Just think about this for a minute. The A/C outlet is being powered by the same battery, alternator, wiring, etc. as the 12v "cigarette lighter" plug. Why in the hell would you even expect it to handle a higher capacity than those types of plugs? The A/C plug is simply a convenience so you don't have to purchase an inverter/adapter.
Think about how thick the wires are on an extension cord that is thick enough to be approved for power tools and/or outdoor use. How realistic is that for the wiring inside your truck? I've seen no passenger vehicle by any manufacturer utilizing a plug with any higher capacity.
You want to run a power tool off of a 110v plug in your vehicle, then buy a damn motor home that has a generator on board. Even at that, it better be a good size generator. I own two portable generators, one a small, tool box size portable for camping use (without going out to my shed and looking at it, I believe it's a 1500 watt peak, 1000 watt nominal unit) and the other a huge, hundred and a half pound 14 HP, 7000 watt model. The small generator will NOT power a simple skill saw without tripping it's own circuit breaker.

Why would you expect a portable air pump to work on the 110 outlet? Well maybe because you can buy about any airpump in the automotive dept that works fine on the 12v outlet, which would leave one to believe a small b&d air pump could also work on the 110 outlet just fine? Eh?

Home air compressors are more heavier duty than portable one's because they have a bigger motor. The motors require a heavy start-up current that cannot be supplied by the Trucks AC outlet. Home electrical is either going to be 15A or 20A supplied current. The truck can only supply just over 1A continuous. It cannot handle the spike needed to get it up and running even if the continous supply of the compressor only needed 1A. It is this reason there was a blub, blub like it struggled to kick over. There just isn't enough current to get the job done.
You can certainly install a bigger inverter to run a compressor, but you need to stay within the limits of the circuit(Cig lighter is 15A) There's still a limit on what you can do. Power equip. is a no-go.
I wouldn't think ANY heat source element such as a crock pot or even a small heater is too much for the outlet as well. Things like a miniature TV, maybe a back massager or a laptop and that's it.
110v has no direct coorelation between a 12v supply. It's all about the current, not the voltage. So saying a 110v should be capable of supporting 12v is not how it works. Beside's, 12v is DC and 110v is AC. 2 completely diff. power sources.
