Do lots of phones/devices use this now? It would certainly solve the problem of wearing out the socket. I don't know why it hasn't been around longer, I had an electric toothbrush that did this TWENTY YEARS ago.
it's becoming more common but with the receiver inside the phone.
Is that a problem ?, and it woul;dn;t be solved by this device as it has to plug in to the socket. I guess you could leave it there rather than unplugging it.
The problem was getting enough current through the system to make it worthwhile, I guess there weren't any around because there weren't any mobile phones that needed them. If you think about mobiles of TWENTY YEARS ago, these things wouldn't be able to charge them very effectively.
No it's inside the case ;-) but the one you linked to is an addition, it can;t go inside the phone so it goes outside it.
It'# probbably blow out instead.
Maybe on some phones I don't know.
NO, you also need electrical power NOT just magnetism , magnetism can;t charge phones.
We can generate strong magnetism - think of transformers, in fact that's all this is - a transformer in 2 halves. But you need to connect the transformer too, usually the mains supply. That's why you have to plug your battery chargers into the wall socket to get the power.
Yes we can make really strong magnets. I remember in Beano once someone had a big magnet and he could get pulled along on his roller skates by a trolley bus. So that proves it.
But... whoops! If it's done by magnets won't the cars get pulled downwards enough to break their springs? And what if someone in the power station mixes up the red and black wires? Won't all the cars in the whole country shoot off into space? I don't think it's practical, or safe.
so it wouldn't be connected to the mains, you'd connect it to the charger.
I've no experience of this happening on any phone I've heard of. I've heard about it on laptops even repaired a few, mostly the old power books from the mid 90s, before Apple introduce the magnetic power connectors.
to wirelessly transfer what exactly.
yes and the 'power' put into your battery comes from the mains supply not the magnets.
My car has a built in wireless phone charger ... however my phone would need a 'wireless charging back' almost £50 Plus then then the standard phone cases will not fit.
Be OK when phones build in this capability as standard - but not yet.
