does no harm to mobile phones. The wireless charger uses the latest wireless charging technology, produced by using coils betweenThe generated alternating magnetic field, the transmission of electrical energy, inductive coupling technology will become the bridge connecting the charging base station and the equipment. In theory, 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.
Wireless charger does not harm the phone. The wireless charger uses electromagnetic induction technology, which transmits energy by using a magnetic field generated between coils, which decouples the current from the charging discCombined with the mobile phone battery, for the battery, its charging process is no different from that of an ordinary wired charger.
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.
However, some experts said that wireless charged with radiation , radiation is not only generated by wireless chargers wireless charged with radiation , computers, mobile phones, WiFi, TV, microwave ovens, etc., also have radiation wireless charged with radiation , There is a problem of superimposed radiation. Some experts remind that when using products with electromagnetic radiation, it is best to maintain an appropriate distance, and develop the habit of washing your face and hands after use to effectively reduce the adverse effects of electromagnetic radiation on health.
Many wireless chargers on the market do not indicate radiation values, and electromagnetic radiation standards for wireless chargers have not yet been introduced. According to the Regulations on Electromagnetic Radiation Protection, the average specific absorption rate (SAR) of the whole body of ordinary users should be less than 0.02W/kg for any consecutive 6 minutes within 1 day and 24 hours. Wireless charging, the principle is inductive charging. Samsung uses the same technology in its flagship Galaxy phones.
Although the technical content of the equipment is high, the economic cost of the equipment is higher and the maintenance cost is large. Because of the realization of long-distance high-power wireless magnetoelectric conversion, so the equipmentHigh energy consumption. As the distance and power of wireless charging devices increase, the loss of idle work will be greater. He Guili, director of the Tel Laboratory of the Telecommunication Research Institute of the Ministry of Industry and Information Technology, said that the wireless charger has radiation is inevitable, but since it has been listed, it means that it must meet international standards and will not cause harm to the human body. "As long as the wireless charger is done according to the technical specifications, it will not have a radiation hazard to the human body." He Guili said. This shows that the Internet rumors are not true.
First answer no: Yes. The working power of the wireless charger is larger than that of the mobile phone, compared with the electromagnetic field energy radiatedIt's bigger than a cell phone.
Low efficiency: energy storage and transmission efficiency is less than real contact. Slow charging speed: Due to low efficiency, the charging speed is slow at the same input power. High cost: The charger needs to have an electronic circuit to promote the wireless coil, and the electrical device needs to have an electronic device to change the power, both also need to have a wireless coil, so the cost is higher than the direct contact.
Disadvantages of mobile phone wireless charging Although the technical content of the equipment is high, the economy of the equipment is successfulThe cost is high and the maintenance cost is large. Because of the realization of long-distance high-power wireless magnetoelectric conversion, the energy consumption of the equipment is high. As the distance and power of wireless charging devices increase, the loss of idle work will be greater.

2, no harm to mobile phones. Wireless chargingElectrical appliances use the latest wireless charging technology, through the use of alternating magnetic fields generated between the coils, the transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
3, any other object (whether metal or coil) placed in it will not trigger charging. In addition, the normal charging disc has a temperature detection function, once found that the temperature exceeds the standard will stop charging. If this is still a problem, it is recommended to stay away or use fewer electronic devices. Experts point out that wireless chargers are not the only devices that emit radiation.
4, First answer no: Yes. wirelessThe working power of the charger is larger than that of the mobile phone, and the electromagnetic field energy radiated by the charger is larger than that of the mobile phone.
Total wireless charging radiation For mobile phone wireless charger Wireless charging radiation , in daily use is still very safe, you can rest assured to buy and use. Of course, if you want to charge very fast, or even reach the speed of second charging, use a similar carA wireless charger to charge a mobile phone, close use will still bring magnetic radiation damage, it is not recommended to play this way.
Views and Suggestions Wireless charged radiation : Although the radiation hazard of wireless chargers is relatively small, it should be wary of its cumulative effect with other sources of radiation in daily life. At present, the electromagnetic radiation standard of wireless charging is still under development, it is recommended that users pay attention to the radiation value of the product when purchasing and using, and minimize the use of multiple radiation sources at the same time, especially for the elderly, children, pregnant women and other sensitive groups.
If this is stillA question that recommends staying away from or using fewer electronic devices. Experts point out that wireless chargers are not the only devices that emit radiation. Users are now exposed to more and more radiation: computers, tablets, mobile phones, WiFi, TVS, microwaves... The superimposed radiation is very high. Long-term exposure to high levels of radiation can be a health hazard.
Disadvantages of mobile phone wireless charging Although the technical content of the equipment is high, the economic cost of the equipment is high and the maintenance cost is large. Because of the realization of long-distance high-power wireless magnetoelectric conversion, the energy consumption of the equipment is high. Along with wireless charging devices
