The outlet in the bed is 12 V DC. To run 110 V AC you need to use an inverter. Depending on amperage, it may need to be wired to the battery with heavy gauge cable.

so what exactly can I plug into the outlet?

The one right now? Anything 12V.

 

Within the limits of the fuse for the circuit. (which I don't know, never have used mine).

 

It only works when the truck is on right?

 

No it's always hot

You can plug in a spot light an inverter , an air compressor or other 12 volt accessory.
I've never even touched mine in the two plus years I have the truck.

I believe this circuit is protected by a 10 amp fuse.

 

I checked the spring loaded cover on mine and it says 12V, 20 AMPS maximum. If you wanted to plug in an inverter, you'll need to keep it to under 240 watts or wire it direct to the battery with heavy gauge cables as the one guy recommended.

I use mine all the time for lights, and a fridge/freezer I carry back there. Pretty slick little feature if you ask me.

I keep telling my friends to use it to charge their cell phones...of course not while we're driving...
