Our interference antifreeze devices include relay sets, high voltage packages, and plastic housing. Function: No magnetic solar energy, battery storage function is lithium battery, with switch, without fragrance, service life of 1-2 years, storage capacity is 55 mA, voltage and current power: 3V 55 MA, about 1W. It can keep the surrounding environment at a constant level of warm humidity, making the surrounding environment more comfortable, making it difficult for ice and frost to condense, so as to achieve the effect of snow removal. Its use method is very simple: first put the product in a stable position, then turn on the switch, activate the device, the heat energy and moisture released by the instrument can be heated and humidified, and the snow and ice can be fused. It will automatically turn off the light after it is full, which is the recycling of electricity and solar energy, it can be charged for about half an hour, and it can be used for about 10-15 days once it is charged. After opening the switch, it flashes once in 5 seconds. After use, it can loosen the structure of water molecules, make it difficult for the snow and ice outside the car to condense in winter, keep the car warm, and it is an essential item for driving a car in winter.
