Lamp charging, you may use the charger, the charger is generally to charge the battery of the lamp, there is electricity he will produce the heating effect of the transformer, transformer heating, because its load power supply is really very large, its temperature will continue to rise, reach the limit temperature, it will overheat the transformer.
The hot shell may also have a slight temperature, his transformer is called a high-frequency transformer, that is, the switch is usually not, 50 Hertz alternating current, is the use of low-frequency transformers, high-frequency transformers are tens of thousands of Hertz, 20,000 Hertz between 50,000 Hertz, unless, he may have heat, may be the bridge pile may have this long these original heat, Those things if you say that the plug is hot it may be that there is poor contact between the jack and the plug bat of the power adapter, which will cause the common situation of interval heating, which may burn the plastic of the socket panel into black
Power cut. Table lamp charging process, heat is a normal phenomenon, but if the work for a long time, it will produce a hot feeling, at this time, you need to check the power of the charging head is not too high, the formation of the battery overrush phenomenon, resulting in short-term power is too high, causing the battery reaction, a long time will burn the battery, cause a fire, you need to quickly power off, and then placed in the air smooth place, To cool down.
The circuit board needs to be checked due to poor contact
After a long time, turn off the electricity and take a break.
The lamp is hot to charge, possibly because the charging time is too long, and the internal circuit is damaged
The heat is caused by poor contact, either the plug is faulty or the socket is faulty. Take the lamp to another outlet to try, if it is not hot, change the outlet; Change the plug if it's still hot.
