12vdc Cigarette Lighter Question

Hello

The original cig lighter in my boat needs replacement.
I use it for ipad, cell phone etc.

I am buying a dual outlet today.
Can I just pigtail from one to the other?

Thanks

Re: 12 volt cigarette lighter question.

Yes. You can parallel it with the other lighter using the same gauge wire and keeping the existing fuse or breaker that protects the circuit. The total current that can be drawn will still be the same but for the little amount of current that a cell phone and iPad charger draws, that will not be an issue.

There are also cigarette lighter splitters in case you don't want a dual outlet.

Re: 12 volt cigarette lighter question.

Short answer, yes you can. But, would not a dual outlet already have both outlets wired together? If not and you have to wire them together the only concern I see is to make sure that the wire sizes will be adequate to carry the max loads you plug into the outlets.

Re: 12vdc Cigarette Lighter Question

i bought some multi-stack connectors.

Re: 12vdc Cigarette Lighter Question

Be careful if making any cuts or splices - polarity counts.

Yes, + goes to the center pin on both outlets.

THX, xymotic!

Yes, polarity must be correct or else bulbs will work, inverters will not ;-)
