Marine Grade Cigarette Lighter Socket 12 VDC
Can this adapter be plugged into your home outlet?
Yes, that would be possible, but very inadvisable. Physically, it should be able to handle the 120V provided by a home outlet (and may even be capable of handling 240V, but that starts getting really dicey). In order to handle a certain voltage, all that's required of a device is that the insulation on the conductors can handle the voltage, and that wherever the conductors are bare on the device, they are physically separated enough that no arcing occurs. In the case of this socket, it would appear that both of these conditions would probably be met for 120V (and maybe even 240V).HOWEVER, by directly hooking it up to a home outlet, the voltage that the home outlet produces is the voltage that this device will output. This device does not have any form of voltage conversion, so it will NOT output 12V if it is plugged into a wall outlet. This would be a major problem because virtually all devices that would plug into this socket require 12V; 120VAC would surely destroy them.If you want to use this cigarette lighter socket in a home, and you want it to output 12V DC, then you will need to connect it to a power supply that outputs 12V DC. I've added links to a few power supplies from Parts Express that would work for this. Basically, you need a supply that outputs 12V DC, and which is capable of delivering the amount of current that your devices will draw.Alternately, you could just buy a AC adapter that includes a built-in cigarette lighter socket. I've included a link to one of those as well.

What is the max current this unit can handle?
There doesn't seem to be any official specs anywhere about this, but usually 12V cigarette outlets are rated for 10A. This outlet seems to be physically quite similar to most other 12V outlets (at least, in terms of the size of its contacts), so I'd say that 10A would be a safe limit for it too. You might be able to get away with 15A or 20A, but that might start melting it, depending on ambient temperatures.
