ZhiChu Portable Breast Milk Cooler 22oz – 360° Cooling, TSA-Approved

Meet the ZhiChu Portable Breast Milk Cooler, a compact, travel-ready chiller built around a 22-ounce capacity. Designed for busy parents, it blends practical storage with reliable cooling so you can adapt to a day of errands, commutes, or outdoor adventures without compromising feeding routines.

The heart of the system is 360° cooling tube technology that envelopes each bottle to help maintain a steady temperature without relying on extra ice. The outer shell is a durable, double-walled stainless steel that resists temperature shifts and daily wear, while the two BPA-free inner bottles keep milk separate and ready for use when needed.

All-day cooling, flexible storage

• 360° cooling tube technology supports long-lasting freshness for up to 24 hours without additional ice.
• Two BPA-free inner bottles (total 22 oz) allow flexible storage for different feeding scenarios.
• Rugged double-walled stainless steel and leak-proof lids help the cooler withstand travel and busy days.

Designed for travel and nighttime use

Certified TSA-approved for easier security checks, the ZhiChu cooler is made for moving through airports, car trips, or hotel stays. In nighttime routines, you can pump, store, and resume sleep with less disruption thanks to on-site cooling and simple handling.

• Lids with built-in seal rings minimize leaks during transit and in bags or backpacks.
• All parts detach for thorough cleaning, either by hand or in a bottle washer.

Simple setup and dependable care

To activate, freeze the cooling tube for about 12 hours (adjust as needed) and place it into the cooler for use. The design emphasizes straightforward operation, so you can pump, store, and go about your day with minimal fuss.

What’s included

• Two BPA-free inner bottles (together 22 oz)
• Cooling tube and lids with seal rings

Note: minor condensation can occur during transit as temperatures shift—this is normal and not a sign of compromise. When in doubt, a quick wash before first use keeps everything fresh and ready for your next outing.
