Recently, a new word has appeared on many social platforms, which is called the never power-off rechargeable treasure. So, it reminds me of the hand powered machine 10 years ago. I didn't expect that many years later, this "new word" came out again, but this time it is smaller in size. However, it is still inseparable from the principle of "shaking", which is said by smart friends, I can't play with my mobile phone with one hand and shake it with one hand. In order to charge my mobile phone, should I shake my hand?

For this problem, cough Cough, In fact, the principle of shaking the power bank is based on manual operation to achieve the purpose of rotating the internal magnetic rotor and convert it into electric energy. Whether to shake off the residual or not depends on how you look at this topic. This is a constant power bank that needs to be "shaken". So, is there any power bank that does not need to be shaken? The answer is yes. What I want to share with you today is a new generation of never power-off charging treasure, the sun cube, a solar mobile power that can be freely spliced.

When it comes to the word solar energy, I believe everyone will not feel strange. The most common one is the street lights in the city streets, and the solar water heater in our family. So, a mobile power supply can also solar energy. What's the matter? Not to mention, this is a magic cube of the sun produced by China Aerospace. It seems that all kinds of tall technologies bring surprises in actual use. Let's experience it together.

The Sun Cube is a new generation of portable solar mobile charging product, which integrates the core technology of power management of China Aerospace, and greatly improves the solar energy conversion rate per unit area. To put it simply, where there is light, there is power. From the appearance, it is very compact. The 3mm alloy frame is compared with the imported Kevlar backplane, It is a little bigger than the mobile phones in our daily life, so carrying it won't take up too much space.

There is no need to worry about the volume. The sun cube has a small and thin design. When we use it, we can open it, and when we store it, we can combine it. The magnetic suction scheme is adopted, so it is very convenient for us to carry. The 3mm alloy frame adopts the spray frosting process, which is comfortable to hold in the hand. The whole battery panel is only 210g.

The power management chip independently developed by Sun Cube and the oil MPPT enhanced power tracking technology can reduce the power loss in the circuit, and to some extent, greatly improve the solar energy conversion rate per unit area.  

The charging efficiency has also been greatly improved, which is equivalent to twice the output power of ordinary solar panels. The official website said that it takes 2.5 hours to fully charge the iPhone 7 under good lighting conditions. In the test, we will use a Glory 9 mobile phone with 32% remaining power and about 1 hour of full charge.  

Not only that, the sun cube also has an automatic reset function to avoid repeated plug and pull operations caused by temporary solar occlusion or lighting changes, and the resulting BUG has also been effectively solved. It can also display the current charging status in real time on the cube, because here it is equipped with an LCD display screen, which can effectively improve our search for the best charging position and direction, Instead of blindly throwing it away.

The magic cube of the sun also has a powerful trump card, that is, multiple magic cubes can be used. Through the magic magnetic attraction technology of the magic cube of the sun, multiple solar panels can be connected in parallel and in series to meet the use requirements of more equipment. The maximum series connection voltage is 20V, the maximum parallel connection voltage is 10W, and the maximum current can reach 1.8A. Since I have only one Rubik's Cube, the specific data cannot be shown here.

For the safety of users, the sun cube will not be discounted in the high temperature environment. When the solar cell works, its temperature will be higher than the ambient temperature. However, the working voltage of the solar cell will decrease with the increase of temperature, generally about - 3mV/° C. If the step-down mode is used to provide 5.3V output, 12 units are required to be connected in series, and the working voltage of each unit is 550mV.  

At normal temperature, the total voltage of 12 tablets is 12X550mV=6600mV. For each degree of temperature rise, the working voltage of series connected batteries drops by 12 * 3mV=36mV; To maintain the output voltage of 5.3V, the maximum temperature rise range is (6600mV-5300mV)/36mV/° C=36.1 ° C; Therefore, the maximum operating temperature of the system in depressurization mode is 25 ° C+36.1 ° C=61.1 ° C.  

The Sun Cube is a system that works by boosting voltage. The maximum operating temperature is not limited to 70 ° C, and can reach 80 ° C in a short time. The output power has little change with temperature. (Data from the official website)

I don't think it's necessary to say much about the importance of mobile power in life. As the saying goes, "The head can be broken, the blood can flow, and the phone can't run out of power." What should we do if we open the black hole? People often pay attention to the capacity when choosing mobile power. Otherwise, the appearance of the sun cube is a safe, convenient The biggest advantage of practical mobile power for solar energy like Sun Cube is that there is power when there is light, which saves the trouble of "hand shaking". It is absolutely the first one in innovation. In contrast, I personally prefer this kind of power supply that never cuts off power.

China Aerospace Solar Mobile Power "Solar Magic Cube" is a product with excellent appearance, workmanship and performance, which can well meet our use of solar energy. We need more than just a mobile power supply, but more in terms of practicality and environment. We believe that this mobile power supply will be more popular with users. However, It's a bit awkward without the sun. We all know that you can't have both fish and bear's paw. Although there is no satisfaction in the sun, there are very few indoor environments where we use mobile power. Personally, I think the sun cube gives a thorough interpretation of the "safety" of mobile power. The most important thing is solar energy.
