What size power inverter
#21
150Watts /120 Volts = 1.25A
Looking at Dodge.com, they say it's a 400Watt invertor. If the outlet is labelled 150, I wonder where you can tap into the full 400W?

If you are looking for something the run power tools would you really look inside the vehicle. I am surprised they all don't have a good heavy duty plug in the back of the bed no matter what model. That, would be handy.
The cab is like an office very comfortable roomy, tons of space for anything you want, people say noplace for sunglasses, try the door panels,,,mine even have drink trays in the doors. All kinds of little storage if you have the console truck, crew cab I think they advertise 43 or 48 places to put stuff

3000 watts/12 volts would require 250 amps .......
that would tax the alternator somewhat..... cough cough..
for that kind of power a separate generator is your best option not to mention the ability to move it where needed. The quietest one I have seen is the honda you can have a normal conversation standing right next to it

Well thanks for the input guys. Maybe some of the really big tools are a pipe dream. I know I've seen a truck running an air compressor and a table saw off the truck at a construction site (not at the same time), but he must have had a high output or dual alternators. I never was able to find any hard evidence of my alternator output, but I've seen a couple 2009's for sale with 5.7 hemi's claiming 160-amp alternators, so 160x12 would equal 1,920 watts, so I guess I have found the answer to my question, probably a 2,000 watt inverter would be the biggest one that would be useful for me. Which is handy to know. I did find a few places selling 250-amp alternators that would get me in the 3,000 watt range, but they're pretty pricey, so I doubt I'll go with them. I would think a bigger alternator might reduce fuel economy. Anyway, thanks again. If anyone comes across a concrete number for the amps on the factory 5.7 alternator though, I'd love to know. Thanks.

If you want more power, and it seems you do, you should consider an under-hood generator

I know most of my saws and other tools use 20 amps. I think the main purpose for the a/c outlet is for a laptop and maybe some hair dryers, but they are definatly not for power tools. Tools will also require amps that are variable, like a large load (when your saw gets stuck in roughcut oak, and the legnth of your extention cord (the longer it is, the more amps it will need to draw). By the time you invest in making your truck able to run power tools, you may be able to buy a small generator that won't fry your wires and catch your truck on fire.

120 volts divided by 150 watts = 1.25 amps. I was wrong when I used 12 volts as the multiplier. Sorry for the bad info. It's corrected now.

12.5amps is the load that the battery/alternator sees, not how much current it provides on the 115/120VAC side.
