Joule Case Revolutionizes Clean, Portable Energy Options With Sigma Launch at 2022 CES

Sigma to deliver unrivaled battery cycle life, best-in-class AC output at minimal cost-per-watt hour

As the demand for clean, emission-free electricity surges across countless industries, Joule Case continues to evolve its products and advance the industry with the announcement of its Sigma line. From powering internationally known live events to transitioning food trucks to clean, green energy; Joule Case leveraged all of its use cases to meet and exceed industry standards with its Sigma line.


Joule Case Sigma includes a best-in-class, 3000-watt inverter for continuous AC output power with a surge capability of 4000 watts. Its proprietary battery management system extends the cycle life of batteries beyond 10 years, backed by a full warranty. The Sigma's PowerBlade™ System enables batteries and inverters to be stacked in any combination imaginable and is equipped with a patented 120-amp, 48-volt pass-through DC power/data bus. Joule Case can be charged from any power source including wall outlets, portable solar, roof mounted solar, and grid-scale solar farms. This provides endless options to meet any power demand in a compact design at $0.67 per watt hour, compared to $1.00 per watt hour of leading competitors.

Joule Case's Sigma launch follows an eventful year in powering live events and the evolution of the company. For the first time ever, large parts of Camp EDC were powered by clean, quiet and emission-free electricity via Joule Case at the EDC Vegas festival in October, 2021. Joule Case also powered all food trucks, multiple stages and several other power demands at Treefort MusicFest in September, 2021. Building on its recent momentum and success, Joule Case also launched a Wefunder campaign to further scale up to meet the demand for clean, safe, cost-efficient renewable power in the fast-growing event-power industry.
