4, wireless charging technology has radiation to the human body Wireless Charging Association ? Does it cause cancer Wireless Charging Association ? Tests have proved that wireless chargers can indeed produce electromagnetic radiation, but the value is relatively small. Now the user is exposed toMore and more radiation: computer, tablet, mobile phone, WiFi, TV, microwave oven... The cumulative radiation value is very high, and if the user lives in such a high radiation environment for a long time, it may cause serious harm to the body and mind.
