Yesterday I shared how to choose usb charger in terms of sense of weight and charger pins. 

Today I will show you how to choose charger through usb interface and surface heat.

1. USB interface

Now a lot of usb chargers and charging lines are separate. Charging cable can be replaced for charging different mobile phones. If you buy this kind of charger, please pay attention to the usb charger interface and charging cable whether they are able to fully interface. Too lose or too tight interface are not good. Too lose interface may allow mobile phones to receive unstable current, but also may form a strong instantaneous current. Too tight interface is easy to break. In addition, the choice of charging line for mobile phone interface can also refer to this standard.


2. Surface heat

In the process of mobile phone charging, the internal transformer of usb charger will produce a certain amount of heat. In general, the heat temperature will not exceed 30℃. The better the quality of the transformer, the less of the heat generated when charging, the more secure the mobile phone. Touch the usb charger when charging, if it is a slight fever but not hot, it is normally acceptable. If it is very hot, we should pay special attention to it and it is better not to use it.
