This bed cooler will help you sleep like a baby on hot summer nights. Maximum storage of 200 kg: the mattress is made of a superconducting blanket body made of special PVC/PA material, the edge is pressed by high temperature hot pressing process and shaped as a whole, can support 200 kg. Double layer water lock. So you can enjoy the maximum comfort for a good night's sleep. VISIBLE WATER TANK AND TYPE C INTERFACE: 2 litre large capacity water storage tank. By adding water once, cooling can be continued for 10 hours. The water volume is clearly visible and the remaining water volume can be checked in time. The Type-C interface easily meets your different usage requirements. 3 WIND SPEED SETTINGS: Touch the button at the top of the machine and select one of three wind speeds.
