China ​Rechargeable Air Cooler Factory - Compact Design for Camping, Office & Home

Koyer is a professional China rechargeable air cooler manufacturer, and we have our own factory to do customized design. Powered by a rechargeable battery and boasting a lightweight design, our rechargeable air cooler breaks free from the constraints of fixed power supplies that limit traditional air coolers, making it ideal for a wide range of mobile scenarios.

Equipped with a large-capacity rechargeable lithium battery, it delivers 14–16 hours of continuous operation on a full charge without the need for an external power source. It is perfect for spot cooling in home living rooms and bedrooms, and equally suited for off-grid environments such as outdoor camping, picnics, RV trips, temporary construction site rest areas, and even as a vehicle-mounted cooling solution.

Product Usage

Koyer rechargeable air cooler supports multiple charging methods, including solar panels, car chargers, and household sockets. In outdoor settings, it can achieve "energy self-sufficiency" via solar power, aligning with low-carbon travel concepts. Featuring 9–12 adjustable wind speed and cooling modes, users can tailor the device to their specific needs: in low-speed mode, battery life extends to over 16 hours, catering to varying usage durations. With a noise level of just 60dB in low-speed mode, it won’t disrupt nighttime sleep, office work, or outdoor camping rest—offering a far more pleasant user experience than the high-noise operation of traditional air coolers.

Adopting 12V/24V low-voltage battery power supply, it eliminates the electric shock risk associated with high-voltage mains electricity, making it particularly safe for families with children or the elderly, as well as multi-person outdoor gatherings. The battery is integrated with overcharge, over-discharge, and short-circuit protection mechanisms, ensuring safe and stable performance during both charging and operation.
