Customer Reviews
Nice box-could be even better By
I recently bought a PWRbox2 for my Bioenno 1240A battery. Nice box from a feature and usability perspective. One issue I see is with the battery meter. It's control buttons are on the back of the meter. Since the meter is mounted in the box cover, to access the buttons requires opening the top. While using the box, this is not impractical and might not be possible depending on what is plugged in. Using a different battery meter with controls on its face would make this a spectacular power box. I will use this box because it is good and works well for me. It could be even better.

Check interior dimensions By
The battery box has many positive features. Check the internal dimensions and compare with the size of the battery you plan to carry. Some are larger in width or height and may not fit.

Portable Power & Ready-To-Go By
This is the second Power Box I have bought. I use them both for different Amateur radio go kits. I use one for my UHV/VHV radio and one to power my HF/6m radios and peripherals. Even with the batteries inside I still have some room for small things inside the box. They are prefect to use in an emergency or even Field Day. My wife can setup one in one location and I can setup in a different location and using the Bioenno battery they are prefect for how we use them.
