I am an Electronic Tech. Bought a cheap Chinese inverter (Krieger) for the price. Failed after 14 months. The Tripp Lite powers devices that the Chinese inverter would not. The Tripp lite is well made the Chinese inverter looked like a 6 year old assembled and soldered it (junk). Save yourself the trouble and but the Tripp Lite first wish I had. Better investment than other inverters on the market.
