The following data are obtained from factory standard laboratories and real scenarios for Rechargeable Solar Air Cooler. There is no exaggeration or false marking. The test environment is a standard indoor environment with a temperature of 28℃ and humidity of 55%:
- Cooling performance test: After starting for 3 minutes, it quickly provides cold air, and within 10 minutes, the ambient temperature can drop by 6-10℃. A 25-40㎡ space can achieve uniform cooling throughout the area without local temperature differences, and the cooling efficiency is stable.
- Battery endurance test: With a fully charged lithium battery, it can run at low speed for 8 hours, medium speed for 5-6 hours, and high speed for 4 hours. The endurance time matches the official parameters; the mains power mode can operate continuously for 24 hours without interruption.
- Noise test: Low speed 45dB, medium speed 52dB, high speed 62dB. The entire operation is smooth without abnormal sounds, and the quiet performance is better than similar cooling devices of the same specification.
- Air circulation performance test: The maximum air volume can reach 3500m³/h, with a long range of air circulation and wide coverage. A 40㎡ space can achieve rapid air circulation.
- Charging time test: In the fast charging mode with mains power, it takes 6-8 hours to fully charge; in the solar charging mode, it takes 8-10 hours to fully charge. The charging is stable without overheating, and the battery conversion rate is high.
- Water tank endurance test: With a 40L full water load, it can operate stably for 10 hours under continuous cooling conditions, without leakage or seepage problems, and has excellent water storage performance.
- Safety performance test: The device automatically shuts down and cuts off power when the water level is low within 10 seconds; continuous 72-hour operation test shows no overheating or overload phenomena; the battery charge and discharge cycle is stable, without bulging or leakage risks.

To ensure the lifespan, safety and optimal cooling performance of the Rechargeable Solar Air Cooler, based on the product structure and electrical characteristics, we have compiled standardized usage guidelines that are suitable for global user habits:
- The device can only be used with room temperature clean water. It is prohibited to add fragrances, essential oils, or liquids other than ice water to avoid clogging the wetting screen, corroding the water tank, and affecting the equipment performance.
- Solar charging requires a 12V-24V compatible solar panel. It is prohibited to connect power supply devices with incompatible voltages to prevent overloading of the circuit and damage to the mechanism and battery.
- For the first use or after long-term storage before restarting, it is recommended to fill the water tank to the brim, let it stand for 5 minutes, and then start the device to ensure the normal operation of the water circulation system.
- During operation, it is prohibited to tilt, invert, or forcefully move the device to avoid water leakage from the water tank, loosening of internal wires, and triggering faults.
- When not using for a long time, it is necessary to drain the residual water from the water tank, dry the body, turn off the power, and store it to prevent the accumulation of water, bacteria growth, and corrosion of components.
- When cleaning the device, the power supply must be cut off first. Use a soft cloth to wipe the body. It is prohibited to directly wash the mechanism, touch panel, and charging interface with water.
- For children to use, the child lock function must be enabled, and accompanied by an adult. Children are prohibited from disassembling or touching the internal structure of the device privately.
- The ice crystal box can only be placed in the water tank after being frozen to assist in cooling. It is prohibited to directly expose it to sunlight or high-temperature baking to avoid damage or deformation of the ice crystal box.
A1: The device uses an evaporative cooling system. It is energy-efficient, portable, and has no external unit. It can quickly cool down, humidify and purify the air, making it suitable for daily comfortable cooling. Compared to a compressor air conditioner, it does not have a strong low-temperature cooling effect and is more suitable for all scenarios such as home, outdoor, and emergency for comfortable cooling.
