This Iniu power bank comes with a hefty 20,000mAh, or 74Whr battery capacity. When considering an 80% power efficiency, here's how many full charges you can expect 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 Iniu power bank features 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 is powerful enough to charge most gaming handhelds at their fastest rate. For devices like the ROG Ally X and Lenovo Legion Go, which can accept higher charging rates, it matches the charging speed of their official power bricks. This deal is exceptional because power banks in this price range typically only support up to 20-30W of Power Delivery.

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