In fact, it is normal for any portable charger to heat up. The charger converts the AC power from the outlet to the DC power for the phone and generates heat in the process.

Thermal chargers shouldn’t be too much of a problem if it can be controlled Screenshots |
To perform AC/DC conversion, chargers use electronic components called transformers. Transformers generate heat due to frequent conduction, eddy currents, and other losses, which are a side effect of the way transformers work. Generally speaking, the more current a transformer provides, the more heat it generates.
Under normal conditions, the phone charger might feel a little warm to the touch, which is okay because it works as designed. But if it’s suddenly unusually hot, that could be a problem.
What if it’s too hot?
Users may find it uncomfortable to hold or touch, the most obvious signs of a problem. This can be caused by a problem inside the charger itself or a connection problem between the charger and the outlet. The high-quality genuine charger has a protection circuit, which will automatically cut off the charging if there is a problem. But this circuit could be faulty, or a poor or counterfeit charger could be used.
If the charger isn’t overheating, unplug it from the outlet and look for any visible signs of dirt or blockage on the prongs that plug into the wall outlet. Also, check to make sure the charging port on the phone is clean, and check the USB port on the charger itself (if applicable) for signs of dirt or lint.

fire risk
If you see any of these warning signs on the charger or charging cable, stop using the charger or cable immediately and replace it. If the charger fails, the user can try to contact the manufacturer’s customer support for a replacement.
- Melt marks can be seen on the charger plastic kit or charging cable
- The charger has an odor, such as smoke or molten plastic.
- Burns (black or brown) on the charger, cable, or socket plugged into the charger.

Watch for abnormal signs when charging Screenshots |
Use a high-quality charger from a brand
As mentioned above, some of the reasons a charger can get hot while charging is due to poor quality or counterfeit components. These parts do not meet safety standards and regulations.
Currently, online vendors such as Amazon and AliExpress sell many counterfeit and potentially malicious electronic products. This includes wireless, wired and USB chargers. If you purchased a damaged charger, ask for a refund and consider purchasing a new charger directly from the phone manufacturer, such as Apple or Samsung.
