A few months ago someone posted a mod using a cigarette lighter. I ordered some from the thread's link and when I got the lighters I tossed them in the box and forgot about them. A couple of days ago I stumbled across them and modded this one. It's the easiest and cheapest I've seen....one wire and a few minutes prepping the atty connector. If anyone knows who found these I'd like to give them credit.....and maybe it will help me remember where I ordered them from. 
There's room to make it into a 5v or even VV.
