INIU 20,000mAh 65W USB Power Bank

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

Originally priced at $44.99, this power bank is now available for a 52% discount, bringing the price down to $21.59. With a 20,000mAh (74Whr) battery capacity and an 80% power efficiency, you can expect to fully recharge your devices approximately as follows:

• 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 higher charging rates like the ROG Ally X and Lenovo Legion Go, it matches the charging speed of their official power bricks. Typically, power banks in this price range only offer up to 20-30W of Power Delivery, making this deal particularly noteworthy.

Additionally, this power bank is an excellent option for charging your Apple iPhone 16, as ChargerLAB tests indicate that its maximum charging rate tops out at about 30W, even for the Pro Max model.
