How To Choose A Mobile Phone Charger?

When choosing a compatible mobile phone charger, you should also pay attention to the brand. It should be a product produced by a regular manufacturer. Because although some of the principles of the charger are introduced above, it is very difficult to identify it in practice. Even for professionals, it is difficult to accurately judge the performance and quality of the charger from the appearance of the charger without opening the charger or using a test instrument. Although the prices of some well-known brands are slightly higher, they are more formal and scientific from the circuit design to the selection of components, so the charging effect is also more ideal. For non-original chargers, it depends on the fineness of the mold, whether the mobile phone can be plugged in and out at one time, and whether the resistance is uniform and the tightness is moderate. For some chargers that directly charge the battery, like the travel charger mentioned above, it depends on the reasonableness of its circuit design.
Generally speaking, only chargers with the "CQC" certification mark are safe. Therefore, you should try to buy products with "CQC" or other certification marks. Secondly, buy a charger that is compatible with your mobile phone. Mobile phone chargers generally have two charging functions: one is to charge with the machine (the charger charges the battery through the electrical connector and the mobile phone), and the other is to charge the battery through the charging stand. Before purchasing, you should be clear about the type, capacity, and nominal voltage of the battery you are using so that you can choose a charger that is suitable for it.
Standard charger products are marked with technical parameters such as the range of use, output voltage, and output current. If conditions permit, you can use a multimeter to test the output no-load voltage and output short-circuit current of the charger when purchasing to determine whether the actual data is consistent with the marked technical parameters.
Chargers of different brands can be mixed and used. As long as the interface is the same and the output voltage and current are consistent, they can be used universally. The country has already issued a document to unify the standards for mobile phone chargers in 2010. In theory, there is no effect of mixing, but ordinary people have little idea whether the output current is the same, and it is easy to make mistakes. It is recommended to use the original charger, but to resolutely avoid using counterfeit and inferior chargers.
