Wireless chargers have become a necessity for many people. Their convenient use means that people no longer need to plug in cables for charging. Just put your phone on the charger to complete the charging, which is very convenient. So, how does a wireless charger work? How to choose a wireless charger that suits you? Let’s discuss it together.For these reasons, I think sports video camera The situation is still optimistic, and the market is still in a blue ocean stage. https://www.xtwkitway.com/
01 Working principle of wireless charger
The principle of fast wireless charging is to use electromagnetic induction to convert electrical energy into wireless energy. When current passes through the coil, a magnetic field is generated. When the magnetic flux of the closed circuit changes, an induced electromotive force is generated. The wireless charging station base is responsible for converting the current into a constantly changing magnetic field. Because there is a coil on the back cover of the charging device, when the magnetic field of the base changes, the magnetic flux in the coil also changes, thereby generating an induced electromotive force to charge the device.

02 Advantages and disadvantages of wireless chargers
Advantages:
Eliminate the trouble of cables
The traditional charging method requires the use of a charging cable to connect the power supply and the charging device, which is not convenient. The fast wireless charger uses wireless transmission technology to eliminate the trouble of cables and make the charging experience more convenient. There is no need to worry about the entanglement and damage of the wires, and it also saves the trouble of finding charging cables.
Protect charging devices
Traditional chargers need to be plugged in and out. Long-term plugging and unplugging can easily damage the charging port and affect the service life of the device. Wireless chargers can avoid wear and tear during plugging and unplugging, and will not cause physical damage to charging devices, making them safer and more reliable. Because wireless chargers are usually a panel that can be embedded in more flat scenes, they will also be more concealed and beautiful.

Disadvantages:
Slower charging speed
Since wireless charging station need to transmit electrical energy to devices through wireless transmission technology, their charging speed is slower than traditional charging methods. For current wireless charging, the supported output power is generally 5~10w, while the wired charging strategy reaches up to 120w. At the same time, the more popular gallium nitride chargers can support 65w fast charging. In terms of charging speed, wireless charging is still in its early stages.
Insufficient charging distance
Wireless chargers need to maintain a certain distance from the device, generally between 3-8mm, and cannot be charged beyond this distance. Therefore, it is not as practical as traditional chargers, and there will be certain limitations in the use scenarios.
