1. This is the current intensity output by the charger; 500ma chargers have become increasingly rare. Now the output current is more than 1A, and many chargers have reached 2A.
2. Ambient temperature.
3. The high temperature of the charger also has a great relationship with the switch tube of the charger. If the switch tube specification is not high, the current will pass through and the heat will be more.
4. The size of the charger is also a problem. In order to make it convenient for consumers to carry around when they go out, chargers often seek to make their products smaller. The smaller the volume, the worse the heat dissipation performance, and the higher the requirements for electronic components. Take the capacitor for example, while keeping the capacity unchanged, the volume of high-voltage capacitor is getting smaller and smaller, and it is also better in terms of withstand voltage and temperature. If the withstand voltage is not enough, it will break down the capacitor, and if the temperature resistance is not enough, it will burst the capacitor.
5. Counterfeit products are more likely to cause abnormal temperature rise. The stability of the output voltage of the copycat charger itself is not as good as that of the original charger, which will cause problems such as slow charging and serious heating of the charger.
