With the prices on imported goods continuing to rise, I don’t see as many 20,000mAh power banks under $25 anymore. Fortunately, Amazon’s Memorial Day Sale does drop the price on one such battery. For a limited time, you can pick up the Iniu 20,000mAh 22.5W Power Bank for just $16.82 after an automatic 49% coupon is applied during checkout. Better yet, you don’t need to be an Amazon Prime member to get in on the discount.

Iniu 20,000mAh 22.5W Power Bank
8
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 times
- Nintendo Switch 2 (19Whr) about 3.1 times
- Steam Deck (40Whr) about 1.5 times
- Apple iPhone 17 (14.3Whr) about 4.1 times
- Apple iPhone 17 Pro Max (19.8Whr) about 3 times
The Iniu power bank has three total ports: two USB Type-C and one USB Type-A. The 22.5W power output from the USB Type-C port is enough to charge the Nintendo Switch and Nintendo Switch 2 at their maximum rate, which means you can play and charge simultaneously. The included cable is a popular feature on newer power banks because you no longer have to bring along your own USB Type-C cable.
