Charging

Your device is powered by a rechargeable battery. A USB-C cable and power adapter are included.

The USB charging port is located on the back of the warmer. When not charging, ensure the USB port cover is securely closed.

The device can be fully charged in approximately three hours. When the device is powered off, a quick press of the control button will display the battery life, ranging from 99% full to 20% low. During use, if the battery level drops below 20%, the display will flash “LO” to indicate that it’s time to charge.

Note: To avoid injury or damage, do not use incompatible, worn, or damaged batteries, chargers, or cables. Using other charging devices or batteries may void the warranty and cause damage to
the device.

The adjustment of voltage and output power depends on the connected device and is performed automatically.

Powering On and Off

To power on your Stellar™ Portable Baby Warmer, press and hold the control button located at the front of the device for two seconds. This will activate the device and enter Temperature Setting mode.

To power off, press and hold the control button again for two seconds. A single beep will indicate that the device is off.

Temperature Setting

The device offers four temperature settings: 37ºC, 40ºC, 45ºC, and 50ºC.

When powered on, the device enters Temperature Setting mode, automatically activating the last used temperature. To adjust to your desired temperature, press the control button again.

Once the desired temperature is reached, the warmer will emit a sequence of three beeps. The liquid will then be maintained at this temperature until the warmer is powered off.

Note: It is not recommended to prolong the keep-warm mode for breast milk beyond 20 minutes or to reheat breast milk more than once, as this may encourage bacterial growth.

Cleaning

Cleaning your Stellar™ at Home

  1. Ensure the device has cooled down before cleaning.
  2. Confirm that the USB port cover is securely closed and that the device is not charging.
  3. Remove the silicone ring.
  4. Carefully wash the silicone ring, then wipe down the warmer with a dishcloth. Finally, rinse off the warmer and dry it with the warming plate facing down.

Cleaning your Stellar™ on the Go

  1. Ensure the warmer has cooled down and is not charging.
  2. Confirm that the USB port cover is securely closed.
  3. Remove the silicone ring and clean it carefully with a wipe.
  4. Wipe down the inside of your Stellar™ warmer.

Cleaning Bottle Adapters

  1. Remove the silicone ring.
  2. Wash both the adapter and silicone ring gently with warm water and mild dishwashing detergent.
  3. Let them air dry.

Caution: Never submerge your warmer in water, or place it in a microwave or dishwasher.

Note: When washing your warmer, always ensure the silicone port cover on the back is securely closed. Any liquid entering the battery compartment could damage the device.

Sterilizing

We recommend sterilizing your bottle warmer as often as possible using either the traditional water and vinegar method or our Lumen™ Portable UV Sterilizer.

Baby Bottle Compatibility

Stellar™ Portable Baby Warmer is compatible with leading European baby bottle brands and can be used with the following bottles:

No Adapter Needed: Philips AVENT.

Adapter Required: BIBS, Dr. Brown’s, Lansinoh, MAM, Medela, NIP, NUK First Choice, Suavinex Zero Zero, and Tommee Tippee.

Boil Dry Protecction

The boil dry protection feature automatically turns off the heating element when no water is detected. The device will emit three beeps and display "HO" on the screen, indicating it has entered Boil Dry Protection mode.

To resume using the appliance, turn it off, fill the baby bottle with refrigerated or room temperature liquid, securely attach it to the warmer, and restart the device as usual.

Silicone Seals and Bottle Adapters

To ensure the Stellar™ Portable Baby Bottle Warmer remains 100% leak-proof during warming and to protect the device from potential damage caused by liquid exposure, it's essential to use the appropriate sealing rings for both the heating plate and bottle adapters.

Both the heating plate and bottle adapters are equipped with food-grade silicone rings/gaskets. Before each use, check that these rings are in good condition and correctly inserted into the warmer and bottle adapter, if one is being used.

These sealing rings are wear-and-tear parts and should be replaced regularly. Additionally, it is crucial to use the bottle adapter that matches the brand of the baby bottle you typically use for feeding, as this helps prevent leaks and any associated damage.
