USB Baby Bottle Warmer Sleeve

The USB Baby Bottle Warmer Sleeve is a practical and portable solution for keeping your baby's milk warm at the perfect temperature — anytime, anywhere. Designed with adjustable Velcro straps, this warmer fits most standard baby bottles (55–80mm diameter) and ensures a secure hold.

Made from durable PU leather and equipped with a four-layer insulation system, including a built-in heating element, this bottle warmer sleeve effectively retains heat. It offers three temperature settings — 45°C, 55°C, and 65°C — with intuitive 3-color LED indicators for easy control.

Ideal for travel and daily use, the sleeve connects via USB to power banks, car chargers, or wall adapters, making it a reliable on-the-go bottle warming solution. Whether you're on a walk, in the car, or at home, your baby can enjoy warm milk whenever needed.
