AC plugs won't power laptop

Just wondering if anyone else has tried to power a laptop off either AC outlet? I can charge a cell phone off of them, but that's it so far. What gives?

I suspect the inverter's AC output is a "modified square wave" (MSW) rather than a true (or pure) sine wave like you get from AC wall outlets at home of from a high-quality TSW inverter. Some chargers (and other devices) aren't really compatible with MSW.

Check the laptop charger instructions and/or labeling, and try another "simple" load, such as a regular ol' 75W light bulb.

I believe you are correct. I read this somewhere else when I was having the same issue with my (now sold) '15 F350.

I run my work lap top on mine all the time (Older HP Elite Book). I have a new one coming. If I have issues there I will report back if there is some compatibility issue with the new charger.

This sounds plausible. I came to the conclusion it doesn't play well with smart chargers.

I pulled the UPS out of my office and tried to run it on the 120v AC in my F-350. No joy. So far, the ability to run only certain things isn't a huge problem. But if I find I need that power then I'll look into changing the inverter.

The 360* camera system uses the inverter. I can't imagine why it wouldn't work with a better inverter, but stranger things have happened....

I haven't had any issues charging camera or quadcopter batteries, or laptops. I want to put a meter on it now, though.

manowell, what quadcopter do you have? My AC plugs won't charge my DJI Phantom batteries at all.

Ford has the most powerful inverter currently available, at 400W. So if it doesn't work, a RAM or GM won't work either.

everyone understands the outlets only work when the truck is running correct?

I have no problem using, and charging my MacBook pro's (85w) using the AC outlets.
Laptop chargers consume less than 100w these days...and they do NOT need a purse sine wave inverter.

laptops (and even flat screen TV's) have their own internal/charger power supplies which condition the power....modified sine wave inverters work fine.

Mine wouldn't run my laptop either, I was thinking there was something wrong with my receptacles in the truck but now it just appears to be some sort of crap design.

It has to do with the QUALITY of the power, not the QUANTITY. Voltage plays a part too. If the voltage isn't high enough, many things simply won't work.

ok for those having issues, have you measured the voltage coming out of the outlet?
