This article to talk to you about Guangzhou high wireless mobile phone charging useful, as well as Guangzhou mobile phone scan code wireless charging corresponding knowledge points, I hope to help you, don't forget to collect the site oh. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, Mobile phone wireless charging is reliable
1, the power is relatively low, the current Qi standard stipulates the power in 5w, 5w, 10w and 15w power, compared with the wired fast charge 18w, 48w and other high-power chargers is still too low, resulting in the wireless charger to charge the mobile phone slowly.
2, can be taken at any time, now our data cable charging is still not very convenient, wireless charging has such an advantage, take away at any time to charge, do not need to go through unplugging the data cable and plug in the data cable such links, so at this point can also be counted as an advantage. Disadvantages: The charging speed is relatively slow. In the era of fast mobile phone charging, wireless charging is very slow.
3, simple the kind of stuff on your picture, if there is no other accessories, basically, not reliable, do not try. Related knowledge: The principle of wireless charging is very simple, using the most basic electromagnetic conversionThe principle is that a changing magnetic field produces an electric field.
4, the current wireless charging technology has been very mature, as long as the brand is reliable, basically will not explode this situation. Cell phone batteries don't break down as easily as they did in the past. With the popularity of wireless functions of smart phones, the trend of wireless chargers in the future is bound to be multi-device multi-function, which will result in a lot of similar three-in-one six-in-one or even more wireless chargers.
5, feel this technology is a chicken rib, not very reliable. The following is the Nokia 920 English manual about wireless chargingIn charging, the charger and the charged device do not need direct contact, easy to use, strong environmental adaptability, avoiding the physical interface so there will be no interface wear, sparks, leakage and other problems, in addition, wireless charging can also achieve high voltage, high current, high power charging. The cable is charged. Wireless charging also requires a wired charger, but also more wireless charging board.
3, benefit one: reduce the loss. As we all know, when using wireless charging, you only need to connect the wireless charging board to the power supply, and then place the device that supports wireless charging on the wireless charging board. Although wireless charging still requires a power connection, it can reduce the data lineThe use of the data line to avoid a large amount of loss and waste, relatively speaking, is a relatively environmentally friendly charging method. Benefit 2: high adaptation rate.
4, the biggest advantage of wireless charging is convenient. Wireless charging has little impact on mobile phones, but when all electronic products support wireless charging, the convenience brought to users is more interesting. Apple says future models of AirPods wireless headphones will come with AirPower-enabled charging cases, so users can charge them simply by placing them on a charging pad. Wireless charging helps improve safety.
1, for mobile phones, the current wireless charging is to save the use of mobile phone sockets, charging lines. The current wireless charging of mobile phones is like using an induction cooker, the pot itself does not use wires, and it can be used only when it is attached to the stove. The charging base is too far away to charge the phone. General mobile phone socket and negative charging, data transmission function, often used, the socket is easy to loose, aging, resulting in the use of mobile phone obstacles.
2, so this reverse charging technology is still very useful.We all know that notebooks can use data lines to charge mobile phones, but notebooks with wireless charging methods to charge mobile phones, is definitely a new technological innovation, although we do not know the principle of this technology, but we have found that this is a new road.
3, wireless charging is meaningful, is less inserted in the head, what transmission is no line transmission good, if you can not accept the chin or bangs do not have to consider.
4, only the current wireless charging technology is not very mature, mature can be wireless transmission of electrical energy like the wireless transmission of anti-gravity applicationsThese are the problems that physicists want to solve now. In fact, society as a whole is progressing, and some things that seem unintelligible now may be OK in a few years, just like who would have thought about what life is like now before there is no electricity. I hope it was helpful.
1, reduce interface loss: I have used 6p to 8p, obviously can feel the resistance at the interface of 8P, should be waterproof characteristics. Water resistance diminishes with use. Generally use wireless charging, reduce the drag line to play mobile phones, pick upThere will be much less mouth loss.
2. Wireless charging helps improve safety. Using wireless charging means users don't have to connect their iPhone to an unknown cable, which is where all the malicious stuff hides. Placing an iPhone on a charging pad should be safe -- unless a hacker develops a malicious device that uses wireless charging, which so far doesn't exist.
3, benefit one: reduce the loss. As we all know, when using wireless charging, you only need to connect the wireless charging board to the power supply, and then place the device that supports wireless charging on the wireless charging board. Although wireless charging still needs to be connected to the power supply, it can reduce the use of data lines and avoid a large amount of loss and waste of data lines, which is relatively an environmentally friendly charging method. Benefit 2: high adaptation rate.
4, first of all, when wireless charging, the mobile phone needs to be adsorbed on the charging base, and can not move freely, causing a certain constraint to the user. Secondly, the price of wireless chargers is generally higher than that of traditional wired chargers. The principle of wireless chargers requires the receiving device to be equipped with power conversion electronics, and both need to be equipped with coils, and also need high frequency wave circuits to meet electromagnetic compatibility, resulting in aBen Higher. Finally, wireless chargers are less efficient.
5, this system can be widely used in the future, such as charging areas for electric vehicles and power transmission for computer chips. A charging system developed using this technology would require only one hundred and fifty times the current charging time. The core chip is one of the difficulties in the application of wireless charging technology. Precise radiation range control, magnetic field frequency size, and other controls are implemented by the chip.
1Second, when using wireless chargers, if the device is not properly aligned with the charging pad or the charging distance is too far, it may lead to reduced charging efficiency, and frequent interruptions during the charging process will also cause additional burdens on the battery. Frequent charging interruptions may cause the battery to constantly re-enter the charging state, which will accelerate battery depletion in the long run. In addition, the quality of wireless chargers on the market varies.
2, 1: Reduce the loss. As we all know, when using wireless charging, you only need to connect the wireless charging board to the power supply, and then place the device that supports wireless charging on the wireless charging board. Wireless charging, though, still requires a power connectionHowever, it can reduce the use of data lines and avoid a large amount of loss and waste of data lines, which is relatively an environmentally friendly charging method. Two: high adaptation rate. Most models do not support wireless charging because of the technology and cost of wireless charging, generally low-end models do not support wireless charging, only those high-end flagships have wireless charging function. This means that only users who can afford high-end flagship have the opportunity to use wireless charging, the target group is limited, and it is still a relatively small part of the market, which cannot be popularized.
4, bound: wireless charging requires adsorptionOn the charging base, it can not be moved at will, which is more restrictive to the user than the wired charge. High price: The principle of wireless charging is different, resulting in the cost of wireless chargers is usually higher than that of wired chargers. Low efficiency: Due to the low efficiency of wireless charging, under the same input power, the charging speed is slower than the line charging, especially the fast charging function of some brands.
5, for the human body: wireless charging technology is safe and 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, wireless charging technology enablesThe magnetic field itself is harmless to humans.
6, the harm is relatively small can be ignored, wireless charging technology has appeared in the 19th century, but the popularity of mobile phone applications is not high. It uses the principle of "magnetic resonance" to allow the wireless charger to transmit an electric charge through the air to the phone's battery. Many wireless chargers on the market do not indicate radiation values, and electromagnetic radiation standards for wireless chargers have not yet been introduced.
