If your RV is 50 amp. using one of those adapters you can get (depending on the adapter) 45/2 50/2 or 60/2 amps.. Why do I keep saying /2
Well 50 amp service is 50 amps TIMES Two.. That is two 50 amp legs. Now I can give you the technical reasons for doing this but please just take my word there are good reasons.. that's 12000 watts
The most you can get with a 30/30 adapter is 7200 watts and at that there is risk
Second, as others have said if either outlet is GFCI protected (And I've seen 30 amp outlets so protected) Click of darkness ensues as soon as you plug in the 2nd plug
Finally
the power in a 50 amp RV is "Divided" you actually have two 120 volt systems, we usually call them L-1 and L-2.. ideally for example the Kitchen and one A/C are on one leg (Does not matter which, L stands for Leg by the way) the other A/C and the water heater on the other. remaining outlets are also divided between them
The adapter gives you 30 amps on one leg
And whatever the other plug is connected to on the other leg
DO THEY WORK?
I have one campground where it's all 30 amp outlets. about half of them are GFCI and no it does not work there.. The other half are NOT so I use one of the 30/30 cheater box devices, works great
I have one where there are a couple sites I can do the same thing.. But only a couple of sites
I can run nicely on 30/30 30/20 I have to be very careful but on 30/30 I'm good
