I mean, OK you have to get the polarity right, and according to Murphy's Law, with two ways to wire it, you've got an 18% chance of getting that right the first time, but a voltage tester would improve the odds considerably, right?

I have a 12-volt Bluetooth hands-free mirror attachment in my car. Rather than keep taking it out and plugging it in to charge, I rigged up a small cable with the right plug/polarity tapping power off the map light in the headliner about four inches away, and now it's powered whenever the car is running. This has worked fine for three years, so I don't know why the Entourage wouldn't.

Now if we could just get the battery to charge on an inductive pad, that would be sweet.
