How is it that the charger heats up?

April 27, 2023

Many of us have probably experienced a situation where our phone charger heats up. Some people panic, others think it's normal. So what's going on with the charger heating up? Below, follow Manufacturer YHY together to understand it!

It is normal for the charger to get hot when charging, but if it is hot, we should pay attention to whether there is a problem with the quality of the product. The original charger does not rule out possible faults. In addition, when charging, pay attention to whether the power of the charger is matched with the mobile phone phase.

In addition, if the charger is not placed in a ventilated place to dissipate heat, or the charging time is too long, the internal electronic components in standby for a long time, itself will be hot. Therefore, the charger plug will be very hot for a long time. Or your charger doesn't match your appliance.

The volume of the charger is also one of the key factors of heating, in order to be easy to carry, we often like the smaller size of the charger, the manufacturer's research and development direction is also towards small and fine to develop. However, the volume becomes smaller, the heat dissipation performance will become worse, the higher the requirements for electronic components. Take the capacitor, the high voltage capacitor in the case of maintaining the same capacity, the volume is getting smaller and smaller, and in the voltage and temperature is better, but not enough voltage will breakdown the capacitor, not enough temperature will explode the capacitor.

Again is with the popularity of smart phones, now the charger requirements are more and more high, functional machine era 500ma charger has been unable to meet the needs of users for charging speed, in front of the emergence of what we say fast charge, in fact, is the inevitable history, so we see the current of the common charger are above 2A. Such a charger is also very empty and easy to heat when charging.

The high temperature of the charger also has a great relationship with the switch tube of the charger. If the specification of the switch tube is not high, then the current passes through and the heat will be more.

Now you know how the charger heats up! Of course, in fact, these reasons caused by fever is in fact a normal phenomenon, but if the charger is really hot to the degree of hot or there is a bad smell, it must belong to the abnormal phenomenon, we should be vigilant.
