• 21V External Rechargeable Lithium Power, Use Anywhere
  Powered by an external 21V rechargeable lithium source, it starts up as soon as it’s connected. Whether in the car, tent, or outdoor rest areas, it delivers steady warm air or natural airflow.
• 3-Second Instant Heat, Warm Up Immediately
  The PTC heating element rises to temperature the moment it’s powered, producing warm air in about 3 seconds. Perfect for getting warm right after getting in the car, waking up at a campsite, or heading out in cold, rainy, or snowy weather.
• Hot & Natural Air Modes, Comfort for All Seasons
  Natural airflow helps reduce stuffiness and improve air circulation, while the heating mode delivers stable warmth for winter and cold environments. One device serves you all year round.
• 90° Tilt Adjustment, Direct Heat Where You Need It
  The unit tilts up to 90°, allowing the airflow to angle downward toward your feet, legs, or any specific area that needs warming. Heat is focused exactly where it’s needed for better efficiency.
• Quiet Operation, Comfort Without Disruption
  An optimized air channel and fan structure keep noise soft and unobtrusive. Ideal for sleeping, quiet commutes, reading, or working without disturbance.
• Dual USB Output, Stay Warm While Charging Devices
  Equipped with 5V / 2A USB output, it powers phones, GPS units, or small devices without occupying your car’s socket. Even in cold weather when batteries drain faster, you can warm up and recharge at the same time.
• 3-Minute Defrost & Demist, Clear Visibility Fast
  Warm airflow directed at the windshield raises the surface temperature, melting frost and evaporating condensation in about 3 minutes. Get clearer visibility quickly in snowy or rainy conditions.
