Our Customer Reviews

  • Ricky H.

    Joule Case was able to deliver a product that supplies everything I need without a dirty generator.

    Joule Case is proving that you do not need dirty smelly gas generators anymore.

  • Matt Larsen

    Gas generators are the standard for food trucks, but they are noisy and smelly - notes of diesel don't pair well with coffee... Joule Case is a lot cleaner. My power needs are high and I needed a big system to power that for a 4-6 hour event. I chose Joule Case because as a mobile vendor, it allows me to serve people differently... It's more sustainable. It's the right choice for me and my business.

    Super impressed with your product and so easy to use. Joule Case was the easiest part of the wedding!

  • Dr. Sandro Olgiati

    Not too many people are willing to buy equipment until the last moment - until a crisis occurs. I am proactive in my medical practice and in my life in general. With the Joule Case battery we have, we would be comfortable with a power outage for many days.

  • John Fuhrman
    We love Joule Case! We've taken it camping, up to the cabin, and hunting. I don't have to deal with the noise and fumes from a generator anymore. The 1kwh battery system powers our camp for a weekend. We charged all our power tools, lights, and even an AC. With kids, dust, and weather, we have beaten the crap out of the thing and it keeps going.
