Originally priced at $44.99, you can save 52% and get it for $21.59 at Amazon by using the code 'WN9GQJRA'. This power bank features a robust 20,000mAh, or 74Whr battery capacity. Considering an 80% power efficiency, you can expect to fully recharge your gaming handhelds approximately as follows:

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

The INIU power bank comes equipped with three output ports: a 65W USB Type-C port, a 36W USB-Type-C port, and a USB Type-A port with up to 18W of power. The 65W USB port can charge most gaming handhelds at their fastest rate.

Typically, power banks in this price range only offer up to 20-30W of Power Delivery, making this deal stand out.

On another note, this power bank is also a great option for charging your Apple iPhone 16, as ChargerLAB tests show the maximum charging rate caps at around 30W, even for the Pro Max model.
