An 80% charge can be achieved in approximately 1.5 hours, with a full charge taking about 2 hours. The LED display will indicate the battery level.
4.2 First Use Cleaning
Before adding any liquid, clean the inner stainless steel container and the lid components thoroughly with warm water and mild soap. Rinse well and ensure all parts are dry before reassembling.
5. Operating Instructions
5.1 Filling the Warmer
Unscrew the top lid. Pour up to 17 ounces of breastmilk, formula, or water into the food-grade 316 stainless steel inner container. Ensure the liquid level does not exceed the maximum fill line. Securely screw the lid back on.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on. | Low battery or no charge. | Charge the device fully using the provided USB-C cable and an 18W+ adapter. |
| Liquid is not heating up. | Insufficient liquid, device not properly sealed, or not in heating mode. | Ensure adequate liquid, check lid for proper seal, and confirm device is in heating mode (not just 'Keep Warm'). Avoid using while charging. |
| Device leaks. | Lid not properly secured or child-safety lock disengaged. | Ensure the lid is tightly screwed on and the child-safety lock is engaged. Check silicone ring for proper placement. |
| Battery life is shorter than expected. | Frequent use, very cold initial liquid temperature, or aging battery. | Ensure full charge before use. For very cold liquids, heating takes more energy. If issues persist, contact customer service. |
