There are certain times when power is desperately needed. Aboard airplanes, for instance, and in places where there are no outlets, people need power to save lives and to keep things moving. In the past, it has been difficult to supply power to these places. Start Pac and other companies have begun to change that, though, developing new technologies to be used in the places where those technologies are most necessary. Their ground power units are known for reliability, and they have developed a range of different products to be used in specific environments.
