We are all three-step mobile phones. We always like to pick up the mobile phone to have a look whether there is anything or not, which indirectly leads to the rapid power loss of the mobile phone, and we almost have to charge it once or even several times a day.
When charging, we will find that the mobile phone charger is hot. Some mobile phone chargers are normal, but some are not. Therefore, we need to know what is normal, then we dare to use them safely.
Firstly, the scalding degree of the charger is mainly related to the current intensity output by the charger; Now we generally use 2A fast charging. The difference between the temperature and no operation is about 5 °. If you use a constant voltage flash charging charger, the degree of scalding must be more serious than 2A fast charging.
Secondly, the high temperature of the charger also has a great relationship with the components of the charger. If the specification of the switch tube used by the charger is not high, the current will pass through and the heat will be greater.
In addition, the volume of the charger is also a problem. In order to be convenient to carry, the charger will pursue to reduce the volume of the product, so the heat dissipation performance will become worse, and the higher the requirements for electronic components. At present, the solution of large companies is to add heat dissipation patches on the heat source.
Of course, fake products are more likely to cause abnormal temperature rise; The stability of the output voltage of the fake charger itself is not as good as that of the original charger, which will cause serious heating problem of the charger, so we should try to use the original mobile phone charger.
So what problems should we avoid when using the charger?
When using the charger, we should avoid direct sunlight and keep away from the heat source. The shell and bottom of the charger should not be covered with articles and should be well ventilated.
When charging with the charger, the elderly and children should be prevented from contacting the charger.
When the charger is unplugged, the metal contact is charged. It is strictly prohibited to touch it by hand or contact the two contacts with conductive objects.
When charging, if the charger shell is hot (about 50 ℃) or smells and smokes, unplug the power immediately, stop charging and do not use it again.
