Nowadays, people rely more and more on smart phones. Smart phones are often used by people to access the Internet, which leads to insufficient power of mobile phones. Therefore, people often use chargers to supplement power for many times, and the data cable is also plugged and unplugged for many times, resulting in damage to the data cable, and more importantly, damage to the charging port. So is there any way to reduce the frequent plugging? This is the trial product "Green Juneng ZTE Magnetic Suction Data Cable" launched by Lei Feng and llano Green Juneng today. You can basically say goodbye to the previous charging method by using it. Next, we will take you to have a deeper understanding of this product.

Simple unpacking

From the perspective of the outer package, the outer package is black, and the approximate shape of the magnetic line of force can be vaguely seen in the black. What does the label of "24K" mean?

On the back of the box, briefly describe the characteristics of the product (30000 times of plugging, etc.) and the quantity of products in the package.

Inside the box is the magnetic line of force wrapped in foam. There are two plugs in total, probably to prevent loss, and one more plug in case of accident. There is also a strap that can be tied on the line for convenient storage. There is also a blue belt.

Description and trial

This product is a second-generation product, which has improved a lot on the basis of the first generation. Compared with the first generation, the width of the second generation is significantly reduced. The second generation thread is woven with nylon, making it more durable. The second generation has also designed positive and negative adsorption, so that it can always be charged no matter how it is used. chart

Since it is a magnetic charging line, the size of the magnetic force will also affect our experience. With the Nd-Fe-B magnet in the United States, the Japanese rare earth formula has helped to enhance the magnetic force. There are also some features as follows.

● One second connection and instant charging

● Current transmission up to 2400mAh

● All aluminum alloy metal shell

● The charging port can automatically adjust the charging current

Take out the thread. The thread has a strap that can be tied at any time. There is an LED light for charging prompt on both sides of the cable head.

Look at the contact diagram inside the line. There are 5 contacts in total.

At the beginning of the trial, there was a voltage and current USB detection line in my hand, so I tested it.

This figure uses 4A resistance to measure the line. It is 3.94V, 2.65A, which is a little larger than the official 2.4A, and may have errors. Replace with 2A resistance measurement.

The voltage rises and the current drops. For the test of three mobile phones, the first step is the mapping of the original line. Red rice note3

There is still one undetected. The magnetic line of force is the same as the original one, so no pictures will be uploaded here. The transmission speed has not been measured, because I think no one dares to use it to transfer files. If the file is not sucked, the transmission will fail.

To sum up, the official promotion of magnetic line of force is 5V, 2.4A charging output. In fact, it is a little lower in the era of fast charging, but fast charging has not become the mainstream. And not every mobile phone's charging current is 2.4A, depending on your mobile phone. Some mobile phones have a slightly higher current, while others will slow down. If you want to know your charging current, you can buy a detector to test it. I personally test whether the charge is rising while playing with mobile phones. There is also a pity that the back plug of each mobile phone is not very tight. The red rice note can easily suck out the other half of it by its own suction. I hope the manufacturer can make the bulge on the inserted mobile phone bigger so that it is not easy to be sucked out when inserted into the mobile phone. Advantages: The thread is made of nylon, which can prevent the two ends from splitting after a long time. The thread is also joined with a very intimate one that can bind the thread. After the phone is inserted, it can not be pulled out, which acts as a dust plug.

Hole time

I came up with the next thing with a fever in my head. Now there is a kind of thing called magnetic force line. Most of our mobile phones are charged at night, overnight. From the magnetic force, I thought of electromagnet. The electromagnet can control the magnetic pole through the current, and the magnetic force size can also be controlled. Then there is such a charging line. Install the S/N pole at the end of the plug-in mobile phone, and the magnetic pole is controlled by the current at one end of the line, If the line detects that the phone is fully charged, it is good to automatically change the magnetic pole to make the phone out of the charging state. Generally, there are two holes on the mobile phone, one is the charging hole and the other is the headphone hole. For charging, a tail can be left in the mobile phone as a dust plug. Then a magnetic headphone cable can be used to plug the headphone hole. Is it good.
