Nursing Moms Review Best Mini Fridge for Breast Milk

Last Updated on May 30, 2022 by

With the best mini fridge for breast milk, you would find it convenient to store pumped breast milk for your baby. You would not have to go downstairs to get the baby items during late-night feedings, and HRs are okay with a mini fridge.

A mini fridge for breast milk should be compact with at least a 4-liter capacity. Should be able to cool up to 32-40℉ (18-22℃) or keep warm up to 150°F (66°C) within 2 hours. It is also important to buy a freon-free and environmentally friendly mini fridge with multiple power modes.

Investing in a mini fridge is seriously the best thing ever. It helps to store the breast milk for nighttime when you are pumping and bottle feeding. When you no longer need it, you can convert it to a cosmetics fridge.

Can you store breast milk in a mini fridge?

You can store breast milk in a mini fridge. Moreover, you can store freshly pumped or expressed milk in the fridge for up to 4 days. In the freezer, breast milk will last for about 6 months at best, and up to 12 months.

Consider getting a mini fridge for breast milk if you have the space under your desk in the office. You could even store water and snacks, in addition to breast milk in it.

This way, if you forget to take your milk cooler home, you do not lose the entire day of pumped milk and can just take it the following day.

The cost of a mini-fridge is about $100 for a small 1.1 cubic model. You would also find them on sale around mid-summer, just before the start of college.

Inform your HR about getting a mini fridge. Most companies are okay with mothers getting one as long as you use it for storing breastmilk.

Are mini fridges cold enough for milk?

Mini fridges are cold enough for milk. Besides, you can place breast milk in the refrigerator at 39°F or 4°C. A mini fridge can cool down to 32 degrees Fahrenheit, making it cold enough for storing your breast milk.

If yours has a 4-liter capacity, that should be more than enough for a few prepped breast milk bottles. A mini fridge is quick with an average cooling time of about 4 hours.

Speaking of convenience, a mini fridge will fit practically anywhere. It sits nicely in the corner or countertop.

It runs quietly at 25dB, which is thrice quieter than a normal human conversation.

Easy fan cleaning

We could easily clean the can. All we have to do is to remove the back cover screws and use a dry cloth for the fan.

Do not force out the back cover directly to avoid damaging the switch wire connected behind it.

What we don’t

Can size only

This mini fridge does not fit water bottles unless pony-sized. It would help if the top tray comes out to allow fitting in taller items.

No interior light

No illuminating interior light for night convenience.

No temperature adjustment

You cannot adjust the temperature. This fridge usually maintains a temperature in the upper 30s to low 40s when you switch it to the cooling position.

You can keep this mini refrigerator plugged in. If you plug it into your car, do not forget to disconnect it when you turn it off to avoid draining the car battery.

We stored breast milk cool to 35 to 38 degrees while the fridge is closed.

Cooling duration without electricity

Without electricity, this fridge remained cool for about 1.5 hours after. Note that the cooling time is affected by your environment.

What we don’t

4 cans only

Unless there is a bigger version of this, we could only store 4 cans, as opposed to the 10 cans advertised. Perhaps, the manufacturer meant those 6-ounce juice cans they sell.

This mini fridge will not fit 10 soda cans but 4. We tried storing the cans vertically and horizontally. We also lay the cans across or lie front to back but won’t fit even 5.

Are mini fridges worth it?

Mini fridges are worth it. Consider the following reasons:

Portable and compact

Its compact size for your breast milk makes it easy to carry about. You can have them in your dorm, RV, or anywhere in the office without space being a problem. This means your baby’s milk is always conditioned anywhere you go.

Energy efficient

Due to its small size, you can tell that it saves far more energy, compared to the tradition-sized fridges. A mini fridge for breast milk can even be powered in your car, so energy consumption is never a concern.

Besides, it would be impractical to turn on the large-sized refrigerator just to condition your breast milk. This takes lots of power until cools.


A mini fridge may look smaller on the outside, but the space is quite generous on the inside. Some mini fridges even have partitions and removable shelves for additional storage space. I.e., while the breast milk goes on one shelf, your fruits, coffee, and cosmetics go on the other.


A reliable mini fridge will cost between $70-$250. Remember, you do not need a mini fridge for just the breast milk—you would store cosmetics, fruits, and more to condition them at a cheaper price than you would be using a traditional refrigerator.
