How many amperes does it take to charge a mobile phone?

To know how many amperes the charging head is, just look at it directly.

For the output parameters marked on the original charger (line charger), such as output 5.0V/ 1A and output 5.0V/1500ma-11200, refer to the relevant parameters of the internal regulated power supply.

The lithium-ion battery charger commonly used in mobile phones adopts constant current and limited voltage charging system, and the charging current is generally around C2, that is, the charging rate is two hours. For example, a 500 mA battery is charged at 250 mA for about two hours, and then charged at a constant voltage.

Correct charging method

When charging the mobile phone for the first time, the longer the charging time, the better-3 hours is better. Avoid overcharging. Don't expose the battery to high temperature or cold places, such as dog days, and don't expose the mobile phone in the car; Or take it to an air-conditioned room and put it in a place where the cold wind blows directly.

When charging, it is normal for the battery to be a little hot, but it should not be "high fever". In order to avoid this situation, it is best to charge at room temperature (about 26 degrees) and don't cover anything on the machine.

Mobile phone batteries should avoid contact with gold and silver jewelry, watches, metal ornaments, pins, etc. Just in case. Because when the socket of the mobile phone battery contacts the conductor, a short circuit will occur, which will lead to an increase in the battery temperature. High temperature will volatilize the chemicals in the battery, produce very dangerous gas, and even explode in severe cases.
