There's no danger, no electrocution.
1. Wireless charging technology is a relatively new technology at present. The principle is somewhat similar to the propagation of electromagnetic waves in the air, but the transmission distance is not far, generally only ten centimeters to be more effective.
2, because the transmission distance is very close, in order to achieve charging, it is necessary to put the device to be charged near the charger in order to charge. After that, it doesn't work.
3, the current wireless charging is low voltage, commonly used in mobile phones, low voltage, safe voltage, there is no danger of electric shock.
4, Therefore, based on the distance is very close, and it is safe and low voltage, so wireless charging is safe, there is no danger of electric shock.
