Voltmaster inverter generators are perfect for the RV or campsite or wherever you want all the conveniences of home. These generators produce a pure AC sine wave at a steady 60 cycles making them well suited for running all types of sensitive electronic equipment as well as microprocessorcontrolled appliances and tools. A high-efficiency engine produces low emissions. All generators meet EPA and CETL standards. A sophisticated smart throttle system varies the engine speed according to the load resulting in lower fuel consumption. The generators feature overload and low oil level shutdown protection.
