The Solpowben 38800mAh Solar Power Bank is a rugged pocket-sized battery pack with two 5V USB-A outputs, USB-C input and output, a built-in LED flashlight and a carabiner. It is IP65-rated for water and dust and weighs 9 oz. The 38800mAh figure is far larger than the cell inside a 9 oz pack, so expect roughly one to two phone charges, not eight. At $13.98 at Walmart as of November 5, 2026, it sits at the low end of its recent range and is cheap enough to treat as a backup rather than a main charger.

Ratings average 3.6 out of 5 from 492 buyers. Owners like the price, the flashlight and the rugged shell, but many report the battery holds far less charge than advertised and the solar panel barely moves the needle.
