Product name: Portable Multifunction Car Heater (Windshield De-icer and Defogger) Key benefits Quickly clears frost, fog and moisture from the windshield so you can drive safely in cold or humid conditions. Heats up in about 1 minute, so you get usable heat fast — even when stationary in traffic — without needing to keep the engine running. Compact and portable design: easy to move between vehicles or to store when not in use. How it solves common problems Winter mornings: melts frost and ice on the windshield before you drive, saving time and improving visibility. Condensation and fogging: clears interior fog and prevents re-accumulation for safer visibility in rain and cold weather. Traffic or breakdowns in cold weather: provides immediate local heat to the windshield/cabin area while you wait. Standout features Fast heat-up: efficient thermal design delivers warm air in approximately 1 minute. High-temperature double air outlet: twin vents produce concentrated warm air, reaching surface temperatures around 80–100 °C for effective de-icing and defogging. Durable metal construction: made from strong metal material that resists deformation and wear for extended service life. Portable and multifunctional: designed for windshield defrosting/defogging and supplemental cabin heating as needed. Performance and compatibility Power source: connects directly to the vehicle battery. Follow the correct polarity: red wire to positive (+), black wire to negative (−). Wiring requirement: use 4–6 mm^2 pure copper wire for the battery connection to ensure safe and reliable power delivery. Note: designed for portable in-vehicle use; install and connect only as described and observe appropriate safety precautions when connecting to the battery. Installation overview (simple) Position the heater on a stable surface directing the air toward the windshield or desired area. Connect red wire to the battery positive terminal and black wire to the negative terminal. Use 4–6 mm^2 pure copper wire for connections. Confirm secure, correct polarity before powering on. Practical use scenarios Morning commute: remove frost and ice quickly so you can leave sooner with clear visibility. Heavy rain or rapid temperature change: clear interior windshield fog to restore driving visibility. Cold traffic delays: provide immediate localized heat to the windshield and front cabin area without running the engine. Materials and durability Constructed with robust metal components to resist deformation and wear under repeated use. Designed for repeated heating cycles and portable handling. Safety and user notes Observe correct polarity when connecting to the battery (red to +, black to −). Use recommended wire gauge (4–6 mm^2) and secure connections to prevent overheating or voltage loss. Place the heater on a stable surface and avoid direct contact with combustible materials when operating. Follow local vehicle and electrical safety guidelines during installation and use.
