2, so if the way of wireless charging does not change, it is difficult to increase this type of user, not to mention the fire. 3, the two main camps, the Wireless Charging Alliance (A4WP) and PMA, have declared mutual compatibility, which means that future wireless charging devices based on these two standards will be able to be compatible with each other's mobile phones, greatly expanding the scope of equipment adaptation. However, there are no details on how to achieve bidirectional compatibility between the two standards. Broadongid=' What is the difference between wireless charging and wired charging bank? Which is better? '> What is the difference between wireless charging and wired charging bank? Which is better?
Slightly slower charging speed: Compared with wired charging treasure, even if it has fast charging, the charging speed of wireless charging treasure will be slightly slower, especially for devices with large-capacity batteries, and the charging time is longer. Compatibility limitations: Wireless charging bank requires devices to support Qi or other wireless charging standards, and devices that do not support wireless charging technology cannot enjoy its convenience.
The second kind of wireless charging, which worksThe principle is the most used is electromagnetic induction, wireless charging less line bondage, each charge with the release, compared with wired charging, it does not plug and unplug the data cable cumbersome, so charging is safer, more fast, its disadvantage is that the charge is relatively slow.
Apple cable charge well. The advantage of the magnetic magnet is that it can be adsorbated near, and the adsorption can be charged. The charger is automatically aligned with the position of the charging coil, which solves the problem of manual alignment for traditional wireless charging. But it is still a wired form, and the power is not as good as wired charging, so the key moment or wired charging is more realistic. If MagSafe magnetic chargeIf you want to turn an appliance into a normal one, it will depend on when the iPhone is removed from the charging port.
Wireless charging mobile phones on the market mainly use the principle of electromagnetic induction to achieve wireless charging. There is no interface between the charger and the phone. The phone has a built-in receiving coil, and the charger has a built-in sending coil. They use electromagnetic induction between them to charge the phone. No matter what brand of mobile phone you buy, as long as it is compatible with the wireless charging standard of the charging head, it can be charged basically.
NoneOf course, the actual role of line charging is there, it can facilitate the charging process, directly put the phone on it can be directly charged, eliminating the plug process, of course, this also eliminates the trouble of carrying the charging line such as knotting, and the general wireless charging mobile phones can be charged between mobile phones.
Friends who care about battery life, all wireless chargers without heat dissipation should be carefully considered! For those who care about charging speed, the iPhone is not suitable for wireless charging. Don't care about charging speed, don't care about battery life, you can buy a support iPhone5WThe output of wireless charging, the actual performance and MagSafe magnetic wireless charger gap is almost negligible.
Not long-term overshoot, but put. If the phone is not idle, it will not overshoot, mainly overshoot. The use of wireless charging is basically between 80% and 100%. Great for battery maintenance. 3, reduce interface loss: I have used 6p to 8p, and I can obviously feel the resistance at the interface of 8P, which should be waterproof. Water resistance diminishes with use. Generally use wireless charging, reduce the drag line to play mobile phones, interface loss will be much smaller.
Wireless chargingNot chicken ribs, actually, 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.
After 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. Some people often give their phone to a wired charger when using itI fell, but that never happens with wireless. This wireless charger is designed to meet the needs of more young people.
Electromagnetic induction wireless charging, is the use of the power supply side (wireless charging board) and the induction magnet on the receiving side (mobile phone) generated between the induction flux, the magnetic force into electricity and then transmission. The advantage of this charging method is that the circuit structure required by the device is relatively simple, the charging device can be miniaturized, and the cost is cheap, and the charging efficiency will be relatively higher.
The first is field-coupled charging. First, the phone and charging kitThere are two sets of asymmetrical electric dipoles. When they are close together, they produce a coupling phenomenon and achieve the transmission of current. The transfer efficiency is good, but there are distance restrictions, and large capacity charging stations are required. The second type is magnetic resonance charging, which is different from the above electric field. This method generates electrical energy through the resonance of the same frequency magnetic field generated by the resonators at both ends.
