How To Control The Temperature Of The Heating Pad

Before use, connect the heating pad correctly to the power supply, usually through a cigarette lighter head or socket. 
Turn on the heating pad and select the appropriate temperature range. Most heating pads have adjustable temperatures in three levels: low, medium, and high, with a temperature range generally between 30 and 60 degrees Celsius. 
Adjust the temperature and time of the heating pad as needed. Some advanced models may allow for specific temperature and heating time settings. 
During use, be careful not to let the heating pad work continuously for a long time to avoid overheating or damage. It is recommended to turn off the power and unplug the plug after each use.
When using, it is important to avoid direct contact between the heating pad and the skin to prevent burns. Meanwhile, avoid using heating pads on damp or flammable objects. 
When not using heating pads, they should be stored in a dry and cool place, avoiding direct sunlight or humid environments.
