Portable Baby Bottle Warmer: Do You Need It + Best Models

How do you warm baby bottles when traveling or spending days outside? is the most popular question from new moms. When my firstborn came around, from day 3 we were never at home and we started traveling abroad with him when he was 2 weeks old. I simply brought a bottle of still water and a bottle of hot water in a thermos so I could make formula on the go.

This solution worked fine. We survived and for a long time I didn’t think one can do it a different way, but I had to stick my finger in the water to make sure it was not too hot or too cold. Thankfully, now thanks to portable bottle warmers you don’t have to risk burning your fingers.

Do you absolutely need a bottle warmer?

Not at all. A bottle warmer is a gadget and you can still feed your baby on the go. In fact, when we were limited on luggage I was still warming up my baby’s food and milk in a cup of hot water at the hotel and it is one of my tips for traveling with a baby. However, it’s a useful gadget that can often make your life easier so now it’s part of my personal essential baby travel gear list.

Can you bring a baby bottle warmer on a plane?

You can, but of course keep in mind that not all airlines have chargers in seats, so they might not work.

One thing to note is taking a powerless version means you need to go through extra screening at security or find boiling water after security and before you get on the plane, but ultimately it’s a safer option than finding out that the seat has no chargers.

Can you use a portable bottle warmer for breast milk?

Depends on the model, but generally speaking yes for some! Most bottle warmers will heat the milk to 98 degrees which most closely mimics a regular body temperature and breastmilk.

Best Portable Bottle Warmers for Travel

This portable bottle warmer doesn’t require any electricity as it is essentially a high-quality thermos in which to store 500ml of hot water for warming your baby bottles. 

What makes this different from using a regular thermos however is that it comes with an extra cylindrical container that fits snuggly over the thermos for easy storage

Best Traditional: Tommee Tippee Easiwarm Bottle Warmer (formula & breastmilk)

This bottle warmer is much like a regular bottle warmer you would use at home but it’s also compact and easy to travel with. 

It uses steam to heat baby bottles in just 4 minutes and has two settings for warming from the fridge or room temperature. It also allows you to set it to keep warm so you don’t have to reheat it if your baby isn’t quite ready to feed yet.

  • Two different temperature settings
  • Faster than boiling water
  • Keeps warm function means it won’t turn off when it reaches desired temperature


  • Needs a power outlet to work
  • Doesn’t turn off by itself
  • No power stitch (have to unplug it from the wall to turn it off)

Best Warmer and Sterilizer: Dr. Brown’s Insta-Feed Baby Bottle Warmer and Sterilizer (formula & breastmilk)

This compact baby bottle warmer not only warms both formula and breastmilk but also sterilizes. Having a sterilizer can be very convenient when you are traveling as you never know when you will drop a bottle when out and about. 

Dr. Brown’s Insta-Feed Bottle Warmer fits most branded bottles and includes a measuring cup and adapter rings to ensure your bottle is secured. It also has a lift-out basket so you don’t have to burn your fingers retrieving any small items you need to clean. 

Another thing that makes this bottle warmer stand out is its speed. It claims to be able to warm a bottle in just 90 seconds. While that may be pushing it a little bit, even 2 mins is better than the previous bottle warmers on this list. 


  • Very quick (down to 90 seconds to warm)
  • Includes a sterilizer
  • Fits many different bottles


  • Can sometimes get too hot
  • Needs a power outlet to work
  • No temperature control buttons – a few steps are involved to figure out the amount of water needed for the correct temperature

Best for Formula: Bololo Portable (formula only)

This battery-powered bottle warmer is a great option if you want to make formula on the go as you only require a power outlet to charge it every 7 feeds or so. Even then, it only takes 1-2 hours to fully charge. 

Bololo Portable heats water in around 5 mins and has a temperature display on the outside so you can get a precise temperature without having to guess.

The inside is also made from stainless steel rather than plastic so you won’t have any problems cleaning but some people have said that the plastic lid still gives off chemical smells in the beginning. 


  • Battery-powered and fast charging 
  • Temperature display shows degrees of contents
  • Can warm around 7 times on a single charge


  • Not for breastmilk
  • Only holds 10oz
  • Quite heavy

Most Multifunctional: Grownsy 8-in-1 Fast Milk Warmer with Timer (formula, breastmilk & food)

If you’re looking for one machine that will do it all and you’re not worried about space or weight, this is a great choice. 

The Grownsy 8-in-1 has so many functions and settings that you can really get precise with what you want to warm and to what temperature. 

Taking around 5-6 minutes to warm a bottle, it sits in the middle of the range when it comes to speed but the size is undoubtedly a lot bigger than the others on this list. 


  • Has serializer 
  • Precise temperature controls 
  • Can warm two things at once


  • Very bulky
  • Pricey
  • Too many settings can be a little confusing
