Product Description Size (approx.): 52 * 45CM / 20.47 * 17.71inch Color: Black, Coffee, Gray Power supply: 12V car single battery, 24V car -Double battery(The power supply can not be used in series. It is strictly forbidden to connect the 12V power supply to the 24V power supply. If the accident happens, all at your own risk.)Maximum power consumption: 36W 3W Minimum power consumption: 22W 3W Fuse: 7A Power cord (approx.): 115cm Material: polyester fiber Package content: 1 * car heating pad br/>1.Alloy Heating WireThe heating wire consists of more than ten copper-nickel alloy wires and 500D high-strength tensile and anti-ballistic wire. Each of the ten copper-nickel alloy wires is independent, and if one of them is cut, the product can work normally. 2.Safe to UseAlloy heating wire, intelligent temperature control, anti-freeze wire, switch connector, high temperature connector, anti-slip backing , Plush fabric, easy to attach. 3.Cold and DurableAntifreeze wire is specially designed for severe cold regions. The cold-resistant cable has the characteristics of wear resistance, cold resistance, tear resistance and high flexibility. It has good cold resistance and long-term use in low temperature environments without brittleness and cracking. 4.High temperature resistant flame retardant plug is safer to use Anti-slip particles on the back can effectively reduce seat cushion displacement to ensure safety and increase comfortable driving. Plush fabric is delicate and smooth, warm and comfortable, long-lasting warm for travel.5.Intelligent temperature control is saferWhen the seat cushion is heated to 60, the temperature control switch will turn off automatically and the heating pad will work no more. When the temperature drops to 40C, the thermostat will automatically close and start working again.
