Why is the iPhone Charger Hot? – iPhone Charger Wholesaler

Why is the iPhone charger hot?

When the phone is charging, the phone charger is hot, which is related to the current intensity of the phone charger and the ambient temperature. With the popularity of smart phones, the 500mA phone charger can no longer meet the user’s demand for charging speed, so we see that the current common phone charger current is above 1A, and many phone charger currents have reached 2A.

In addition to the increase in current, the size of the phone charger is also a problem. For ease of carrying, people tend to prefer smaller chargers. However, the volume becomes smaller, the heat dissipation performance is deteriorated, and the requirements for the production of electronic components are also higher.

In addition, the high temperature of the phone charger has a great relationship with the switch tube of the phone charger. If the specification of the switch tube is not good, the heat will be more. The output voltage of the inferior phone charger itself is not as stable as the original phone charger, which causes problems such as slow charging and serious heat generation of the charger.

In appearance, the inferior phone charger and the original phone charger are no different, but after the disassembly, the difference is obvious, the safety of the original phone charger is significantly higher. In design, the original phone charger has circuit protection, which can improve the heat dissipation and insulation of the charger. These are important methods to improve the safety of the charger, but the inferior phone charger is basically not.

At the same time, in addition to the phone charger itself, the original data cable and the inferior data cable are also very different. The original data cable uses about 20 copper core wires, which is safer. The inferior data cable basically has only 7 copper core wires. Its ability to pass current is only one third of the original data cable. So when you find that your phone charger is hot, first check if you are using the original phone charger. （related articles: How to avoid USB phone charger fever）
