The charging speed of the mobile phone depends on the charging head or the data cable

We all know that the charging speed of mobile phones is inseparable from the charger. The charger consists of a charging head and a data cable.

Does the charging speed of a mobile phone depend on the charging head or the data cable? To figure out this problem, when the charging head or data cable needs to be replaced, the charging speed of the phone will not be slower than the original one due to the wrong selection.

Let me tell you the answer first: it is not only related to the charging head, but also related to the data cable. What is the specific relationship? How to choose when one of them is broken?

What is the relationship between charging speed and charging head?

When charging the mobile phone, the charging head determines the voltage and current. The voltage and current output parameters are marked on the regular charging heads.

For a very simple example, your mobile phone supports 5V/2.4A, which is 12W charging. If the charging head is broken, and you change to a 5V/1A, that is, 5W charging head to charge the phone, the charging speed will naturally be much slower.

Why does the data cable affect the charging speed?

The data cable is responsible for connecting the mobile phone and the charging head, mainly responsible for current transmission, so it will also affect the charging speed. For example, the power of a mobile phone is equivalent to a bucket, the charging head is a faucet, and the data cable is a water pipe. To fully charge the phone is equivalent to filling the bucket with water.

At present, the Micro usb interface cable on the market can generally transmit a current of 2A, but there are also some charging cables without a signal core, which can only charge and cannot transmit data. The current that supports transmission is only 500mA. You need to pay attention when choosing.

In addition, the length of the data line also has a certain impact on the charging speed. The shorter the data line, the faster the charging speed. Generally, the standard data cable of mobile phones is 1 meter. However, we can also match data cables of different lengths in different usage scenarios. For example, if you use a power bank to charge your mobile phone, it is recommended to choose a short-term cable.

Of course, if you want to charge your phone while lying on the bed or sofa, you don’t need to worry too much about the charging time. You can choose a 1.5-meter or 2-meter data cable, which is more convenient to use.

Finally, to summarize, the fastest charging speed can be achieved only when the charging head and the data cable are selected correctly.
