Since the iPhone added wireless charging to its phones, the technology, which has been long ripe, has become popular. The Experts predict that by 2020, more than half of mobile phones in the market all will have wireless charging capabilities.
The first wireless charging device of China, also available at CES, make a sence that the charging line is about to become a thing of the past.
The wireless chargers, in addition to the regular ones we see in the mobile phone store, have a lot of unexpected new versions.

Of course, if your phone doesn't have a wireless charging feature for now, it can be achieved by buying a wireless charging receiver. The function is convenient, and there may be a large number of people who care about radiation.
First of all, we know the principle of wireless charging, famous electromagnetic induction theory as its theoretical basis, simply to say that the current when the flow through the coil, can produce a magnetic field, and near the coil of the magnetic field, can produce induced current, there, the wireless transmission of current is realized.
CCTV has did a little experiment for such problems, using high sensitivity radiation tester, measure the wireless charger, after connected to the power supply, when compared to shut off the power increase of radiation dose, radiation intensity by wireless charger.
When the power is turned on, the value increases to 150 to 180, and the increment is not obvious, but it does show that there is a magnetic field radiation.
Compared to the wireless charger, the radiation of the cell phone is much larger, and some phones have a radiation value of up to 2000 when the phone is connected.
Actually, the wireless charger is still environmental and health.
