About the product Our interference antifreeze instrument contains a relay group, a high-voltage package, and a plastic shell. Function: No magnetic solar energy, but a lithium battery with a power storage function, with a switch, without fragrance tablets, a service life of 1-2 years, a power storage capacity of 55 mA, voltage and current power: 3V 55 mA, about 1W. It can keep the surrounding environment at a constant level of warmth and humidity, making the surrounding environment more comfortable, making it difficult for ice and frost to condense, thereby achieving the effect of snow removal. Its usage is very simple: first place the product in a stable position, then turn on the switch, activate the device, and the heat and moisture released by the instrument can heat and humidify, and melt ice and snow. The light will automatically go out after it is fully charged. This is a recycling of electricity and solar energy. It takes about half an hour to charge. It can be used for about 10-15 days after a charge. After turning on the switch, it flashes once every 5 seconds. After use, it can loosen the structure of water molecules, making it difficult for ice and snow outside the car to condense in winter, and keeping the car warm. It is a must-have item for driving a car in winter.
