## Customer Reviews

### ⭐⭐⭐⭐⭐ Good
*by A***B on March 18, 2026*

Works as expected

### ⭐⭐⭐⭐⭐ Couldn’t be easier.
*by S***S on December 19, 2025*

Works exactly as advertised - plug and play for more run time.

### ⭐⭐⭐⭐⭐ Dependable battery
*by A***R on July 3, 2025*

Battery extension works like it says gives you more time for usage of power station, charges fast and can be used separately as a stand alone power to charge a laptop or phone. Good for camping and road trips .I highly recommend.
