How to Choose the Best Mini Fridge for Breast Milk

When shopping for the best mini-fridge to store breast milk, there are some key features that you need to consider before making a purchase to ensure you end up with the right product. Here are the most important ones to keep in mind:

Size and Capacity

Generally speaking, mini-fridges are either cube-shaped or tall. Cube-shaped models offer more compactness so the chances of fitting them under a desk or on top of a counter are significantly higher.

Cube-shaped models are also more portable so they’re easier to carry from one place to another. They do offer fewer racks and less space, but they can be more than enough if you’re just looking for short-term storage.

For such models, the capacity should be at least 4 liters; enough to fit about 3 or 4 17-ounce baby bottles.

On the other side, tall mini-fridges are more storage room but they take up much more space. If you plan to pump at work, and have you own office space, it might be a good idea to buy one of the larger models, such as the Danby or the Midea. But if you are travelling, or otherwise moving around a lot and don’t have your own storage space, a more compact model like the Cooluli will be a better option, because it takes up a lot less space and can be powered with your car’s cigarette lighter.

Remember that you can match these mini fridges with a good quality cooler bag to transport your breast milk from work to home, or while you are out and about. I’ve got a great article on cooler bags for breast milk here.


For safely storing breast milk, you need a temperature of around 39°F (4°C). So it’s important to make sure that the fridge you buy can maintain this as an average temperature in all its compartments.


Good portability means that you’re able to easily carry and move the mini-fridge from one place to another while still getting the best possible cooling capacity whether indoors or outdoors.

Portability makes life so much simpler for breastfeeding moms, especially those who pump at work. This is why you should take the size of the mini-fridge into account, as well as look for models with lightweight construction and convenient carrying handles if you will be moving the fridge regularly.

Storage Time

The duration of the storage period can be short or long depending on the capability of the model, the frequency of use, and how long it takes the mom to restore the fresh breast milk.

If you are busy or planning for longer trips, you may prefer a more long-term storage duration models. These will feature a compressor-based operation.

On the other hand, moms who prefer giving their babies breast milk as fresh as possible can be better off with short-term storage options. These are equipped with thermoelectric semiconductors.

Energy Consumption

If you’re in the market for an efficient mini-fridge to take on the go, then you should be checking the energy consumption levels of your target product.

You want a mini-fridge with lower energy consumption and various power support options such as USB ports and cigarette lighters in vehicles.

Tips for Storing Breast Milk in a Mini Fridge

  • Avoid using glass bottles to store breast milk in a mini-fridge since there’s a risk of breakage. Instead, use sterilized containers, plastic breast milk bags, or hard BPA-free plastic bottles.
  • Make sure everything is clean when handling and storing breast milk to prevent bacterial growth.
  • Always label the breast milk bags or bottles and clearly state the date. Use the older ones first.
  • Heat breast milk by using a bottle warmer, or by placing the bottle in a bowl of lukewarm water to bring it up to body temperature. Do not use a microwave to warm chilled or frozen breast milk.
