RV Info – How much Current do your RV Appliances draw?

The typical RV has either a 30-Amp or a 50-Amp Service.

This can really limit you at times when you are camping and using a lot of your appliances. The result of this will usually be a thrown breaker, either in the Camper, or at your campsite service box.

In order to avoid such a dilemma, you should be aware of how much current your appliances can draw and plan your day avoiding using too many electrical devices at one time.

The table below lists the typical current used by must standard 110-VAC appliances.

Air Conditioner (Startup Current)-     12.5 Amps

Coffee Pot, Electric-                                   9 Amps

Crock Pot–                                                        1 to 2 AMps

Food Processor–                                             8 to 10 Amps

Frying Pan (Electric)-                                 8 to 10 Amps

Hair Dryer–                                                    10 to 15 Amps

Iron–                                                                   10 Amps

Oven, Microwave–                                      10 Amps

Refrigerator (2-door medium)-            2 to 4 Amps

Toaster–                                                           8 to 10 Amps

TV, Digital-                                                      1 to 2 Amps

Vacuum (Dirt Devil Hand Unit)-          2 Amps

Water Heater, Electric (6-Gallon)-     8 to 12 Amps

These numbers are average numbers and vary by type of appliance, but you can see how they can add up and you can exceed your breakers current capacity if you are not very careful.

NOTE: Typically, the lights in your Camper are 12-VDC and operate on your RV’s 12-Volt batteries. But, remember, that at times, if your batteries drop below a certain limit of stored charge, your AC/DC Converter/Inverter will kick in and can draw some significant current as it charges your batteries back to their normal level.

  1. Can you convert the 50 amp to a 110 amp and use an extension cord to plug in extra appliances ie( electric frying pan and toaster) We use the 30 amp hookup for our camper. We are constantly blowing fuses.

    1. Julie – I guess you mean 110-VAC. Actually you can purchase a couple of adapters at your local RV parts store. they make one that adapts the 50-Amp conn. to a 30-Amp receptacle, and they make on that adapts the 30-Amp conn to a 15-Amp receptacle. I use these when I am in a campground that only has 30-Amp service, and often when visiting people’s homes that only have a regular outside receptacle available for me to use.
      So, if you are connected to the 30-Amp service with your RV you can use these adapters to supply power to an extention cord.
      Good Luck,

    1. Check if it has a wattage rating on its label.
      If so divide this number by the AC=Voltage, or 120 VAC.
      So for a simple example, a 1200 Watt Ice Maker would draw 1200/120 or 10 Amps.
      Try this for your maximum Wattage rating number for your Ice Maker.

  2. can I use the parking light circuit on tow vehicle to keep battery on towed vehicle charged while small RV regrigerator is operating?

    1. That’s not recommended. For one thing, while on the road, your parking lights are not lit. Usually when being towed, all towed vehicle power is turned off. and the brake/tail/signal lights get their power from the towing vehicle. So, without more information, I assume you have a small fridge you want to put into your towed vehicle and you want to power it from the towing vehicle while on the road. The problem is always going to be just how much current does this fridge draw. In my opiion,if tit draws a maximum of only a couple of hundred milliamps, then the wiring can take it safely. If it is much higher than this, the wiring could overheat and the insulation could melt causing an electrical danger. Good Luck! Don
