Keep your vehicle comfortable and safe in cold or foggy conditions. This compact, durable 12V/24V car heater/defogger provides targeted hot air or a cool fan option to quickly clear windshields and warm the cabin. Key benefits Faster visibility and safer driving: switches between hot and natural (cool) airflow to defrost or defog windshields and windows. Reliable and safe operation: ABS housing, a robust cable, integrated fuses and automatic power-off protection reduce risk of damage and electrical faults. Easy to aim and install: includes a rotatable mounting bracket so you can position airflow where it’s needed. Features and specifications Material: durable ABS construction and a reinforced power cable for long service life. Safety: built-in fuses and automatic shutoff protect the device and your vehicle’s electrical system. Modes: two selectable modes — natural (cool) wind and hot wind — easily changed with the built-in switch. Mounting: supplied with an adjustable, rotatable bracket for precise direction of airflow. Compatibility: designed for use with 12 V and 24 V vehicle systems (cars, trucks, vans, RVs). Functions: works as a heater for warming the cabin and as a fan for ventilation; effective for defogging and defrosting windshields. How it solves common problems Fogged or iced windshields: switch to hot wind to remove frost and condensation quickly and safely. Cold cabin without running the main heater: use the device as a supplemental heater to warm driver and front-seat passenger areas. Overheating or electrical risk minimization: integrated safety features help prevent device or vehicle damage during use. Practical use scenarios Winter morning commute: mount and aim at the windshield to defrost and defog before driving. Camping or road trips: use inside a vehicle to provide quick spot heating or extra ventilation without relying on cabin HVAC. Trucking and commercial vehicles: compatible with 12 V and 24 V systems for defogging windshields in cars and larger vehicles. What to expect in use Simple plug-and-play operation with a two-position switch for immediate hot or natural airflow. Durable construction meant to withstand repeated use and in-vehicle conditions. Adjustable mounting for targeted airflow that improves windshield visibility and passenger comfort. Note: Designed specifically for automotive use with 12 V/24 V power systems.
