  2. The gentle steam heats your bottle and jars evenly in just a little over a minute.

  2. If you’re looking for something stylish to add to your travel gear, this one has a sleek and elegant design that’s pretty simple to use.”


  1. The steam system in the sterilizer tends to make the bottle too hot to the touch, so be careful with that!

  1. In just two minutes, the sterilizer can either clean up to four 9-ounce bottles, or two Avent breast pumps in the interior rack in one go.

  4. The sterilizer has two side grips for easy insertion and removal from the oven. These side grips stay insulated and cooler than the rest of the sterilizer, so don’t worry about burning your fingers!


  1. Customers complain that the jars are sterilized, but not always dried.

Chicco Baby Bottle Steam Sterilizer 3-in-1

Having trouble finding a versatile bottle sterilizer for home and travel? Check out the Chicco Baby Bottle Steam Sterilizer.

In compact mode, it efficiently cleans fewer bottles while conserving power.


  1. The portable sterilizer works in normal full-size mode, compact eco, and microwave, giving you added flexibility depending on your circumstances.

Baby Brezza Bottle Sterilizer and Dryer

For a family with too many juniors, a smaller sterilizer just doesn’t cut it. You need a sterilizer that can take in the bulk of your little ones’ used bottles, nipples, and feeders and get the job done in a whip.

Meet the Baby Brezza Bottle Sterilizer and Dryer. This beast of a sterilizer can cleanse 8 bottles, and two full breast pump sets in one go, and finish a cycle in just half an hour!


  1. One standout feature is its impressive capacity. Apart from accommodating 8 bottles, it also includes a middle compartment designed to hold the nipples and lids of these bottles. Note that taller bottles might not fit in the middle compartment.
  2. The sterilizer has four different modes: Dry, Sterilize, Dry & Sterilize, and Store. Thanks to the size of it, you can leave your bottles in it for storage instead of leaving them out in the open, ensuring hygiene as well.
  3. The entire sterilizer has a modular structure. This means you can use the different compartments in any preference, depending on your needs. Be it in its full size or using just its top bin, the sterilizer works great.
  4. The drying cycle offers flexibility with options for 30, 45, and 60 minutes, allowing you to adjust according to the size of your jars and accessories requiring drying.


  1. The bulky size of the sterilizer makes it a bit of a challenge to carry it around when you’re on the move. However, it can also double as a storage compartment, avoiding the need for any additional bags or boxes.
  2. The Baby Brezza Bottle Sterilizer does have a much larger footprint, in terms of space occupancy as well as power consumption.

  1. What is the best bottle sterilizer for travel?

A travel bottle sterilizer can be a game-changer for parents with babies on the go. The ideal sterilizer choice often hinges on the family’s specific requirements, like the number of bottles to clean, access to electricity or microwaves, storage space, power consumption, and more. 

  1. How do you sterilize bottles when traveling?

The most reliable method for sterilizing baby bottle accessories involves submerging them in boiling water for roughly five minutes. However, that can be quite a task when you’re away from home.

This is where a bottle sterilizer comes in handy! Some models rely on electricity, while others are suitable for quick cycles in the microwave.

For more in-depth information on these options, check out the details mentioned above.

  1. Is it okay to leave bottles in the sterilizer overnight?

Most bottle sterilizers turn off automatically when the cycle is over, allowing you to set them up at night, head to bed, and they’ll be ready in the morning. Additionally, most sterilizers ensure complete hygiene for almost 24 hours as long as they are left untouched, making them absolutely clean even after a whole night in the compartment.

  1. Do I need to dry bottles after sterilizing?

Ensuring that your jars are completely dry before introducing formula or baby food is crucial. Bacteria thrive in damp environments, so a thorough drying process is essential to prevent their growth.

Some portable sterilizers come with the added advantage of drying bottles before use.
