Yes, I have seen these several places. Usually they will accommodate a
couple of "wall warts" plus some regular plugs. Look at Radio Shack or Comp
USA. Or, better yet, look on the internet.
Actually, the best way to handle plugging multiple "wall warts" in is just
to get a short (6-inch) extension cord for each. I have seen these at Lowes
and also on the internet.
REPLY
The reason I asked, and specified six (6) or more cubes at once is because I
heard one Yacht captain complain that his new yacht did not provide for a
charging center.
Upon reflection, I realized he was right and the same complaint could be
levelled against most rawlers that I know of.
With cell hones, hand helf VHF, cam corders, and battery chargers for
everything under the sun, such a power center is really a necessity on board
most boats. Short jumper cords and mickey mouse juryrigs simply doesn't hack
it.
A seagoing power/recharge center has to be able to accomodate six seperate
cubes at once.
There must be space for a charging cradle to be fastened down on a shelf
holding each item secure, and it must be ssumed that all these devices are
being charrged at the same time ( possibly overnight)
As an added stipulation I woudl say that this power center should probably
be fed from an (sine wave) inverter.
Yes I recognize the prevalence of cigarette plug connectors. However!!!
They used to be called cigar lighters. A name which clearly show what
criteria determined their original size.
From a mechanical, electrical, not to mention space/volume criteria; these
are about the worst possible design you could imagine for a boat. Remember
that the original SAE criteria limits the current to 8 amps or about 90
watts.
They are not water or even moisture proof, most are not made of corrosion
resistant parts, and the design does not lend itself to any great
improvement. Any one of several connector styles used under the hood of a
modern car is vastly superior in performance for a marine like environment.
If I was building a boat for myself right now I would cut off the lighter
plug and fit something better on all the devices using this kind of plug.

Arild
