Lexical Rechargeable AC/DC Evaporative Air Cooler with 9000mah Battery

This rechargeable evaporative air cooler provides high-volume cooling and air circulation for living rooms, offices, bedrooms, and outdoor areas during power outages. Equipped with a built-in 12V rechargeable battery and dual AC/DC power support, this mobile air cooler runs on main electricity or battery power to keep your space comfortable. The unit features a large 30-litre water tank capacity and produces up to 3600 m³/h airflow for wide-area coverage. Powered by an energy-efficient 50W motor, it incorporates wide-angle oscillation louvers, multi-speed fan controls, and smooth-rolling castor wheels for easy mobility around the house.  

SAFETY NOTE

1. Always unplug the air cooler from the main electrical outlet before filling or cleaning the 30-litre water tank.  
2. Do not tilt, lean, or move the unit while the water tank is full to avoid water spilling into internal electrical circuits.  
3. Charge the internal 12V battery fully before long power outages or extended storage to preserve battery life.  
4. Keep the air intake vents and louver outlet free from obstacles to ensure proper ventilation.  

GUIDE TO PROPER USAGE

1. Position the air cooler on a level surface in front of an open window or door for cross-ventilation.  
2. Fill clean tap water (or cold water with ice packs) directly into the water reservoir inlet.  
3. Plug the unit into an AC wall socket to power the unit while simultaneously charging the 12V battery, or turn on DC mode for cordless operation.  
4. Switch on the fan and select your desired speed level and louver swing function.  
5. Drain unused water from the bottom drain outlet if the unit will not be used for several days.
