Keep your baby’s milk or water at the perfect temperature wherever you go! This USB-powered insulated bag gently heats and maintains liquids thanks to its built-in thermal sleeve and five-layer insulation. Simply plug into any 5 V USB source—laptop, power bank, car adapter—choose from low (40 °C), medium (50 °C), or high (60 °C) heat levels (long-press to switch temps), wrap your bottle snugly, and enjoy warm feedings on the move. The soft, durable fabric with a handy lanyard makes it stroller-friendly and ideal for travel. With thoughtful features like an easy-to-remove inner heating module for washing and universal fit for most baby bottles, this bag complements any parenting routine—stylish, safe, and oh-so-convenient.
