Wire gauge for lighter style plugs

I am planning to add 3 lighter style plugs to get power for my tsunami pumps(1 per bag) closer to where I place the bags so I can stop using an extension from the dash one bag at a time. Any ideas what gauge wire I should use if I wanted to run all three from the same battery connection?

12ga, unless you're like 20' from the battery.
