1、Long Term Use: Using aluminum alloy shell, light weight, good thermal conductivity, can quickly reduce the temperature of components, long term work is not affected 2、Repair Sine Wave: Intelligent filtering, does not interfere with electrical appliances, and protects electrical appliances. High conversion efficiency, low power consumption can greatly extend battery life 3、Application: You can use electrical equipment, including TV, LED lights, LCD monitors, especially inductive load appliances such as refrigerators, freezers, induction cookers, etc. 4、8 Intelligent Protection: With overload, high voltage, low voltage, overheating, reverse polarity, short circuit, overcurrent, insurance protection, intelligent chip control, perfect protections 5、Make Quieter: The intelligent temperature controlled fan makes the inverter quieter, when the temperature is ≤45℃, the fan stops working, and when the temperature is ≥45℃, the fan starts to work 6、Buzzer Reminder: Once any protection of the inverter is triggered, the inverter will immediately disconnect the power supply, the load will enter the protection mode and remind people through the buzzer 1 x Power Inverters1 x Connecting Wire2 x Battery Clip1 x User Manual Item Type: DC to AC ConverterMaterial: Aluminum AlloyType: Repair Sine Wave InverterOutput Voltage Waveform: Repair Sine WavePower: 3000WOutput Voltage: 110VInput Voltage: 12VWeight: Approx. 775g / 27.34oz
