How much juice?
Hey guys in my 97 4x4 4.6 I have a few electrical accessories and I am just woundering how many more I can push. I have the 1 12v dc plug factory, 1 cig lighter factory, I added another cig lighter and put that behind the dash so I could run my satellite radio wires all hidden. The cig ligher I added and hid, I just jumped it off of the fuse from the factory cig lighter. I have a streamlight flash light charger mounted by the cb. I have my cell phone charger. My cb is jumped off of the fuse for something else not sure what it is b/c I did not put it in. For my bday a friend bought me a 12v heated/cooled cooler for my truck and I want to run another cig lighter to the back of the cab and semi permanently mount my cooler.
I also have 2 100W driving lights ran directly off of the battery.
Basically at max capacity here is what I will be running.
Sat radio
Flash light charger
cell phone charger
electric cooler
CB radio
2 100W lights
Is this starting to get kind of high? How much more power can I pull? How do I run a new power line to the fuse box and utilize some of the unused fuse plugs instead of keep jumping off of something else?
Thanks guys

a Watt is a volt x amp. 100 watts at 12 volts is about 9 amps load. an 18 guage wire will be good for 10 amps... that being said, your chargers dont pull 1 amp. you could probably run a dozen chargers off the cigarette lighter plug.... the radio im not sure, but probably 8 amps, and the lights pull 9 amps each. if the electric cooler is 100 watts then it pulls 9 amps. you can see you are approaching 35-40 amps. thats not a bad load, you alternator can do it. probalby is you should not run all that off a cigarette lighter. the two lights should have a 12 gauge wire from a 20 amp fuse (to run both). the cooler and radio might run off the cigarette lighter if they are smaller than i guessed. might be good to run alother 20 amp fuse with a 12 guage wire for them as a pair also. you can buy a double or tripple fuse block at aouto zone and just supply it with a new 10 gauge wire from the battery to the new block under the das. run 2-3 different cigarette plugs to the 2-3 different fuses. might be easier than getting into the original fuse box.

Yeah sounds like a plan. I think the cooler is 60Watts.
The lights are completely separate from everything else. I ran 10 guage wire from the positive battery lead to a 15 amp inline fuse to a switch, grounded the switch then ran that to the lights and grounded each light. I think I am going to try and figure out a way to make a little area for it to fit in between the drivers side of the back seat and in between the non existent door and then run a dedicated cig lighter straight to it off of the battery, or maybe even put 2 or 3 plugs in the back there with it and run them straight off the battery.
Thanks Steve, that is the info I was lookin for!

You should be alright. My stereo is pushing 52 Watts to each speaker (4), and I gotta 4 gauge power wire running to my 700W amplifier and to a 12" sub. I am also going to add two, 35 Watt fog lights to the rear of my truck and wire them up to a switch for backup lights. My alternator's got a lifetime warranty, and my battery has a 5 year warranty. I'm not worried! Haha....
