This INIU power bank comes with a hefty 20,000mAh (74Whr) battery capacity. Considering an 80% power efficiency, you can expect to fully recharge your gaming handhelds approximately:

• Asus ROG Ally (40Whr): about 1.9 times
• Asus ROG Ally X (80Whr): about 1 time

The power bank is equipped with three output ports: a 65W USB Type-C port, a 36W USB-Type-C port, and a USB Type-A port delivering up to 18W. The 65W USB port is capable of charging most gaming handhelds at their fastest rate. Even for devices like the ROG Ally X and Lenovo Legion Go, which can handle higher charging rates, this power bank matches the performance of their official power bricks. Typically, power banks in this price range only offer up to 20-30W of Power Delivery, making this deal exceptionally appealing.

On another note, this power bank is also an excellent choice for charging your Apple iPhone 16, as ChargerLAB tests indicate a maximum charging rate of about 30W, even for the Pro Max model.
