Best Mini Fridge for Breast Milk (With and Without Freezer)

Baby drinking bottle

For many breastfeeding mothers, a mini fridge is the answer to breast milk storage woes. Being the curious father that I am, I decided to check out the different models on the market. The BLACK+DECKER BCRK17B Compact Refrigerator was my best mini fridge for breast milk, but you’ll find many other options on this list to consider too.

Storing expressed breast milk correctly is essential for your baby’s wellbeing. It needs to be kept cool if being consumed on the same day or frozen if you’re storing it for future use. Being able to store breast milk safely while keeping it fresh, gives mom the opportunity to hand over the feeding of the baby to the father or a caregiver. And I’ve had a lot of such days as a father when I was the sole caretaker of our daughter.

My Top Picks

Buying a Mini Fridge for Breast Milk

When you’re done expressing your breast milk with a breast pump such as Willow, Elvie or Freemie wearable pump, it needs to be kept cool. And, this is where a mini fridge can be useful. It gives you the flexibility of keeping your breast milk on hand – whether in your office, bedroom, or your baby’s nursery. Instead of popping down to the kitchen all the time, keeping your mini fridge close-by makes your life a whole lot easier.

Whenever parents are in the market for a baby product, it’s always a good idea to do some research. Use my buying guide to save you the hassles of spending hours on the Internet. My article includes five different mini fridges with features ranging from freezers to portability.

Freezing vs Refrigerating your Breast Milk – Differences

If you’re wondering whether you should be freezing or simply refrigerating your breast milk, it’s important to know the difference. While freshly expressed breast milk can be kept at room temperature for up to 4 hours, it’s advisable to use a cooler if you want to keep the milk stored for a day – like while you’re at work or while you’re little one is at daycare. Breast milk can be kept at the back of a refrigerator for up to 5 days while frozen milk can be kept in a freezer for up to 12 months!

It’s also important to know that the longer expressed breast milk is kept frozen, the higher the loss of Vitamin C in the milk. And newborn baby’s breast milk is different to an older baby’s breast milk so keep this in mind when choosing to store breast milk for long periods of time. It’s useful to know the ideal temperature for refrigerating breast milk is 4C or lower. A freezer should be below -18C. This will give you peace of mind that your milk is still safe for your baby to consume 6 months down the line. Breast milk cooled in the refrigerator can be carried in a cooler for up to 24 hours.

Where to place a mini fridge

Wondering where you can set up your device? There are a few places you might want to consider: in your kitchen, in your own bedroom or the mini fridge could go in the nursery. The latter might be the best solution for many, since anyway most of the baby stuff are stored there. You can read about other benfits (and concerns) in the article I wrote..

What to Look for in a Mini Fridge

It’s always a good idea to know exactly what you want to achieve from your mini fridge. Whether it’s for keeping your breast milk cool for a few days or to be frozen for future use, these features to look out for will help you make your final decision:

  • Dimensions: Despite being “mini”, these small fridges do come in a range of sizes. If you’re looking to keep your mini fridge in one place, it’s good to measure the space before purchasing. The BLACK+DECKER, Midea Reversible Refrigerator and New Air Beverage Cooler and Refrigerator are of similar sizes. Both the AstroAI and Cooluli models are way smaller comparably but note they are coolers and meant for portability.
  • Cooling and freezing options: Mini fridges offer different cooling options. Some operate purely for keeping items cool such as the AstroAI and Cooluli Mini Fridges (and they are warmers). The New Air Beverage Cooler and Refrigerator does not have a freezer while both the BLACK+DECKER and Midea Reversible Refrigerator do.
  • Thermostat control: It’s important to check the temperature control to determine the temperature range of your mini fridge. Both the BLACK+DECKER Compact Refrigerator and the Midea Reversible Refrigerator have adjustable temperature controls with a decent range in temperatures. The New Air Beverage Cooler and Refrigerator has a thermostat control with 5 settings but it’s placed at the back of the fridge which makes access difficult. The AstroAI and Cooluli Mini Fridges are coolers and warmers. They have limited thermostat settings but can convert from cool to warm temperatures by selecting the option.
  • Functionality: This is very important if you’re traveling with the mini fridge. Both the AstroAl and Cooluli Mini Fridges have AC/DC adapters which means they can be plugged into the standard wall socket and the cigarette lighter socket in your car. The BLACK+DECKER Compact Refrigerator, New Air Beverage Cooler and Refrigerator and Midea Reversible Refrigerator are plugged into standard wall sockets.
  • Storage space: Depending on how much storage space you need, you want to check out the interior of the mini fridge to see that it’s not cluttered with equipment or bulky sides. The storage space of the freezer compartment is also an important consideration. As expected, the AstroAI and Cooluli Mini Fridges are not big on storage space. The New Air Beverage Cooler and Refrigerator boasts the largest storage capacity although there are no shelves in the door. Both the BLACK+DECKER Compact and Midea Reversible Refrigerators have good storage capacity with additional shelving in the doors.
  • Pricing: Purchasing a mini fridge can be an expensive outlay. If you’re sticking to a strict budget, AstroAI and Cooluli Mini Fridges are the cheaper options. The BLACK+DECKER Compact Refrigerator is the most expensive while Midea Reversible and New Air Beverage Refrigerators are comparably similar in prices.

What are the best containers for storing expressed breast milk?

Sterilized clean bottles with screw caps work well. You can use plastic cups with tight lids but make sure the plastic is of high-grade quality. Pre-sterilized nursing bags designed to hold breast milk can be used.

How do I thaw frozen milk?

Remove the container from the freezer and hold it under warm running water. Otherwise, take it out the day before – it takes 24 hours for frozen milk to thaw completely. Never refreeze the milk.

What quantities should I store my milk in the freezer?

It’s best to store milk in 2 to 4 oz portions so you don’t waste any. A clever way to store milk is in ice trays. Once frozen, store the cubes in freezer bags. Remember to clearly label the containers with the date.

What’s the maximum room temperature for storing breast milk outside of a fridge?

Your room temperature should be no more than 25 degrees Celsius. Do not leave the milk out for more than 6 hours. Watch this educational video to find out more about how to store breast milk.


With so many mini-fridges being available on the market, it is a tough choice to find the best mini fridge for breast milk. In the end, I used my list of features to help me find the most suitable one for storing breast milk. Without a doubt, the BLACK+DECKER Compact Mini Fridge with Freezer did it for me.
