Product: 12V 150W Car Heater for MercedesBenz SClass Maybach (1951–2025) Key benefits — why you need this Fast windshield defrost and defogging: quickly clears frost and fog so you can drive safely without long wait times. Yearround comfort: two modes (heater and fan) deliver cabin warmth in cold weather and improved airflow in warm weather. Simple, reliable operation: plug into the 12V cigarette lighter and switch modes—no complex installation. What it does and how it stands out 2in1 heating and cooling: a single portable unit switches between heater mode (warm air for defrosting and cabin comfort) and fan mode (cool air circulation to improve ventilation). airflow and fast heating: designed to start airflow immediately and transition to warm air quickly, supporting even cabin warming and rapid windshield defrosting. Durable construction: alloy heating wire provides steady, longlasting heat, resists aging under load, and is built to handle pressure. External parts are made to resist deformation or cracking at elevated temperatures, making the unit suitable for seasonal use. Specifications and compatibility Rated voltage and power: 12V, 150W. Before , verify that your vehicle's cigarette lighter socket supports this voltage and power. Vehicle fit: specifically for MercedesBenz SClass Maybach models (1951–2025). Design: portable, compact unit that plugs into the cigarette lighter for easy placement and storage. Performance and materials Heating element: alloy heating wire for consistent warmth and extended service life. Airflow: volume convection circulation for faster, more uniform cabin warming and effective defrosting. Durability: outer components engineered to resist heatrelated deformation and cracking. Practical use scenarios Cold morning commute: plug in before you start driving to quickly defrost the windshield and warm the cabin so you can leave sooner and drive safely. Winter parking: use to remove fog and ice buildup while you prepare the vehicle, reducing visibility hazards. Summer traffic or poor ventilation: switch to fan mode to boost airflow and reduce stuffiness without running full car HVAC. Important note Check your vehicle's cigarette lighter voltage and power capability before to ensure compatibility with the 12V 150W rating.
