesSteam Deck (40Wh): Approximately 1.9 chargesASUS ROG Ally (40Wh): Approximately 1.9 chargesASUS ROG Ally X (80Wh): Approximately 1 chargeLenovo Legion Go (50Wh): Approximately 1.5 charges
The power bank includes three output ports: one 65W USB-C, one 36W USB-C, and one 18W USB-A port. The 65W USB-C port delivers enough power for maximum-speed charging on most gaming handhelds. For devices like the ROG Ally X and Lenovo Legion Go that can accept higher wattage, it at least matches the charging speed of their included official power adapters. Power banks in this price range typically max out at 20-30W Power Delivery, making this deal particularly noteworthy.
It's also a great choice for charging recent Apple iPhones, including the iPhone 16 Pro Max, as testing by ChargerLAB indicates their peak charging rate caps around 30W.
