For ordinary outdoor sports enthusiasts, the battery life of mobile phones and other electronic products is basically supported by charging treasure. However, for high-level outdoor sports such as camping and traversing, the weight bearing problem of the power pack makes it unable to meet the use requirements. The power pack is certainly not the best choice. Now let's introduce a solar mobile power supply "Solar Magic Cube" for China Aerospace, which is a solar portable mobile charging product, integrating the core technology of power management of China Aerospace, and greatly improving the conversion rate of solar energy per unit area.

The package of the Sun Cube is relatively simple. The surface details the characteristics and design of the product, and the words "Honorable Product of China Aerospace" in the upper right corner are particularly conspicuous.

Open the package, there is only a manual and the sun cube inside the box. The content of the manual is too simple, focusing on the series and parallel use of the product. I almost broke two solar panels because I didn't read the instructions carefully. I stopped my wrong behavior after I found something wrong. Fortunately, the solar panel material has good toughness.

The sun cube consists of two solar panels. From the appearance, the imported Kevlar backplane is not only fashionable, but also lightweight. The 3mm gold alloy frame gives the product a strong local flavor. The folding size is 192 * 107 * 95mm, slightly larger than the iPhone 7 Plus, and the product weighs about 210g. This weight is more than 40g lighter than my lightest 10000mAh Yubo Power Bank, which shows that it has certain advantages in weight.

The Sun Cube adopts the self-developed MPPT (maximum power tracking mAh) power management chip, which can provide continuous, efficient, stable and safe solar charging services in real time. There is a small LCD current display screen on the metal frame, which is mainly used to realize real-time monitoring of charging current output and quickly adjust the position to obtain the best charging effect. The logo of China Aerospace and the brand is clearly printed in the middle of the backplane.

If you are careful enough, you can find that there is a small hole in each corner of the sun cube. This hole is mainly used to hang products for easy bundling. From the perspective of outdoor sports, this detail design is very considerate. Without these holes, it is difficult to fix and hang them on the backpack. To be exact, they can't be fixed at all. The following shows the ease of use of this hole.

Each alloy frame is equipped with such inconspicuous small things. This is the original magnetic splicing socket of the Sun Cube, which can realize the series connection and parallel connection of multiple solar panels, improve the output voltage and current, and meet the charging needs of different devices. Parallel connection is easy to imitate, and series connection is difficult to surpass. Sun Magic Cube innovatively can connect multiple solar panels in series through the magic magnetic attraction technology, with the maximum voltage of 20V, and the maximum current of 10W after parallel connection, up to 1.8A. According to my understanding of similar solar charging panel products, the charging data of Sun Cube is almost the same as that of other products, but its weight is more than 30% lighter. It seems that lightness is a major feature of Sun Cube.

The Sun Cube adopts USB power output interface, which can basically dock with most digital equipment. However, there is no charging cable attached to the product, so the user needs to equip it by himself. I'm sorry about that. When the solar panel is working, its temperature will be higher than the ambient temperature, but the working efficiency will not be affected basically when it is used at high temperature, even if the output power will not change too much at 70 ° C, it is estimated that this temperature is the extreme temperature for outdoor sports

In the past 10 years, Sun Cube has independently developed power management chips. MPPT has strengthened power tracking technology, reduced power loss in the circuit, and greatly improved the solar energy conversion rate per unit area. The charging efficiency is twice the output power of ordinary solar panels. IPhone 7 only takes 2.5 hours in good light conditions

I tried to scratch and stab the solar panel with a knife, but there were only slight scratches on the surface, no deep damage. It seems that this product is easy to adapt to harsh outdoor environment.

The weather on the day of external shooting was cloudy and overcast. Looking up at the sky, I would not feel dazzling, so I could experience the charging process at the end of the day. Three days later, I would make a supplementary test on sunny days. First, assemble the two solar panels together. When the sun shines, the LCD screen will automatically reset and display 0.00A. At this time, the charging equipment can be connected. Remember to reset before charging.

Mobile phone charging experience: the outdoor temperature is 24 ° C, the weather is sunny, and the wind is moderate. The solar panel is facing the sun, and it is used to charge the vivo Xplay6. From 2:00 p.m. to 3:00 p.m. for an hour, the total charge is 27%, about 1080mAh of electricity (the electricity of vivo Xplay6 is 4000mAh). During this period, there were several cloudy times, and this charging speed can basically reach the speed of official publicity. However, I regret that I can't try to connect multiple products in series or in parallel.

The charging experience of Huami sports watch, the outdoor temperature is 24 ° C, and the weather turns sunny to cloudy at 3:00 p.m. Accumulated charging for 30 minutes is 21%. Because cloudy weather directly affects the charging effect, the outdoor use of the sun cube has high requirements on the intensity of sunlight. The speed of sunlight will naturally be much faster, while cloudy weather is difficult to achieve the desired effect. However, the automatic reset function is very convenient in actual use, eliminating repeated plug and pull operations. I plan to experience the charging process of different products in the near future, such as mobile power and headlights, which are essential outdoor equipment for outdoor players.

The charging speed should not be compared with that of ordinary power packs. They are not the same type of products. The power bank is a power storage device, which is naturally much faster when the power is sufficient. The sun cube is an energy conversion device, which converts solar energy into electric energy. It has different properties, so it is not comparable at all. When you use it outdoors, you can easily find this kind of withered grass or dry branches. These things can take the rope to fix the sun cube on the backpack, and then connect the sun cube to the charging treasure, so that you can have a perfect endurance.

Summary:

This product can be said to be one of the necessary equipment for outdoor sports enthusiasts. Where there is light, there is electricity, which is especially suitable for outdoor workers and sports enthusiasts. It is light and sturdy, wear-resistant and durable, and has automatic reset function. The magnetic suction design can meet the charging requirements of different equipment. However, it is a pity that this product is not waterproof. After all, all kinds of harsh outdoor environment are unpredictable. I hope the next generation product can improve its waterproof function. The best charging effect will be achieved when the sun cube is combined with the mobile power supply.
