There are also plugs allowing products such as laptops and handheld games consoles to be charged via the Powermat.
The principle of electromagnetic induction was independently discovered by Michael Faraday and Joseph Henry in the 1830s, when they found that current flowing through one wire induces a current in a neighbouring wire.

Definition: Wireless power technology transmits electricity to devices without the use of cables.
Impact: Any low-power device, such as a cell phone, iPod, or laptop, could recharge automatically simply by coming within range of a wireless power source, eliminating the need for multiple cables—and perhaps, eventually, for batteries.
Context: Eliminating the power cord would make today’s ubiquitous portable electronics truly wireless. A number of researchers and startups are making headway in this growing field.
