I operate high-tech electronics without any problems. Tower computer with 750 watt 8 GB RAM 3 GHz processor, Hp Laserjet 130n, 1500 watt microwave, large vacuum cleaner. two-door refrigerator. 2 laptops, TV, Blueray. I can't think of anything else to test this 3000 watt pure sine wave inverter. My 6 gallon air compressor put the inverter in an error state. I had to try.
