Does fast charging of mobile phones rely on wires or charging heads?

<> "The charging head in the fast charging system of mobile phones is the protagonist, and it is also the first contact of our consumers. For consumers, charging efficiency is a key indicator to measure fast charging technology, and this indicator is to rely on the charging head, how much power of fast charging technology, need to match the corresponding power of the charging head, so when the charging head, consumers can perceive an indicator.

The data cable is what many of us also know, since the iphone8 series of mobile phones have supported fast charging, but you need to buy a special charging head and charging cable, then compared with the ordinary charging cable, the charging cable that supports fast charging also has some special because the ordinary charging cable only has three wires working, two of which are power cables, and one line is a ground wire.

In the fast charging cable, there are basically five wires working, two wires are power lines, two wires are data cables, and one wire is a grounding wire.

Therefore, it is incorrect to simply say that the fast charging system relies on the charging head or the charging cable, and more often it depends on the matching of the two, and compared with ordinary charging mobile phones, the mobile phone power chip suitable for fast charging will be more demanding, so in the fast charging technology,Your phone's batteryThe role of the role cannot be ignored either.

Rely on both the wire and the charging head, but the charging head is the most important.

1. Charging head: The charger needs to meet sufficient output current and output voltage, because the wiring of the charger has a large parasitic resistance, and if you want to achieve a large charging current, the on-load output voltage of the charger needs to be higher.

2. Wire: In the case of fixed charger, high-quality charging cable, interface standards and specifications, will not produce virtual connection, and the loss on the charging line is very low, which will significantly speed up the charging speed of the mobile phone. With a long data cable, the longer the line and the greater the resistance, then the charging speed will be slower.

3. Fast charging is the charging head, line and power management chip.

The result of working together. The charging head is the protagonist, the most important, for fast charging, the charging power is a key indicator to measure the fast charging technology, and this indicator is the charging head. For mobile phones, the fast charging technology of how much power needs to match the corresponding power of the charging head.

Relying on the charging head, the larger the output, the faster the charge. Such as OPPO increases the current, and there are also those like Motorola that increase the voltage and fast charging.

Of course, it's the charging head, and the wire only plays a connecting role.

It should be relied on on the charging head, because the charging head can change the magnitude and amplitude of the current. Whereas, the line is mainly the role of transmission.

The charging head, only the exclusive function can be used for fast charging, relying on such a big head.

The charging head can also be charged quickly by changing a wire, and the charging head is the most critical.

The fast charging of the mobile phone should rely on the charging head, which changes the power of the wire.

Yes, the charging head guarantees the output voltage, and the wire ensures that the resistance is not too large.

It should be a charging head, after all, there is a specially adapted flash charging head.

Both include, flash charging to have a customized battery, charger, data cable, and a variety of circuit design.

Is the fast charging function of the mobile phone the credit of the charging head or the credit of the line? Why?

The power supported by the charging head determines the lower limit of the charging power, while the charging power supported by the mobile phone determines the upper limit. The data cable is mainly responsible for transmission, and is generally charged with the original mobile phone or the charging cable distributed by the charger. The relationship between the charger, the charging cable and the mobile phone is a bit like the relationship between a dam, a water pipe and a household faucet.

The following is illustrated with iPhone charging:

There are two conditions that need to be met for iPhone fast charging, one is the charging head with the Type-C port, and the other is the Type-C to Lightning data cable. iPhone 8 or newer iPhone models can already use the 18W fast charging of the PD fast charging protocol, if the charging head does not have 18W, even if the CTOL data cable is used, it can only be charged with the maximum power supported by the charging head.

Fast charging of the phone depends on the data cable or the charging head.

Fast charging of mobile phones is related to both the data cable and the charging head. The charging head is the source of the current output. Determines the voltage and current, the maximum output power, and also determines the maximum charging power that can be provided to the phone.

The quality and performance of the data cable also have a certain impact on the charging efficiency, and the material of the data cable determines the level of current loss in the transmission process. Therefore, mobile phone fast charging is inseparable from the data cable and charging head.

Precautions for fast charging of mobile phones.

When using fast charging, be sure to know in advance whether your mobile phone has a "fast charging protocol", that is, whether your mobile phone supports fast charging. Generally speaking, smartphones that have been marketed in recent years support fast charging.

Fast charging can only solve a temporary problem. Generally speaking, between 0-70% battery life, using fast charging can save a lot of time. More than 70%, the cumulative time difference between using fast charging and ordinary chargers will not be very large.

Try not to mix chargers. Before using a fast charging device, you need to confirm the type of mobile phone it supports to avoid battery loss due to mixed use.

Fast charging is the joint role of the charging head and the charging cable, both play an indispensable role, the relationship between the two is complementary, relatively speaking, the role of the charging head is greater.

Fast charging is the result of the charging head, line, and power management chip working together. The charger must have sufficient output current as well as output voltage. Since the wiring of the charger has a large survival resistor, if a relatively large amount of charging current is to be completed, the no-load output voltage of the charger must be higher.

In the case that the charger is fixed, the high-quality charging cable, standard interface, standard, is not easy to cause virtual connection, and the wear and tear on the charging cable is extremely low, which will significantly accelerate the charging rate of the smartphone. The longer the mobile phone charging cable, the greater the resistance, the slower the charging efficiency.

Introduction to the charger

The charger is a charging equipment that uses high-frequency power supply technology and advanced intelligent dynamic adjustment charging technology. Chargers (chargers) are divided into power frequency machines and high-frequency machines according to the working frequency of the designed circuit.

The power frequency machine is designed based on the principle of traditional analog circuit, and the internal power components of the machine (such as transformers, inductors, capacitors, etc.) are larger, and there is generally less noise when running with a large load, but the model has strong resistance in harsh power grid environmental conditions, and its reliability and stability are stronger than that of high-frequency machines.

Yes, but it's still ordinary charging, if you want to identify the icon of the electricity in the mobile phone charging animation, one electricity is ordinary charging, two are fast charging, and the super is otherwise marked. It has little impact on the mobile phone, mainly depending on the charging frequency, and wireless charging is harmful to the mobile phone.

It doesn't have much effect, but it's not very good for the phone battery, so it's not recommended to use it this way!

As long as it can be plugged in, it can be used, as for whether it has an impact and how much impact is there? It is impossible to judge accurately.

It is not recommended to use an ordinary data cable, it is better to buy a matching cable!

Don't lose a big one because it's not worth it! ok？
