A soft cooler with high freedom that allows you to move it around in rentals and new construction rooms where air conditioning cannot be installed, kitchens, dressing rooms, living rooms, garages and warehouses, as well as in a camper or campsite. Keep coolers and air conditioners where you can't place them anywhere. Recommended for simple movable coolers • (No Drainage Required, Effortlessly) The JYWINA portable air conditioner is equipped with an advanced non-drainage system that uses a high quality water pump to quickly pump the drainage water generated when cooling the air from the tank, and then efficiently evaporate it with heat exchanger and discharge it outside with heat exhaust, so there is no need to drain water frequently. Note 1: Please tightly seal the lid of the drain when using. When you open the lid it will lead to continuous drainage. Note 2: Only cold air operation does not require drainage for a long period of time. Evaporation will not be captured when dehumidified or indoor humidity is very high, so we recommend attaching a hose and continuous drainage. Please use a non-drain type that does not require drainage. Not only does it require drainage, but it also increases the cooling effect by the evaporative heat at the time of evaporation, so the power consumption will naturally decrease slightly. It is the best choice for a way to cool the room with air conditioning installed in a tight air conditioner
