Run two 18V tool batteries in parallel and double your runtime. The Double Battery Adapter connects two matching packs into one output, so the Volt Dropper, Volt Booster and the rest of the Volt range run twice as long on the batteries you already own. Ideal for long days off grid, powering a 12V fridge overnight, or keeping gear running

My husband was very impressed with the volt, to go with his new Milwaukee tools. He has not tried yet, but was very impressed that he could use it to run his fridge freezer. Thank you

Great product and works well, my only critique would be it is quite a bulky item compared to the charging unit and other accessories! Also be good to come with a bag for it all lol Works a treat though, Cheers

Easy enough to use without being clunky or unbalanced, did what I bought it to do in several applications so far!
