Nokia 920 can be charged wirelessly, using the QI wireless charging standard. Nokia Lumia 920 built-in wireless charging, just put the phone on the wireless charger tray, you can start charging the phone.
This wireless charging technology is based on the principle of electromagnetic induction, by embedding induction coils on the back of the phone, and a special wireless charging pad or wireless charging base for contact charging. When the Nokia 920 is placed on a wireless charging pad or charging dock, a magnetic field is generated between the induction coil and the charging device, and electrical energy is transmitted through changes in the magnetic field.
NokiThe 920 supports unlimited charging. Need to buy a wireless charging base, when you need to charge, put the phone back shell attached to the charging base to charge. During the wireless charging process, the phone will heat up, pay attention to safety.
Hi! The wireless charger needs to be connected to the power socket through the charging cable, and then the phone can be charged directly in the corresponding position of the charger. If it is a DC-50 portable wireless charging board (that is, a mobile power supply that supports wireless charging), the phone can be directly placed in the corresponding position to charge after opening.
1, mobile phone wireless charging refers to the charger and the electrical device between the two can charge the phone without wire connection.
2, wireless charging is also known as inductive charging or non-contact inductive charging Wireless charging tray , 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.
3, wireless charging technology (Wireless charging technology; Wireless charge technology, derived from wireless power delivery technology. Wireless charging, also known as inductive charging, non-contact inductive charging, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation.
4, according to the wireless charging tray , wireless charging technology is based on two newThe device to achieve, the first is the charger, it is connected with electricity, and then there will be a "tray" and the charger for transfer, as long as the phone and the "tray" distance within the specified range, then the phone will automatically wireless charging.
5, wireless fast charging is a combination of wireless charging technology and fast charging technology, and the mainstream models on the market now support wireless fast charging technology. Wireless fast charging mobile phones are Xiaomi Huawei P40, Mate30, Mate30 pro and so on. Wireless charging technology Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wire, so chargingIn what mobile phones are charged wirelessly?
1, vivo support wireless charging wireless charging tray mobile phone models include iQOO11Pro, X90Pro, X90Pro, XFold iQOO10Pro, X80Pro Snapdragon version, X80Pro Guet version, XFold, XNote, iQOO9Pro, X70Pro, iQOO8Pro and other vivo mobile phones.
2, Huawei Wireless charging tray : Huawei wireless charging mobile phones include Mate50 series, Mate40 series, Mate30 series, Mate20 series, Mate10 series, MateRS series, P50 series, P40 series, P30 series, etc.
3, Millet 10 new flagship millet 10 on the wireless charging tray , with up to 30W wireless flash charging function wireless charging tray , minutes to increase the power, but also with 10W fast wireless backcharging, alsoIt is said that the Mi 10 can be charged for its wireless charging tray he needs to charge the phone.
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 phone's standard charger and data cable to the wireless charger, and thenPut the mobile phone directly/horizontally in the center position of the wireless charger base, you can realize wireless charging, the indicator light will have a breathing effect, 5 seconds after the extinguish, 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.
