Does it cause cancer?
1, no strong radiation, no effect on the human body! The main principle is: the way of wireless charging is electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Most of the wireless charging of mobile phones uses the principle of electromagnetic induction.
2, for the human body: wireless charging technology is harmless to the human body. The resonance principle used by wireless charging is magnetic field resonance, which is transmitted only between coils resonating at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
3, conclusion: Wireless chargers do produce electromagnetic radiation, although the value is usually small, but should be wary of its possible cumulative effect. With the popularity of wireless charging technology, users are exposed to more and more radiation sources in daily life, such as mobile phones, computers, WiFi, etc., and long-term accumulation may be harmful to healthHave an impact. Wireless Charging Technology and controversy With the development of mobile Internet, the rise of wireless charging function has led to a discussion on electromagnetic radiation.
4, the harm is relatively small can be ignored, although wireless charging technology has appeared in the 19th century, but the popularity of mobile phone applications is not high. It uses the principle of "magnetic resonance" to allow the wireless charger to transmit an electric charge through the air to the phone's battery. Many wireless chargers on the market do not indicate radiation values, and electromagnetic radiation standards for wireless chargers have not yet been introduced.

6, wireless charging technology has radiation to the human body? Does it cause cancer? Tests have proved that wireless chargers can indeed produce electromagnetic radiation, but the value is relatively small. Now users are exposed to more and more radiation: computers, tablets, mobile phones, WiFi, televisions, microwave ovens... The added radiation value is very high, if the user lives in such a high radiation environment for a long timeMay cause serious physical and mental harm.
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 generating coil generates a certain current in the mobile phone receiving coil based on a certain frequency of alternating current through electromagnetic induction, thereby transferring the point energy from the originating end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.
Wireless charging system mainly adopts the principle of electromagnetic induction. Wireless charger means noThe traditional charging power line is connected to the charger on the terminal device that needs to be charged, 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 the device.

Wireless charger under normal circumstances will not harm the mobile phone, wireless charging now the working frequency is done below 1M, so the signal of the mobile phone will not have an impact.
Basically no damage: Wireless charging technology uses the principle of electromagnetic induction to transmit electrical energy through magnetic and electromagnetic fields, which has no direct damage to the internal structure of the mobile phone battery. Modern mobile phones have built-in wireless receivers with voltage and current ratings, so under normal use, wireless chargers are pairedCell phone batteries are safe. The wireless charger has a high energy conversion rate, and can automatically adjust the current according to the battery capacity, avoid overcharging or overheating of the battery, and protect the battery safety.
Wireless charger does not harm the phone. It uses electromagnetic induction technology to transfer energy through the magnetic field generated between the coils. The current is transferred from the charging disc to the phone battery, the process is no different than when using a traditional wired charger to charge the phone, so the wireless charger does not cause damage to the phone battery. Electromagnetic induction technology plays a core role in wireless chargers.

The working principle of the traditional charger is different. Wireless charging uses electromagnetic induction technology, which transmits energy through the magnetic field generated by the coil. There is no difference between the two charging methods for the mobile phone battery. Wireless charging introduction: Wireless charging is completely harmless to the human body, there will be no radiation and the like.
From the theoryFor wireless charging technology is safe and harmless to the human body, the resonance principle used by wireless charging is magnetic field resonance, which is only transmitted between coils resonating at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
Electromagnetic induction wireless charging: This way of charging is to use the inductive magnetic flux generated between a wireless charging board and the induction magnet on the mobile phone, and convert this magnetic force into an electric power for current transmission.
Wireless charging technology is based on the principle of electromagnetic induction, by converting alternating current into a magnetic fieldAnd then convert the magnetic field into alternating current to realize the process of wireless charging. There are mainly electromagnetic induction, magnetic resonance, microwave and electric field coupling four ways, among which electromagnetic induction technology is mature, high charging efficiency, simple circuit structure, so it is widely used. The phone's battery is not damaged during wireless charging.

1, there is no danger, and will not be electric shock. Wireless charging technology is relatively new at present. The principle is somewhat similar to the propagation of electromagnetic waves in the air, but the transmission distance is not far, generally only ten centimeters to be more effective. Because the transmission distance is very close, in order to achieve charging, the device to be charged must be close to the charger in order to charge. After that, it doesn't work.

3, wireless charging uses the principle of electromagnetic induction, its working frequency is very low, the harm is not big. Electromagnetic induction: 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 end to the receiving end. It is the first generation of mobile phone wireless charging, and the technology is mature, but it can only be single-to-single short-range charging (qi standard, within 1cm, within 5 watts), rather than single-to-multiple charging like WiFi.

Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone.
5, wireless charging applies the principle of electromagnetic induction, similar to a transformer, first converts an electrical signal into an electromagnetic signal, and then converts the electromagnetic signal into an electrical signal at the receiving end to achieve current-free chargingDo not worry about the danger of leakage, electric shock, and will not cause fire.
6, - ** Safety ** : Wireless charging avoids the use of live contacts and reduces the risk of electric shock. - ** Durability ** : The charging element is not exposed and is not easy to be eroded by moisture, oxygen and other substances in the air. At the same time, there are no mechanical wear and flameout problems of the contact. Convenience: Wireless charging allows the device to be charged without a physical connection, simply by placing the device near the charger.
