The addition of wireless charging function makes the charging method of iPhone12 more flexible and convenient. Compared with traditional wired charging, wireless charging does not need to connect cables, reducing interface wear and cable management trouble. In addition, with the development of wireless charging technology, wireless chargers can now be achieved fasterCharging speed, although there is still a certain gap compared with wired fast charging, but has been able to meet the needs of most users.
The iPhone12 can be charged wirelessly or via wired. The two have their own advantages and disadvantages, magnetic wireless charging is more convenient, direct, gently close to magnetic charging; Wired charging is faster and can achieve PD fast charging, but it is relatively not so convenient. The Apple iPhone8 began to support wireless charging, and the iPhone12 was upgraded to MagSafe magnetic charging.
AppleIt's a problem every phone has. It's inevitable.
2, wireless charging good. In wireless 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, hello, of course, flash charger is fast, VOOC flash charging: VOOC flash charging is the world's first mass-produced commercial fast charging scheme, compared with other fast charging sideIn this case, the technical threshold is higher, and the VOOC flash charge requires a customized adapter and battery to be used together. OPPO customized a special adapter, battery, data cable, circuit, interface, and for this in-depth development of intelligent all-end five-level protection technology, security is impeccable.
4, obviously, there is still a gap in the charging efficiency of wireless chargers, and there is room for further improvement in technology. From the above differences, it can be seen that wireless charging and wired charging have their own advantages and disadvantages, wireless charging can be used when charging connected headphones, but the price is higherExpensive and can't be used while charging; The advantage of wired charging is that it is cheap and portable. 5, obviously, there is still a gap in the charging efficiency of wireless chargers, and there is still room for further improvement in technology. Wired faster, although wireless charging is a very practical function, but only some users, wired charging faster, wireless charging more flexible, get rid of the bondage of the wire, pick up and put down, without alignment, you can quickly charge. Both sides have their advantages and disadvantages and can make up for each other.
6, therefore, many smart phones have begun to apply wireless charging to mobile phones. marketplaceIs there a wireless charger that works? [Magic Scorpion flat wireless charger] : Built-in active heat dissipation design can make wireless charging faster and more stable power, support 5W and 10W wireless fast full user charging needs. Support for active heat dissipation function, coupled with the price of about 100 yuan, also makes this wireless charger very popular.
2, wireless charging good. In wireless 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 wired chargingAppliances, and a wireless charging pad.
3, today we will talk about the advantages and disadvantages of wireless charging treasure and wired charging treasure, as well as their applicable scenarios. Advantages and disadvantages of wireless charging treasure: Advantages: Easy to operate: wireless charging treasure is really very convenient, because it through the electromagnetic induction wireless technology, you only need to put the device that supports wireless charging on it, it can automatically charge you, eliminating the tedious plug-in steps.
4, wired faster, although wireless charging is a very practical function, but only some users, wired charging faster, wireless charging moreFlexible, get rid of the bondage of the wire, pick up and put down, without alignment, you can charge quickly. Both sides have their advantages and disadvantages and can make up for each other.
1, wireless charging is through the electromagnetic field. Not the radiation risk of high-power fast charging. Only slow charge. It'll take a few hours. Hours. Why save a few seconds plugging in a socket? And wireless charging to improve efficiency requires precise berths. And wired charging actually requires very low parking accuracy, long wires ah. In additionWired charging has plenty of room for improvement. Like a plug that comes off easily without being crushed. 2, wireless charging technology has not been widely popular reasons are: the number of terminals less two years ago Nokia Lumia 920 built-in Qi wireless charging technology, and randomly equipped with wireless charging board, but no other manufacturers follow up. Although some third-party manufacturers have also launched wireless charging accessories, but need to install a special shell, it is not compatible with other digital devices, the use of inconvenient form.
3, the principle of wireless charging is magnetic induction, and the magnetic flux of the magnetic field must be very largeLow charging efficiency, adverse to human health and interference with electronic equipment. And most of the cars don't have sensors.
4, electric vehicle charging needs to be fast, wireless charging power is difficult to meet the standard of wired charging, in addition, the car wireless charging because it belongs to high-power electromagnetic field, safety is also questioned. 5, the status of wireless charging products: The number of terminals is small and the standards are different in recent years, we can almost forget the existence of network cables, because mobile phones, tablets are basically built-in WIFI, some ultra-thin laptops have abandoned the traditional LAN interface, wireless network in a certain wayDegree has replaced wired. But why isn't wireless charging as popular as WIFI? First, the small number of terminals is the first problem.
6, because the charger and the electrical appliance transfer energy through the magnetic field, there is no wire connection between the two, so the charger and the electrical appliance can be exposed without conductive contact. According to Baidu Encyclopedia, the wireless charging of mobile phone charging is actually low-power wireless charging, that is, electromagnetic induction charging, and wireless charging in the car is actually the output of electromagnetic induction wireless charging in the car.
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 way to make it is to connect the metal pole of the wireless charger receiving device to the metal sheet of the charging electrode of your own phone, and then drag the wire outside to receive from the outside.) The heat is caused by the large current in the charger, which leads to obvious heat.
Same output power, same output power case, wireless chargerThere will be a loss during charging, and the loss is 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.
Hello! Using the original charger is faster, and wireless charging is slower.
The efficiency of wireless charging is lower than that of wired charging, but in the future, with the rapid progress of wireless charging technology, it is likely to be better than wired charging in charging efficiency. However, the technology limited by wireless charging is not advanced enough, so the charging efficiency of wireless charging technology is higher than that of wiredCharging is less efficient. At this stage, wireless charging is more as a supplement and auxiliary to wired charging.
