Abstract

The invention discloses a charging method and a charger. The method comprises the steps as follows: the charger outputs first voltage to a mobile terminal when a preset condition is met, so that the mobile terminal is in a short-circuit detection state; the preset condition is that the charger and a USB interface of the mobile terminal are located in a connected state; first output current at thefirst voltage is acquired; and when the first output current is smaller than a first preset value, the charger outputs target voltage to the mobile terminal, so that the mobile terminal is in a charged state. According to the charging method and the charger, the USB interface of the mobile terminal can be prevented from being burnt out.

Description

technical field [0001] The invention relates to the communication field, in particular to a charging method and a charger. Background technique [0002] The interface types adopted by the mobile terminal generally include two types of USB interfaces, one is a Micro USB interface, and the other is a USB Type C interface. [0003] Along with the increase of mobile terminal use time, the USB interface of mobile terminal can inevitably have the situation of foreign matter, as fine dust etc. When the mobile terminal is connected to an external charger through the USB interface for charging, these foreign objects may cause the USB interface of the mobile terminal to form a short circuit. This short circuit will cause the current at the USB interface to rise, and there is a possibility of burning the USB interface. In severe cases, the entire mobile terminal may be scrapped. [0004] Therefore, in any case, when charging the mobile terminal by the USB interface, it is necessary t...
