Easy to install and use: Small and compact design for convenient placement. Fix the heater on a nonslip mat or use doublesided tape for a simple, tool setup. Energyefficient performance: Outlets provide long transmitting distance and wide coverage, offering effective heat distribution with low power consumption. 23 practical use scenarios: Winter mornings: rapidly remove frost from the windshield to enable immediate driving. Humid or foggy days: defog side and rear windows for improved visibility. Short stops or chilly starts: quickly create a comfortable cabin area without waiting for the vehicle's main heater. Key attributes addressed: function (defog, defrost, quick visibility), compatibility (designed to mimic standard car vent adjustment), size (compact and portable), ease of installation (nonslip mat or doublesided tape), and performance (longrange outlets with energyefficient operation).
