Iniu 20,000mAh 65W USB Power Bank for $21.59
INIU 20,000mAh 65W USB Power Bank
This Iniu power bank boasts a generous 20,000mAh, or 74Whr battery capacity. If you factor in 80% power efficiency, here are the approximate number of times you can fully recharge each gaming handheld:
Nintendo Switch (16Whr) about 3.7 timesSteam Deck (40Whr) about 1.9 timesAsus ROG Ally (40Whr) about 1.9 timesAsus ROG Ally X (80Whr) about 1 timeLenovo Legion Go (50Whr) about 1.5 timesThe Iniu power bank has 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 enough to charge most gaming handhelds at their fastest rate. For the ones that can accept an even greater charging rate (ROG Ally X and Lenovo Legion Go), it matches the charging rate of the offical power brick that they come with. Normally power banks in this price range only support up to 20-30W of Power Delivery, which is why this is a better than average deal.
On a related note, this power bank is also a solid choice for charging your Apple iPhone 16, since ChargerLAB has shown that the maximum charging rate caps at about 30W, even for the Pro Max model.
