How to use solar power bank? Solar charging

The concept is good but the effect is poor. It is difficult to charge a mobile phone in the sun! "Using the world's cutting-edge light energy charging panel, it can charge for 20 minutes in the sun, and it can talk for 8 minutes; it can charge for 20 minutes under the light, and it can talk for 5 minutes. "It can be charged under the light of a candle and can continue to make calls"——Recently, advertisements for "always on, environmentally friendly solar cell phones" have appeared in some TV shopping programs and online mobile phone stores, and some domestic brand mobile phones have been equipped with " "Solar Energy Concept" is all the rage in the market. Can you really charge your phone and make calls just by basking in the sun? He Guili, director of the China Telecom Research Laboratory of the Ministry of Information Industry, made it clear to the media that the current level of technology is not enough to commercialize solar cell phone batteries. As China’s authoritative mobile phone testing agency, China Telecom has not yet received any orders. Any mobile phone manufacturer’s application for testing new solar charging mobile phone technology. Readers complained that they were deceived when buying solar-powered mobile phones. As seen in some TV direct sales programs and online stores, the price of solar-powered mobile phones ranges from 500 yuan to 1,000 yuan, and they all have the same feature of a solar panel. The solar charging device of most mobile phones is designed on the body of the mobile phone, while a few models of mobile phones adopt a design where the charging device is separated from the body. "I heard on TV that this phone can be charged directly using solar panels, so I bought it, and then I found out there was a huge difference. The seller *** gave me two battery panels, but one of them couldn't be fully charged. I couldn't make phone calls or listen to music. No, it is even more false to say that candlelight can charge. The complaint has not been resolved for a long time..." Mr. Song, a consumer, told about his experience in purchasing a certain solar-powered mobile phone. Although manufacturers make fantastic claims about "solar charging, never running out of power", however, many consumers find after getting the mobile phone that such mobile phones cannot sustain daily use by relying on sunlight or other light sources alone, and it is even difficult to turn on the phone. The manufacturer explains that the battery board is a gift from the dealer. Take the L138 and A350 mobile phones launched by a domestic mobile phone manufacturer as examples. They are both titled as "light energy mobile phones" in publicity. However, these two mobile phones currently only have two methods: TV direct sales and online ordering. Consumers cannot see the physical instructions of their products before purchasing. No introduction to these two mobile phones can be found on the official website of the group company or the official website of its mobile phone manufacturer. Regarding the statement that "everything is possible with light", the Shenzhen customer service of the "light-powered mobile phone" L138 explained: "It cannot yet achieve such an effect. It only has a photoelectric conversion function. In fact, using light energy for charging is just an emergency plan. I can make it clear I can tell you clearly that it cannot achieve the effect mentioned in the TV advertisement.” Regarding the exaggerated advertisement of its own products, customer service also said: “This advertisement depends on our dealers, and the photovoltaic cells are not. Our company's products are gifts provided by dealers. " Experts say "solar phone" is suspected of false propaganda. He Guili, director of the China Telecommunications Research Institute of the Ministry of Information Industry, said, "Solar panels can indeed generate electricity for the sake of environmental protection. The proposed 'solar mobile phone' concept is very good, but as far as I know, the current level of solar device manufacturing in our country is not enough to make a mobile phone the size of a mobile phone that can be used by solar energy alone, even under sunlight. The current generated by the battery panel is also very weak. It is very difficult to fully charge the mobile phone battery. If you want to provide enough power, you must have a large solar charging panel, but it is impossible for consumers to carry the solar panel while using the mobile phone. ?” As China’s authoritative mobile phone testing agency, China Taier Laboratory has not yet received any application from any mobile phone manufacturer to test the new solar charging mobile phone technology. He Guili said that the "solar phone" reflects the current fierce competition in the mobile phone market. In order to sell products, many businesses do not hesitate to come up with all kinds of exciting language to promote promotion. "However, if it involves false propaganda, it must be handled by the industrial and commercial department." Come and investigate." Market research: "Hand-crank charging" mobile phones are on the market again. The author went to a mobile phone chain store on Nanjing East Road. When he heard that he wanted to try a solar-powered mobile phone, the salesperson immediately said: "It is no longer sold. A certain product that has been sold for a while. But it was later discontinued. Solar charging is fake and a gimmick by the manufacturer, and it cannot be charged at all.” However, the salesperson interviewed showed another new concept of environmentally friendly mobile phone: a hand-cranked charging phone. He took out a certain domestic brand mobile phone to demonstrate in person - after quickly shaking the small hand-cranked charger, the phone displayed "charging".

He said: "This is the most primitive power generation device. Compared with solar cell phones, it can at least be charged." The concept of "hand-cranked power generation" seems to be catching up from behind. For some big-brand mobile phones that are not equipped with hand-crank chargers, merchants on Taobao have also begun to sell hand-crank charging devices. These small chargers can be put into pockets and the mobile phone can be charged by shaking the rocker. The merchants claim that " "Crank it for 3 minutes and you can make a phone call for 2-8 minutes." Some hand-crank chargers can also be used as flashlights. Some mobile phone sellers who have been complained about due to the "solar concept" have also begun to secretly replace the solar charging devices in mobile phone packaging with hand-cranked charging devices. However, the relevant departments have not yet responded to the effectiveness of hand-cranked mobile phone charging devices.
