Wireless charging still has strings attached


As obviously useful as wireless charging is, it suffers from a Tower of Babel problem with incompatible standards and competing interests keeping it from truly going mainstream.

But the industry may yet be inching toward some level of sanity. AT&T is seeking from its handset vendors a commitment to one standard of wireless charging, CNET has learned.

The standard, known as PMA, or the Power Matters Alliance, is spearheaded by Powermat Technologies and Procter & Gamble, two unlikely leaders considering their highest-profile products are the bulky iPhone charging covers that only true power-hungry users submit themselves to using. But over the last few months, the PMA has seen a tenfold increase in membership, and its technology is used in Boston-area Starbucks, and will be used in select European McDonald's.
