Amazon is offering the INIU 20,000mAh Power Bank with up to 65W of Power Delivery over USB Type-C for just $21.59. To snag this price, make sure to clip the 40% off coupon on the product page or use the promo code "WN9GQJRA" if the coupon isn't visible.

This specific model boasts 2,600 reviews on Amazon with a 4.5-star average and a "B" rating from Fakespot.

Originally priced at $44.99, you can now save 52% and get it for $21.59 at Amazon with the code 'WN9GQJRA'. This power bank offers a substantial 20,000mAh, or 74Whr battery capacity. Assuming an 80% power efficiency, here's how many full charges 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 INIU 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 capable of charging most gaming handhelds at their fastest rate. For devices that support higher charging rates like the ROG Ally X and Lenovo Legion Go, this power bank matches the charging speed of their official power bricks. This deal is particularly appealing because power banks in this price range typically only support up to 20-30W of Power Delivery, making this a better-than-average offer.

On a related note, this power bank is also an excellent choice for charging your Apple iPhone 16, as ChargerLAB has confirmed that the maximum charging rate for these devices caps at around 30W, even for the Pro Max model.
