1, in fact, in the final analysis, this wireless charging technology is tray wireless charging decoration Our induction cooker, transformer technology tray wireless charging decoration , or it is to put our previous kind of old-fashioned, The power supply coil part of the heavy mobile phone charger is placed on the charging base, and the power supply coil part is placed in the phone.
2Nokia 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. 3, as we all know, Nokia Lumia 920 is equipped with the latest wireless charging technology, but Nokia official only said that the phone needs to be placed on the charging panel when charging, and did not disclose the maximum distance supported by this technology. Recently, foreign players released a video of testing the wireless charging distance, and the results show that Nokia Lumia 920 canRealize a certain range of air separation charging.
4, a base, the shape is a bit like a tray, put the phone on it, do not connect the charging line, you can charge the phone, but this needs mobile phone support.
5, however, it should be noted that because the transmission is not some simple data, but power, so wireless charging in the current distance requirements are more strict, the mobile phone and "tray" can only achieve close charging within 1 cm now, but with the progress of technology, this distance may be extended.
6, Nokia Lumia 920 Nokia LumThe cost depends on the type of material to be tested, and the fee will vary depending on the type of non-metallic and metallic material. Therefore, if there are more types of materials, the cost of the entire ROHS certification may be about 60,000 yuan.
2, FCC certification: The Federal Communications Commission (FCC) is the United States government authorized to regulate radio, communications and digital equipment.
3, Product safety and compliance are of Paramount importance in the global business arena. Various certifications such as CE, CCC, FC/FCC, ROHS and FDA, like passports for products, provide a solid guarantee of their right of way and consumer trust in a particular market. Let's dive into the differences between these certifications to better understand and respond.

Put the mobile phone with wireless charging function on the wireless charging board, the position should be placed, you canCharging, note that some wireless charging panels support different mobile phone models, to choose wireless charging panels according to their mobile phone models.
Wireless charger usage: the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is/horizontally placed in the wireless charger base left and right center position, you can achieve wireless charging, the indicator light will have a breathing effect, 5 seconds after the extinguish, plug and play, convenient and quick.
If your Huawei mobile phone supports wireless charging, place the mobile phone screen facing up in the center of the charger or the position recommended by the manufacturer after the wireless charger is powered onCharge it.
When charging, do not connect the charger strip to other high-power electrical appliances to prevent the current or voltage of the wireless charger to the lithium battery from being too small. When wireless charging, try not to play games, etc., to prevent the phone and wireless charger from poor contact resulting in charging failure. At the same time, when wireless charging, playing games will improve the operating efficiency of the CPU, resulting in mobile phone heating.
Steps to use wireless charging for vehicles: 1. Fix the wireless charger in the appropriate position in the vehicle cab; Connect one end of the USB data cable of the wireless charger to the car cigarette lighter and the other end to the cigarette lighterWireless charger; Fix the position of the wireless charger to ensure that it is stable and will not slip off, and then put it on the phone to charge. Wireless charging technology originated from wireless power transmission technology, can be divided into low-power wireless charging and high-power wireless charging.
First, we open the Settings option and click Battery. Step two, we click on wireless reverse charging. The third step, put the device that supports wireless charging on the back of the machine, you can wireless charging. The basic principle of wireless charging: electromagnetic induction of a certain frequency of alternating current in the primary coil generates a certain current in the secondary coil through electromagnetic induction, thereby transferring energy from the transmission endTransfer to the receiving end.
Wireless charging base: refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electric energy, inductive coupling technology will become a bridge connecting the charging base station and equipment. [Usage] : Just connect the USB cable and plug it into the socket.
A base, kind of likeTray, put the phone on it, do not need to connect the charging cable, you can charge the phone, but this requires mobile phone support.
Abstract: Charging base is a flat base style charger, it and the charging line together to form a wireless charger, you can charge the mobile phone. The charging base is generally universal, as long as the mobile phone has a built-in wireless charging module, and supports the Qi standard, it can be charged with a wireless charger. When using the charging base to charge, it also needs to be noted that the charging base has a certain induction distance, and the thickness of the phone case may not be able to charge.
Wireless charging is also known as inductive charging orNon-contact inductive charging, based on the principle of electromagnetic induction, does not need 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.
The principle of wireless charging: electromagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the transmitting coil generates a certain current in the mobile phone receiving coil based on the alternating current of a certain frequency through electromagnetic induction, thus transferring the electrical energy from the transmitting end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.
