In normal holidays, there are often travel and outdoor activities arranged. In order to ensure the sufficient power of mobile phones, cameras, etc., I will take a charging bank with me. If there is power supply in the city, it can basically meet the power demand. However, if it is in the mountains where power is difficult to use, or in the daytime when power consumption is high and power is urgently needed, or even when there is no external power supply for several days, how to ensure power consumption.

The concept of converting new energy sources such as solar energy and wind energy into electric energy has been implemented for many years. This kind of energy from nature can be applied to our life, which has its unique advantages. In recent years, solar power charging treasure has gradually entered the market. We are lucky to have the opportunity to experience the "Solar Cube" of China Aerospace Solar Mobile Power Supply. Let's take a look at the actual use effect of this solar power charger.

First, let's have a visual experience of the previous video.

1、 Unpacking

Like the packing box of a book, there is a description of the product features on the front. The "China Aerospace" in the upper right corner is an honorable product. With the support of aerospace technology, the quality must be good.

The specification parameters are on the back of the packing box.

The product specifications are as follows:

Size: 190 * 105 * 9.5mm

Power: 5W

Output voltage: 5.2V

Maximum output current: 0.9A

Maximum output voltage of multiple sets in series: 20V

When I opened the box, the sun cube reinforced with foam felt very small at first sight, just like the size of a long wallet. There is also a manual for this product.

2、 Product details

Imported Kevlar backplane, 3mm alloy frame, native gold and black color matching, tall and tall.

Different from other solar panels on the market, this solar cube is small, light and thin, a little larger than the mobile phone, as thick as the mobile phone, and weighs only 208g.

There are small grid like lines on the front smooth panel, and the golden "China Aerospace" in the middle is particularly eye-catching.

Manufacturer and product model are on the back.

This solar cube is made by splicing two solar panels. It uses a magnetic socket to connect the cells in series/parallel.

Flip over and transform into a splice.

The solar panel with frosted surface can increase the friction force and make it more stable to take.

At the four corners of each panel, there is a common hanging hole.

There are two magnetic sockets on three sides of each panel, which can realize series parallel expansion of multiple battery panels.

There is a green LCD in the middle, which can display the current in real time.

There are not too many switch keys outside, only a power output USB interface.

3、 Experience

This sun cube is super thin and portable, which is very convenient to carry out.

When the solar panel faces the sun, the LCD screen displays "0.00A", which means that the reset is completed and the charging equipment can be connected.

After the device is connected, the LCD screen displays the current in real time.

In order to achieve the best charging effect, adjust the position and direction of the solar panel until the current display value is maximum.

The efficient power management chip is used internally. MPPT strengthens the power tracking technology, reduces the power loss in the circuit, improves the solar energy conversion rate per unit area, and significantly improves the charging efficiency as much as twice the output power of ordinary solar panels.

The automatic reset function of the sun cube can avoid repeated plug and pull operations caused by the temporary blocking of solar energy or the interruption of charging due to the change of light. This thoughtful design can extend the battery life of charging equipment.

The solar charging panel depends entirely on the intensity of sunlight. A certain charging effect can be achieved only when the light conditions are continuous. It was a sunny day in Beijing in September, at 12 o'clock at noon, and there was no shelter. The current pulsation of the LCD screen was between 0.5A and 0.7A. After 20 minutes of charging, the power of the mobile phone increases by 2%. At this charging speed, it takes about 1000 minutes to fully charge 100%, which is 16 hours. I can't afford to wait.

When the solar panel works, the temperature will rise. However, the solar panel is very hot due to the direct sunlight at noon. In order to measure the heating condition of the solar panel itself, take it to a relatively cool place, avoid direct sunlight, and the current display is about 0.10A. After charging for half an hour, measure the temperature of the outside air at 35.4 ℃ and the solar panel at 37.2 ℃. It seems that the temperature rise is not obvious. After all, the charging current is not large.

This solar cube can also be used for series parallel combination of multiple solar panels like the magic cube. Through the magic magnetic attraction technology of the sun cube, multiple solar panels are connected in series and parallel to meet the use requirements of more equipment. The maximum series connection is 20V, the maximum parallel connection is 10W, and the maximum current is 1.8A. Moreover, output from any USB port can realize simultaneous charging of multiple charging devices. Because there is no extra battery board, we can only borrow official pictures.

The combination of series and parallel connection can be used for more USB charging electronic devices, such as backup batteries, flashlights, mobile phones, tablets, etc.

The outdoor activities during the holiday, with the sun cube, are really convenient to carry, at least not heavy, and will not burden the travel. When you travel outdoors, you encounter a shower. Raindrops accidentally splash onto the solar panel. Wipe off the rain with a paper towel. The solar panel will not easily penetrate into the rain. However, the effect of receiving sunlight is not obvious on cloudy days or with obstructions.

However, since the solar panel is connected by a magnetic socket, the magnetic disconnection and the falling off of another panel may occur when the solar panel is moved or touched by the outside. Therefore, special attention should be paid to the use of the solar panel.

It is recommended to temporarily meet the charging needs of electronic equipment under sufficient sunlight.

4、 Summary

Integrating the quality of China Aerospace, the interior uses efficient power management chips, alloy frames, Kevlar backplane, ultra-thin portability, and the appearance design of solar panels is really commendable. Power failure automatically resets. After the power failure due to unstable lighting, it does not need to be plugged in and out. It automatically stops starting charging. The magnetic suction interface can be used to improve the output capacity of multiple blocks in series and parallel.

However, the dependence of solar charging panels on sunlight is too high, coupled with the limitation of the area of solar panels receiving sunlight, which cannot achieve the charging effect of external power supply. Throughout the current market, most of the relevant solar charging products have the problem of limited power. Therefore, the solar power charging bank cannot be relied on too much. It is recommended to use it in a temporary emergency.
