The DuroStar DS4000S movable generator is the best purchase for this price. This generator delivers the best results when it comes to the power supply for each dollar you pay. With a power capacity ranked at 3300 watts of running power and 4000 watts of surge power, this machine ensures a stable supply of power to operate the major part of your devices at home. Besides, it is the best choice for camping and RV. It can also provide power for heavy-duty devices including HVAC systems at home and in your RV.
