Q&A
Have a question? Ask an expert.
Start typing and see existing answers.
What is the voltage? Can I plug it in overseas at 220 or 240 volts?
Best Answer: The Momcozy Portable Water & Milk Warmer (MW05) does not plug directly into a standard AC outlet. It charges via USB-C and accepts a USB-C power input of 5V⎓3A or 9V⎓2A.
Does this work on premixed powder formula that’s been in the fridge or my mom cozy cooler?
Best Answer: Yes. The Momcozy Portable Water & Milk Warmer is designed to warm both breast milk and prepared formula, so you can use it to warm pre-mixed powdered formula that has been stored in the refrigerator or kept cold in a Momcozy cooler.
How do I know when the breastmilk is warm and ready to be transferred to the bottle? ?
Best Answer: The Momcozy Portable Water & Milk Warmer has a digital temperature display, so you’ll know it’s ready when it reaches your selected temperature (many parents choose around 98°F/37°C for breastmilk). Always swirl gently and test a few drops on your wrist before feeding to make sure it feels lukewarm, not hot.
Does it keep milk cool inside until time to heat?
Best Answer: No, the Momcozy Portable Water & Milk Warmer is designed to heat and keep liquids warm—it does not have a cooling or refrigeration function. You’ll need to keep milk chilled separately (like in a cooler with ice packs) until you’re ready to warm it.
Can you use glass bottles?
Best Answer: You warm the milk directly in the momcozy Portable Water & Milk Warmer. Once heated, you can pour the warmed liquid into any bottle using the built-in spout.
Stainless steel inside the bottle? ?
Best Answer: The interior of the Momcozy Portable Water & Milk Warmer features a stainless steel chamber.
Can this be used to warm ready to feed formula?
Best Answer: Yes, the Momcozy Portable Breast Milk & Water Warmer can be used to warm ready-to-feed formula. It features dual heating modes for warming both breast milk and water, allowing you to pour the formula directly into the warmer’s internal chamber.
Can this be taken on an airplane?
Best Answer: Yes, you can bring the Momcozy Portable Breast Milk & Water Warmer on an airplane.
Can you use this for formula?
Best Answer: Yes, it warms 4 oz water in 2 minutes for mixing formula.
How long does this keep liquids cold for?
Best Answer: The Momcozy Portable Breast Milk & Water Warmer is primarily designed to heat liquids rather than maintain them at a cold temperature. If you're looking to keep breast milk cold during travel or outings, Momcozy offers a separate product specifically for this purpose: the Momcozy Portable Breast Milk Cooler. We offer this in our shop at the link below. This Breast Milk Cooler features 360°-surround cooling tube technology that keeps temperatures consistently cold for over 24 hours.

Love it, but the latch.
This is great for traveling and making sure milk is warmed. It has saved me alot of troubles. However, the latch on the lid keeps breaking and can't find a way to replace lid. It breaks after about 6 to 7 months. So buyers be aware to treat the lid very carefully.

Best Investment for a Busy Mom
Purchased as I have two older children who are very active in sports and needed a way to warm breast milk on the go! This warms it to a perfect temperature and I never have to miss any of the action! A staple in our ballpark gear! Has also given us the freedom to plan longer outings without worrying about having hot water available or trying to feed baby cold milk! 10/10 absolutely recommend!

A must have for parents on the Go!
I absolutely love this bottle warmer! I wish I had found it sooner. It heats water quickly, making it so easy to prepare my babys bottles whether were at home, in the car, or out running errands. I keep it packed with my formula dispenser, so I can make a warm bottle anytime my baby is hungry. Its lightweight, portable, and has made feeding on the go so much easier. Definitely one of my favorite baby purchases!

Good Bottle Warmer
This is a really good warmer that heats our babys milk quickly, about 3 minutes to get to 97 degrees from room temperature and will keep milk warm until you turn off and ready to serve. This bottle is aesthetically very nice and love the purple color. The only downside is how heavy it is

Works well with some flaws
Warms breast milk gently to max 98 degrees (body temp) but if your LO likes their milk warmer than that, youll have to get a sleeve bottle warmer like we did. This warmer doesnt fit into our cars cup holder well so that was annoying but otherwise the warmer works well. The silicone ring that fits inside the lid (to seal the lid) comes out too easily, so theres high chance of it falling into the milk (which has happened many times) or losing the ring itself. So far its been dependable on trips and outings.
