Recently, mini cooling devices such as handheld fans with cold mongs have become a popular choice because of their superiority and convenience in use. When choosing to use a handheld fan with a refrigerator, you need to pay attention to some features to be able to use it effectively, avoiding potential risks.
Can't cool like air conditioners
Handheld fans integrated with cold clams can create a local cool feeling at the point of contact and cannot reduce the temperature of the surrounding environment like air conditioners. The cooling level typically ranges from 5 to 10°C at the contact surface, and the cooling effect can decrease rapidly if not maintained by a stable power source or used in outdoor space.
Not used continuously for a long time
Many users believe that this device can operate continuously like a traditional power fan. However, due to the structure of using cold clams and small fans, the device is susceptible to overheating if used continuously for a long time, especially during peak hot weather like summer. Continuous use of the product for more than 30 minutes can reduce the life of the cold moth or cause internal damage to the components.
Assessing technical specifications
Evaluating technical specifications will help choose suitable products as well as durability when used. Technical specifications include chip cau truc, transmission area, wind power capability and power source. Therefore, carefully consider the parameters according to the desired goals of the user.
Causes skin irritation
Some fan lines use cold metal pieces to apply directly to the skin to create an immediate cool feeling. However, prolonged exposure to cold metal surfaces such as the neck, neck, etc. can easily cause irritation, cold burns, or skin numbness. This should be noted when using a cold clam handle to protect the skin.
