Specifically, I have an Alarm Clock iPod dock with speakers that gets its power from ac wall adapter, but is only providing 12v. Is there an adapter to go 12V to 12V that will power this?
I want to put this in my camper, but run on 12V so I dont need to be plugged into shore power or have engine/generator/inverter running. I already have inverters and a generator, but this is for when dry camping and not running the engine. I have 200 watts of solar, so I am not too worried about running down my house batteries. I would rather use a standard cigarette adapter than hard wiring it to keep it portable.
Thanks

You just need to find the right barrel connector for your clock and wire it to your camper 12V battery. If this will be a permanent installation, wire it directly to a 12V tap. If needed temporarily, wire it to a cigarette lighter adapter.
Take your barrel connector to RadioShack and you should be able to find it there. You may also pick up some wire and cigarette lighter adapter.
Make sure to watch for polarity when you build the adapter.
