We’ll Buy Back Your Battery
Typically when batteries become unusable, people throw them away in their household trash. They go to landfills and become hazardous to oceans, lakes, rivers, and soil. Ultimately being harmful to the environment and our health. We chose to change the story for our batteries. When you’re done with your Joule Case battery, we will buy the battery back from you.

Adaptable Battery Chemistry
We’re always looking ahead. That’s why we designed our batteries to evolve with the industry. Our power systems are chemistry-agnostic, meaning they can be interchangeable as energy sources improve and change.

Innovations
We created the next generation of portable power. Take power off the grid for camping, events, food trucks, and off-grid backup. The stackable, flexible, portable design gives you the control to literally power anything you want.
