Our take on the INIU Slim 20,000mAh
The INIU Slim 20,000mAh is a 45W power bank with a built-in braided USB-C cable, for charging a phone or tablet on an IRL stream. At a tracked $29.99 it sits in the lower half of its $28.47 to $32.99 range since July 2026, so there is little reason to wait.
The listing says it is 30% smaller than other 20,000mAh banks, and it can charge three devices at once. The built-in cable is rated for 10,000 bends. A digital display and flashlight are included, and it is TSA compliant. Rated 4.3 across 2,542 retailer ratings, lower than the P512.
