An RV outlet at a state park could have 3 different plug outlets, and you can use all 3 on almost any camper if you have the correct adaptor.
However, the amount of amps that you can use in your camper at one time will depend upon the fuses or breakers between the power source and your camper. The pedestal at the campground will have 15-20 amp plugs, 30 amp plugs, and/or/maybe 50 amp plugs. But all 3 of them are only 110 volts. None of them are wired for 220. Unless you have a household stove/oven/water heater/or cloths dryer in your RV, you will not use 220. Everything in your camper is 110 volt. The number of amps is determined by the main breaker is your breaker box / converter.
As said, you can run pretty much anything on a standard 110 volt 15-20 amp circuit inside your camper, but you may be able to run only 1 "thing" at a time. If the over all usage exceeds the breaker 15 or 20 amp setting, it will simply pop. Turn something off, reset, and it will be fine. For example, running the air conditioner with a hair dryer and the microwave will most assuredly pop a 20 amp breaker.
So, power management inside any RV is simply a way of life. You learn real fast what you can run on electricity all at the same time.
There are adaptors you can purchase that are pretty standard. There are basically 2 types. One is called a "dogbone" and the other is called a "puck"
Below are a couple images of a dogbone and a puck. One is an adapter for 30 to 20 amps (standard RV plug to household plug). The other is a 20 amp to a 30 amp. (Standard household plug to an RV plug).
Notice the pattern of the male plugs. The 20 amp household plugs have the straight flat pins that are parallel with the ground being a round pin.
The RV, 30 amp plug also have 2 flat pins, but are in a V shape and the ground is a round pin. These are designed so the wrong one cannot be plugged into the wrong power supply, especially plugging an RV into a 220 volt system.
Puck 20 household to 30 RV:
Dogbone 30 RV to 20 household:
Depending upon the type of unbilical cord your camper has will determine what you kind of adapters you'll need, if anything.
Some older campers have the normal 20 amp amp male plug. If yours is this way, you don't need anything. Just plug into any household plug.
One thing I made sure of, was to have the right combinations of adaptors to go either direction up to a 50 amp plug, especially considering my 5er is 50 amp.
What is always safe to have are the following:
50 RV to 30 RV Dogbone
Male to female
30 RV to 20 Household Dogbone (or puck)
Male to female
20 household to 30 RV
Male to female
30 RV to 50 RV (If your camper is 50 amp).
Male to female
Here's a photo of a typical RV power supply box found at campgrounds showing all 3 types of plugs: 50 amp, 30 amp, 20 amp.
Remember, all these are 110 volt.
A 50 amp may be 2 legs of 110, but it's still only 110 because of the way they are wired, not 240.
