REDARC?s 400W Pure Sine Wave Inverter makes it possible to plug in anywhere and power all your 110V luxuries from home. With a 400W inverter in your off-grid setup, you can charge your phones, cameras, laptops and speakers, and run GPS and bi-pap machines, without fear of damaging your appliances. Utilizing a Pure Sine Wave output, the 400W inverter ensures appliances run smoothly and efficiently, producing less heat and noise. Slimmer and lighter, REDARC inverters feature multiple levels of protection including overload, short circuit and an over temperature and load controlled cooling fan, which is engaged when power consumption reaches a certain level. This ensures the inverter can work comfortably in even the harshest conditions. Control your Pure Sine Wave Inverter from up to 26 feet away with a?remote on off switch, sold separately. This allows the control of an inverter and is designed so the inverter can be installed out of sight in your RV or truck.
