Wireless charging has been something of a boon for smartphones and portable electronics, and if Lenovo and Dell have anything to say about it, it should be available for laptops and tablets soon. The Alliance for Wireless Power has updated its standard to include devices that require up to 50 watts – which would catch quite a few laptops and basically every tablet on the market.
Intel expressed its own desire to eliminate all wires within the next few years, including a system that can transfer power through a thick wooden desk.
There are quite a few challenges, however, including the lack of a singular standard for all devices. Still, the idea of universal wireless chargers in airports and coffee shops is an alluring one.
