This Iniu power bank features a substantial 20,000mAh (74Whr) battery capacity. 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 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 sufficient for fast charging most gaming handhelds. Even devices requiring higher charging rates (ROG Ally X and Lenovo Legion Go) benefit from a charging speed matching their official power bricks. Power banks in this price range typically only support 20-30W Power Delivery, making this an exceptional value.

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.
