INIU 20,000mAh 65W USB Power Bank for $21.59

$44.99 $21.59 at Amazon (Use code 'WN9GQJRA')

This Iniu power bank packs a substantial 20,000mAh (74Whr) battery. Considering approximately 80% power efficiency, here's the estimated number of full charges for various gaming handhelds:

• Nintendo Switch (16Whr): ~3.7 times
• Steam Deck (40Whr): ~1.9 times
• Asus ROG Ally (40Whr): ~1.9 times
• Asus ROG Ally X (80Whr): ~1 time
• Lenovo Legion Go (50Whr): ~1.5 times

The Iniu power bank features three output ports: a 65W USB Type-C port, a 36W USB-Type-C port, and an 18W USB Type-A port. The 65W USB-C port is powerful enough for rapid charging of most gaming handhelds. Even devices requiring higher charging speeds (ROG Ally X and Lenovo Legion Go) will charge at a rate matching their official power bricks. Power banks in this price range typically only support 20-30W Power Delivery, making this an exceptional value.

Incidentally, this power bank is also a great option for charging your Apple iPhone 16, as ChargerLAB testing indicates a maximum charging rate of around 30W, even for the Pro Max model.
