preface

With the popularity of digital devices rising year after year, various digital devices are also emerging in endlessly. When using a device, it needs to be equipped with a charger, and the chargers and charging cables at home are piled up one by one. As a result, the chargers are often not found when charging. However, in recent years, the smart wind has swept the home appliance industry, and the patch panel products are no exception. Each manufacturer has launched a patch panel with USB output function, which saves consumers who are surrounded by digital products a lot of care.

This time, we are bringing smart patch panel products from "NetEase Smart Manufacturing", a new brand of NetEase, to occupy the field of smart hardware and smart home by launching smart hardware products.

The price of this patch panel in NetEase's "E-mall" is only 58 yuan. Is it worth it? Now let's see.

appearance

Thank you first“ Love to play computer games ”And provide trial products. The outer package is very simple. The white box has only NetEase's logo on the front and NetEase's website.

The parameters of the patch panel are just printed on the back. Here you can see the three dimensions, rated power, USB input and output parameters, design manufacturer and other information of the patch panel.

Inside the package, there are instructions and warranty cards in addition to the patch panel

This patch panel is described in detail in the manual

The appearance of the main body of the patch panel is also very simple. The overall white shell is made of ABS+PC flame retardant material

Netease LOGO is printed on one end of the patch board.

On the front, we can see that this patch panel uses three national standard sockets and four USB sockets

NetEase's logo is also on the plug

The other side of the plug has CCC certification mark and current and voltage parameters

The plug adopts the inverted trapezoid design, which enables the fingers to exert more force when pulling out the plug.

The wires are 1.5m long and also equipped with cable ties

The specification of the line is 3 * 0.75 square meters, which is in good order

There is a main switch on the patch board, which controls the national standard socket and USB socket at the same time.

"Child safety door" on the national standard jack

It is actually measured that with the protection of this safety door, it can prevent children's little fingers and other small things from getting in, and the safety is more considerate.

However, if it is a plug, it is easy to insert it.

The measured distance between the two jacks is 46mm, which can be compatible with a larger power supply device without conflict with the jacks on both sides.

The four USB connectors are arranged in a field shape

Only the corresponding parameter information is printed on the back of the patch panel.

The four corners are respectively provided with silicone foot pads, which are very stable on the desktop.

The hidden design of the power indicator makes the front of the patch panel simpler, but because of the light transmittance, the indicator is not very eye-catching and can hardly be seen when the light is strong.

test

The nominal USB port output voltage is 5V, and the maximum output current of a single port is 2.4A.

The measured output voltage of USB port is 5.17V, which should be supplemented by its own line.

Since there is no false load at hand, the test here uses a power supply with maximum 2A output to compare the current when charging with several mobile phones.

The first mobile phone, the current is about 1.84A and the total power is 9.73W when charging with ordinary power supply

Later, replace the Netease plug board with its own USB, and you can see that the output current can also reach 1.84A. However, due to a certain voltage drop, the total power slightly drops to 9.4W

The second mobile phone has a current of about 1.2A and a total power of 6.2W when charged with a common power supply

Replace with Netease plug-in board with USB, the output current is 1.17A, and the total power is 6W

The third mobile phone, the current is about 1.51A and the total power is 7.9W when charging with ordinary power supply

Replace with Netease plug-in board with USB, the output current is 1.6A, and the total power is 8.21W

Through the above comparison test, we can see that the USB output of this patch panel can reach the maximum charging current of any mobile phone, so the compatibility is very good.

Disassembly

In addition to the appearance, the most important thing is the internal materials and workmanship, so this trial has arranged a disassembly link. Let's take a look at the interior of this patch panel.

Remove the four silicone pads on the back of the patch panel, and you can see the screws. However, the screws are triangular, which should be used to prevent disassembly. However, I have all the tools at hand, which is not a problem.

After removing the four screws, there are still eight clips on both sides of the shell. Pry the eight clips to open the patch panel.

Switch section

Socket part

USB output part

Because the components are on the other side, it can be seen clearly by turning them over. The figure below is the switch part. Two main functions of the patch panel are realized in this part: first, it is integrated“ overload protection ”When the power exceeds the rated 2500W, the switch will automatically disconnect to prevent overload. After the overload is eliminated, the switch can be opened manually.

Another function is“ Lightning protection and surge prevention ”This function is mainly realized by the blue "lightning protection varistor" beside the switch. Varistors can suppress the occasional abnormal high voltage in the circuit and protect the circuit from the damage of high voltage.

Design of integrated copper bar

Compared with products welded or riveted with wires, the safety is higher, which must be praised. At the same time, when the plug is inserted, the contact is also very close to avoid accidents caused by too small contact surface and local high temperature.

USB module

There are many inductances, square fuses and safety capacitors.

There is also a solid capacitor in the middle for filtering the output part

Visually, the materials are very solid, and the total 4A current output is still reassuring.

summary

This NetEase smart patch panel is a product with good appearance just from its appearance. However, after actual disassembly, it was found that the material used for this patch panel is more practical. At this price, it is a great honor for our consumers to have a product that can achieve "integrated copper printing, 4U output, and overcurrent and overload protection", and has such solid workmanship and materials, However, I feel that the indicator light of this patch panel is too dark. It would be more perfect if it could be improved.
