This INIU power bank features a substantial 20,000mAh, or 74Whr, battery capacity. Considering an 80% power efficiency, here's how many full recharges you can expect for each gaming handheld:

The power bank comes 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 is sufficient to charge most gaming handhelds at their fastest rate. For devices like the ROG Ally X and Lenovo Legion Go, which can accept even higher charging rates, this power bank matches the charging speed of their official power bricks. Typically, power banks in this price range only support up to 20-30W of Power Delivery, making this an exceptional deal.

Additionally, this power bank is a great option for charging your Apple iPhone 16, as ChargerLAB has shown that the maximum charging rate for these devices caps at about 30W, even for the Pro Max model.
