The data line of 6A can use the charging head of 5A, but it is not recommended to use it for a long time. In order to let more friends know about the charger and data cable, I'd like to popularize science for you.

1： Charger knowledge

The charger is a charging device that uses high-frequency power supply technology and advanced intelligent dynamic regulation charging technology. All charging needs a stable power supply. For example, the common mobile phone charger is composed of a data line and a charging head.

According to the working frequency of the circuit, the charger can be divided into power frequency and high frequency. The power frequency adopts the principle of conventional analog circuit. Its internal power components (such as transformers, inductors, capacitors, etc.) are large in volume and usually produce low noise under large loads. However, under the harsh power grid environment, its resistance performance is strong, and its reliability and stability are stronger than those of high-frequency machines. The high-frequency machine uses the CPU chip (CPU) as the processing center, integrates the complex hardware and simulation circuit into the single-chip microcomputer, and controls the operation of UPS through software programming.

2： Working principle of mobile phone charger

In fact, all mobile phone chargers are a stable power supply to provide stable working voltage and sufficient current. As we all know, the standard voltage in China is 220 V, which can not directly charge the mobile phone. The mobile phone charger converts the high voltage pulse of 220 V into a low voltage of 5 V, and then converts it into a regulated power supply of 5 V through rectifying and stabilizing circuits. In other words, the mobile phone charger can convert high-voltage AC to low-voltage DC.

The output parameters on the charger are generally 4.4 V / 1 A and 5.9 V / 400 Ma, that is to say, the output 4.4 V can be used for 4.5 V equipment and the output 5.9 V can be used for 6 V equipment.

The data line of 6A indicates that the current of the charging head is only 1A larger than that of 5A, so the difference in output voltage is not great, and it will not cause the charger or mobile phone equipment to generate heat quickly. Therefore, it can be universal. However, for the long-term stability of mobile phone and other equipment, it is not recommended to use the data line of 6a to connect the charging head of 5A for a long time.
