Wireless charging tech could expand to laptops

The wireless technology that lets people power up their smartphones and tablets is now being envisioned for laptops.

laptop_artThe Alliance for Wireless Power says it is introducing a new version of its Rezence charging technology that would let people power devices from 20 to 50 watts, including laptops, Ultrabooks and small appliances, without a cord.

The nonprofit alliance has also taken on a new member. Dell becomes the first major PC manufacturer to join the wireless power standards initiative.

It’s a coup for the alliance, which last week reached an agreement with the Power Matters Alliance so that both would work jointly to accelerate growth of the wireless charging market.
