The SSW-600-12A is an economical pure sine-wave DC-AC inverter that converts 12 Volts DC to 600 watts of AC power. Ideal for powering office equipment, television, DVD or Blu-Ray, video games, digital clocks and other sensitive loads from your car, truck, boat, RV or solar system batteries. Features Soft Start technology that gradually ramps-up voltage during inverter start-up eliminating failed cold starts under load. This eliminates almost all shutdowns from momentary overloads. Also features Low Interference Technology, which greatly improves the interference problems common with modified sine wave inverters. This allows you to enjoy a clean and powerful AC source free from signal interference that can occur with TV's, audio systems and radio equipment. Comes with USB Charging Port. Power mobile equipment such as cell phones, MP3 players, iPads, GPS systems and many other portable electronic devices.
