It was sitting on the coffee table plugged in, I picked it up and the cord snagged on the chair and it detached. I reattached it and it wasn't working. So then I tried the oem cable and that wasn't working in the port, then I tried and SD card reader and that didn't work. There was no physical damage to the port at all. Took it into Apple and they ran the diagnostics on it and confirmed the port was not functioning and was completely dead. There was no signal detected at all when they ran the diagnostics. They told me they thought just the port can be replaced but when it came back the whole logic board was replaced. I'm assuming it shorted something out. My other ports were working just fine, just not the one that I had the tip plugged into. It was covered under warranty (I didn't tell them I used a non-oem cable) so it didn't cost me anything to repair but I will not be using that cable again.
I had similar experience with similar type of connector bought from amazon.... I'm now giving Griffins Magnetic cable try for couple weeks , working fine so far. I notice the one from griffins has only 3 and larger pins connections versus like 5 or 6 smaller ones. who knows ... but stay away from connectors with all those little pins. they definitely have the potential to fry your port.
