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.

Very slow to heat up, runs out of power quickly

Warms Breast Milk or Formula very fast.
Works great and is fast but it should not say baby bottle warmer, it only heats the breast milk or formula you pour into it, then you pour it into the bottles. Easy to charge and clean.

Preferred warmer
We love this thing! It’s a top loved item in our house and we haven’t used it for travel yet. Not a fan of placing a plastic bottle in a warmer so this is the way to go for us. It’s quick to warm, easy to clean and operate. I do sometimes measure the milk in a bottle before instead of trying to use the measure lines inside the warmer but that no big deal. The battery life is pretty good and recharging is never a problem.
