20 amp to 50 amp question

When I bring the RV up to the house from our non powered storage area here at our HOA to do routine biweekly service, I need 110 power for the TV and satellite box. I have been using adapters to go from household 20 amp to 50 amp so that I can service and boot up the Satellite box and TV. Does any one see a potential problem. All I'm running while doing this is the TV and a floor fan for circulation.

Shouldn't be a problem, other than possibly tripping a breaker if the current draw is excessive. With the load you describe, I would think you're fine. Our 50 amp RV stays plugged into 30 amp service while in storage.

As mentioned, not a problem. I just make sure the connection will not get wet laying in a hole in the grass.
If you do anything that will draw any where near 15-20 amps get yourself a heavy duty extension cord. 12 gauge will work 10 gauge is better especially if you will run a heater or AC in the summer.
I melted one and I an suppose to know better.

I assume that battery charging is part of your load? It can be quite a few amps if the batteries are low. It might pay to monitor your draw with an ammeter, kill-a-watt, etc.

Also check for excessive heating of your extension cord and plug/socket.

No ptoblem--a heavy duty 20 amp cord would be good, especially if you are running more than 20-25 feet of cord. As mentioned, the battery charge [inverter] and the hot water heater can be large "hidden" draws.

Agree it's not a problem. On 20 amp I can use lights, Fridge, TV and usually 1 AC, or just the microwave. alone.. ( We plug in this way visiting our DD)
An easy check is to look at the voltage drop. As the load increases the voltage at wall sockets in the RV will decrease. Approaching 108 volts you are putting a strain on motors and controls, they won't like that for very long...

As mentioned the converter/inverter will draw several amps in cycles to charge the batteries and you have no way to know that's happening.
