I still remember that some mobile phones of Samsung and other brands used wireless charging technology as an important gimmick and selling point when holding the press conference. Of course, in daily life, wireless charging mobile phones are also very attractive because of their simple operation. However, as far as the author knows, this technology has always been difficult to popularize because of the non-uniform charging technical specifications and other factors.

This time, the VH and wireless charger I got from Lei Feng.com can easily be used for any brand of mobile phones. What magic is there? We will begin to appreciate it immediately.

The outer package of the charger adopts a gray design. In order to adapt to more mobile phones, the base of the wireless charger and the supporting receiver are separately placed in different packaging boxes, so you can see two different packaging boxes.

On the back of the packing box of the base, there are some information about the relevant technical parameters and manufacturers of the product, which is relatively standard.

Seen from the side, the packing box is very thin and simple, similar to the three-layer design of a sandwich. However, the workmanship is not so good. It can be seen that some parts of the middle package have been cracked. I don't know whether it is because of the express company.

Open the packing box, you can see that the charging base is leaking out of the tip of the iceberg. In addition, the product simply printed the instructions on the inside of the packaging box, without any other paper instructions attached.

Instructions are printed on the wireless receiver. However, in fact, the operation of the product itself is also very simple, and you can quickly start using the product.

Let's first look at the wireless charging receiver. It is very thin, and part-time job is like a small piece of cloth. At the top, it is a data line with the nature of noodles. Since the author uses an Android phone, the top interface is Micro USB interface.

However, it can be said that this is one of the major problems that the author found. Because the interface of this port and the mobile phone interface are very closely matched, each plug and pull requires a relatively large amount of effort, so he is very worried about the noodle line and Whether the Micro USB interface will break after long-term plugging and unplugging.

The workmanship of the charging base is very excellent at a glance. The blue version I got this time is very refreshing.

The charging line of the charging base also uses the noodle line, while the position where the base and the USB interface are removed is made of metal, and the material is more particular.

The charging base adopts a round interface, and the surface is made of leather. It feels great! The top layer has VH citation characters and a current pattern. It is about the size of the palm, and actually feels light.

Relevant specifications and parameters are printed on the bottom of the charging seat. It is worth noting that the input of the product is 5V/2A, but the output is 5V/1A, so the output current is a little small. At present, the input supported by mobile phones is generally more than 2A, so it will have a certain impact on the charging speed.

Since the output current of the product itself is 1A, the author took out HTC M7 as the test machine (the standard charger output current is 1A); At the same time, the charging plug with 2A current output is also selected as the source of power supply.

The wireless receiver can be placed in the middle of the charging socket.

Before placement, the indicator light of the base is green; When the receiver is correctly placed, it will turn blue and green alternately. Now, let's feel it through the dynamic diagram:

Plug one end of the charging receiver into the micro USB interface of the phone

Put it into the receiver base, and the charging will start immediately. It can be said that the operation is very simple without too many requirements. As long as the phone is connected to the receiver and placed on the base, it is OK.

Let's look at the charging efficiency:

The author takes 10 minutes as the charging interval to test the charging efficiency. However, what was unexpected was that HTC could identify whether the accessories were genuine or not. After the non genuine accessories were detected, it showed that high-speed charging could be achieved only when the genuine charging line was connected.

After testing, only 2% of the power was charged in 10 minutes.

Of course, the charging efficiency is significantly improved after the use of genuine chargers.

It can be said that this test is not very impressive, but at present, the mobile devices used by the author have very few terminals with rated 1A input. Therefore, the author believes that the output of this 1A is indeed weak.

In addition to the above mentioned output current of 1A is weak, the author believes that the design of the receiver is also general, and the connector is soft, so he is worried that the receiver wire will be damaged if it is used for a long time; In addition, if the charging receiver is attached with a design that is fixed or pasted on the phone shell, its practicability will be greatly improved.

It can be said that the design concept of this wireless receiver is very good, and the appearance is also very beautiful. It is hoped that the performance can be enhanced to reach the mainstream output current (it may need to be equipped with a special charging head), so that the universal performance and practical performance will be greatly improved.

Finally, thanks again for the quality products provided by Lei Feng.com!
