Pure sine wave inverter for laptops 2000W 12V DC to AC220V1、The pure sinusoidal inverter is a power conversion device that converts DC 12V to AC 110V / AC220V (optional). 2、The output AC power can be used in various types of equipment to stabilize the accurate output voltage. It is especially suitable for continuous use of laptops in cars. 3、Automatic multi-performance protection, support overload trip, over temperature trip, low voltage alarm, low voltage disable, high battery power off, short circuit protection, reverse polarity protection. 4、Multi-functional universal socket, easy to use, safe and fast. Suitable for vacations, work trips, family or outdoor emergency situations, outdoor activities and camping. 5、International universal safety AC socket for laptops, cell phones, digital cameras, televisions, video recorders, stereos, hand drills, rice cookers and refrigerators, as well as various types of instruments. 6、Specially designed durable aluminum alloy body provides advanced protection and easier cooling. 7、The built-in temperature control cooling fan is used to prevent the device from overheating. The cooling fan is normally started at 1/3 of the rated power of the inverter, and the conversion efficiency will rise after the cooling fan kicks on.
