Product compatibility Designed for MercedesBenz EQV Van (2020–2025). Operates from a 12V, 150W cigarette lighter socket. Before , verify your vehicle's cigarette lighter provides 12V and can handle 150W. Key functions and benefits 2in1 heating and cooling: switch between heating mode to add warmth and defrost the windshield, or fan mode to improve airflow in warmer weather. Fast heating and defrosting: rapidwarming design produces airflow that quickly transitions to warm air, helping clear frost and reduce fog so you spend less time waiting for the cabin to warm. airflow for even warming: volume circulating convection airflow distributes heat more evenly through the cabin rather than creating a single hot spot. Portable, plugandplay operation: plugs into the vehicle cigarette lighter for immediate use without permanent installation. Build quality and materials Alloy heating wire provides steady heat output, resists aging, and sustains performance under repeated use. External components are engineered to resist deformation and cracking at higher temperatures, supporting reliable use across seasons. Practical and durable for regular invehicle use. Performance highlights 12V, 150W power rating suitable for quick supplemental heat and effective defrosting. Dualmode control for simple switching between heat and fan. Designed to reduce coldstart discomfort and improve visibility by clearing windshield fog and frost. Typical use scenarios 1. Cold mornings: plug in to quickly defrost the windshield and warm the cabin before driving, reducing wait time and improving visibility. 2.
