Powermat Debuts Gen 2 Conductive Chargers for Smartphones

Powermat's charging technology is based on an inductive coupling between the charging matt and the adapter on the back of the phone, not a conductive link:

The first company to not only perfect inductive-based wireless charging but to then bring it to consumers in a widely available, meaningful way via mainstream retail channels, Powermat pioneered the wireless charging category and currently leads the market in device compatibility, retail availability, technological advancement, consumer experience and brand.

I don't see anything related to the release of the Generation 2 product that indicates a change in charging technology.
