I am guessing they have licensed magsafe from Apple. Pretty sure they would get a call from Apple lawyers otherwise. There are universal chargers and batteries with all sorts of connectors which are not patent encumbered.
Kind of makes me wonder if Apple would cooperate at this stage and then consider buying the company later.
Fair enough. Obviously pg isn't naive enough to invest in a company that will get sued out of existence by Apple tomorrow. So most likely this product is a proof of concept of the technology and is circumventing the issue by perhaps incorporating Apple's MagSafe2 into their offering.
