Sounds like you found what you need. However, IF your problem involved being able to plug into the IP with a case attached, a "flip" case could also solve the problem. On a lark, I bought an alcohol breath tester that is powered by the IP, but I found I couldn't power it with my IP in a case. So, I was also looking for an extender until I found the Countour Flip case which did away with my need for an extender cable.
A better solution for my problem in that I don't have to carry a cable around (which I would probably misplace in about a nano second.
