How to Choose the Right Charger for Your Phone?

The battery is indispensable in the use of mobile phones, and the service life of the battery is not only related to the performance of the battery, but also closely related to the battery charger of the mobile phone. The quality of mobile phone battery charger directly determines the length of battery life, so it is very important to choose a good quality charger. Here's how the charger manufacturer will give everyone tips on how to choose a suitable mobile phone battery charger:


Check the charge termination control of the mobile phone battery charger


Low-current phone battery chargers generally use time control. High-current fast-chargers are generally more intelligent. The greater the current provided by the charger is, and the more complicated the charge termination control method is, the higher the cost and price will be. For users, they should choose according to their actual situation. If the battery capacity used is not very high, or the charging speed is not particularly important, you can choose an ordinary phone battery charger; if it is necessary to choose a fast-charger with a higher price, it is best to learn more about the performance of phone battery chargers and batteries.


For example, if a charger that can provide a maximum charging current of 1000mA is used to charge a 600mAh Ni-MH battery, the battery needs to be specially designed for high-current charging, or to ensure that the charger can provide a smaller current option.


Check the charging speed of phone battery charger


Common phone battery chargers adopt a constant current charging method, and the charging speed is mainly related to the current provided by the charger. The greater the charging current is, the faster the charging speed will be. The charging time is not only related to the charging speed, but also depends on the battery capacity. It should be noted that the higher the charging current is, the higher the quality requirements for the internal system design of the charger and battery will be. In general, the higher the charging current is, the more heat may be caused during the charging process, and the greater the damage to the performance of the battery will be. Inferior chargers and batteries are prone to liquid leakage and other safety performance problems during high-current fast charging.


Check the charging efficiency of phone battery chargers


Not all of the energy input to the battery during charging is converted into the energy stored by the battery, and part of it is used for side reactions inside the battery and converted into heat during the charging process, so the charging efficiency is always less than 100%. When charging, the charging current should be controlled within a certain range. If the charging current is too large or too small, the charging efficiency will be reduced. For high-current fast-chargers, it is also necessary to specially design the charging method of the phone battery charger in order to improve the charging efficiency.
