The Powermax XP3500 is a six and a half horsepower, air-cooled OHV engine power generator that has a four-stroke motor. It also features low oil shut off mechanism that keeps you from dangerously operating the unit when it is already low in oil. It has two fully protected 120-volt power outlets and one twist lock outlet capable of producing electricity at 120 or 240 volts, depending on your needs.

It boasts of an eight-hour run time when its all steel 3.2-gallon fuel tank is full. The fuel tank features an ez-read gauge so you will always know how much fuel you are running on. The Powermax 3500 is equipped with a super quiet muffler system than greatly reduces engine noise and is therefore ideal to use at campsites. RPM is held at a constant level even when powering heavy loads, which saves on fuel and greatly reduces noise levels.
