The same ebay company had this:

Looks like it would be an economical alternative to the high dollar relay decks used with stick grip switches, etc. The relay coils are 5V, but a handful of dropping resistors or a 5V supply feeding the control switches would solve that.

I think the author of the thread was also interested
in having some 'cigar lighter' jacks for the odd
appliance.
Here's a device I ran across on eBay . . .

Of course there are bumps and potholes in the translation
of specifications into English but for the most part, this
device seems a likely candidate. It features both
output voltage and current limit adjustments. This makes
it suitable for the task and even somewhat idiot proof
in that it's self protecting in case of a short circuit
or overload.
Of course, compatibility with respect to radio noise is
unknown but I've never met a noise problem I couldn't
whip.
Food for thought.
