Carmaer Universal 12V to 220V 2000W Car LCD Display Inverter Household Power Converter 1. The car inverter circuit has automatic protection for overload, overvoltage, overtemperature, and short circuit. The aluminum alloy shell is sturdy, beautiful, lightweight, convenient and practical. 2. Intelligent dual digital display inverter, support solar panel to switch battery. 3. It has over temperature protection, input low voltage protection, input high voltage protection, overload protection, short circuit protection, etc. to ensure that the inverter is better protected during use. 4. Intelligent digital display allows you to keep track of the output voltage value. 5. Intelligent fan, high-speed heat dissipation, controlled by temperature, when the inverter starts, the fan will automatically start, the higher the temperature, the faster the fan speed. 6. The buzzer device reminds that when the inverter is in use, when the power supply battery is insufficient and the voltage is insufficient, the inverter will emit a buzzer warning sound to protect electrical appliances from damage due to insufficient voltage. 7. Good heat dissipation comes from design and materials. Surface concave-convex design + aluminum alloy casing effectively improves heat dissipation. Thickened aluminum alloy casing greatly improves heat dissipation and compression resistance. 8. Equipped with cigarette lighter and alligator clip power cable. 9.
