Wireless charging technology is a very popular technology in the moment, and major manufacturers are demanding to join the wireless charging function, which is also very popular among users in the consumer market. However, while we are pursuing a new technology, do we also consider its harmfulness? Everything has two sides, and so is technology. Some people have raised the question of whether there is radiation in wireless charging. Netizens think that the radiation of wireless chargers is larger than that of mobile phone networks. So in the end, whether there is radiation problem with wireless charging, will it hurt our health, we will tell you through experiments.
The principle of wireless charging is very simple. The famous electromagnetic induction principle is the theoretical basis. In simple terms, when a current flows through a coil, a magnetic field is generated, and a coil close to the magnetic field generates an induced current, thereby realizing the current. Wireless delivery. The whole process is actually very simple, just like a transformer, the iron block is connected between the two coils, and the wireless charging turns the iron block into air, thereby achieving wireless charging. In contrast, the transmission medium is different, and the efficiency is also very different. The magnetic field is in the air, and the energy loss is very large. The solution is to increase the voltage and power, and realize the concentrated transmission of energy, thereby offsetting the energy in the air. Lost in the middle. Just like high-voltage wires, long-term living in the magnetic field of high-voltage wires will have a certain impact on our health. How much harm does the magnetic field generated by the wireless charger bring to our life and health? Previously, CCTV had made a small experiment on such a problem. They invited the staff of the Beijing Telecom Business Office Dajiaoting Store to test it. The staff uses a high-sensitivity radiation tester that measures the radiation value of items such as mobile phones and the degree of electromagnetic pollution in the surrounding environment. The higher the value, the more severe the radiation.
The radiation of the wireless charger does not seem to be as large as expected, but it does not rule out that there are some inferior products on the market, which have not met the relevant regulations and standards, and cannot be judged well, but for the more common "electromagnetic radiation protection regulations" 》, the average user's average specific absorption rate (SAR) should be less than 0.02W/kg for any continuous 6-minute period within 24 hours a day.
The mobile phone wireless charger does bring some radiation to our body, but the electromagnetic radiation level is low. At the same time, due to daily use, the wireless charger and the mobile phone can only work at close distances, and the distance between them is large, and the actual damage is very small.
In general, the wireless charger for mobile phones is still very safe in daily use, so you can buy it with confidence. YMP wireless charging guarantees fast charging at the same time, it also effectively reduces the radiation damage to us. The aluminum alloy material is easy to dissipate heat, and the nanometer fineness is different from magnetic attraction, which will not interfere with the mobile phone current.
