OUPES B2 Multi-functional Extra Battery

This expansion battery works great. Keeps my spare freezer and fridge going with Mega1. I am glad Oupes designed the battery with solar input and can add solar panels to keep unit charged and going. Plus use battery on its own to power my 12-volt fridge while travel. Oupes designed products that work. I am very happy with products and service.

So far so good

What a beast i did a test and it covers everything from refrigerator to 8000 window unit on down awesome
