That is, release and charge, abandon complex data lines Wireless charging has an advantage that you can abandon complex data lines, so that the desktop becomes more clean and tidy. In other words, wireless charging needs to be used in specific scenarios and fixed locations. For example, on the company desk, on the bedside table in the home bedroom, etc., and the wireless charger can also act as an ornament, perhaps many of the small partners in use are the same as I think.
Wireless charging technology still needs to continue to develop,At present, the wireless charger is really not practical, and itself is not convenient, so it needs continuous development and technical improvement.
Wireless charger is often not attached, but need to buy additional, so for many people, spend a few hundred yuan to buy a charging base is often not very cost-effective, and sometimes a charging base is difficult to reflect the real portability of wireless charging, often need to buy more than one, buy one or more at home, put one in the car, The company buys another one, and the manufacturer's own wireless charger is often not cheap.
I'm using a stand wireless charger and carLoaded wireless charger. One is put on the desk, one is put on the car, and the electricity can be added at any time, which is very convenient. Say no one uses the electronics factory workers! People who sit in the office like wireless charging, and they put it in the company every day and pick it up when there is news. The charge is slow, but the whole day is full. The staff of the Communications Department of the Ministry of Industry and Information Technology said that it is inevitable that the wireless charger has radiation, but since it has been listed, it means that it must meet international standards and will not cause great harm to the human body. For this view, He Guili, director of the Tel Laboratory of the Telecommunication Research Institute of the Ministry of Industry and Information Technology, agreed: "NoAs long as the line charger is done in accordance with the technical specifications, there will be no radiation hazard to the human body." But there is a key problem.
1, the hotel is not necessary to provide guests with wireless charging services. To take a step back, even if the hotel has a wireless charger, it is usually only possible to 5W standard slow charge, to charge the phone for seven or eight hours, some guests may be from the hotel to check out of the totalAlso live for more than ten hours, such charging efficiency is obviously not suitable for a tight travel environment. Although many public places now provide charging functions, there are few places that support wireless charging. 2, wireless charger is good, pros and cons are as follows: Advantages: In order to improve the unity of the mobile phone now most mobile phones are no longer with the headphone hole this design, but many users said that the headphone hole design is not humanized. But with the wireless charger, we can directly put the mobile phone on it, bring headphones to listen to music, but only limited to listening to music, want to play games that is not realistic. <3, because the transmission distance is very close, to achieve charging, you must put the device to be charged close to the charger in order to charge. After that, it doesn't work. The current wireless charging is low voltage, commonly used on mobile phones, low voltage, safe voltage, there is no danger of electric shock. Therefore, based on the close distance and safe low voltage, wireless charging is safe and there is no risk of electric shock.
4, that is for sure, the phone must support wireless charging, in order to use. It doesn't help if you don't support it.
5, wireless charging hurt mobile phone? Wireless chargerUnder normal circumstances, it will not harm the mobile phone, and the working frequency of wireless charging is now below 1M, so it will not affect the signal of the mobile phone. At present, most mobile phones on the market are in line with the QI wireless charging standard, with a built-in wireless receiver, which has a rated voltage and current, so the wireless charger has no effect on the mobile phone.
6, useful ah! Daily visible mobile phones and sophisticated algorithms, the whole version has no electromagnetic radiation, and there will be no energy loss. The lightweight Energy Square can be placed anywhere without wires and is clean and tidy. The road can be developed laterThe rise of line charging has led to discussions about electromagnetic radiation.
2, for the human body: wireless charging technology is harmless to the human body. The resonance principle used by wireless charging is magnetic field resonance, which is transmitted only between coils resonating at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
3, in fact, it is certain to tell you that the harm of wireless charging to the human body is very small, almost negligible. This is just like our usual use of Wi-Fi, mobile phones, televisions and other electronic products, andWe also do not exist between the transmitter and the receiver the radiation level is small, and the main frequency absorbed by the human body is not consistent with the charging frequency, so we can not worry about the harm of wireless charging. 4, the Ministry of Industry and Information Technology communications Department staff said that wireless chargers have radiation is inevitable, but since it has been listed, it means that it must meet international standards, will not cause great harm to the human body. For this view, He Guili, director of the Tel Laboratory of the Telecommunication Research Institute of the Ministry of Industry and Information Technology, agreed: "Wireless chargers as long as they are done in accordance with technical specifications, there will be no radiation harm to the human body." But there's one more thingThe key problem.
3, if the use of vivo mobile phone, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, willThe device that needs to be charged can be charged by contact with a powered wireless charger.
4, boot charging, do not carry out any mobile phone operation will not affect the life of the mobile phone. But if you make phone calls or send text messages, it can cause damage to the phone, people and batteries. The voltage of the mobile phone when charging is higher than the standby, if the operation such as receiving and making calls at the same time, the instantaneous voltage during the call or connecting to the network will be many times more than usual, which is easy to damage the sensitive and complicated parts inside the mobile phone, resulting in frequent maintenance of the mobile phone.
5, in simple terms, the so-called wireless charging is that you do not need to contact the wireFor charging, mobile phones that support wireless charging can be put and charged on the wireless charger. Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Wireless charging of mobile phones mostly uses the principle of electromagnetic induction.
1, radiation will certainly have, but without the current space charging, there is no evidence that there will be damage to the body radiation standard and space area relationship. According to internationalThe safe limit set by the Non-Ionizing Radiation Research Committee is 10 watts per square meter. According to the calculation of 90 square meters of family housing, residents can withstand the maximum radiation power of about 900 watts. 2, the space charging technology is actually a kind of electromagnetic radiation charging, so there is still a certain amount of radiation, at least relative to the ordinary data line charging, the radiation will be much larger, but the level of this radiation should not be able to affect the degree of human health otherwise it will not be approved for market.
3, all wirelessly connected electronic devices will emit electromagnetic radiation, butA large number of measurements indicate that wireless charging produces relatively little radiation. "As long as wireless chargers are manufactured in accordance with technical specifications, they will not cause radiation damage to the human body," said an expert from the Telecommunication Research Institute of the Ministry of Industry and Information Technology. .
