The obsession of the internet folks with "wireless power" is ridiculous.

@cweickhmann My electric toothbrush has one!

@trinsec @cweickhmann

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.

@trinsec @cweickhmann

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.

@trinsec
To be honest though: an electric toothbrush's electrodes would not in a million years pose a threat to anyone. They're typically at maybe 5, max. 9V. Go lick that to even feel it 😅
