Not practical.
The conversion of light energy into electrical energy and the conversion of electrical energy into electrical energy are completely incomparable. As for current solar products, their electrical energy conversion rate is about 15% on average. Likewise, the efficiency of light charging is much lower than that of in-line charging. In other words, most solar charging concepts are superfluous functions and have no real use value.
How about a solar power bank?
It's not easy to use.
1. At present, the electrical energy conversion rate of solar products is about 15% on average, which means that when a solar panel absorbs 1,000 watts of energy
converted is theoretically about 150 watts, and the principle is that the quality of the conversion equipment is qualified. "Experts point out that under the light distraight from the sun at noon, the energy available for each square meter of solar panels is approximately 1,000 watts. 2. This piece of solar energy on the solar charging surface The panel area is about 0.0089 square meters, which means it takes about 80 hours of strong midday sun to fully charge the solar panel from the power bank. This means that if you are in Chengdu, the sunshine is not very sufficient.
In certain areas or under public lighting conditions. and the LED lights mentioned in the slogan, the time required for a full charge is ten times or even a hundred times longer. Industry insiders told reporters after calculation: "It is estimated that it will take about 100 days." to fully recharge the 200 mAh battery in Chengdu! "
2. The impact of heavy objects may cause short circuit and spontaneous combustion, the case is not flame retardant, the capacitypower is incorrectly indicated and the output voltage is too low or too high. battery is extremely dangerous

However, mobile solar power can only be used in an emergency. needs to be used for a long time in daily life, mobile solar power cannot be fully reliable when charging a mobile phone, it is recommended to choose a solar panel with a capacity of more than 0.7W , otherwise he won't have one. any obvious charging effect.
What should you pay attention to when using mobile solar power? First of allrd, pay attention to using under strong light. When charging the mobile power, please do not charge it. at least 8 hours before the battery is fully charged. As we all know, it is always difficult to expose the mobile power to direct sunlight for more than eight hours a day in the car where the temperature is high, otherwise the battery life is reduced. will be shortened. Try not to charge the mobile power through sunlight through the glass, because the effect is not obvious. Finally, the mobile power supply must be charged under strong light and cannot be used to wipe products. /p>
Although the term solar power bank is no longer a new term nowadays, it has Lithium power banks have their own advantages and are widely used by a large number of mobile phone users. However, power suppliesMobile phones still mainly rely on novelty to attract people's attention, and the advantages are not obvious from a current practical and technical point of view, the quality is very average, the charging speed is slow, and the charging rate is power conversion. is weak. Therefore, smartphone users are recommended to choose high-quality, fast-charging and safe branded power banks such as Sino to charge their phones for the entire battery life.
Question 2: Is the solar power bank easy to use? The charging principle of mobile solar power is to convert the sun's energy into electric energy and store it in the battery of the mobile solar power. When the mobile phone does not have enough power, the mobile solar power supplies the battery power to the mobile phone. However, mobile solar powere can only be used in emergencies, and cell phone charging cannot depend entirely on mobile solar power. If you need to use a solar power bank to charge your mobile phone for a long time in daily life, it is recommended to choose a solar panel of more than 0.7W, otherwise it will not have a charging effect. obvious load.
What should you pay attention to when using a solar power bank? First of all, please note that when charging the mobile power under strong light, do not delay. It must be charged for at least 8 hours before the battery is fully charged. As we all know, it is still a bit difficult to get uninterrupted direct sunlight for more than eight hours a day. Second, do not place the mobile power supply in a car where the temperature is high, otherwise the battery life will be reduced.e will be shortened. Try not to charge the mobile power by shining sunlight through the glass, because the effect is not obvious. Finally, be sure to charge the power bank under bright light and do not use chemicals to wipe the product.
Although the term solar power bank is no longer a new term nowadays, it has its own advantages over lithium battery power banks and is also widely used by a large number of mobile phone users. However, mobile solar power supplies still mainly rely on novelty to attract people's attention, and the advantages are not obvious from a current practical and technical point of view, the quality is very average, the charging speed is slow and power conversion rate. is weak. Therefore, smartphone users are recommended to choose power banksHigh-quality, fast-charging and safe brand entation, such as Sino, to charge their phone for the entire battery life.
Are you satisfied with the answers above?
Question 3: What is the quality of solar power banks sold online? It is recommended not to buy solar power banks online casually. Not only have some power banks not passed the quality inspection, but the panel area is generally small and the power generation efficiency is extremely low. Choosing a solar power bank mainly depends on the following factors: 1. Look for the brand. Branded products usually undergo strict quality inspection before leaving the factory to ensure quality. 2. The surface area of the solar panel should be large, preferably multiple. Same Charging is faster in certain conditions; 3. CapacityBattery size should be selected based on your own usage. I currently use a brand from Taidianbao. The power of the battery panel is more than 7W. It can be fully charged in 4-6 hours in normal weather, which means it can be fully charged in one day. a high-end and practical solar energy product.Products, you can pay attention to it!
Question 4: What about solar power bank? 10 points recommend buying Huangming Quad Power Bank. We made it ourselves and won the gold design award. bank in the market. Wafer silicon is beautiful to look at but useless. You can go to the official website of Huangming Solar to take a look.
Question 5: What about solar power bank? Who used it? Solar energy is becoming more and more known and recognized by people, because withreducing polluting energy sources like oil and coal, solar energy is now integrated into everything in life, such as: power banks, hats, flashlights, backpacks hand, car accessories The combination will give future generations full of hope.
Question 6: Are solar power banks good or bad? We cannot generalize whether solar power banks are good or bad. It is recommended not to just buy random brands online. It is better to buy branded ones. General solar power banks have not undergone strict quality inspection before leaving the factory, and their service life cannot be guaranteed. Second, some power banks have small photovoltaic panels and cannot be fully charged. Therefore, you should choose a solar power bank. a bigsurface of photovoltaic panels, preferably with a big discount Yes, it saves space and recharges quickly. As for the battery capacity, it should be selected according to your actual needs. I use a Taidianbao multi-ply, which can be fully charged in one day, I think it is a very good product.
Question 7: Is solar power bank useful or practical?
The conversion of light energy into electrical energy and the conversion of electrical energy into electrical energy are completely incomparable.

In other words, most solar charging concepts are superfluous functions and have no real use value.
Question 8: The energy bankie solar is really reliable or not?
Regarding the current energy conversion of small solar panels
And high cost
Compared to ordinary charging, this is not cost-effective
I hope to adopt it
Question 9: Mobile solar power supply From the perspective of environmental protection green, mobile solar power is still good, but it is not very useful and can only be used in an emergency. Since solar batteries have high lighting requirements and generally require sufficient light throughout the day, they cannot even be used in rainy areas. Compared with ordinary rechargeable power banks, they rely on light energy to charge and are slower. Consumers are not recommended to purchase this type of mobile power supply.
