preface
With the continuous development and popularization of intelligent technology products, each of us now has two or three intelligent electronic devices or even more. Although these products can enrich our daily life, they also cause a lot of trouble. It is obvious that charging is a problem, especially when we go out for a long time without power supply equipment in the surrounding environment to provide power for our smart electronic products? Although mobile power can solve the problem of power endurance of mobile devices for us in a short time, what can we do to solve the problem of power failure when the mobile power is exhausted? After experimenting with various mobile power supplies with different functions and characteristics, we'd better try this environmentally friendly and practical charging artifact with self-sufficient power supply ----- China Aerospace Solar Mobile Power Supply "Solar Cube"
Solar energy, as a sustainable, renewable and environmentally friendly energy, has been paid more and more attention. Since its development, it has involved various fields, and its technology has become more mature and widely used. This trial China Aerospace Solar Mobile Power "Solar Cube" was designed and developed by Beijing Time Core Technology Co., Ltd. It is a solar mobile power that can be freely spliced, What's special about this solar mobile power supply? Don't worry, let me tell you.
Appearance display
The package of the Sun Cube is made of cardboard, mainly white, rectangular structure, and simple packaging design. The front of the package is printed with the relevant introduction of the Sun Cube mobile power supply, in which the upper right corner is printed with the words of China Aerospace Honorable Products, and the back of the package is printed with the relevant parameters of the Sun Cube. Although the packaging style of this sun cube is simple and plain, the words "China Aerospace" printed on it is enough to prove that the treasure inside is not simple, because the trademark registered beginning with "China" is basically not allowed to be registered unless it can represent the country.
When you open the box, you can see the sun cube produced by China Aerospace, which is mainly black, supplemented by gold, and a manual of solar mobile power products. Of course, the signboard of Lei Feng's machine trial platform, Lei Feng Love to play computer games The trial platform is a trial platform for the display, exchange and promotion of outstanding products. All kinds of famous and outstanding brands can find their presence on this platform. Here, I am very grateful for the trial opportunities offered by the Aigoji trial platform.
This China Aerospace Solar Mobile Power Supply "Solar Magic Cube" designed and developed by Beijing Shidai Minxin Technology Co., Ltd. is slightly different from the portable soft solar charging panel on the market. The difference is that it is inflexible, but it adds the magnetic suction function, which can be disassembled and expanded. It is much more flexible than other single solar charging products. The sun cube is wrapped with metal, and the middle plate is black with Chinese aerospace words and icons, which makes people feel thick and strong. But when I opened it, I thought it was a flip, but in fact, just pull the upper and lower plates back and forth. Fortunately, it was found in time without causing an accident.
The upper and lower light absorption plates can be automatically absorbed and combined into a square solar mobile power supply - the sun cube. As can be seen from the following figure, there is a small LCD in the middle of the combined sun cube. The black solar absorption plates on the left and right sides are wrapped with metal, which are very shiny in the sun.
On one side of the back of the solar panel is printed the words of China Aerospace and the icon, which gives a solemn and sacred feeling. On the other side is printed the words of solar mobile power, etc. The solar panel power of the Solar Cube is 5.1 W, and the standard output voltage is 5.2 V. When two solar panels are connected and placed in the sun, the LCD will display the words of 0.00 A, It indicates that the activation connection is successful and can be used. Since the electronic equipment has not been connected, the current output is 0.00A It is understood that the Sun Cube uses imported KEVLAR backplane, which is light in weight and high in strength, puncture resistant, and has a frosted alloy frame. Each corner has a small hole, which is convenient for outdoor wear and carry. The magnetic suction point on the frame uses electroplating technology, which can effectively ensure the conductivity of electric energy
The Sun Cube is a portable and efficient mobile power supply that can be freely spliced. It uses highly efficient chips developed independently, which can realize parallel circuit, automatic reset and other functions. The maximum output voltage of multiple sets of series connection is 20V, and the maximum power after multiple sets of parallel connection is 10W. The maximum output current is 1.8A. It only takes 2.5 hours to fill the iPhone 7 with monocrystalline silicon solar panels, Ordinary solar mobile power takes 3 hours
The USB power interface of the sun cube is located in the middle of the top. We only need to connect electronic devices such as mobile phones or mobile power supplies with the sun cube through the USB power cable and place the sun cube in the sun to charge the electronic devices
The combination of the sun cube is very simple. It can be automatically adsorbed by aligning two solar absorbers at the interface, and the suction is very strong. It can be fastened without additional buckles. However, I suggest that if you want to hang the sun cube in your backpack to charge while walking or when the charging site is often bumpy, It is better to thread the two solar panels with ropes or fix them in one position to prevent the suction from being shaken off due to vibration and losing the function of charging
The assembling magnetic attraction of the sun cube itself is very good. After all, there are corresponding docking holes. But if two or more sun cubes are connected in series or parallel, because there is no corresponding connecting hole at the edge, the connecting part can only be connected by the magnetic attraction point at the edge, and the attraction is relatively weak, which is easy to be separated due to vibration These are two solar absorbers, which can be overlapped and adsorbed together when folded. The volume is slightly larger than the checkbook when folded. At this time, the solar cube does not have the charging function. Only when two solar absorbers are pulled out and spliced into a square solar charging panel can it have the charging function Take a look at this half of the sun cube with LCD. The LCD screen is simple and can display the current status in real time so that you can always know the charging status. Another feature of the Sun Cube is that it has an automatic reset function, that is, it can be charged normally under normal sunlight conditions, and it can be automatically reset without plugging when the sunlight conditions are restored, such as charging is disconnected when the light is blocked or there is no light. The sun cube is very strict with the light. If you are indoors, no matter you turn on all the lights or even use the strong lights, it cannot be charged through the light. It can only be charged when you take the sun cube outside in the sun. It is a little inconvenient for this pen. If you can also use it indoors, it will be more humanistic The yellow parts on the alloy frame are magnetic absorption points. There are 16 such magnetic absorption points in the sun cube. There is a small hole in the four corners of the solar absorption panel for external use Change the position of the left and right small light absorbers of the sun cube to simulate the parallel connection of two sun cubes. Through observation, it is found that the connection suction is slightly weak, and it is easy to separate the two solar light absorbers with a little more force After taking back the sun cube, it is not very large, and can be mastered by one hand. It is still within the acceptable range On the right of the figure below is the author's LeEco MAX2 The 5.7 inch narrow edge mobile phone has the same volume as the 5.5 inch iPhone 7 plus. It can be seen from the comparison that the Sun Cube is larger than the author's mobile phone, but within the acceptable range It's still no problem to put the sun cube in your pocket. It's very convenient to carry Trial demonstration
The sun cube can only be charged in outdoor sunlight. First, test its charging performance. Its operating temperature is between - 40 ℃ and 65 ℃, which is enough to cope with most outdoor environments. With its self-developed power management chip MPPT enhanced power tracking technology chip, its charging efficiency can be greatly improved. The temperature of the day is very high and the sun is very strong, The sun cube was exposed to the sun for about ten minutes, charging the mobile power supply, and everything worked normally
When the mobile power supply is connected for charging in sufficient sunlight, the LCD display shows that the output current is 0.25A. Before parallel connection, the maximum output current of a single sun cube is 0.9A. This time, the output current under strong sunlight is far from the advertised 0.9A Disassemble the sun cube and use half of the charging board to charge it. The LCD screen displays an output current of 0.18A. It can be inferred that the sun cube composed of two solar absorbers is a group of parallel connections, and the current provided by a single absorber is not large Let's try to charge the mobile phone again. The model of my mobile phone is LeEco MAX 2. The battery capacity is 3100 mAh. After readjusting the sun cube, the LCD shows that the current output is 0.22A, which is equivalent to the charging current output of the previous mobile power supply. During use, the current output will change with the change of light or slight movement Fold the sun cube and charge the phone, The current output of the LCD screen is displayed as 0A. After several attempts, the results are the same. It seems that the Sun Cube will be more stable when used in combination. In fact, it is just a small test to disassemble the Sun Cube for charging. The results show that electronic devices with high requirements for current output must be used in combination to charge normally. summary
China Aerospace Solar Mobile Power Supply - Sun Cube personally feels it is very practical, especially when you go hiking, hiking and a series of sports, it can provide you with endless power supply. If you encounter a sudden disaster, it can show its importance, and its size is not large enough to be carried easily in your pants pocket, It is a good companion for home travel. At the same time, it uses environment-friendly energy. From the perspective of environmental protection, it will not pollute the environment. If solar energy can be widely used, the environmental pollution of our planet will be greatly improved. This sun cube is outstanding both in size and function, but during the trial process, I have some suggestions to improve: The idea of magnetic suction is very good, but actually it is hung on the backpack for charging, so it is still afraid that the action is too big to cause the risk of falling; and As it is made of hard solar panel, it is easy to be damaged when falling to the ground.
The advanced design of outstanding products has made today's Sun Cube, and we expect the next generation of Sun Cube to have more outstanding performance, make greater contributions to our healthy life and promote our environmental protection cause.
