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. 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. Two: high adaptation rate.
3, bound: wireless charging needs to be adsorbed on the charging base, can not be moved at will, for useA man is bound more than a wire. 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.
4, harm: wireless charging causes environmental harm. Let's first discuss the disadvantages of wireless charging, because it is very important. Wireless charging pads are inefficient, and depending on the design and the location of the user's phone on the charging pad, the charging efficiency can be between 30% and 80%. That said, even in idealIn the state, 20% of the electricity is wasted.
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.) Fever, because the seat is fullThere is a high current in the interior, which results in significant heating.
Different, the wireless charger will have a loss when charging, and the loss is between 30-40 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.
If the charger output is the same, or line charge much faster.
Charging speed may be limited although many wireless chargers alreadyFast charging is achieved, but in some cases, its charging speed may still not be as fast as the traditional wired charging method. Especially in the case of low power and the need for fast charging, wireless charging may not meet the needs of users. Higher cost Compared to wired chargers, wireless chargers are usually more expensive.
The convenience of wireless fast charging does not bring a significant increase in charging speed, but may be slightly lower than wired fast charging. The power output of the wireless fast charger to the wireless base is not the final output power of wireless charging, but the input power of the wireless charger. Wireless charging installed on new energy vehiclesWhich is better depends on the specific use case and requirements. Advantages of wireless charging: Convenience: Wireless charging does not need to plug in or pull out the charging cable, just put the device on the charger to start charging, very convenient. Aesthetic: Wireless charging will not damage the shell design of the device, making the overall device look more beautiful.
2, each has its own advantages: wireless charging is convenient, do not need to connect the phone to the charger, put on the charging board; Wired charging is more stable, and the charging speed is faster than wireless charging.
3, wireless charging good. In wireless charging, the charger and the charged device are noneNeed direct contact, easy to use, strong adaptability to the environment, avoiding the physical interface so there will be no interface wear, sparks, leakage and other problems, in addition to 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.
4, when charging, ensure that metal objects away from the charging plate, metal objects may make the charging plate overheat. Ensure that credit cards or other magnetic objects are kept away from the charging pad to avoid the elimination of magnetic information. Keep the remote key away from the charging pad to prevent low key charge. In the choice of charger, due to most of the Qi chargingMobile phones support up to 10W wireless charging, so it is equipped with a charging head that supports more than 10W.
5, convenience The main advantage of the wireless charger is its ease of use. There is no need to carry additional charging cables and plugs, just place the phone on the charger to start charging. This is undoubtedly a huge convenience for people who travel a lot or work outside the home. Modern wireless chargers usually have a fast charging function, and their charging efficiency is not inferior to that of wired charging.
6, not necessarily good. Because any fast charger charging current is relatively large, has an impact on battery life. It is best to charge the battery with a standard charger to ensure the longest service life and use value of the rechargeable battery.
Apple wireless charging is not fast charging. Wireless charging itself is not efficient, when using Apple's original wireless charger normal charging, it is also easy to make the Apple phone heat, if coupled with fast charging, the phone will generate more heat, so there is a certain danger, so, Apple phone under normal circumstances do not fast charge, do not use wirelessCharging, wireless charging is just an empty function, not very practical.
Yes, there are official sales of fast charging head, but the price is more expensive. Look for a used ipad charging tip, which also charges faster than the original.
Fast wireless charging speed MagSafe charger wireless charging speed is relatively fast, up to 15W fast charging, compared with the previous 7W Qi wireless charging, the speed is much faster, the fastest can be filled with nearly 50% of the electricity in 30 minutes.
Required, the fast charge head is divided into three models: standard 5v1A, fast charge 5v2A (speed up30%), flash charge 9v2A (speed up 50%). Wired charging and wireless charging use the same fast charging head.
In fact, when wired charging and wireless charging are carried out at the same time, the iPhone will refuse the input of wireless charging and continue to charge in wired charging mode. That will not explode the problem, of course, will not exist, because the iPhone's power management IC will intelligently choose the most suitable for the currentThe charging mode can monitor the charging status of the mobile phone in real time to ensure the normal operation of the mobile phone power supply.
High charging efficiency, fast charging speed. Plug in wireless charging and then plug in wired charging, wireless charging will automatically stop and switch to wired charging. Wireless charging in wired charging will ignore wireless charging and still continue wired charging.
Wireless and wired charging at the same time is not a bad problem, but it also does not have any benefits, and it also causes unnecessary (albeit small) power consumption. So don't charge your phone like this.
