Theoretically, wireless charging technology is harmless to human body. The resonance principle used in wireless charging is magnetic resonance, which can only be transmitted between coils that resonate at the same frequency, while other devices cannot accept the wave band. In addition, the magnetic field used in wireless charging technology is harmless to human body.

But wireless charging is a new type of charging technology, and in the case of wireless charger, many people worry that it will be as harmless as wi-fi and mobile phone masts.

Wireless charging USES magnetic resonance to transmit power in the electric and magnetic fields between the charger and the device, while coils and capacitors resonate between the charger and the device.

The system could be widely used in the future, such as charging areas for electric cars and charging systems for the transmission of power from computer chips, which would require a charging time of one hundred and fifty times that of the current system.

Conversion rate has been a lot of people worry about, through the study, at the Massachusetts institute of technology of wireless charging technology loss lower than cable charging technology wireless charging cable is a few percentage points higher than the high conversion rate, also is the key to the in the global application of the wireless charger factors but wireless charging technology is limited to the distance, the future development, must need to solve the long-distance transmission for accurate positioning problem of wave and magnetic field range.

Core chip is one of the difficulties in the application of wireless charging technology in products: precise radiation range control, magnetic field frequency and other controls are all realized by the chip

Wireless charger cell phone under normal circumstances is not damage, the working frequency of wireless charging now do below 1 m, so the impact on the mobile phone signals do not have wireless charging of mobile phone battery life is also have no effect, and the cable charging basic same, but lower rate, but the wireless charger power conversion rate is very high, more energy saving

Wireless charger, mainly USES the inductive coupling, because the coupling technology, mainly through the coil magnetic field creates an electric current, battery internal component itself does not constitute a magnetic field, so in the process of electricity won't harm the battery's internal structure on the market at present most of the mobile phone QI wireless charging standard, built in the wireless receiver, it has a rated voltage and current, so there is no influence of wireless charger for mobile phone
