When i comes to modern electrical devises i am as Thick as Caveman Ugg,Give me mechanical tools/devises and i am sweet as but the black art of electrickery has me totaly baffled.

Can someone please explain to me how this fairly new Tech of no longer needing to plug devices in to charge them works thanks.

Please DO Dumb it down as the high tech talk type of things will go straight through to the keeper.
Thanks.

I've heard that its just a battery that you carry around and plug your device into, is about the size of your phone or according to wikipedia, it uses an electro-magnetic feild to transfer electricity from one object to the other  


Inductive_charging
that should help

Thanks for that.
The thing that got my interest was  an ad showing putting your mobile into a pocket/cavity/space in your Subaru,s centre console and it magically charges .

Not quite that simple Clyde.

Firstly, you need a phone that supports Wireless Charging - the more recent ones probably do, but more likely at the high end though.

Secondly, it is still like another charger, plugs into power, but you just sit the phone on or close to the 'base station' - no actual plug into the phone.

So in a car, or anywhere, there still needs to be a power source.

JB HiFi and the like sell them for about $100

That is actually a "Power Bank" - essentially a large battery that you charge, and then it can be used to charge phones etc in the normal way - popular if you are going to be away from a power point for some time and would otherwise need to charge a phone. I have one and it holds enough to charge my mobile 3-4 times before it needs a recharge. They come in different sizes/capacity. Again, the likes of JB etc sell them.

So pretty much just another hipster toy then.

Clyde, if you search for inductive charging, you’ll find some pictures of how it works. Think of a transformer in a battery charger, or an ignition coil. There are two coils of wire very close to each other. An alternating current is sent through one supply coil, which creates a magnetic field. The other coil, in this case built into the phone, picks up the magnetic field and converts it into an electrical current. This charges the battery.

You need to make sure the supply coil matches the phone coil as if it doesn’t match, the voltage created in the phone coil will be wrong.

It’s a good idea because connectors break with rough use, and you can put your phone on a desk or a stand and have it charge.

Many thanks for those easy to understand details that makes it a lot clearer to me in a nice simple way.
As i said i am pretty thick with electrical things so that helped out nicely.

All the major car manufacturers that offer a full range including premium models are starting to include built-in Qi standard wireless chargers, typically included as standard on high-end models and as an option for mid/lower-end models.

The Wireless Power Consortium website does not list any Subaru models as having wireless chargers as yet, so perhaps the one that Clyde saw was a custom retrofit of a third-party wireless charger.

Users of older smartphones without a built-in Qi charging coil (i.e. iPhone 5/6/7 series) can buy an Aircharge phone case that includes the Qi coil and plugs into the phone.
