12V 150W Portable Car Heater for MercedesBenz SL‑Class (R232) 2022–2025 Key benefits Rapid defrost and demist: starts airflow immediately and transitions to warm air to clear frost and fog from the windshield faster than idling alone. Year‑round usefulness: two modes (heating and fan) let you add cabin warmth in cold weather or boost airflow in warm weather. Even, higher airflow heating: circulating convection airflow distributes heat more evenly through the cabin instead of a single hot spot. Built for longevity: alloy heating wire and heat‑resistant outer components reduce aging, withstand pressure and higher temperatures, and support long‑term use. Features Compatibility: designed for Mercedes‑Benz SL‑Class (R232) model years 2022–2025. Before , please check whether the voltage and power are compatible with your vehicle's cigarette lighter. Power and supply: 12 V, 150 W. Dual function: simple switch selects heating mode for defrost/warmth or fan mode for improved airflow. Performance: fast‑warming design with ‑volume airflow for quicker defrosting and more even cabin warming. Construction: alloy heating element for steady heat output; outer materials resist deformation and cracking under higher temperatures. Portable design: compact unit that connects to the vehicle 12V cigarette lighter for convenient placement and use. Typical use scenarios Winter morning start: plug in to clear windshield frost and reduce in‑car fog while you prepare to drive. Coldweather trips: shorten warm‑up time and make the cabin comfortable more quickly on short drives or long journeys. Warmseason airflow boost: use fan mode to increase ventilation or circulate air when you want extra airflow without using air conditioning. Important note Before and installation, verify that your vehicle's cigarette lighter socket can supply 12 V and the 150 W load to ensure correct operation and avoid electrical issues.
