Portable Waist Fan – 8000mAh TEC Cooling, 100-Speed, Solar-Assisted | Traverseon

Under-Shirt Airflow and TEC Contact Cooling, More Comfort on Hot Workdays

This TEC cooling waist fan combines upward under-shirt airflow with direct-contact cooling. Worn at the waist, it delivers airflow up to 6.05 m/s (19.8 ft/s) inside your clothing to help move trapped heat away from the chest and back while reducing the sticky feel of sweat-soaked fabric. During work breaks or outdoor activities, place the TEC cooling plate against your neck, arm or face for more direct localized cooling, with the plate surface reaching as low as approximately 16°C (60.8°F). Its 100-speed control lets you fine-tune airflow for changing weather, activity levels and runtime needs, with motor speeds reaching up to 14,400 RPM.

Under test conditions of approximately 25°C (77°F), the 8000mAh battery delivers more than 36 hours at the lowest setting and over 7 hours at maximum airflow, providing longer personal cooling for outdoor work, camping, fishing, gardening, theme parks and summer travel. The fan can be worn at the waist or neck, held for direct TEC cooling, or placed on a desk, while solar-assisted top-up and an emergency LED light add versatility outdoors. It measures 4.8 × 9 × 9.2 cm (1.9 × 3.5 × 3.6 in), weighs approximately 350 g (12.3 oz), and is available in Deep Space Gray and Vibrant Orange.

• Upward Under-Shirt Airflow, Hands-Free Comfort for Hot Workdays
  Clip the fan at your waist to direct airflow upward inside your clothing, helping move trapped heat away from your chest, back and waist while reducing the sticky feel of sweat-soaked fabric. It keeps both hands free during construction work, gardening, outdoor activities and long summer walks.
• TEC Contact Cooling Down to Approximately 16°C, Direct Relief During Breaks
  The TEC cooling plate can reach a surface temperature as low as approximately 16°C (60.8°F). Hold it against your neck, arm or face for more direct localized cooling after outdoor work, hiking or gardening, especially when ordinary airflow alone does not provide enough immediate relief.
• 100-Speed Adjustable Airflow, Fine-Tuned Comfort for Changing Heat
  Adjust the airflow from gentle everyday circulation to stronger under-shirt ventilation according to the weather, activity level and desired runtime. The motor reaches up to 14,400 RPM with airflow up to 6.05 m/s (19.8 ft/s), delivering more noticeable air movement during hot outdoor use.
• 8000mAh Verified Runtime, Longer Cooling for Work and Outdoor Days
  Under test conditions of approximately 25°C (77°F), the battery delivers more than 36 hours at the lowest setting and over 7 hours at maximum airflow. It helps reduce mid-day charging during outdoor work, theme park visits, fishing trips and extended camping activities.
• Solar-Assisted Top-Up, Extra Power Support Away from Outlets
  The built-in monocrystalline solar panel provides supplemental charging in sunny campsites, fishing spots, worksites and gardens. Under ideal strong-light conditions, approximately 24 cumulative hours of sunlight can add about 1000mAh of power and provide more than half an hour of additional runtime.
• Waist, Neck, Handheld and Desk Use, Flexible Cooling from Work to Rest
  Wear it at the waist for hands-free under-shirt airflow, hang it around your neck while moving, hold the TEC plate against localized hot spots, or place it on a desk when you stop to rest. One device adapts to work, commuting, camping and indoor use.
• Emergency LED Light, Added Visibility for Nighttime Tasks
  The built-in LED light provides convenient illumination when locating gear at camp, fishing after dark, walking at night, handling quick repairs or dealing with a power outage. It adds useful nighttime functionality without requiring a separate small flashlight.
• Digital Display, More Intuitive Viewing and Control
  The digital interface presents operating information in one clear location, making everyday viewing and adjustment more straightforward. It helps users manage the fan more confidently while switching airflow levels or planning longer periods outdoors.
• ABS + PC Housing, Everyday Durability for Carrying and Gifting
  Built with ABS + PC materials, the housing is designed for everyday durability and portable use, helping it handle the normal bumps and movement of outdoor work, camping trips and daily carry. With under-shirt airflow, TEC cooling, solar-assisted top-up and an emergency light in one device, it is practical for personal use and makes a useful warm-weather gift for family, friends and outdoor users.

• Warm Tips
  1. TEC Cooling Temperature: The approximately 16°C (60.8°F) specification refers to the minimum surface temperature of the TEC cooling plate for localized contact cooling on areas such as the neck, arm or face. It is not the air outlet temperature.
  2. Solar-Assisted Top-Up: The monocrystalline solar panel provides supplemental outdoor charging, while USB-C remains the primary charging method. Under ideal strong-light conditions, approximately 24 cumulative hours of sunlight may add about 1000mAh and provide more than half an hour of additional runtime.
  3. Runtime Performance: Actual runtime depends on the selected airflow level and enabled functions. Higher airflow settings and TEC cooling use consume battery power more quickly.
  4. Charging and Storage: Use a compatible 5V⎓2A power source for charging. When storing the fan for an extended period, keep it in a cool, dry place and recharge the battery periodically.
  5. Cleaning and Maintenance: Wipe the housing and TEC cooling plate with a soft, dry cloth after use. Keep the air inlet and outlet clear to reduce the buildup of dust, sweat and debris.
  6. Water Exposure: Avoid exposing the fan to rain, immersion or prolonged humid conditions. Keep it away from water and make sure the charging port remains dry during charging.
