Fuss over wireless charging iphone?

Why is it considered such a great new invention?
How do people think Transformers and cordless tooth brushes work?
The technology has been around for more than a century.

Do you own one? They sit on a holder to charge via electromagnetic field.

chito, May 29, 9:42pm
Yeah. all you need is a winding in the base unit and a winding and rectifier in the receiver unit. Not rocket science. Mr Faraday probably had one.

doggitt, May 29, 9:45pm
Ok, so have you looked into why the big fus over the iPhone one?

doggitt, May 29, 9:47pm
Wireless charging for phones first came out about five years ago from memory. But they said it was problematic.
I know the technology existed earlier.

Fuss over wireless charging iPhone?

You sure the iPhone has wireless charging?

It's been available for quite a few phones for some time but it not that efficient.

I'm pretty sure it doesn't. The samsung S6 does.

things like electric toothbrushes sit in a dock on top of some metal contacts. Phones sit on a plastic matt and charge without the use of contacts.

You are right. There are adaptors for iphone and other phones but they use the charging port.

Not mine.
My toothbrush has no contacts. Just 2 halves of a transformer that come together when the toothbrush is seated in its cradle.

That's interesting. Ah well. You know Apple, they always did it first no matter who else did it 10 years ago.

Ford didn't invent the car they just popularised it and made it desireable - still a big achievement when a company does that, then the competitors will follow.
