I am not sure what you could do with a 100w inverter but back in the day you weren't able to power or charge everything with your cigarette lighter.

I have a have had a 400w inverter in my jeep since I bought it in 2001. It is mounted under the passenger seat. I works to charge batteries. I have used it to run lights while I set up camp. I have used it to power items when power has gone out at the house. I have even used it to power a weed eat out in my field (didn't work so well so I bought a gas weed eater). Having a n inverter just gives you options that may or may or may not be useful to you.

 

A power inverter typically converts the Jeep's 12 volts DC to 120 volts AC like an outlet in the house provides. But 100 watts capacity isn't really enough to do much with, I wouldn't bother installing it.

 

RATS!!! So much for my daughter blow drying her hair in the back seat Good thing the doors come off

So if I do mount it, it would really just be extra USB outlets for phone chargers. What would run on 100w?

 

It is 100W on the cig lighter, but 1000W if wired directly to the battery, so as long as your blow dryer is less than 8 amps, it will work. It will charge laptops and other low draw (8 amps or less) devices.

 

A 100 watt inverter can only provide 100 watts max (8 amps) to its 120 vac outlet no matter what. And whatever the amperes it is providing at its 120 vac outlet, which is roughly 8 amps at 100 watts, it needs to pull 10x those amperes, 80 in this example, from the Jeep's 12 volt DC battery system. So no, it can't even come close to providing enough power for a high power device like a hair dryer which typically requires 1300-1800 watts of power. And no, her hair dryer couldn't be connected directly to the battery.

 

Did you click on the link? The inverter is 100W when plugged into the cig lighter and 1000W when hooked directly to the battery. Also 100W is .833333333333333 amps at 120VAC

 

I can't get the link to open but many inverters advertise their peek power and they can not run for more than a moment delivering that power.

 

The link states that the 1000W rating is continuous power. Peak momentary output for that unit is probably around 1200-1300W.

 

To the OP: not sure if it's a viable location for you in a JK, but I hard mounted an inverter in my TJ on the outboard wall of the passenger side foot well. I also have an inverter for my LJ but haven't gotten around to mounting it yet, so it normally sits under the driver's seat until I stop somewhere and can hook it directly to the battery posts. They're not exceedingly useful for day to day life and short commutes, but they come into their own on road trips and when camping -- mine are most often used for powering a 5 cup coffee maker. :tea:

 

I have a 400W one I bought many moons ago. It was used for long trips powering devices to entertain the kiddo's.

Now I use it camping when I don't have AC available for charging phones, radio's etc. I also used it in the Jeep this year to run the Christmas lights that were 120v.
