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

• 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: 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.
