@cweickhmann My electric toothbrush has one!
I think wireless charging is inefficient, isn't it? Does your tooth brush or charger get warm when it charges?
@Pat @cweickhmann Not really, because it's not a lot of power needed for charging a toothbrush.
Besides, for in a bathroom an induction charger is great because of less danger of electric shock, so that's a great reason to have one there.
That makes sense for that safety reason, but my understanding is that it works like a transformer, except the primary and secondary are in separeate units. And a transformer is inefficient.
There is also a way to transmit power via RF, usually microwaves, but I think that's inefficient, too.
@Pat @cweickhmann Yup, it's indeed inefficient. That's why you usually find it in spots that's actually safer with this.
@cweickhmann When I was a little kid, we had an electric toothbrush that you had to plug in... so um, yeah, let's embrace the induction charging here. ;)
