The bottle warmers in this section don’t need to be plugged into an outlet to work. Some do require a power source, and those come with car adapters. These portable bottle warmers are good for flights, road trips, outings, etc.
It’s a three-part bottle warmer – you get the thermos bottle that keeps water hot all day and two Insulated warming cups. One warming cup is larger than the other, to accommodate the different sizes of bottles.
The way it works is you choose an insulated cup which is compatible with the bottle you want to warm up. Then you put the bottle in the cup and pour hot water from the thermos around it. Close it with the other cup, and you can just throw it in your diaper bag and be on your way.
The time this takes to warm up a bottle depends on how hot the water in the thermos is. Some people use just hot tap water, and that can take maybe 5-10 minutes. But if you actually boil water and then pour it in the thermos, it won’t take longer than 2-3 minutes to get the milk to a temperature that’s safe for your baby to drink.
The thermos works really well, and it will keep the water in it hot even after several hours. And the big warming cup is large enough to fit even the bulkier milk bottles, which is great.
Overall, this bottle warmer is small, functional, and affordable. It fits into your purse or carry-on and allows you to have warm milk pretty much anywhere in just a matter of minutes. But there is the issue of weight. The entire warmer weighs about 12 ounces, plus the 18 ounces of water that you’ll have to pour in the thermos. That’s almost 2 pounds, in addition to everything else in your diaper bag.
The Tommee Tippee bottle warmer is a typical portable bottle warmer that uses hot water to work. It includes an insulated thermos that you pour hot water into and a plastic cup that is used to actually warm up a bottle. The thermos is well made and it can keep water hot for hours. It is made from stainless steel, and it is very easy to clean.
The lid of the insulated bottle is leak-proof, so it is pretty safe to just throw it in your bag. Additionally, the manufacturer recommends that you pour boiled water in it, for the best results.
This works for warming up a bottle fairly quickly. Put the baby bottle in the plastic cup, pour some hot water into it and wait a couple of minutes. But it doesn’t really work for keeping a bottle warm – I don’t think that it would be safe to carry the plastic cup in your bag when there’s hot water inside it. Especially because it doesn’t have a lid. :>
The cap of the plastic cup is very wide, and it can fit all kinds of bottles. That’s great – you’re not restricted just to Tommee Tippee ones. Also, the thermos fits nicely into the white cup, which makes it very convenient to carry around. But there’s the issue of weight – this is just another thing you have to carry around, and when it’s full of hot water it does get kind of heavy.
So, this bottle warmer is something different. But it’s a good option for travel – it’s a diaper bag that can fit all of your necessities, and which comes with a portable bottle warmer. It is a USB bottle warmer, but people are actually saying good things about it! So, if you would like to try a USB bottle warmer, I highly recommend getting this diaper bag.
As a bag, it is stylish, spacious, and small enough that you can use it as a carry-on. It is made from Oxford fabric, so it is pretty durable and won’t tear easily. The bag is waterproof and has dedicated slip pockets for baby bottles. Those pockets are lined with tin foil, so they can keep a hot bottle warm throughout the day.
And then there’s the bottle warmer. You can plug it into the bag if you’ve charged it, or just into a power bank. You get a USB cable with the bag, but you don’t get a power bank.
The portable bottle warmer is very small, so it is very portable. And it actually works – it gets enough charge with the USB cable that it can warm up milk pretty well. Additionally, you can use the USB port on the bag to charge your phone, which is a very nice bonus.
If you are looking for a simple bottle warmer, then this might not be the best choice for you. It is pretty pricey to buy this bag just for the warmer. But, if you want something versatile and very functional, then definitely try out this bag.
If you need a portable bottle warmer that’s good for a road trip, I definitely recommend the Harmily. It is a great warmer that you can always keep in your car because it is really small and lightweight. This bottle heater is made from heat-insulating material that does a good job of preserving heat.
Also, the material is elastic and it can stretch to fit most water bottles. There is an opening zipper, which helps you fit some bulkier bottles.
The Harmily plugs into the car lighter and it can warm up a bottle of milk pretty fast. It has an insulation temperature of 65°C and a holding temperature of 35°C, which is pretty decent for such an affordable travel bottle warmer.
This bottle warmer also comes with a small carabiner, which is very useful when you’re in the car alone. You won’t be able to fit this into a cup holder, and the carabiner really helps there. Plus, it has automatic protection from overheating, which makes it a rather safe choice.
Overall, I think that this is a decent travel bottle warmer to have in your car. It is by no means a remarkable product, especially because its use is so limited. But it is made from heat-insulated material, which can preserve heat very well even when it is not plugged into a power source.
I have to throw in one of these bottle warmers. If you are looking for something that can keep a bottle of milk warm for hours, this is a go-to. The insulating material inside helps the heat circulate and preserves it for very long periods of time.
But it also works really well as a cooler. You can throw an ice pack and two bottles with frozen/refrigerated milk inside this, and they will stay cool for hours. It also works for food, water, or pretty much anything you can think of that you would want to keep cool/warm.
The obvious downside to this tote is that it only works for preserving heat. It’s great if you want to warm up bottles at home and bring them on a long ride. But if you’re looking for something that can heat up refrigerated milk, this is definitely not for you.
As for the tote itself, it is made from durable 600D oxford material. It is treated to be water repellent, which makes it suitable even for rainy day outings. The bag has a large capacity; it can fit two big bottles, as well as some additional snacks in the internal mesh pocket.
Also, the bag comes with a waterproof plastic insert, which will protect the interior of the bag from any leaks. In general, it’s definitely something you should have when traveling, but it does have somewhat limited functions.
The Munchkin Travel Car Baby bottle warmer is another great choice for road trips and outings. It comes with an adapter that plugs into the car’s lighter, and it is very easy to use. Additionally, the digital display shows you the remaining heating time, as well as the temperature of the milk.
The adapter has a light-up timer display, which is easy to use even at night. And the band that does the actual heating is elastic, so it can fit most baby bottles. But, it can also fit into most car cup holders, which is a huge bonus.
There are two downsides to this portable bottle warmer. First, it is pretty slow. If you want to warm up frozen milk, that will take about an hour. For room temperature milk, it’s some 20-30 minutes. Which is about ten times longer than your regular bottle warmer would take.
The other downside is the car adapter. It’s larger than it should be, and it doesn’t fit properly into most car lighters. I mean, you can squeeze it inside, but it will take some force and a pair of pliers to get it out. Which could mess up your car’s lighter for good.
Bottom line, it is a functional bottle warmer, but it is far from perfect. And it is pretty pricey as well – at some $40, it’s in the same price range as regular electric bottle warmers. Whether or not it is worth the money is a completely different issue.
One good thing about this portable bottle warmer is that it is versatile. You can use it as a travel bottle warmer – just activate the heating disk, and you’re good to go. It works for about an hour at a time, so it will heat up a bottle and keep it warm for that hour. Or you can use it as a cooler. Put in the fridge for 10-15 minutes, and you will have the same amount of cooling time.
But it does work in a weird way. It is in a liquid state, and when you activate the heater, the gel inside turns into a solid state. To reuse the warmer, you need to get the gel back into a liquid state. You can do that by putting it in boiling water, microwave, or a sterilizer for some 10 minutes.
That does mean that you can only use it once during a car trip or a flight, so it is a little bit awkward. It’s a good option as a quick solution, and it works pretty well. It will heat up frozen milk in about 30 minutes, which is not bad at all. And it comes with a little pouch, which is designed to protect you from the heat.
The Cherub bottle warmer fits bottles that are up to 12” in diameter. So, I think it’s safe to say that this can fit any baby bottle without issue.
There is one thing to keep in mind though – the gel inside the travel baby bottle warmer sleeve is in a liquid state. Which goes against TSA’s rule for liquids. I haven’t tried to take it on a flight yet, so I would advise that you check with the TSA. Especially if you won’t be bringing a backup warmer.
The bottle warmers in this section all need to be plugged into an outlet to work. They are portable because they are small and lightweight. I recommend these bottle warmers if you’re looking for something that you can use in hotels and apartments.
The New Munchin is a great bottle warmer. It can warm up milk and food, sterilize baby gadgets and it’s about as tall as an iPhone – pretty great, right? Size-wise it is extremely portable, and it will fit into most diaper bags and carry-ons. It is also pretty lightweight (about 20 ounces), so it won’t add “too much” weight to your already heavy diaper bag.
But you can’t use it anywhere. This baby bottle warmer has to be plugged into a source of electricity to work. It’s not great for road trips, long rides, or day-long outings – so any scenario in which you don’t have access to a power outlet. However, it is great to have in hotels and apartments, and even at the airport. And it can both warm up a bottle and just keep it warm.
So, how does it work? Simple – using the adapter that suits your brand of bottle (Dr. Brown’s Original, Avent, Medela, Tommee Tippee and some others) attach the bottle and press “go”. It heats it up and shows you the temperature as it warms. So, no water is needed, and super simple to use.
The bottle warmer can keep a bottle of milk warm at 98.6 degrees for 30 minutes. So, if you get distracted in the meantime, it should still be good to go when you are
If you are looking for a highly functional bottle warmer that is also a great option for home use, this Chicco one is a good choice. And it is also great for travel because of its small size and lightweight. It will easily fit into your carry-on or diaper bag, and it takes up as much space as a basic thermos bottle warmer.
The Chicco bottle warmer needs water to work, and it will shut off automatically when it runs out of water. It has a digital display that allows you to select the size of the milk bottle and how cold it is currently. The three options are room temperature, refrigerated, and frozen. It is compatible with most baby bottles and food jars, and it has a delayed start option.
However, it is not really designed to keep a bottle warm for prolonged periods of time. This is designed to quickly defrost milk or warm-up cold milk in just a minute or two.
Also, it is a little pricey, especially considering that the Babebay one is 50% cheaper, and it has the option to keep a bottle warm. But this does have a digital display and is pretty user-friendly. Just be sure to always test the milk on your wrist – the bottle warmer is inconsistent at times, and the milk can come out too hot/cold.
It’s a little bigger than the other two electrical bottle warmers I showed you, but it’s also pretty lightweight. At 1.5 lbs, this bottle warmer is actually weighs less than the thermos options, when you include the weight of the water that you also need to carry around.
I think it is a great choice for long holidays. Not only can it warm up a bottle of milk in just 3 minutes, but it also has the option to preserve the heat for hours. The only downside to this is that it doesn’t have a built-in timer, so you will need to track the warming time on your phone.
This bottle warmer has a pretty wide opening, and it can fit most brands of baby bottles. Obviously, it will fit all Philips Avent bottles perfectly, but it works just as well with other brands.
Now, there is one issue. The Philips bottle warmer works only with 110V, and it doesn’t support higher voltage. This is designed to be used in the US, so you should check the voltage of the country you are traveling to, to avoid any disasters.
Just like the other electrical warmers, this one needs water to work. It is very simple to use – just add some water inside the heater, and turn the dial to the setting you need. It is an efficient and versatile product, that just so happens to be extremely portable and affordable. And that’s why it is one of your favorites.
For me, there are two types. There are bottle warmers that have alternate power sources, like the ones that you plug into a car lighter. You can also get bottle warmers that use hot water in order to work – they are great for keeping bottles warm when you are walking around and don’t have access to any kind of power source.
USB bottle warmers are the best in theory and the worst in practice. In theory, you can just plug them into a power bank and they will keep the milk warm. But in practice, they can’t get hot enough, and they keep the milk lukewarm at best. Most have horrific reviews, which is why I won’t be featuring them here. The concept of a USB bottle warmer is amazing, but the execution of the idea is still nowhere near perfection.
The other type is bottle warmers that are small, lightweight but need to be plugged into an outlet. These are great if you are going on a holiday with your kids and you need something that’s smaller than your usual bottle warmer, but works just as well. They are great for hotels, and most of them fit easily into a carry-on.
So, I will divide this review into two sections. First I will show you bottle warmers that you can use without an outlet, which are great for warming bottles on the go. And then I will move on to small but powerful water bottles that are great for hotel rooms, apartments, layovers, etc. This brings me to my next point.
Do you need something that you can use to heat up the milk in the hotel room, or do you want something that allows you to warm up milk while you’re out and about?
If you need something to have specifically at the hotel room or apartment, I would highly recommend a compact bottle warmer that you plug into an outlet. For me, they are the most convenient choice, and the ones that I will show you in this review are all pretty small and lightweight.
And if you want a bottle warmer that you can use on the bus, plane, or when you’re sitting on a bench in the park, I highly recommend getting a thermos bottle warmer. These are two-part bottle warmers that feature a thermos and a warming cup. You carry around hot water in the thermos so that you can pour it over the baby bottle in the warming cup. They usually work pretty fast, but they can get a bit heavy to lug around all day.
These are also the more affordable option. They usually cost around $20, so they are the better option if you are on a tight budget.
Or maybe you are going on a road trip? If that is the case, the best option for you would be a bottle warmer that plugs into the car lighter. They are the most convenient because, unlike all other heaters, they don’t need water to work.
Are you looking for a product that can warm up a cold bottle of milk to a temperature that’s safe for your baby? Or something that will just keep a bottle warm for hours? Because it’s a huge difference. Whenever a product can only do one of the two things above, I will make sure to list it in the pros/cons section.
Products that are designed to heat up a bottle usually don’t do a great job at keeping that same bottle warm for hours. And vice versa. Obviously, there are some warmers that can do both, but they usually have to be plugged into a source of electricity. So, you should have a good idea of which is the better fit for your needs and travel habits.
Still not sure which travel bottle warmer is the right option for you? Don’t fret – here are our top three recommendations!
The Tommee Tippee is my recommendation for an on-the-go bottle warmer. You can use this on rides, in the park, and even on an airplane. It comes with a thermos that can keep water hot for hours on end, and is leak-proof. How long this takes to warm up a bottle of milk depends on the temperature of the water you pour in. For the best and quickest results, pour bottled water into the thermos.
The Munchkin bottle warmer is our top choice for road trips. Although it’s not really a perfect product, it still has more than 300 5-star reviews. There are some flaws to it, but it definitely works. It is pretty slow, but that milk will eventually be warm enough for your baby to drink.
The Munchkin fits into most cup holders, which is a huge bonus. And, because the band is elastic, it will fit over nearly all baby bottles.
The Philips Avent would be my top choice for a plug-in bottle warmer. It is small enough that it can fit in your carry-on, and it is super lightweight. And it is pretty versatile – it can heat up a bottle of milk in just a few minutes, and then keep it warm for hours.
Unfortunately, the Avent does not have a built-in timer, so you’ll need to use your phone to track how long it is working. But the affordable price, on top of all the other upsides, really makes this a great option.
