The Alliance for Wireless Power (A4WP) is announcing an expansion of its current Rezence wireless charging specification that will offer up to 50 watts of power in the future — allowing charging of multiple devices, including laptops and tablets, with a single charger. With upgrades to the base spec expected to be finalized by the end of 2014, A4WP will have Rezence capable of powering laptops, tablets and other consumer electronics with different power requirements.
