Only the chargers with the CQC certification mark are safe
Jul 31, 2021| Generally speaking, only the chargers with the "CQC" certification mark are safe. Therefore, try to buy products with "CQC" or other certification marks. Next, choose a charger that is compatible with your mobile phone.
Mobile phone chargers generally have two charging functions: one is charging with the machine (the charger cooperates with the mobile phone to charge the battery through the electrical connector), and the other is charging the battery through the charging stand. Before purchasing, you should know the type, capacity, and nominal voltage of the battery you are using, so that you can choose a suitable charger.
The standard charger products are marked with technical parameters such as the range of use, output voltage and output current. If possible, use a multimeter to test the output no-load voltage value and output short-circuit current value of the charger when purchasing to determine whether the actual data is consistent with the marked technical parameters.
