ecoCalm Solar Powered Fan with Battery & Adjustable Thermostat – 6-inch Exhaust Fan

Discover the ecoCalm Solar Powered Fan with Battery and Adjustable Thermostat, a smart, weather-ready solution designed for coops, greenhouses, sheds, and other outdoor spaces. It blends solar energy with practical automation to help you move air where it matters most, without relying on cords or constant maintenance.

Smart, battery-backed airflow

This exhaust fan features a double-sided solar panel paired with a 4400mAh rechargeable battery. The battery can provide up to 8 hours of ventilation after a full sun charge, helping you keep air moving during the night or on cloudy days. The system automatically switches power sources based on sun conditions, so you get airflow when conditions allow.

• Solar air conditioner with battery adds night-time circulation and daytime support.
• Intelligent power switching optimizes energy use as sunlight changes.

Hands-free comfort with adjustable temperature control

The battery box includes an intelligent temperature control system, letting you set the ambient threshold at which the fan powers on and off. This helps maintain a comfortable environment without constant monitoring.

• Automatic on/off based on your preferred temperature range.
• Fine-tuned airflow to match the space you’re cooling.

Efficient, bidirectional solar energy

The 8W transparent rear (bifacial) panel generates power from both sides, delivering up to 20W under ideal sun. This boosts charging efficiency and supports sustained fan performance, though performance can vary with cloudy weather.

• Bidirectional panel boosts energy capture for better run-time.
• Efficiency gains depend on sun exposure; cloudy days may reduce output.

Rugged for outdoor use

Designed for harsh environments, the fan blades carry an IP44 waterproof rating, and the 14.8 ft cable with a waterproof plug allows flexible placement. This setup helps protect internal electronics while delivering reliable airflow in outdoor spaces.

• Weatherproof, safe for greenhouses, chicken coops, and sheds.
• Long, weather-resistant cable for versatile installation.

Strong airflow for versatile spaces

Engineered blades and a robust motor deliver 120 CFM, suitable for spaces up to 320 ft³. This makes it a practical choice for greenhouses, animal housing, or larger sheds where ventilation matters for air quality and comfort.

• High airflow supports efficient cross-ventilation.
• Ideal for small to medium semi-outdoor spaces.

Note: Sunlight availability directly influences performance. For best results, position the unit where it receives consistent sun exposure and use the thermostat to tailor operation to your space. The combination of a solar panel, battery, and smart controls offers a flexible, energy-aware cooling option without guarantees of specific outcomes.
