    The Solution

    Results

    "I’ve been looking for a way to reduce our reliance on diesel for a while, so when the chance to use the Ampd Enertainer came along, I was excited. The result delivered beyond the original idea. Not only did it reduce our emissions but also our operational costs and noise. It also proved extremely easy to use, so the project team was very pleased. In addition, we conducted some trials to test the recharging efficiency and the energy storage capacity of the Enertainer. The results exceeded our expectations."
