Wireless charger is good, convenient, safe and durable; The disadvantages are bondage, high price and low efficiency. Wireless chargerBenefits: Convenient: Wireless charging belongs to one-to-many charging, which solves the problem that the interface is not applicable, and also avoids the phenomenon of poor contact caused by repeated plugging and unplugging of the mobile phone interface, which can better protect the mobile phone interface.
Efficiency is slightly lower: The general charger also has a transformer, but the wireless charging transformer composed of the transmitting coil and the receiving coil is limited in structure, and the efficiency of energy transmission is theoretically lower than that of the general charger. Slow charging speed: Because most of the current receiving products such as mobile phones limit the input power, the charging speed is relatively slow.
Convenience: no need to connect with a wire when chargingJust put it near the charger. In the case of multiple electrical devices, it can save multiple chargers, do not occupy multiple power sockets, and there is no trouble of multiple wires winding each other. Safety: No power contact design, can avoid the risk of electric shock.
Wireless charger 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 phone on it, with headphones to listen to music, but only limitedListen to music, want to play video games that is not very realistic.
Personally don't think it's necessary. First of all, you can't use the phone while charging, and secondly, the charging speed is much slower than the wired PD fast charge. It's been a bit of a delay on both sides. Wireless charging is only suitable for people who have multiple phones and improve their lives.
At present, it is not necessary, the current wireless charging technology is not perfect, and can not be charged like wifi, but also need to put the phone on the charging mat to charge, so as to countThe function of chicken ribs cannot achieve the true meaning of "wireless" : free from bondage. Charging still need to put the phone on the charger, and there is direction, can not lie down ~~. The charging power is small, and the current mobile phone line charge is generally fully charged for 1 hour, and the battery is about 4000MAH. Wireless charging is not so wonderful. It takes four hours to fill up, which isn't great for people who use their phones a lot.
Wireless charging is not a chicken rib, but a very useful charger. For people at work, they do not have time to repeatedly plug in the charger, only occasionally check whether there is a text message or phone call.With wireless charging, you can better protect the interface of the phone, and you can also have power anytime and anywhere. They will not worry about what to do when they go out without electricity, just put it on the charging site.
Low charging efficiency: Compared with wired charging, wireless charging is less efficient. That means it takes longer for users to fully charge. In addition, since wireless charging requires energy conversion between transmit and receive, it may lead to reduced battery life. Slow charging speed: Due to the low efficiency of wireless charging, the charging speed is relatively slow. This causes users to have to wait longer to complete the charge.
Different, the wireless charger will have loss and damage when chargingIt's between 30 and 40 percent. So the ordinary charger is faster than the wireless charger. There are already fast chargers and fast wireless chargers, but the results are the same. For example, the fast charging Samsung S8 takes 90 minutes, then the fast wireless charger takes 190 minutes, which is the result of my own actual testing.
is different. Moreover, according to different wireless charger manufacturers now, the current and frequency are not the same. (The students themselves bought one online, it is said that the speed is relatively fast. The production method is to connect the metal pole of the wireless charger receiving device to the noneIs it important to charge the wire to the charging electrode metal sheet of your own phone, and then drag the wire outside and receive it from the outside. The heat is caused by the large current in the charger, which leads to obvious heat.
Wireless fast charge is neither fast nor slow. Wireless fast charge is much faster than wireless fast charge, and slower than wired fast charge. The power that the charging head wired outputs to the wireless fast charge base is not the wireless fast charge output power but the wireless fast charge input power. Charging time of more than 2 hours of wireless fast charge, not as fast as the wired fast charge of 1 hour and 30 minutes, is not fast charge. I typed 18W also needs to charge for 2 and a half hours with a wireless fast charging efficiency of 60%.
1, mobile phone wireless charging is very convenient is not without practical significance. Is not unnecessary wireless charging important , wireless charging is still very convenient, such as urgent things he can let you keep full charge, when you are in front of the computer office, after using the mobile phone on the wirelessOn the charging pad, you can keep it fully charged at all times.
2, in fact, it has a certain practical significance, so that some accidents can be avoided, and the efficiency will be relatively high, and will not forget the wireless charge is important take the charger. 3, in fact, it has to be said that the wireless charger does bid farewell to the bondage of the charger line, and it is precisely because of this that it becomes more convenient and convenient, so most people prefer this way of charging.
1, wireless charging technology still needs continuous development, at present, wireless chargers are not practical, and itself is not convenient, so it needs continuous development and technical improvement. 2, in addition to the charging speed has no advantage, the safety issue of wireless charging of electric vehicles has been one of the important reasons for hindering market acceptance. Although from the point of view of scientific argument, the wavelength of the 78MHz band used by electromagnetic resonance technology is about 30 meters, which is harmless to the human body, but the demonstration of these issues still needs a lot of experiments and time to demonstrate.
3, some Samsung mobile phones support wireless charging function, to achieve the function requires a separate charging kit, wireless charging and wired charging effect is the same, but the wireless charging time is relatively longer, no impact on the phone.
