# How many watts does a modern fridge use?

Modern refrigerators are very energy efficient compared to older models from a few decades ago. A fridge will use anywhere from 100 to 400 watts depending on size, a large fridge will use about 180 watts or 1575 kWh annually.Click to see full answer. Thereof, how many watts does a refrigerator use per day?Domestic fridge power consumption is typically between 100 and 250 watts. Over a full day, a fridge is likely to use between 1 to 2 kilowatt-hours (kWh). This translates into a running cost of about \$150 per year per fridge.Secondly, what size generator do I need to run a refrigerator? For example, if you want a generator to run a refrigerator and a freezer, the wattage (table 2) of the refrigerator would be 800 and the freezer would be 1,000. To select the correct size generator, you decide if both refrigerator and freezer are to start at the same time. If so, you would need (1,800 X 4) 7,200 watts. Similarly one may ask, can a 2000 watt generator run a refrigerator? Speaking of which, one of the most common appliances, either in an RV or at home, that you are likely to always want to be able to power is a refrigerator. Luckily, with a 2000 watt generator, you can indeed run a mid-sized refrigerator as long as its energy star rated and uses no more than 1200 of starting watt power.How many watts does it take to start a refrigerator? Calculating Average Wattage for Refrigerators Older refrigerators typically use 115 volts and 7 amps, which you can multiply to find a use of 805 watts. Conventional refrigerators typically have a starting wattage of 800-1200 watt hours/day, and a running wattage of around 150 watt hours/day.
