There’s nothing better for a baby than the mother’s natural milk. But when you’re a busy working mom, it can be difficult to find a breast milk storage solution that will allow you to express and transport breast milk while keeping it fresh between work and home.

The best mini fridge for storing breast milk must have enough storage space for breast milk baby bottles, be able to be relied on to keep breast milk stored fresh and it must also be easy to clean and have a generous warranty. Click here to see the best milk mini fridge of 2021.

Breast milk cooler bags are great, but they won’t be able to reduce the temperature of the milk enough to preserve its lifespan, and putting breast milk bottles in the shared fridge at work could lead to your milk becoming contaminated or upsetting your coworkers.

This is where a mini milk fridge can come in handy; they are small, portable, and efficient. A breast milk mini fridge will allow you to cool, refrigerate and store breast milk in your office, car or while traveling, so it’s always fresh and available for your baby whenever hunger strikes.

Mini fridges sometimes get a bad rap for storing breast milk, but there is no reason why you can’t use a portable mini fridge to store and transport breast milk from one place (like where you work) to your home and into more permanent, long term storage.

Buying Guide: How to Choose the Best Mini Fridge for Breast Milk Storage 

When shopping for the best mini fridge to store breast milk and baby bottles, 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:

Temperature

The ability to adjust the temperature of your breast milk mini fridge is a helpful feature that will allow you to choose how cold your milk gets. For safely storing breast milk, you need the fridge to maintain the 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.

Likewise, the ability to store frozen breast milk may be handy if you are planning on storing your milk for later use or donating milk to another family. So having that adjustable temperature control feature may be helpful for you. Either way, it’s a good idea to always warm expressed breast milk before giving it to your baby.

Size and Capacity

For breast milk storage, you would want the capacity should be at least 4 liters; which is enough to fit about 3 or 4 17-ounce baby bottles.

Another factor to consider is if you want to store your pump parts in the mini fridge alongside your expressed breast milk. Keeping your breast pump parts in the fridge means you won’t have to sterilize them with each use. But of course, you will need to factor that extra size into your choice.

Generally speaking, the best mini fridges for storing breast milk 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, which makes it easy for transporting breast milk 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 breast milk storage.

On the other side, tall mini-fridges have more breast milk storage room but they take up much more space. If you plan to express breast milk at work and have your 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 traveling, 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 milk fridges with a good quality cooler bag to transport your cooled expressed 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.

Portability

Good portability means that you’re able to easily carry and move your breast milk 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 working breastfeeding moms. A small portable mini fridge is a great option for storing and transporting breast milk between work and home.

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. 

Additionally, some mini fridges have the ability to run on your car’s cigarette lighter, which will mean that if you are moving around in a vehicle often you will be able to keep your expressed breast milk stored at the perfect temperature. This is a super handy feature to have if you need that extra convenience.

Storage Time

The duration of the storage period can be short or long depending on the capability of the breast milk fridge, 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 milk storage options. For longer term milk storage, opt for a mini fridge with a compressor. 

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 portable mini fridge to keep stored breast milk cold while you are on the go, then you will need to be aware of the energy consumption levels of your target product.

For travel or in-car storage of breast milk, you will likely need a mini fridge with lower energy consumption and various power support options such as USB ports and cigarette lighters in vehicles.
