We have lighter plugs straight to the fuse block with heavy wire, and carry 10' jumpers in 10 gauge wire. Got heavy lighter plugs and we can charge our bikes, jump our bikes, or jump someone else off of our bikes without removing the seat or battery cover. Just use heavy wiring. Also, think about what you will be plugging into the port -- if you're charging your cell phone it's nice to have the port situated where the charger cord isn't hanging where you can trip over it getting off the bike, or have it end up against something hot while you're riding.
