Portable bottle warmer

How long does it take to heat up to the desired temperature?

The heating-up time mainly depends on the original liquid temperature, the quantity of the liquid and also which temperature setting you want.

Normally it takes anywhere from 4-10 minutes.

How long does the battery last?

The battery can last up to 8-12 hours of heating.

How many times can I warm your bottle?

You can heat up a bottle 8-10 times. Creating heat takes a lot of energy so if you are using smaller amounts of liquid you can get more heatings for each charge. When using refrigerated liquid it will take longer to heat and pull a lot more energy from the battery.

Where is the O-ring as shown in the instruction brochure?

The O-ring has been already placed in the device.

Does Warmer Lab’s portable bottle warmer work with breast milk and formula?

Yes! Our Pro 2.0 (as long as the Minor Set & Gift Set) works with breastmilk and pre-made formula, which our slow heat technology preserves nutrients and eliminates the risk of hotspots. But it does not work with some ready-to-use formula, please leave us messages for more info.

The better solution for formula powder on the go is to heat up water, then adding powder.
Hope you enjoy the benefits of our product!
