Feature: 1. WORKING PARAMETER: The working voltage of the PTC car heating fan is 24V DC AC, and the steady state power is 100W±25%. 2. NYLON SHELL: PTC car air heater uses PA66 high temperature resistant reinforced nylon shell for safety protection, insulation and temperature resistance. 3. CONSTANT TEMPERATURE: PTC car air heating fan uses ceramic constant temperature heating technology to continuously output heat and automatically work at constant temperature. 4. FAST HEATING: PTC quickly converts electric energy into heat energy after power on, and you can feel the hot air the PTC heating fan brings within 30s. 5. COMPACT SIZE: PTC car fan heater is about the same size as the mouse, which can be placed in a narrow space for use, which is very space saving. 6. LONG SERVICE LIFE: Repeated turning on and off will not affect the service life of the heating fan, and continuous heat supply can continuously work for more than 10000 hours.
