Short charging time
Output parameters refer to the electrical parameters that the charger can provide when charging the device, generally voltage and current; If the output of the mobile phone charger is: 5V 1A, it is said that this charger can provide a voltage of 5V and a current of 1A. The difference between fast charge and full charge is mainly to see the output current, the larger the current, the faster the charging speed, the shorter the charging time, of course, the battery needs to be charged within the range.
1. Record the charging time of the mobile phone through actual recording. According to the experience of use, if you start charging when the power is 0~10%, after half an hour or so, the phone power can be basically restored to about 60%, and the device can be basically judged to be fast charged.
2. The DC input voltage of the charging interface is 5V±5%, and the maximum absorbed current is 1800mA. As long as the output of the adapter breaks through this condition, it is fast charging.
Third, download a charging detection software, you can see the device's charging temperature, voltage and whether there is a fast charge.
