Scream Truck, a revolutionary on-demand ice cream service based out of New Jersey, was facing a challenge. Their traditional diesel generator was not only contributing to carbon emissions and noise pollution but also causing interruptions in their service due to the need for refueling and maintenance. These interruptions were costing them valuable time and money. They needed a sustainable, efficient, and reliable power solution to keep their truck on the road all day long.

Scream Truck explored various electric options, speaking with a variety of companies in search of the perfect solution. However, they frequently encountered solutions that failed to meet their specific needs, particularly in terms of supplying ample power for all-day operations. As Eric Murphy, CEO of Scream Truck described it on the Tech Bites podcast, when they discovered Joule Case, it seemed "too good to be true."
