11 Questions
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.

Can a bottle of milk be inserted or does the milk need to be poured in separately? ?

Best Answer:  The milk needs to be poured in separately, but they also offer this product that can be used with a bottle.

How to clean?

Best Answer:  To clean the Momcozy Portable Breast Milk & Water Warmer, unplug and cool it, wipe the heating plate with a damp cloth, wash removable parts with soapy water, and descale with vinegar if needed, avoiding immersion of the base.

Loved this! I was exclusively pumping for a couple of months and truly couldn’t have done it without this on the go.

Lid
I am trying to find a way to get a replacement lid and can’t seem to find one. Any ideas

Disappointed
I’m unfortunately very disappointed with this bottle warmer.

First, it doesn’t heat consistently. Often it shows 70 or even 80 degrees, but the formula/milk is still completely cold. That makes it very unreliable, especially when you need to prepare a bottle quickly.

Second, it leaks easily. If I place it on the bed and it tips over, the liquid spills out. It really should have a proper sealing system like a normal bottle to prevent this.
Finally, the device turns off

Don't buy this!
This is the worst bottle warmers I've ever had. Truly no way of keeping it sanitized unlike the Papblic. The lid is also so flimsy and broke within the second use. Absolutely regret asking for this on my registry. You're better off with a different one or just sticking the bottle in a hot cup - much more sanitary than this mold inviting nightmare of a bottle warmer.

No for me
I have been using this for four months and there is rust in the bottom. I tried to submit a warranty but waited online for 2 hours and then they wouldn’t give me one because I received it as a gift from my shower.

Also, it takes forever to warm.

Práctico y rápido
Compré esto y el termo enfriador/congelador. Ambos son excelentes. El calentador te da para calentar muchas tomas, 4 o 5 tranquilamente (aunque si la leche esta muy fría o calientas agua a una temperatura más elevada de 37ºC quizá no puedas calentar tantas tomas). Lo único que me gustaría sería poder meterlo en el esterilizador pero con un buen lavado y secado ha sido suficiente en nuestro caso. Además al cabo de un tiempo apareció oxido y pudimos cambiarlo por otro. El servicio postventa es excelente.

Tolle Verarbeitung und ein absoluter Gamechanger. Ich bin absolut begeistert vom Produkt. Dadurch sind wir als Familie aber auch mein Freund, wenn er alleine mit der Kleinen ist, total mobil.

Die Handhabung ist einfach, die Milch schnell auf der richtigen Temperatur und die Reinigung geht schnell.

Great product and even better customer service
I ordered the Momcozy portable bottle warmer and was really looking forward to trying it. Unfortunately, UPS marked my first package as delivered even though nothing ever arrived. I reached out to Momcozy, explained the situation, and once I confirmed at the end of the day that the package still hadn’t shown up, they immediately sent out a replacement with no hassle at all.

The new one arrived quickly, and the product works exactly as expected, super convenient and perfect for on‑the‑go
