Is wireless charger harmful to human body and mobile phone
2019-10-24 14:18:05

Now the wireless charger is very common, but there are still many misunderstandings about it. For example, it has radiation, which is harmful to human body, and it will heat up when charging intermittently, which will do great harm to mobile phones. Is that right? Is wireless charger harmful to human body and mobile phone? Let's argue.

First of all, let's see if the wireless charger has any adverse effect on human body.

In theory, wireless charging technology is harmless to human safety. The resonance principle of wireless charging is magnetic resonance, which is only transmitted between coils with resonance at the same frequency, while other devices cannot accept the wave band. In addition, the magnetic field used by wireless charging technology is harmless to human body.

Wireless charging technology uses magnetic resonance to transmit electric energy in the electric and magnetic fields between charger and equipment, while coil and capacitor form resonance between charger and equipment.

And these resonance human body is unable to sense, will not have any bad influence on human body. Radiation is even more ridiculous. Our earth itself is a huge magnetic field. If there is a magnetic field, there must be radiation to people, then we can't live on the earth.

Is wireless charger harmful to mobile phone?

The wireless charger will not hurt the mobile phone under normal conditions. The current working frequency of wireless charging is below 1m, so it will not affect the signal of the mobile phone. Wireless charging has no impact on the battery life of mobile phones. It is basically the same as wired charging, but the rate is lower. However, the power conversion rate of wireless charger is higher than that of wired charger, so it saves more energy.

The wireless charger mainly adopts the inductive coupling technology, because the coupling technology mainly generates current through the magnetic field of the coil, and the internal components of the battery cannot constitute a magnetic field, so the internal structure of the battery will not be damaged during the power on process.

At present, most mobile phones on the market meet Qi wireless charging standards, with a built-in wireless receiver, which has a rated voltage and current, and will automatically cut off the power if it exceeds, so the wireless charger has no impact on the mobile phone, so we can use it at ease.
