Many people often come into contact with mobile phones when their phones are out of power or have insufficient voltage. There are no such scenes when they take pictures. Friends who are particularly fond of outdoor sports do not have power in the field, making mobile phones a blind spot for information exchange. As a new type of energy, solar energy has the advantage of being green and clean, free of environmental pollution, and inexhaustible with no geographical restrictions, and its application has become increasingly widespread. The solar charger converts light energy into electricity and can be used to charge mobile phones, digital cameras, MP3-MP4, iPAD and other small appliances anytime and anywhere. It is a must-have for travelers, business travelers, outdoor sports professionals, and business workers. companion. However, solar chargers have not been popularized. The reason for this is that because of their low conversion efficiency and slow charging speed, they are abandoned by everyone.
In fact, the efficiency of solar charging devices is not low, and now many areas are using solar energy to provide clean energy. The main reason is that the area of ​​solar panels we use is too small, but if the volume is too large, the portability Is a problem, so portable solar charger can not be considered in terms of area, need to consider is a new type of solar panel material, improve conversion efficiency is the key. Gu Sheng digital solar charger uses the United States imported the third generation of SUNPOWER® high-sensitivity solar energy The board, the conversion efficiency of up to 24.2%, compared to the conversion efficiency of ordinary solar panels increased to 200%, which means that can bring faster charging speed.
Gu Sheng solar charger shape and ordinary solar charger is not much difference, folding storage design, convenient outdoor use. The size after storage is similar to that of a 9.7-inch iPAD, and weighs only 598 grams. Use waterproof fabric design, waterproof level can reach IPX4.
Gu Sheng solar charger is characterized by the use of a digital voltage regulator box, dual USB output, output port has a waterproof plug design, the maximum current of a single USB port can reach 2.4A, dual USB port output rated up to 4.5A, to prevent the current High damage equipment. And digital display can always grasp the charging voltage, if the display voltage is too low, you can properly adjust the angle of the solar charger to ensure fast charging.
Although the charger is also designed with a storage bag, but its design is lacking, and now the mobile phone screen is 5.5 mainstream size, storage bag apparently did not take into account the length of the phone after inserting the data line, resulting in smaller size of the storage bag, the phone can not Into the scene, in fact, manufacturers only need to open a small window at the bottom of the storage bag can be solved, and hope to be improved in later versions.
The factory has two quick-connects for each solar charger, and a hanging ring is also designed on the solar panel to facilitate the user to hang the charger on the backpack when walking outdoors, but the charger is in the process of moving. The effect of the charging effect is not good when it is not in a static state. If the condition is still, it is better to keep the charger stationary.
Gusheng Solar Charger uses waterproof material on the outer layer, waterproof grade can reach IPX4 level, that is to say that the liquid splashed from the shell in any direction will not have harmful effects, which is the so-called splash water. But it will not rain. Out of the sun, so this does not have to be entangled.
Closer to home, solar chargers are charged under the same conditions, consumers are not only able to charge, but also faster. Then I will release several test results to everyone, but the test data is only for reference.
Environment: Outdoor
Temperature: 33 degrees
sunny
Elevation: 740 meters
Time: 18:00 - 15:00, August 28, 2017
Equipment: Charm Blue Smartphone
Note: The mobile phone should be placed as far away as possible from the sun, because in the process of charging the mobile phone under the sun's irradiation, it is easy to heat, some mobile phones will start overheat protection, stop charging, to prevent the battery from overheating and explosion hazards.
Test using the manufacturer's standard data cable, using the USB voltage and current meter for recording, charging time of 1 hour, charging current 0.5A, output power of 483 mA, and the manufacturer's promotional data is not a bit, very disappointed. In the afternoon, we called Gusheng to consult. The feedback from the manufacturer may be a problem with the data line. It is recommended that the original data line be replaced before testing.
Environment: Outdoor
Temperature: 32 degrees
sunny
Elevation: 740 meters
Time: 13:00-15:00, August 29, 2017
Equipment: IPAD tablet
Because the original data line of the mobile phone could not be found, the second test used an IPAD tablet and used the original data line for charging. Charging time is still 1 hour, the charging location and the test time remain the same, but the charging efficiency of this test is very good, a total of 2028 mA output in one hour, more than four times the previous day, and the average charge current has been At about 1.7 amps, the highest is 1.8 amps and the lowest is 1.4 amps. A lot higher than the 0.5 a day before, it seems that the data line has played a very important role.
Environment: Outdoor
Temperature: 29 degrees
sunny
Altitude: 760 meters
Time: 9:30 AM, August 30, 2017
Equipment: 360 Smartphone
The test time was chosen at 9:00 am, test time was 30 minutes, the original data line of the 360 ​​mobile phone was used, the charging current was 1.3A, the output power was 722 mA, the 360 ​​mobile phone was a 5000 mAh battery, and the mobile phone power was from 74% to 83%, the actual charge into 500 mA. Test results are very satisfactory. Visible the importance of the original data line, the manufacturer's standard in the data line is simply digging yourself to jump, not as good as not.
Environment: Indoor balcony
Temperature: 30 degrees
sunny
Elevation: 780 meters
Time: 8 a.m. to 12 p.m. on August 31, 2017
Equipment: 360 Smartphone
This time, the test site was selected on the indoor balcony. The sunlight irradiates the solar energy charging plate after passing through the glass. However, the test result is not ideal. The current in one hour is always 0.1. Since the current is too small, the charging is intermittent. Can't charge the phone.
The effect of the first indoor test was unsatisfactory. Was it because of the morning's cause that the intensity of light irradiation was too low? Therefore, the second indoor test was conducted. This time was chosen between 10:45 am and 11:15 am. The sunshine was at midday after midday. However, after one hour of testing, the current reached 0.3 am. . It seems that the charging efficiency of solar chargers through glass is much lower.
The fifth test:
Environment: Outdoor backpack on the move
Temperature: 30 degrees
sunny
Elevation: 830 meters
Time: 10:00 - 12:00, September 1, 2017
Equipment: 360 Smartphone
This time, the solar charging board was hung on the backpack. During the test on the move, it took about 1 hour and 15 minutes on foot, but the battery power was finally checked. It was only charged at 6%, about 300 milliamps, and it seems that the charging was on the move. The effect is not very good either, because the solar charging board can't always shine in the sun while walking. Sometimes there is no sun in the shade, so the charging effect is not ideal.
Test summary:
After more than 10 days of test use, I have the following summary of this Valley Sheng digital solar charger:
1. The sun is better than no sun
2. Outdoor is better than indoor, do not use glass;
3. The data line quality is very important, the original factory is the best;
4. Static is better than moving.
Although many tests failed to reach the publicity effect of the manufacturers, but considering that it has entered the autumn season, the light intensity is not the strongest season of the year, so the test results are satisfactory. However, considering the solar charger Characteristics, feeling is not suitable for outdoor long-term use on foot, after all, need to rely on the weather to eat, and charging efficiency in the mobile is not good. If this if built a 10,000 mAh lithium battery, daytime hung on a backpack to charge at night Charging the device, I think the effect will be better,
