Take the iPhone for example. Starting from the iPhone 12, the whole series is not equipped with a charger, which means we need to pay for the charger ourselves. If the charger is selected, it is also good for the mobile phone. As an important mobile phone accessory, the charger has become a consumable. Many people have the same situation. If they buy a new charger, they will replace it in less than three months. It is because the charger is not selected well, it wastes money and time. So it is very important to buy a good mobile phone charger.
1.Look at the input voltage
For example, 100 ~ 220V / 50 ~ 60Hz belongs to broadband input voltage. The input voltage of domestic and foreign charging heads is different. For example, the foreign charging head has only 110V voltage. If it is used in China, the consequences can be light or heavy.
2. Look at the output voltage
The output voltage of about 4.9 ~ 5.1V can be selected. The larger the output current, the better. However, the allowable output current ≠ the real output current. What I can tell you is that if the output current of the charger is too small, the charger will be in the state of full load, so many people buy chargers that are hot or unstable during charging.
