Key Features

• Humidity-Boosting Mist Technology: Integrated evaporative misting increases air moisture and rapidly lowers the ambient temperature around you — ideal for dry, air-conditioned rooms or hot outdoor environments.
• 2-Speed Airflow + Dual Atomization Modes: Choose from two fan speeds and two misting settings (continuous or intermittent spray) to customize your personal comfort level throughout the day.
• 20° Vertical Tilt Adjustment: Direct airflow exactly where you need it — perfect for desk use, nightstand placement, or tabletop cooling.
• 500ml Large Water Tank: The generously sized reservoir means fewer refills and longer continuous misting sessions — great for extended work sessions, picnics, camping, and meetings.
• USB Rechargeable & Cordless: Powered by a built-in 3000mAh rechargeable battery (approx. 3 hours runtime at max settings) or directly via USB plug-in. Compact and light enough to carry in a backpack or bag.

Frequently Asked Questions

Q: How long does the 500ml portable evaporative air cooler run on battery?

A: At maximum fan speed and full continuous spray, the built-in 3000mAh rechargeable battery provides approximately 3 hours of runtime. At lower settings, battery life will be noticeably longer.

Q: Can I use this air cooler while it's charging via USB?

A: Yes! The cooler supports dual power modes — it can run directly from a USB power source (power bank, laptop, wall adapter) while also being used, so you can enjoy continuous cooling without worrying about battery level.

Q: Is this evaporative cooler suitable for outdoor use like camping?

A: Absolutely. Its compact, lightweight design and cordless operation make it highly portable for outdoor activities such as camping, picnics, car travel, and commutes. Just fill the 500ml tank and go.

Q: What is the difference between the two misting/atomization modes?

A: The first misting mode delivers continuous spray for maximum cooling, while the second mode offers intermittent spray to conserve water and extend tank life — great when you want a lighter, more energy-efficient mist.
