How many amps does a mini fridge use.
Mini fridge amperage draw.
Well that s the on an average story of how much amps the rv refrigerator draws.
In the example below the lra is 5a 5 amps which would be equivalent to 575 watts for startup for a unit plugged into a 115v outlet.

It s also simple to manually calculate the ampere of a mini fridge you only need to use this formula.
Remember about a safety margin of 20 30.
The startup amperage draw rating will be noted on the compressor itself by referring to the locked rotor amp aka lra value.
On an average a running refrigerator will need around 2 4 amps.
Lower wattage models can range between 85 to around 100 watts while running 4 but many mini fridges can go up to 250 watts 5.

Wattage measures the rate of energy converted to electricity usually per hour.
For example if you have a 120 voltage and 240 wattage.
Place a mini fridge in the.

To get the watts you would multiple the volts by the amps.
Please refer to a photo of the compressor labeling for model crf150ss 1 below.
The formula for converting watts to amps is watts divided by volts amps.
A refrigerator will use roughly half of the available amperage of a standard 15 amp circuit and over one third of a 20 amp circuit.
Once you know the refrigerator amps and volts you can figure out the watts.
According to consumer reports testing annual operating costs for the most efficient 4 4 cubic foot mini fridge can be as low as 27 while a much larger 20 6 cubic foot refrigerator costs just.
