1Long Term Use: Using aluminum alloy shell, light weight, good thermal conductivity, can quickly reduce the temperature of components, long term work is not affected 2Pure 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 3Application: You can use electrical equipment, including TV, LED lights, LCD monitors, especially inductive load appliances such as refrigerators, freezers, induction cookers, etc. 48 Intelligent Protection: With overload, high voltage, low voltage, overheating, reverse polarity, short circuit, overcurrent, insurance protection, intelligent chip control, perfect protections 5Make 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 6Buzzer 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 Item Type: DCtoACConverterMaterial: Aluminum AlloyType: Pure Sine Wave InverterOutput Voltage Waveform: Pure Sine WavePower: 3000WOutput Voltage: 110VInput Voltage: 12eight: Approx. 775g / 27.34oz 1 x Power Inverters1 x Connecting Wire2 x Battery Clip1 x User Manual
