Open Question: plug in cords for camping (blowing up matress)?

They have regular electrical outlets for basically everything, and then they have outlets in your car right? (for cellphones and stuff. I bought an electrical air pump for a camping mattress and I assumed it would be made for the car outlet, however it is for a regular outlet. I did not bother looking at the box closely because for some reason I did not think they would make one if it was for camping. Anyhow, can you buy extension cords to plug into the car that will convert a regular cord? For example can you use a truck outlet to somehow use a hairdryer or something? Do they even exist?
