INIU 20,000mAh 65W USB Power Bank

$44.99 save 52% - $21.59 at Amazon - Use code 'WN9GQJRA'

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

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

The power bank features 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 that can handle an even higher charging rate, like the ROG Ally X and Lenovo Legion Go, it matches the charging speed of their official power bricks. Typically, power banks at this price point only support up to 20-30W of Power Delivery, making this deal better than average.

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