1、[Durable Material] Aluminum alloy shell, light weight, good thermal conductivity, can quickly reduce the temperature of components, work long hours are not affected. 2、[High Efficiency] Modified sine waves inverter, 220V for city power supply and power quality, intelligent filter, does not interfere with electrical appliances, protects electrical appliances. With high conversion efficiency (up to 95%), the low power consumption of the product itself can greatly extend battery life. 3、[Eight Bit Intelligent Protection] Overload protection, high voltage protection, low voltage protection, overheating protection, reverse connection protection, short circuit protection, overcurrent protection, intelligent chip control, perfect protection. 4、[Multifunctional] Intelligent temperature control fan makes the inverter more quiet. When the temperature is ≤45 ℃, the fan stops working; when the temperature is ≥45 ℃, the fan starts working. You can use electrical equipment, including TV / LED lights / LCD displays, especially inductive load appliances such as refrigerators, freezers, induction cookers. 5、[Buzzer Reminder] Once any protection of the inverter is triggered, the inverter will immediately disconnect the power, the load enters the protection mode and reminds people with a buzzer reminder.
