Write in front:

In the morning, I was gently awakened by Jianping. It was already ten o'clock. The sadness of saying goodbye to dinner last night seemed to continue. Several people in the dormitory seemed to be slow. Several big men helped me pack things with all their hands.

I didn't stop or speak. I lit a cigarette and sat on the bed where I had slept for four years. Now only the bed is left.

That day, I was the first one to leave the dormitory and school.

Along the way, Jianping, the eldest, the second, the fourth, Jun， Also, I walked side by side on the road, but I felt a little cold because I should hang. Later, I knew that it was the shrinkage of pores.

The alcohol paralysis is still on my head, but the paralysis in my heart makes my eyes extremely weak.

Red, like a rabbit.

Along the way, there were many teams like us, including six, five, seven and eight, The most spectacular is a team of five people. No, it should be a team of six people. There are five women in the front, and four of them are standing on their backs, crying like death. After walking on their backs for a while, they should hold their heads together and cry and have a rest, and then go on. Of course, the most aggrieved man behind is the man who is pulling the box and backpack.

It's never a long way to see you off. The car is whistling.

Boss: It's convenient to contact often!

Second child: Work hard and get rich to mix with you!

Fourth child: See you in Shenzhen!

Jianping:

Jun ：……

I don't remember what they said at that time. I didn't hear it clearly. I watched Jianping's mouth move, and then we hugged. The tears still in the eyes would not move. Jianping's embrace undoubtedly gave it kinetic energy to flow out of the eyes, so I personally verified the formation principle of the throwing line, and I cried

Whoosh

The car has started. When I saw Jun's sad eyes, I remembered that I hadn't hugged him, Turn on your phone...

Mom, there is no electricity.

The above has nothing to do with today's trial theme.

If only there was a mobile power supply in those days...

Specifications:

Beaver Yike Mobile Power, jointly developed by Beaver Electronics, Jiajian Geometry and Zongjiang Industrial Design Team, is a mobile power that supports fast charging. It supports Yike Car Charging and all Macbook power adapters except TTYPE-C interface to achieve fast charging. The power capacity is 5000mAh. It can store about 1250mAh of power after 15 minutes of charging, which is about the power of an iPhone. It takes about 1 hour to fully charge.

The specific parameters are as follows:

From the parameter point of view, in the environment of mobile power market price shopping, beaver moment mobile power ingeniously uses multi-threaded charging technology to realize the rapid charging of mobile power, which solves the pain point of industry mobile power that can be fully charged within 7 to 8 hours, and also gives users a choice.

Unpacking experience:

Beaver Moment Mobile Power Box is small in design. It is packed in paper boxes and made of soft materials. There are obvious extrusion marks on edges and corners during the delivery process. The printing design of the box follows the simple route. There is nothing on the front except the outline sketch of the product, which is also eye-catching.

The side product name and logo printing also follow the simple style.

Personally, I think the design of the back of the carton is more casual. The text is too concentrated on the top and bottom, and the middle is slightly monotonous.

When I opened the box, I finally saw the true face of Lushan Mountain. The surface of the aluminum alloy shell was treated with roof sanding, and the metal texture came to my face. However, the fixed partition inside the carton is severely deformed, and it's a tough power supply. Who let you catch up with the Double 11..

Products can wander around in the box.

The internal fixed baffle plate and support have been deformed.

The four corners are damaged to varying degrees.

While complaining about the Double 11 Festival, the packaging designers of Beaver Mobile Power Supply were also asked to pay attention to the hardness of the materials, and the results of the vibration and drop tests must not be too ideal.

The product manual can be seen after taking out the power supply.

The logo of the large product in the middle is nothing but a consistent simple design.

Interface introduction, product size, precautions, etc. Very considerate design.

After searching for a long time, I didn't see the wire. Well, I believe you all have it. If you save the cost of wire rods to reduce the price of products, it will be a good chess game.

Let's have a family photo.

Now let's take a look at today's hero.

Front view of Beaver Yike mobile power supply. The design style is very simple. The whole body does not have a button. A round pendant in the upper left corner is very delicate. Four tiny holes are arranged in the lower right corner of the diagonal line for decoration. These four holes also have a function of displaying power.

Detail drawing of power display hole.

Gently shake it, the power indicator light will wake up, and the four blue leds at the bottom of the four holes will light up. It will become like this. Is it enchanting?

The four lights represent 25%, 50%, 75% and 100% of the power respectively, which is easy to understand.

When the blue LED lights up, there will be blue light exposed from the micro USB hole at the bottom. I wonder if it is the designer's intention?

Back view of Beaver Moment Mobile Power Supply. The upper cover adopts the integrated floor and ceiling design, and the lower cover It is still a metal bottom cover, which is treated by the same sanding process, and is attached with 4 hexagonal socket screws. The LOGO area is occupied by Lei Fengjun, and the product nameplate printing is concentrated at the lower part, with a consistent simple style.

Side view of Beaver Moment mobile power supply. Integrated design, extremely aesthetic, flawless.

The beaver moment mobile power supply has designed a unique round pendant hole on the upper part, which is very delicate and adds color to the square and upright shape. Like one.

Well, after looking for a long time, I finally found a small flaw. One corner seems to have been knocked again. It should be a raw material problem. Is it a bit picky?

The edges and corners on the side of beaver moment mobile power supply adopt CNC technology and small R angle design, which is very smooth and does not cut hands.

Personally, would the gloss be better if there were more CNC processes?

The layout of input and output interfaces at the bottom of Beaver Moment Mobile Power Supply: the leftmost micro USB interface is common to most mobile phone charging data cables. 5V1A input, which takes about 7 hours to fully charge, is the slow charging interface of the power supply; The center is a standard USB interface, 5V 2A/1A output, and the maximum output current can reach 2.4A, which can be automatically identified according to different devices; On the far right is the Macbook Pro fast charging interface, which uses the multi-threaded charging technology. According to the official introduction, it can be filled in one hour, which is also the main feature of this product.

Does it look cute?

The peripherals of beaver moment mobile power supply adopt integrated metal design, which is flat and smooth, and it is effortless to stand up.

Stand up to look more slender.

The overall weight of Beaver Moment Mobile Power Supply is 180g, and two mobile phones can be lifted gently through the pendant. The mobile power supply with such high appearance and light weight should be My sister's favorite.

The width is also very suitable, even the girl's small hand should not have pressure.

It feels great when you hold it in your hand.

The HandJoy handle is more slender than the others.

Does the small shopping cart fit..

Beaver Moment Mobile Power and Sony Xperia A2 mobile phone appeared on the camera, with a circumference slightly larger than the 4.3 inch mobile phone.

The thickness of Beaver Moment Mobile Power is compared with that of Sony Xperia Tablet.

Undoubtedly, Beaver Moment Mobile Power has a high appearance. As a mobile power, it also depends on its internal accomplishments.

Unfortunately, I don't have a Macbook Pro power cord, so I can only give a brief introduction to slow charging and its output.

First, look at the input performance of Beaver Moment Mobile Power.

The trial equipment is as follows:

The power adapter is Sony ACC-247, and the output is 5V 1.5A.

Micro USB mobile phone charging data cable, no features, no more introduction.

White tail, USB voltmeter, cheap and easy to use.

Connect the power supply and charge slowly through the micro USB interface.

Before the beaver mobile power supply was plugged in, the no-load voltage of the power adapter was 5.2V. After the mobile power supply was plugged in, the voltage was 5.1V and the current was 0.91A, basically meeting the requirements. There is no heating during charging.

Since a complete charge and discharge has not been done yet, the conversion rate cannot be calculated. The conversion rate of mobile power supply is generally between 75% and 85%.

Next, let's look at the discharge process. I just have a lithium polymer mobile power supply on hand. By the way, let's make a comparison.

The no-load voltage of Beaver Yike mobile power supply is 5.31V.

After connecting the mobile phone (Xperia T2, non fast charging), the voltage is pulled to 5.2V, and the current is 1.2A, which is relatively generous.

By the way, look at the mobile power supply at hand. It has no load of 5.2V.

After connecting the mobile phone (Xperia T2, non fast charging), the voltage is pulled to 5.08V, the current is 1.06A, and the charging efficiency is much worse than that of beaver.

Trial summary:

At this point, Beaver Moment Mobile Power Unpacking Experience came to an end temporarily.

Through a short play, I am very satisfied with this mobile power supply. With a slim figure, clean interface, smooth lines, simple and generous design, and thick metal texture, I have to admit that beaver's appearance is the highest among mobile power supplies I have ever seen. It's just good to hold it in the hand, the size is appropriate, and it's very comfortable. Unfortunately, it is impossible to experience beaver's fast charging. According to the official figures, the input voltage of the fast charging interface is 14.5~21V, and the input current is 3A. The impact of such a large current and voltage for a long time must be a great test for beaver's main board and component selection, which often has a great impact on the cost of mobile power. From the perspective of 5V USB output, beaver performs very well. It is a product worth recommending.

During the trial, I also found some small problems, and I hope Beaver's engineers can identify and improve them.

1. The material of the packing box is too weak to protect the product during transportation;

2. The charging line is not configured officially, and the wire materials in the hands of users are quite different, which affects the charging performance;

3. If equipped with a storage bag, it will feel better;

   
   

Finally, thanks for the trial products provided by Lei Feng. Thank you!
