On-the-go cooling for busy parents

The ZhiChu Portable Breast Milk Cooler is a compact companion for travel, workdays, and outdoor adventures with your little one. Its 360° cooling tube surrounds two inner bottles, delivering steady temperature control without the need for extra ice. In real-life use, you can grab it from the car, slip it into a diaper bag, and feel prepared for feeding moments away from home.

What’s included and how it works

Inside you’ll find two BPA-free inner bottles with a total capacity of 22 oz. Each bottle has an integrated lid and seal ring to help prevent leaks, and you can use them independently to separate warm and cold milk for feeding flexibility.

• 360° all-around cooling tube technology provides steady cooling without ice
• Two BPA-free inner bottles (22 oz total) with built-in lids and seals
• Durable double-walled stainless steel construction for travel readiness
• TSA-approved for hassle-free airport security checks

How to use and care for best results

To prep, freeze the cooling tube for about 12 hours at around 0 ℉, then place it into the cooler. The independent bottles can store warm or cold milk, giving you flexibility during outings and overnights.

• Freeze the cooling tube for 12 hours, then assemble for easy use
• Nighttime pumping is made easier by having milk ready by the bedside
• All parts disassemble for simple cleaning by hand or in a bottle washer

Real-life scenarios and benefits

Whether you are commuting, flying, or enjoying outdoor activities, this cooler is designed to fit into your routine. The double-walled steel helps withstand warmer environments, while the two bottles offer options for temperature management and quick feeding moments when time is tight.

Care and safety notes

All components are removable for cleaning. If you notice condensation during transit, that is normal and does not indicate a defect. Clean before first use and ensure all parts are dry before storage.
