Deciding on a suitable appliance, particularly a mini-refrigerator, when you are getting ready to send your son or daughter to college, isn’t all that simple. It’s a bit more complicated than just driving to a nearby appliance shop and purchasing the most inexpensive mini-refrigerator you see.

These days, a few rooms in college dorms may already have a mini-refrigerator available, and if so, there’s no reason to bring one yourself. However, sadly that’s not true when it comes to all available rooms in a college dorm.

Prior to going to the appliance shop or looking on the Internet to find a mini-refrigerator, you should talk to the college and see if they’ve got any rules or regulations on what’s allowed. A lot of colleges limit appliances to those that run on 120 volts and have lower than two amps. I guess that’s done to reduce the dorm’s electrical consumption. Regrettably, not every mini-refrigerator displays that data on the box, so that means you must do a bit of research on your own.


As the world is advancing in technology, everything is evolving to become better and more convenient. Mini fridges, also known as compact refrigerators are mainly used for storing food and beverages. Mini fridge requires only a small limited space that provides you with the convenience to place one in your bedroom, home offices, garage, kids room, or wherever you want.

You may be surprised to learn that mini-fridges use less energy than conventional refrigerators, simply because they are smaller. When you think how many watts does a mini fridge use, logic says it should be small. But that is not always the fact.


The difficulty in estimating the energy of the refrigerator is that, although the refrigerator is always “ON” but it is not always “working”. The compressor in the fridge goes on and off, and there are many factors that affect how often this happens. Setting the temperature in the fridge, the amount of food inside, the frequency at which the door is opened, and even the room temperature makes the compressor stop and start the cooling cycles.

Compact refrigerators, or mini-fridges, are primarily used to store foods and drinks in dorm rooms, game rooms, home offices, garages, and alike. Thanks to the fridge’s humble profile, they have a very limited space requirement so you could conveniently place them anywhere you see fit. Nonetheless, you are in for a surprise if you assume that mini-fridges use less energy compared to standard fridges simply because they are smaller.

Want to know how many watts does a mini fridge use? Then you could find the answer right down below along with a couple of important information on the side.

What is the cost of running the average mini fridges?


Here is an interesting fact: For most of the time, mini-fridges actually use more electricity per cubic feet than other standard size fridges. The cost of running a full-size refrigerator is only about twice as much as a compact fridge one-quarter of its size. As a result, a 4.4-cubic-feet compact refrigerator could cost you $27 a year while a much larger 20.6-cubic- feet fridge only cost you $47 in the same time period.

There are two reasons behind this: First, there isn’t a lot of room for insulation. Second, mini-fridges have considerably more area per cubic feet to accommodate food and beverages which require additional electricity to keep everything cool. Of course, there are many other contributing factors too such as the unit age, the room placement, the defrost setting, and so on.

In general, provided that the setting is similar, mini fridges would have lower energy efficiency compare to full-size refrigerators. Most people don’t notice the slight difference in their utility bills though because compact refrigerators often cost you well below $5 per month. To have cold snacks and beverages in your hand while watching sport or playing games could easily justify the less than ideal efficiency.

You should be able to find an eye catchy yellow and black Energy Guide Label somewhere on the fridge body. It would tell you the estimated amount of energy the refrigerator could use in a year along with its projected c cost. Products with an Energy Star rating on their label tend to consume less energy compared to other models.

How many amps does a mini fridge use?

The refrigerator ampere is often listed in the manual or on the fridge front/back labels, you could even look for it online. It’s also simple to manually calculate the ampere of a mini-fridge, you only need to use this formula: Amperage = Watts/Volts. For example, if you have a 120 Voltage and 240 Wattage then your mini-fridge shall have an Amperage of 2.


With all this data, it appears that the majority of mini-refrigerators need about two amps, so are an allowable appliance at most colleges. If you aren’t certain on how to apply the formula to find how the number of amps your mini-refrigerator needs, then it’s a good idea to check the manual for it. That info is normally listed at the beginning of the manual or at the end.

A lot of them additionally put this info on the box. But if you are buying a second-hand mini-refrigerator and don’t have either the box it came in or a manual, sometimes you can find that info on the fridge compressor via a sticker. But if you’ve tried all that and still do not know the answer, just ask your college to give you some recommendations.

How many watts does a fridge use?

When it comes to household appliances, refrigerators use the 2nd most energy amounts after air conditioners. The US Depart. Of Energy reports that the typical refrigerator utilizes about 725 watts of electricity as well as between fifteen and twenty amps. That equals about ten percent or higher of most electric bills. Considering that, it’s logical for universities to put a restriction on what kind of appliances they allow in their dormitory rooms, particularly the type of refrigerator.

Watts consumed by the fridge rely on the utilization and on factors like model, size, and age of the unit. That’s why the amount of electricity differs with each model. Freeze, uses an electrical motor-driven compressor According to Tom Hanson, editor of you can calculate how many watts a freezer uses? By checking tech specs and assessing the merchandise manually.

Knowing the meaning of an appliance’s electrical requirements and conditions is the initial step you should do to make sure you buy the right mini-refrigerator.


The wattage calculates the rate of energy that gets turned into electricity, typically per hour. A mini-refrigerator ought to have a label on it that states its energy consumption rate in wattage. This wattage gets calculated in Watts, which can be used to determine a mini-refrigerators amperage.


Once you know the fridge’s watts, it’s possible to determine its amperage. The amperage is equal to the appliance’s wattage divided by its voltage, via this formula: Amperage = Watts/Voltage. Voltage is regulated in the United States and every house comes with 120 voltage.

Considering the reality that every house in the US runs on 120 voltage, any type of mini-refrigerator which has wattage going up to 240w falls into the less than two amps limitation the majority of universities have. The majority of mini-refrigerators have Energy Star technology. This is a type of technology that saves energy and thus lowers the power usage of the mini-refrigerator.

How Many Watts Does a Mini Fridge Use

In general, the energy used by a mini-fridge is measured in watts. Most of the fridges use almost 80 to 100 watts per operating hour but it can vary depending on its brand, size, and many other factors. If a fridge consumes 80 watts in an hour and runs 8 hours a day, then it will use almost 640 watts every day. As residential electricity consumption is measured in kilowatts, it will be 0.640 kW per day and 234 kW per year. The average electricity cost is considered as 13 cents per kilowatt which will result in a $30 annual cost of running a mini-fridge.

Keep in mind that price can vary greatly depending on the local electricity rates as well as individual preferences. It is recommended to compare different brands and choose the best one for your house or office. There is a comparison of two brands that are just examples, there are more manufacturers in the market to choose from. This comparison will help you get an idea about some top brands and the energy consumption of their fridges depending on their size.
