This INIU power bank features a substantial 20,000mAh, or 74Whr battery capacity. With an 80% power efficiency, you can expect the following approximate full recharges for each 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 power bank is equipped with three output ports: one 65W USB Type-C port, one 36W USB-Type-C port, and one USB Type-A port with up to 18W of power. The 65W USB port can charge most gaming handhelds at their fastest rate, and for devices that support even 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 offer 20-30W of Power Delivery, making this deal stand out.

On a related note, this power bank is also an excellent choice for charging your Apple iPhone 16, as ChargerLAB has shown that its maximum charging rate is about 30W, even for the Pro Max model.
