But they used recycled connectors as a way of using the legal argument their product was a "customer modification" of a licensed and paid for product. You sent them YOUR charger and they modified it to work with their device.
They STILL got shut down by Apple because the Mag Safe also used circuitry inside the brick that they "hacked" to make their brick work like.. Basically DRM and DMCA for power bricks shut them down.
The magsafe connector talks 1-wire, not the charger itself. It provides serial number and version info but no DRM/crypto. The Mac also uses the 1-wire to control the LEDs on the connector. See my teardown for the details: http://www.righto.com/2013/06/teardown-and-exploration-of-ma...
Nice, thanks.
What about magsafe2? same deal?
DELL also uses serial connection with the charger, with chip inside the charger. Kinda surprising Apple didnt lock it down like they are used to do.
