Wireless power chargers that have been developed this far are even able to charge a laptop without plugging it in somewhere. Of course, they can also be used for mobile phones, mp3 players and other type of devices with a low electricity demand. In the future it might even be able to use wireless power chargers for bigger equipment but that kind of a technology still needs some time to be developed. But all of this is the way of the future and how electricity will be transferred maybe as soon as a decade later. Who knows what might happen in the future, but probably it will happen with the help of wireless power.
