Listing of AMP usage?
Happy Father's Day! Getting closer to taking shakedown trip with new to us fiver. I need to find a listing of AMP usage for appliances/equipment. Living in Florida means the A/C is a must, so I n...

Hi,
You can check the amp draw of many things, and it is molded into the plastic. If you can not read the number, the eyes of a grandchild can help. It is typically tiny and in the plastic.
So the coffee maker might be 1,000 - 1,200 watts, or about 10 amps
toaster can be 8-10amps.
Microwave might say 900 watt output power, but typically will have 1,200 watt input power or about 11 amps
A/C units are about 11 - 14 amps each, with warmer days increasing the amperage.
On the RV, the refrigerator is about 3-3.3 amps, and practically nothing if running on gas - bonus is the gas cooling effect is almost double the electric heating element cooling capacity.
Battery charger is going to be around 1-2 amps, more at night when more lights are on.
TV is typically less than 1 amp with a LED screen, still a small load. VCR, DVD or laptop computer are all less than 1 amp each.
If you have a 30 amp service, then you might be able to run 2 A/C if you shut off most everything else, and only run the TV. While away from the RV, my suggestion is to only run 1 of the A/C units, because you will not be there to reset the circuit breaker - should it trip under a heavy load.
Also in some campgrounds it is a requirement to monitor the input voltage, and stop the A/C if the voltage is below 104 volts. Most will plug in a autobooster if below 110 volts, to bring it back up to the normal range. At 104 volts the A/C compressor will be drawing more amperage, and might trip on it's internal overloads. IT can also damage the expensive to replace compressor if running less than 104 volts!
Good luck!
