How wireless charging works and if it's safe

Q. Hi, Kim. I heard some smartphones now support wireless charging. How does this work? Does the wireless charging signal just get transported all over the place? Won't that be a health hazard? Thanks for everything you do!

A. Wireless charging could be the next frontier for electronics. It's already on a few Android and Windows gadgets and Apple just patented its own version.


Plus, wireless charging is already in the medical field and could even be coming to electric cars soon!

Of course, we're still a few years away from widespread use. Right now, there's one popular method of wireless charging, but it doesn't really work the way you think it does.

However, with potential improvements and new techniques on the horizon, this is still an electrifying topic!

The main wireless charging standard right now is called Qi. It's used mostly in wireless charging pads and similar gadgets. Coffee shops like Starbucks are even installing cute charging pillows that use it.

Though many different phones - including recent iPhones - have compatible cases, compatibility is now being built right into newer gadgets. Android has the Nexus 4 and HTC Droid DNA while Windows offers the Nokia Lumia 920 and HTC X8.
