Great battery for backup especially for devices that have bad batteries built in
Amazon Vine Customer Review—June 4, 2025
I use these as a power source for FM radio speakers I have all around my property that are powered by solar. At half volume using 5w speakers I get 24+ hours of playtime. You can daisy chain them together to increase power storage. The energy (electrons) will gather closest to the load. Once the batteries sense voltage on the line from the solar panel they turn on. People throw the bluetooth/fm speakers away once the battery degrades (~2years). I take the parts out of them and build my own that have REPLACABLE batteries. These are a good option if your battery dies in your bluetooth speaker. Read more

Works well. Typical Capacity. No issues. Good price.
Joe H—January 18, 2025
No dislikes. I don't need a digital charge indicator. The led lights are adequate and don't fail or dim. Like. Simple and works at a good price. Discharge capacity was typical for a10k mah power banks. 33,000 mah. That's actual after taxes (circuitry losses). Read more

Not compatible with my Milwaukee jacket but work ok as spare power packs
jeff f—November 14, 2024
I got these as backups for my Milwaukee heated jacket not realizing the jacket has a round power connector that is not compatible with these packs. Should have checked first, my bad. Otherwise, they have worked just fine as a backup supply for various electronics around the house. Not too heavy or bulky for the AHs they provide. USB-A and C ports and indicator lights for charge capacity. They come with a cord for each one for charging or supplying power, USB-C. You can use other cords for your older Apple or Android products. So far they are working just fine. Read more
