If fuses are ok, then check your auxiliary power outlet with voltmeter. If it reads no voltage then try to remove and unplug the outlet - good luck!
Once you removed the outlet disconnect the wires and read voltage off them, if it reads ~12- 13V then everything is fine and there is no internal damage in wiring. Just need to replace the bad outlet which is cheap.

I was in a similar situation, my portable tire inflator caused both of the 12v power outlets to melt inside. The fuse was ok, but there was no power. At first, I thought the entire wire from underhood fuse box to outlets blew and I had a major problem now. But turns out the inflator was overheating the ports and damaging them.
