In this article, we’ll explain everything you need to know about buying an energy-efficient mini fridge. So, let’s get started! 

What Should I Look For When Choosing a Mini Fridge?

When buying an energy-efficient mini fridge, check for an Energy Star rating and specific energy consumption. A good rating ensures you choose a model that minimizes energy use and maximizes savings. It would be best if you also compared brands and models to choose the most efficient mini fridge. 

How To Choose an Energy-Efficient Mini Fridge 

When choosing a mini fridge (or any appliance), price and features are the first things people check. However, the appliance’s energy efficiency is also vital.

As long as your mini fridge is plugged in and functioning, it will consume energy. This energy will cost you money and impact the environment, so selecting a model that operates optimally while using the least amount of energy possible is best. 

Here’s what you need to consider to ensure that your mini fridge is as energy-efficient as possible:

  • Power source
  • Brand credibility and stance on energy efficiency
  • Energy Star rating
  • Date of manufacture
  • Recyclability of materials 
  • Refrigerant used 

Now let’s consider these crucial factors in more detail.

Power Source

Natural gas and electricity are two popular options for a mini fridge’s power source.

An electric mini fridge requires you to plug or attach it to an electric source to use it. Electricity is the most conventional type and most energy-efficient. The downside is you cannot use it during power interruptions. 

On the other hand, a mini fridge that runs on natural gas is used for models that use ammonium refrigeration. A natural gas fridge might need a gas line, but that also means you can use it during power shortages. It also typically offers cheaper running costs, less pollution, and fewer gas emissions. However, it may need more maintenance.

Other power sources for mini fridges include the following: 

  • Propane
  • Kerosene 
  • Butane

Like natural gas, these sources power mini fridges that run on ammonium refrigeration.

Brand Reputation

After deciding on a type of mini fridge, it’s a good idea to research the various brands. 

When considering brands, focus on ones with a reputation for: 

  • Durable and high-quality products
  • Excellent customer service 
  • A solid stance on environmental issues
  • Transparent on materials and coolant or refrigerants used 

While choosing a durable and good-quality fridge is a given, other factors are also important. 

Here’s some greater detail:

  • Excellent customer service – customer care is crucial if you need to contact the company about a faulty part soon after purchase. One way of determining how a brand handles customer service is to check online reviews. 
  • Environmentally friendly – traditional refrigerators contained harmful chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), two greenhouse gasses contributing to global warming. Newer fridges use eco-friendly coolants like R600a instead. 
  • Transparency on parts and materials used – companies consistent with their environmental stance and transparency are more likely to be upfront regarding the materials they use in their mini-fridges. 

Energy Star Rating

An Energy Star rating is awarded to a mini fridge model that is at least 20% more efficient than others. However, even amongst Energy Star models, specific energy consumption rates vary. 

When buying a mini fridge, look for the Energy Star label. It will contain information on features, maker, and model size. However, for comparison purposes, you should check the estimated yearly operating and electric costs. 

These two details will help you assess how much your fridge will cost you in the long run. This figure is an essential consideration because some models may appear cheap upfront but will rip you off in the long run due to high electricity consumption. 

Model Age  

After you’ve chosen your ideal model, it is a good idea to check the manufacturing date.

Newer models tend to be more energy-efficient than older ones, explaining why fridges older than fifteen years typically consume excessive energy and cost a lot to run. 

Units that have been stuck in a warehouse for a long time may have been exposed to the elements or knocked around, making them potentially more faulty in the long run. 

To avoid that, ask for the manufacturing or delivery date. Then, if the unit has been on standby for too long, you can ask if there’s a new version of that model. If there’s none, choose a more recent model instead. 

Materials and Refrigerant Type

It’s also a good idea to look into the materials and components that make up the fridge. 

For instance, you should inquire if it is made of recyclable materials. When you need to dispose of your fridge after its natural lifespan, it’s better to have it recycled. 

You can take your old mini fridge to a dealer and see if they can recycle it. If not, you can take it to a facility compliant with EPA or Environment Canada

As for the refrigerant, we recommend models that still use CFCs and HCFCs. Models that use R-600a and R-441A are much more environmentally friendly because they contribute less to global warming than CFCs and HCFCs if they happen to leak into the environment.

Not all brands are upfront with the kind of refrigerant they use, making it important to consider only a reputable brand. 

Energy-Efficient Mini Fridge Pros and Cons

With their innovative and energy-efficient technology, modern mini fridges can be more expensive upfront than other models. This price might make you wonder if a more extensive and less state-of-the-art model might be more suitable. 

Let’s look at the benefits and downsides of buying an energy-efficient mini fridge.


  • Ideal for small spaces – mini fridges are great for those who live in limited living spaces, like tiny apartments or dorm rooms. 
  • Energy and cost savings – compared to a full-sized fridge, most mini fridges use less energy. Further, the energy savings are even more optimized if you opt for an energy-efficient model. 
  • Positive environmental impact – the less energy used, the better for the environment. The effect is even better if you recycle or choose a unit with eco-friendly refrigerant.  
  • Portability – because of their diminutive size, mini fridges are easier to transport or move than larger refrigerators. So if you need to move furniture and appliances around or move to another place, they are more convenient. 
  • Affordability – mini fridges are often cheaper than larger refrigerators, which is good news for students and other people on a low budget. 


  • No freezer – mini fridges don’t typically come with a freezer, so you can’t store frozen goods in them.

  • Limited space – the amount of items you can store in a mini fridge is limited because of the size. As a result, you may need to go to the grocery more often as you can’t stock up on too many items. 
  • Limited temperature range – most mini fridges cannot be as cold as full-sized fridges or stay cool for as long. So, while you can store some items in it, they can’t be there for too long, or else you risk food spoilage.  

It is important to note that many fridge companies have considered the cons and designed their latest models to address them. For instance, the models we’ll recommend later on all have freezers to allow the storage of perishable goods. 

Many mini fridges also allow the removal of racks and dividers to maximize the space according to your needs. So if you have bulky items, you can remove the partitions to fit them into the area.

  • Width: 20 inches (50.8 centimeters)

It also has an adjustable thermostat so you can set your fridge’s temperature between 32 and 35.6°F (-2° C to 2°C). This temperature range allows the model to reach lower temperatures than Upstreman’s FR17, but the range is narrower, so you can’t adjust it much.

Although it appears to have less capacity than the Black+Decker model, you can choose another unit with a bigger capacity. Options range from 2.5 (0.071) to 4.6 cubic feet (0.13 cubic meters), and the other dimensions will change with increasing space.
