About WiTricity’s Wireless Charging For Laptops

Over universal USB-C charging forget the hype. This wireless charging of your laptop will be the new hot topic this year. You can see the demos of the laptops that are being charged using WiTricity’s wireless charging technology. The typical inductive charging technology is been a fizzle on smartphones, but with the magnetic resonance technology, WiTricity thinks it has the edge, farther using magnetic fields it has been more powerful.

A tightly coupled magnetic field is used by WiTricity to transmit power through metal, stone or even your head and it gives far higher output, due to this it makes better suited for laptops and it will draw more power than smartphones.

WiTricity modified two off the shelf laptops to charge wirelessly by plopping them onto charging pads the laptop is charged up to 30 watts and worked as expected. Which PC OEMs are going to adopt was not announced by WiTricity, but it is said that with actual laptops shipping several companies had climbed abroad this year.

If you guess, you could say that Dell is aboard, prominently on the prototype charging pad its corporate logo was featured.

A new tech is pointed out by the WiTricity points i.e. advantage has over the inductive charging that is used by smartphones is a much larger landing zone. You typically have to line up the device charger just right to get it to work with inductive charging. It was better with the WiTricity demo but it was not perfect. The charging pads in use are mostly a limitation at this stage though, but it is said by the company that there is no limit to for the surface largeness.

In future you can imagine your entire desk is a charging pad and the only efforts required charge your phone, eReader, laptop and smartwatch is to put them down.
