1, expensive wireless chargeBetter quality, cheap wireless charging quality is not good, this is the difference between them, generally the more expensive wireless charging years will be longer in the future.
2, the difference between airpods wireless and wired The difference between AirPods wireless charging version and wired charging version, there is and only the difference between the charging box. The wired charging version of the charging box is the same as the first generation, only supporting the connection of lightning data cable charging. The wireless charging version is equipped with a charging box that supports wireless charging, which can be easily charged by simply placing it on the wireless charging board.
3, bound:Bridge. The charger is the use of high-frequency power technology, the use of advanced intelligent dynamic adjustment charging technology. The charger (charger) can be divided into power frequency machine and high frequency machine according to the working frequency of the design circuit.
2, no harm to mobile phones. Wireless charger uses the latest wireless charging technology, by using the alternating magnetic field generated between the coils, the transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
3, wireless charger will not cause harm to the mobile phone battery. The wireless charger works by electromagnetic induction to charge, which is a non-contactType of charging mode. This charging method is not much different from wired charging in nature, so it will not cause special harm to the phone battery. To understand this, you first need to know the basic composition of a cell phone battery.
4, wireless charger itself will not cause harm to the mobile phone battery. The principle of the wireless charger is to use magnetic field induction technology to generate a magnetic field between the charger and the mobile phone, thereby transmitting electrical energy to the mobile phone battery. In this process, there is no physical contact or chemical reaction, so there is no harm to the battery. However, if you use wireless charging improperly or frequently, it may be wrongBattery life has a certain impact.
5, generally speaking, wireless chargers do not harm mobile phones. The wireless charger uses electromagnetic induction technology, which transmits energy by using a magnetic field generated between coils, coupling the current from the charging disc to the mobile phone battery, for the battery, its charging process is no different from that of an ordinary wired charger.
Actually have toIt is 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.
Wireless charger is good, convenient, safe and durable; The disadvantages are bondage, high price and low efficiency. Advantages of wireless charger: 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.
Slightly less efficient: the general charger also has a transformer but wireless charging to transmit the lineThe transformer composed of the circle and the receiving coil is limited in structure, and the efficiency of energy transmission is theoretically lower than that of a 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.
Convenient: no need to connect with a wire when charging, as long as it is placed 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 charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
Connect the standard charger and data cable of the mobile phone to the wireless charger, and then put the mobile phone in the center position of the left and right of the wireless charger base, you can realize wireless charging, the indicator light will have a breathing effect, 5 seconds later, plug and play, convenient and quick.
The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
