Sturdy and secure design Robust construction improves airflow coverage by over 40 percent, delivering reliable heating even in challenging environments. The heat resistant density mesh enhances safety and durability for long term use. Optimized heating efficiency Vent design speeds up cabin warming, delivering heating twice as fast as typical portable units. Effectively removes frost and fog in under 90 seconds while providing consistent 360 degree heat coverage throughout the cabin. Targeted heating control Rotating heat outlet enables 360 degree directional airflow adjustments, allowing you to tailor heat to specific seat zones for precise comfort. Safety mechanisms Four layer insulated copper wires reduce heat exposure and enhance durability. Low heat mode keeps surface temperature below 45 C for added safety. Anti battery drain design helps protect your vehicle's electrical system. Overheat fuse safety and a stable power load system provide reliable protection during use.
