4 Best Portable Bottle Warmers – Reviews

If you go to your web browser and start looking for the best travel bottle warmer for breast milk, formula, or regular milk, you’ll realize that there are so many options. I might say even too many. For that reason, I have compiled a list of the best travel bottle warmers.

As you will see, I will include all the relevant features, pros, and cons, so you’ll have everything you need to choose the right bottle for you and your needs. At the end of the list, I’ll present the winner (in my opinion). In case you can’t make up your mind, this suggestion can help you out.

1. The Baby’s Brew Portable Bottle Warmer

The Baby’s Brew was invented as the first portable baby bottle warmer battery-operated. That made this bottle warmer unique in 2019, as it was the only baby bottle warmer with battery as the power source.

Baby Brew portable bottle warmer battery operated

It allows you to warm your breast milk to 4 different temperatures, including 98.6°F which is the safe and familiar for breastfed baby temperature, as I’ve mentioned earlier.

It can be used for both formula and breast milk. Baby Brew bottle warmer is perfect for breast milk bottles as you won’t need to deal with unnecessary formula dispenser. In case you do need a formula dispenser, opt for their Baby Brew Portable Bottle Warmer Pro Set.

How does The Baby’s Brew work?

The Baby’s Brew works on rechargeable battery (charger included in the set). For me it turned out to be so much better than I expected – so easy and convenient to use.

To use The Baby’s Brew warmer:

  • First remove the silicone cover that protects it from dust.
  • Check if the silicone ring is in place, around the warming plate.
  • Flip the warmer and attach it to your baby bottle by carefully screwing it on top of it.
  • Flip it over again – the liquid is now touching the warming plate.
  • Press the button on the bottom of the warmer to select the temperature.

That’s it! Easy-peasy!

What distinguishes Baby’s Brew among portable bottle warmers is that you can actually set your preferred temperature. There are 4 temperature settings: 80°F (room temperature), 98.6°F (your body’s temperature, ideal for breastfeeding babies), 104°F (for other liquids) and 113°F.

That wide range of settings was designed to meet different feeding needs, whether your baby is on breastmilk or formula.

The highest setting I would recommend for preparing the bottle BEFORE your baby gets actually hungry, for example if you know that you won’t be able to use the warmer exactly when your little one needs the bottle. Warm it and just leave it to cold down a bit. The brand also recommends this setting for acid reflux.

Before you serve the milk, always check its temperature on the inside of your wrist.

The lower temperature settings – 80°F and 98.6°F allow to preserve the essential nutrients from your body and protect them from damages that heat could cause. These settings makes The Baby’s Brew the best travel bottle warmer for breastmilk.

Baby Brew can be purchased with or without the formula dispenser
On the left side you can see the standard package that includes just the bottle warmer and charger, on the right side you can see the Pro Set that includes also a formula dispenser

One more noteworthy thing is that Baby’s Brew brand also offers a formula dispenser, included in the Pro Set (check it out here). It’s costs only $10 more than the warmer itself! If you’ll be using this travel bottle warmer for formula, I think it’s a good investment.

The formula dispenser is also very easy to use. One push equals one scoop of formula.

What baby bottles are compatible with The Baby’s Brew warmer?

What’s important, you can use this portable bottle warmer with all the most popular wide-neck baby bottles. If your bottles has a different neck – don’t worry! The brand offer lots of adapters, each costs $9.99.

Best Travel Baby Bottle Warmer – Buying Guide

Before you take your credit card and purchase your new favorite portable bottle warmer – here are a few important things you should keep in mind.

Portable Bottle Warmers vs. Standard Bottle Warmers

The main difference between standard bottle warmers and portable bottle warmers is the need for electricity. For standard bottle warmers, you need an electrical outlet. That’s why they are impractical for travel.

Besides traveling, portable baby bottle warmers are useful when you’re running errands, relaxing in the park, commuting, or whenever you are outdoors with your little one. They are especially handy when you want to serve your baby the breastmilk from your fridge stash.

Busy parents will fall in love with this accessory.

When You Might Need A Portable Bottle Warmer

If are still thinking about whether you really need a portable baby bottle warmer, here are some situations when it comes in handy:

  • Traveling by plane – You can take some of the portable bottle warmers on a plane. Among the warmers on my list, The Baby’s Brew bottle warmer is safe to be used on a plane.
  • Going to a restaurant – Forget about asking the waiter to bring you hot water and all that commotion.
  • Running errands
  • Road trips
  • Spending time in nature
  • Day trips to Disneyland or the zoo

Types Of Portable Bottle Warmers

If you want to warm a baby bottle without being dependent on the charging outlet you should opt for travel bottle warmer.

Depending on how it operates, there are 4 main types of portable warmers for baby bottles:

  1. Battery-operated – I think they are most handy and reliable.
  2. USB – They are charged via USB cable.
  3. In-car bottle warmers – They can be plugged into your car’s cigarette lighter or power socket.
  4. Flask baby bottle warmer – This is the thermal bottle for hot water that works as a regular thermos, but includes additional lid where you place the bottle.
Flask-type warmers have probably more disadvantages than other types. You should never put the milk in a boiling or hot water, so before you place your bottle in the warming lid, make sure the water is warm, but not super hot! If the water is too hot it will destroy nutritional value of the breastmilk. Besides, it may break the bottle (not all plastic bottles are suitable to be put in hot water). You should always use warm water.

Features To Look Out For

Now, the big question: What features should the best portable bottle warmer have?

Of course it will highly depend on your needs. For example, if you often run errands with your baby and you need the milk to be ready fast, don’t go for a bottle warmer that takes up to 30 minutes to warm the milk.

Or, if you are traveling by plane or a car, and there aren’t many stops, you might want to consider using bottle warmers that don’t require water. Otherwise, the turbulence or the bumpy road can create a scenario where the water ends up all over you and burns you.

Besides, if you’re traveling only with the carry-on, you won’t be able to bring the bottle of hot water on board with you. In that case battery-operated travel bottle warmer, like The Baby’s Brew, is better choice.

If you’re searching for best travel baby bottle warmer, consider the following:

  • When will you use it the most?
  • Is it safe for both: the breastmilk and formula?
  • How long do you need it to last on one charge (or how long does it keep the water hot)?
  • What temperatures you want to reach? – Higher temperature demands more time so you’ll need a more powerful warmer
  • Would you like to be able to choose your preferred temperature?
  • How easily and quickly does it work?
  • Is it compatibility with the feeding bottles that you use?
  • Is it portable?
  • Can you bring it on a plane?
  • How compact is it and how much space does it take in a diaper bag?
  • Would you like to use it for warming up baby’s food as well?

Advantages Of Portable Bottle Warmers

Being a travel-loving parent isn’t easy. That’s why I’m so fond of portable bottle warmers. It helps to merge parent role with passionate traveler role. These are some of the advantages of portable bottle warmers that I’d like to point out:

  • You can warm the bottle when you are traveling.
  • They are perfect for parents who are often on-the-go with their baby.
  • You don’t have to bother anyone (waiter, hosts, etc.) to warm up the milk.
  • Milk reaches the desired temperature in a few minutes – it’s usually slower than with a regular electric bottle warmer, on the other hand it doesn’t create hot spots in the milk that could burn baby’s mouth.
  • You can feed your little one whenever you want – no more “wait till we get home sweetie”.

How Do You Warm Bottles When Traveling?

The best way to warm bottles when traveling is to use a portable bottle warmer, whether it is a rechargeable battery-operated bottle warmer, in-car bottle warmer, thermal bottle for hot water or USB-type warmer.

I would say that if you’re on the go, on a day trip or travel by plane – the most handy and convenient solution is battery-operated bottle warmer. Keep in mind it may not be possible to use thermal bottle with hot water on a plane!

If you’re on a road trip – you may want to use in-car bottle warmer or the battery-operated one.

If you’re outdoor exploring nature, sightseeing or hiking – the easiest way to warm the milk will be to use warm water (thermos-type bottle warmer) or a warmer that works on batteries.

Tommee Tippee is one of the best travel bottle warmers not only for baby's milk but also food

How Do You Warm A Baby Bottle Without Electricity?

Using a portable bottle warmer is one option to warm baby’s bottle without electricity. It’s important to choose the right one – if you don’t have access to electricity or just look for a more affordable way to warm the bottle, it’s best to choose a flask-type bottle warmer.

If you’re at home and want to warm a baby bottle without electricity, just hold it under running warm tap water, or put it in a pot / bowl full of warm water. It’s the easiest way. Keep in mind that your baby doesn’t need hot milk, the best is the body temperature. Besides, you should never put milk in hot or boiling water because it will destroy its nutrients. Moreover, some plastic bottle may melt in very hot water!

Final Thoughts
