Warning: this is my personal opinion which may not be shared by all.
I hate any compressor that merely plugs into a cigarette lighter type outlet.
Compressors that function with these connections are usually small and take forever to pump up a regular passenger car tire running 35 PSI max.
When talking RV tires, the starting pressures are usually 50 PSI and often go over 100 PSI. Any compressor that will do a good job, in a reasonable amount of time, draws far too much power for a standard "cigarette lighter" receptacle.
I have a small compressor that connects directly to battery terminals. Only complaint I have is that the hose is too short so I have to drag the compressor under the trailer to reach tires on the far side from where my batteries are located. My plan is to permanently mount the compressor in an unused corner of my storage area which is right next to where my batteries are mounted. This will allow for a short run of wire to the battery power bus and then just get a longer hose. One that will reach all the way to my spare or even the farthest front tire on my Tow Vehicle.
Need air? Open compartment, turn on compressor, connect hose, inflate, turn off, stow hose, continue. This will also give compressed air cleaning small parts etc.
Compressor is already stored in the same area, only difference is that it will be screwed down and available at a moment's notice with no need to remove it from it's bag.
Here's the compressor I have and it draws 30 amp at full pressure. Way too much for a power outlet.
Bought mine at O'Reilly's.
