does it plug in to an existing 12 volt opening

It fits either the old style sockets where the set screw fits in a notch, and then you flip the cover the rest of the way back, or the kind with a plastic locking mechanism. Basically if your boat has the lighting socket aleady it should work. Also, since this is led polarity matters. If it doesn't work when you turn on the power, take the top apart, take the bulb out, twist it 180 and put it back in and you're set.

It has a connection for a 4.5 volt plug in but doesn't come with one. You would have to add it separately.

yes it does, there is a knock-out plug. just knock it in and it is ground up. (plastic)

No. It must be wired into an existing outlet box (it has only connections, no wire and definitely no plug nor switch).

It attaches to our old existing door opener. It just takes a standard home current. 110v.

No. You need to get your own. They have a "usually ordered with" section that prescribes a standard, cheap 12-volt adapter.

Yes it comes with the 12volt plug by default. You may have to buy the a/c adapter so you can plug it in a A/C outlet at home.

It needs to also be tapped into a 12v source. Mine is installed behind my stereo.

It has a power cord but not sure about 12 volt connector. Love my little TV.

NO! Although it pops up in search for battery operated lights, it plugs in. Yet another in the myriad Amazon search fails.

No. Has the old connector plug. There should be a new one available with the new connector

No it does not. I tried to find a connection for an adapter for house current, but could not find one.

Yes it has an attached cord so it just plugs into a socket. Installation was no problem.

Don't forget you need to have access to plug into 110v for this power supply to operate, if you will, then it would operate your 12 volt device.

No, it plugs into an electrical outlet. And this is a replacement keypad only. There is also a control unit and this actually plugs into the outlet and contains the circuit boards that actually control the garage door opening unit.

Yes, the existing fuse for the 12v outlet will go in the add a circuit along with the fuse for the new circuit.

It only plugs in, I suppose an electrician could re-wire it to plug in if necessary.
