Does the data cable of the charging head 2A also have to be 2A?

No, they can all be used.

If the 3A data cable is equipped with a 2A charger, the charger can only provide a maximum of 2A current, so the data line can only conduct 2A.

1. Charger.

The charger adopts high-frequency power supply technology and advanced intelligent dynamic adjustment charging technology. On the basis of the principle of traditional analog circuit, a power frequency motor is designed. The internal power components of the machine (e.g., transformers, inductors.

capacitors, etc.) are relatively large. In general, the noise is less when the load is larger. However, compared with high-frequency motors in harsh power grid environments, it has strong resistance performance, reliability and stability.

2. Types. There are many chargers such as lead-acid battery chargers, VRLA battery testing and monitoring, nickel-cadmium battery chargers, nickel-metal hydride battery chargers, lithium-ion channel battery chargers, lithium-ion batteries for portable electronic devices.

Chargers, lithium-ion battery protection circuit chargers, electric vehicles.

Battery chargers, car chargers, etc.

Extended Content:

The 1A or 2A indicated on the charger is the current intensity of the charge.

The simple understanding is the charging speed of charging. The common current indicators of mobile phone chargers are 500 milliamps (0 5A), version 1A, 2A, and the larger the more.

Fast. For example, Apple 5s

It is a 1560 mAh battery, which is fully charged in about 1 5 2 hours with a charger of 1A, and full in about 1 hour with 2A.

No, the charging head just says that its maximum power is 2A, and the data cable is enough.

Now the data line of the smart phone is the same.

It's not....A lot of them are OK, but they use the same original charger....

Summary. OK.

The 5V2A charging head can be used with a 3A data cable.

The current allowed by the charging cable is greater than the maximum current output by the charging head, so it is safe to use.

If the current output of the charging head is greater than the maximum allowable current of the charging cable, it is unsafe to use.

3A is only the maximum current of the data cable design, and 2A and chargers can use 3A data cable.

Can a 5V2A charging head use a 3A data cable?

It can be 5V2A charging head, and it can use 3A data cable. The current allowed by the charging cable is greater than the maximum current output by the charging head, so it is safe to use. If the current output of the charging head is greater than the maximum allowable current of the charging cable, it is unsafe to use.

3A is only the maximum current of the data cable design, and 2A and chargers can use 3A data cable.

Fast charging depends on the charging head or the cable.

Charging head. All right.

Ask about custom messages].

The data line is divided into 1a and 2a per mu.

If the voltages are equal, the difference between charging heads 1A and 2A is:

1. In appearance, the hall of 2a is better than that of 1a;

2. The difference between charging speed and slowness, theoretically using 2A can shorten the charging time by half compared with 1A, but if the battery capacity is small, the charger with 2 A is easy to damage the battery or reduce the life, and the general lithium battery charging current can not be exceeded.

A and 2A refer to the current output of the charging head. The output current is large, and your load is easy to be full (short time), and the output is small (long time), but the charge stability is good. The battery is durable.

Yes, the thicker the copper wire of the core of the charging cable, the greater the current it can withstand, the 3A data line is equipped with a 2A charger, because the charger can only provide a maximum of 2A current, and the random data line can only conduct 2A.

1. Charger.

The charger is a high-frequency power supply technology and uses advanced intelligent dynamic friend absolute adjustment charging technology. The power frequency machine is designed based on the principle of traditional analog circuit, and the internal power components of the machine (such as variable guess spring voltage device, inductor, capacitor, etc.) are relatively large, and there is generally less noise when the load is large, but the model has strong resistance in the harsh power grid environmental conditions, and the reliability and stability are stronger than that of the high-frequency machine.

2. Types. There are many chargers, such as lead-acid battery chargers, VRLA battery testing and monitoring, nickel-cadmium battery chargers, nickel-metal hydride battery chargers, lithium-ion battery chargers, portable electronic device lithium-ion battery chargers, lithium-ion battery protection circuit chargers, electric vehicle battery chargers, car chargers, etc.

The 1A or 2A marked on the charging wheel Sun electrical appliance is the current intensity of the charge.

To put it simply, Sobo is the charging speed of charging. The common current indicator of mobile phone chargers is 500 milliamps (, the bigger the faster. For example, the Apple 5S has a 1560 mAh battery, which is fully charged in about an hour with a 1A charger, and full in about 1 hour with a 2A charger.

Difference: The output current of 2A is larger than that of 1A, if the output current of the original charger of the mobile phone is 1A, then use the 1A data cable. If you use a 2A data cable, you will find that the charging time is shortened, the wax leak chain mobile phone is hotter when charging, the mobile phone battery may bulge, the battery life is shortened, and there will be potential safety hazards when charging, generally in a short period of time 1A and 2A data line is not much different.

However, generally good mobile phones have charging protection circuits inside, even if the 2A data cable is used on a 1A mobile phone, it is fine. It is best to use the original charger and data cable. Because some data cables still have lock codes inside, different mobile phones cannot be mixed.

Yes, the 5A data cable is only larger in current carrying capacity and thicker and more durable on the cable, etc., and the data cable is backward compatible.

Yes, it is also possible for a 5A data cable to pass a current of 2A, which will not cause damage to the mobile phone device.

As an accessory product of mobile phones, mobile phone data lines can completely develop the potential functions of mobile phones, and gradually attract people's attention, and the supply and demand of the current accessories market are also increasing. As one of the main accessories of the mobile phone, the data cable is seen a lot on the market, but the original data cable is not seen much, most of them are produced by the manufacturers themselves, of course, the quality and ** are uneven.

The mobile phone data cable was only an ordinary mobile phone accessory at the earliest, mainly used for repairing, testing mobile phones, business people through computer management**, today's data cable application has been quite extensive, making mobile phone logos, upgrading mobile phone operating systems.

and other functions are deeply loved by users, because different data lines will map different functions, so you can distinguish them when you buy.

Yes, and it doesn't slow down, it's still charging at 2A, that is, still using 10W of charging power.

It can be used, but the 5A data cable used on the 2A charging head cannot reach the charging efficiency of 5A, and the 5A data cable belongs to the flash charging cable, and the 2A charging head can only achieve the fast charging effect.

Hope mine is helpful to you

Questions. I used a 5A cable with a 2A charging head, but it charged very slowly.

I want to ask if there is a problem with the phone.

Okay, please wait a minute.

For example, after the 5A data cable and the 2A charger are connected, charge the mobile phone, which may be unfavorable to the charging of the mobile phone due to the internal resistance of the data line, and it is best to choose the charger and data cable that the mobile phone can adapt to.

Dear, it has nothing to do with your phone.

It's a problem with the charging cable.

It is recommended to use a matching charger, and the charging speed will be much slower if it is not matched.

Not good for mobile phones.

Hope mine is helpful to you

Questions. Good. Thank you.

Of course, there is no problem with using a large current, but using a small current will cause the charging to slow down.

Since the wire is only connected to the circuit, the speed of charging also depends on the charging head, the charging head of 2A is the charging speed of 2A, although the current of the wire is 5A, but only 2A.

1A and 2A are electric currents, similar to the grain of electronic devices. In the early batch of mobile phones and other electronic devices can accommodate the current is mostly less than 1A, that is, even if the 2A data line is used, the charging speed is not much different from 1A, because the charging current adapted to the mobile phone is less than 1A, that is, a person's esophagus is only 1A, even if he uses 2A in kind, he can only accept half.

With the progress of mobile phones, the current charging current of mobile phone devices has gradually exceeded 1A, for example, the original configuration of Samsung S4 mobile phones is 2A, which can be fully charged in about 150 minutes. Another example is that the charging current of Apple 6 6plus is also close to 2A, which more or less also means that 2A and fast charging trend.

Seeing this, you will obviously understand that the performance of the 2A charging cable is stronger than that of the 1A, which can effectively improve the charging speed. Then there is a similar reason for our daily common chargers. For example, the car charger that our car owners often use, many car owners are also ignorant of this kind of product, and they are still using a 1A charger to charge mobile phones such as Apple 6 6plus.

At present, the current of car chargers on the market mainly includes 1A, 2A, 1A, 1A can meet the charging of mobile phone equipment, but the speed is slow; 2a can meet the fast charging of more comprehensive mobile phone types; It can not only provide fast charging for all kinds of mobile phones, but also charge tablets. It is not difficult to see that 2A is the trend of the future, and as long as related technologies continue to break through, I believe that there will be more rapid charging devices.
