Whether you’re breastfeeding or bottle feeding, there may come a time when you need to warm some milk for baby on the go—and whether it’s a family vacation or a day trip to grandma’s, we all know babies don’t exactly like to be kept waiting! That’s where a portable bottle warmer comes in.

Portable bottle warmers come in several varieties; some work via heat induction, others by keeping hot water in a thermos for later use. They can be powered by rechargeable batteries, wall sockets, or even no electricity at all! Keep reading to learn more about what to look for in a travel bottle warmer, then shop our favorite picks for the best portable bottle warmers on the market right now.

What to Look for in a Travel Bottle Warmer

The first thing to consider when you’re looking for a bottle warmer is how you’ll use it. If you’re looking for a smaller model that’ll use up less shelf space at home and pack well into a suitcase for setup at your destination, a smaller model of a normal bottle warmer—the type that plugs into a wall socket—will get the job done. If you want something for use in a car or on a hiking trip, you’ll need something that’s not tied to a power source. You might want a rechargeable, battery-powered bottle warmer or an electricity-free thermos-style option. But whichever model you choose, we’ve gathered a few things to consider when shopping for the best portable bottle warmer:

  • Size. Will the bottle warmer sit on a hotel bedside table? Or does it need to be stashed in a diaper bag? Bottle warmer sizes vary, and some are bulkier than others. For the utmost in on-the-go convenience, a thermos-style portable milk warmer makes a great option.
  • Power source. The earliest bottle warmer models operated by plugging them into an electrical socket. But today, you can find rechargeable USB bottle warmers or cordless bottle warmers that operate using batteries. Consider what, if any, power source you might need before shopping.
  • Ease of cleaning. When it comes to anything related to babies, convenience and cleanliness are key! Look for a travel bottle warmer that’s easy to clean, rather than having tons of parts to remove and replace before using.

And when it comes to feeding baby, keep in mind that the Centers for Disease Control and Prevention (CDC) recommends using breast milk within two hours of coming to room temperature. So if you use a portable bottle warmer to warm milk, it’s important that you feed it to baby right away. In addition, it’s never safe to refreeze milk that has been thawed or warmed in a bottle warmer. Need more info? Check out our guidelines for storing breastmilk.
