Has there been any research done on the safety of wireless charging?
- Eric_WVGG 8y agoIt’s a very simple technology, just magnets. There’s no weird radio waves to worry about.
- alonmower 8y agoPedantic but it is using induction coils to generate and receive a magnetic field, not using actual magnets. Still, not producing anything I’d worry about at all
- LeonM 8y agoDepends on what safety aspect you mean. If you are concerned about wireless charging causing harm to living creatures due to radiation: yes there has been countless studies on the effects of (EM) radiation. There are also strict regulations about the use of EM radiation. [0] But since Qi wireless charging has such a weak low frequency radiation, and (mostly) magnetic coupling, I wouldn't worry about it. If you are talking about fire/explosion safety: wireless charging will heat up the charging device slightly more than charging by cable due to a lower efficiency. The charging device usually monitors the battery temperature and may decide to stop charging if it exceeds a certain threshold. Some cheap devices (!= apple) may not implement this and overheat when charging, but this has little to do with the wireless aspect of charging. If you are worried about electrical safety of the wireless chargers: they need to comply with safety regulations before they are allowed to be sold.
