Induction charging - which is what the Qi standard is based on - is the most common type of wireless charging available at the moment. It generates a weak electromagnetic field that only extends a short distance from the charging pad. There are no known safety issues with this type of charging. Electric toothbrushes and other forms of household tech have been using induction charging for several years without incident. In fact, induction charging may be safer than plugging in since there are no exposed electrical connectors involved in the process, which actually reduces the risk of shocks and short circuits. So you can sleep well knowing that your Qi wireless charger does not present a danger to you or your loved ones.\r
