Not sure what led Techcrunch to report otherwise, but there are only two Thunderbolt ports... one of which is used to connect to the host Mac, so it merely allows you to daisy chain other Thunderbolt devices.

Where is Ralph Nader? Demand revisions to these unsafe at any wattage adapters.

And don't buy into Apple's propaganda. The fact that these no longer ship with new apple laptops? Disinformation. The design is six years old? How convenient. Such an obvious flaw couldn't have possibly taken six years to be discovered. Wild conjecture. And those new magnetic adapters are clearly just more Apple spin control.

And don't get distracted by so-called timely shortcomings... like the absence of an Empower or other aircraft adapter for the new MacBooks because Apple won't license the freakin' connector. Come on Apple, give us an aircraft adapter, or step aside so someone else can.
