Tripp Lite's Ultra-Compact Inverter is equipped with Ground Fault Circuit Interrupters (GFCI) for maximum safety and shock prevention. Fully OSHA-compliant and designed for use in mobile environments such as semi trucks and work/utility trucks, it efficiently provides quiet electricity to office equipment on the road or to power tools at a work site. The inverter supplies up to 1,800 watts of 120-v AC power to two GFCI-protected outlets from any 12-v battery or automotive DC source. Its high-efficiency operation conserves batteries to prolong run time.
