Disadvantages -- the obvious one already mentioned in your post, that many accessories have cigarette lighter style plugs and, second, the two prongs can sometimes a bit difficult to plug in. To deal with the first disadvantage, it's a fairly simple job to cut off the cigarette plug from your accessory and install a two-prong connector using a couple of water-proof butt connectors. Or, you can go the other way and splice a the female end of a cigarette-style plug to a two-pronged connector and make yourself an adapter.

All of this is very helpful. I was thinking about building several 2 pin to cigarette adapters... so it's nice to hear that others have thought about doing the same thing.
I'm not sure where to find the plugs... is there a part number or type for this plug?
