Hello, everyone. The meeting will answer your questions. Can the computer charger charge the mobile phone? can the computer charger charge the mobile phone? many people don't know this. Now let's take a look at it.

Answer:

1. If the PD protocol charger is supported, the computer charger can charge the phone, but it is generally not recommended to use the computer charger to charge the phone. If the phone has an original charger, it is recommended to use the original charger. The charging head of each charger has a different output milliampere. If it exceeds the voltage that the phone can withstand, it will cause some harm to the phone. If you want to know whether the tablet charger can charge the phone, you must first really understand how the charger works.

2. How does the charger work?

3. One end of the plug is mainly connected to the 220 V AC socket, and the other end is connected to the equipment through a special data line. The 220V AC from the main power supply is first converted to high voltage DC through the rectifier circuit. Then the high-frequency and high-voltage pulse is converted into high-frequency and high-voltage pulse through the switch tube, and then into low-voltage pulse (such as 5V) pulse through transformer, and 5V low-voltage pulse is converted to 5V stable DC by rectifying voltage stabilizing circuit; in the process of changing from 220V AC to 5V DC, the transformer, rectifier circuit and voltage regulator circuit cause the transformation effect, but only change the form of power supply (from high-voltage AC to low-voltage DC). However, after the user connects the device, the charger begins to carry the load, and at the same time, the current transmission begins. The current flowing through the charger depends on the state of the load, which can be checked by the formula. Therefore, when the charger is within the rated capacity, how much current the charging device needs, how much current the charger will provide, and the current ratio of the charger depends on the consumers themselves; nowadays, general rechargeable electronic devices are basically equipped with special charging circuits. the current can be completely limited according to the situation. Therefore, there is no need to worry about these problems. In addition, if the phone charger charges the tablet, the phone charger will charge the tablet with the maximum output current, but the charging time will be longer. Now there are so many chargers that they will inevitably be mixed. However, due to the design differences between different brands, if it is a mash-up, try to choose the same brand, must choose the authentic. If a fake charger is used, the problem will not be the price of a mobile phone.

This is the end of this article. I hope it will be helpful to all of you.
