Netease Smart Manufacturing · Bullet Charger Trial Report

Thank Lei Feng Love to play computer games I was lucky to win the bid for the trial activity of NetEase Smart Manufacturing Bullet Charger held jointly with Hangzhou NetEase Yanxuan Trading Co., Ltd. and became a trial user.

As for the car charger, I won the lottery for the second time. The first time was the trial activity of Netease Cloud Music car charger half a year ago. The report is connected to: //t.cn/RIxHPCX . This time, we just put the latest bullet car charger and cloud music car charger together to make a horizontal comparison with the standard car charger attached to Mickey's DASH CAM.  

1、 Packaging appearance.

The appearance package of Netease bullet car charger is a box with white tone. The front of the box is very simple, with only one LOGO.

There are stickers on the bottom of the machine.

The back of the box is printed with the parameters and model of the charger, as well as the manufacturer and other information.

Compare it with the case of Netease Cloud Music Car Charger. The box is one circle larger than the cloud music box. The box of cloud music is a simple kraft paper package.

After opening the package, there was a silver bullet truck charger in the middle of the box.

After taking out the car charger, there is a protective foam and instructions inside.

The charging parameters are written in the instruction manual. The input end of the bullet charger is 12-24V adaptive, which can be compatible with the 24V cigarette lighter of both gasoline cars and diesel heavy-duty vehicles. The charger can support dual port co output charging. When single port is used, the maximum current of each single port is 2.4A. When dual ports are jointly output, the total maximum current is 3.4A.

2、 Charger appearance

The appearance of the bullet is brass. It is heavy when held in the hand. It has a bright silver appearance and is very beautiful.

LOGO and NetEase Smart Manufacturing are printed on the outside of the charger. This "Smart Manufacturing" is different from ordinary "Manufacturing". Recently, NetEase has been designing and producing household intelligent electronic devices. Cloud music vehicle mounted Bluetooth charger is one of them, as well as NetEase intelligent plug-in board. The change from "manufacturing" to "intelligent manufacturing" shows NetEase's determination and ambition in the field of intelligent devices in recent years.

The charging current and other parameters are printed on the back of the charger.

The positive and negative contacts of the charger are carefully designed spherical. There is a circle of black insulating pads on the positive and negative fingertips.

There is a dark white plastic layer between the black base plate and the silver shell of the two side by side USB jacks on the front of the charger. This is the power on indicator.

The golden finger of USB interface is neatly made of golden yellow copper, and low resistance can reduce loss and heating.

Plug the charger into the car, and when it is powered on, the ring indicator light will light up, and the dark white plastic layer will turn into bright white, which is very beautiful.

Viewed from the side, the exposed charger is very short, integrated with the cigarette lighter interface.

This is not only beautiful, but also does not affect the shift operation.  

3、 Horizontal comparison of charging head

In addition to a NetEase Cloud music car charger, I also have a standard dual port charger for Mijia DASH CAM.

Put them together and compare them. Cloud Music has the largest car charger and the smallest bullet charger. The exposed charging part is also the smallest bullet. The shells of Mijia charging head and cloud music charging head are plastic, while the shell of bullet charging head is all copper, which means it is durable and can dissipate heat quickly, ensuring the safety of the charging head.

In terms of charging parameters, the maximum charging current of Mijia charging head is 2.1A; The maximum single port capacity of Netease Cloud music charging head is 2.4A, and the maximum total capacity is 4.2A. The maximum single port of the bullet charging head is 2.4A, and the maximum total is 3.4A. All three are 12-24V wide voltage adaptive. The drawback is that the maximum charging current of "bullet" is 0.8A less than that of "cloud music".

Insert the three charging heads into the three port extended cigarette lighter. Obviously, the bullet charger is the smallest and most beautiful.

The exposed part of the bullet charging head is also the shortest and the most space saving.

Compared with Netease Cloud Music Charging Head, the length is half as short.

All three charging heads have indicator lights. But the most beautiful and obvious one is the circular indicator light of the bullet head. The indicators of Cloud Music and Mijia charging head are all in the USB interface, which is not as obvious as the ring light of the bullet head.  

4、 Charging test

During the charging test, first load the bullet and measure the voltage. No load 4.98V.

I still use my GPD win handheld notebook to test. When the handheld computer is turned off, the maximum charging current can reach 2.7A. Connect the power off GPD win to the USB power meter, plug it into the bullet charger, and you can see that the maximum charging current is 2.76A, and the voltage is still 4.99V, which does not decrease. It can be seen that the single port maximum current output of the bullet can exceed 2.4A, and the official figure is conservative.

After charging for a while, the voltage of the charger has been stable between 4.98-4.99V, and the current has been stable at 2.7A. Thanks to the excellent workmanship and the design of the copper housing, the bullet charger is not hot at all. It can be seen that the workmanship and quality of the bullet charger are very guaranteed.

5、 Summary

Through horizontal comparison and test, the bullet car charger made by NetEase Smart is the best in terms of appearance, material, size and indicator mode. After various rigorous tests, the bullet charger can still maintain a stable voltage of 5V no matter how large the charging current of the load is. Without voltage fluctuation, the charging electronic equipment will not be damaged, which ensures the safety of electronic products and the safety of the charging head. The copper shell is strong and durable, which is also conducive to heat dissipation and stability. Don't underestimate the safety of an on-board charger. Only when the charger is safe, can our car not be damaged. Of course, there are some shortcomings. If only the charging current could be increased a little, it would be better if it was the same as the 4.2A of Netease Cloud Music Car Charger.

Netease smart manufacturing, smart manufacturing by heart, through the evaluation of Netease's two charging heads, I believe that most of us will have a new understanding of Netease smart manufacturing. For those of us who own cars, we can only achieve the following goals with a bullet mounted charger:

Your car is safe and risk-free,

Travel power is guaranteed,

The electronic equipment shall be charged at any time,

Never cut off power and use it at will.
