If you’re looking for an affordable power bank that will fast charge your Nintendo Switch, Steam Deck, or Asus ROG Ally gaming handheld, then check out today’s deal. Amazon has the INIU 20,000mAh Power Bank with up to 65W of Power Delivery over USB Type-C for only $21.59 after you clip the 40% off coupon on the product page (if you don’t see it, try applying promo code “WN9GQJRA“). INIU power banks have solid reviews and are less expensive than equivalent Anker models. This particular model has 2,600 reviews on Amazon with a 4.5 star average and a Fakespot “B” rating.
Iniu 20,000mAh 65W USB Power Bank for $21.59
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 times
The 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 at least matches the same charging rate as 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.
Need something even cheaper?
You can grab this 10,000mAh power bank for only $8.99 after you clip the 10% off and 40% off clippable coupons on the product page. We very rarely see 10,000mAh power banks listed for under $10 so grab this one while you can. This will charge a Nintendo Switch from 0% to 100% about 1.9 times.
