Towable generators are the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. Due to its nature of tow ability it is ideal for small and large job sites. Since multiple electric equipment units need to work at the same time to maximize work capacity, hence it is the ideal choice for any job site.
Portable generators can power things such as most standard 120/240v electric power tools, lighting equipment, fans, blowers. Some of them have automatic idle control as fuel conservation and noise control features. They are typically small enough to be carried by one or two adults.
