How to Use the Ceres Chill OG+ for Day Trips and Travel

Quick Answer

To use the Ceres Chill OG+ for day trips, start by chilling the inner chamber or adding ice, then pump or pour milk into the inner chamber, and use the outer chamber for storage or warming. This guide walks you through each step to keep milk cold for 24 hours and warm it when needed.

Traveling with breastmilk doesn't have to mean bulky coolers and ice packs. The Ceres Chill OG+ is a stainless steel chiller/warmer that keeps up to 28 ounces of milk cold for 24 hours and can double as a bottle warmer. Whether you're heading to a doctor's appointment or a weekend getaway, this guide shows you exactly how to use it.

We'll cover everything from prepping the chiller to cleaning it after use, with practical tips to avoid common mistakes. By the end, you'll be ready to hit the road with confidence.

What You Need to Know Before You Pack

The OG+ has two chambers: an inner chamber that holds up to 28 ounces and an outer chamber that can hold up to 38 ounces total. The inner chamber can be frozen beforehand to provide chilling power without ice, or you can add ice cubes to the outer chamber for a different cooling method. Knowing which method works best for your trip is the first step.

For short day trips, freezing the inner chamber overnight is the most convenient—no mess from melting ice. For longer travel, you might prefer using ice cubes in the outer chamber for easier temperature control. Both methods keep milk at a safe temperature for up to 24 hours, so choose based on your access to a freezer or ice.

• Check if your pump needs an adapter for direct pumping into the inner chamber.
• Always start with a clean, dry chiller to prevent bacterial growth.

Step-by-Step: Chilling and Storing Milk

First, prepare the chiller. If using the freeze method, remove the inner chamber and place it in the freezer overnight. If using ice, fill the outer chamber with ice cubes and close the lid. Make sure the inner chamber is securely in place before adding milk.

Next, pump or pour breastmilk into the inner chamber. You can connect a narrow-neck pump directly to the inner chamber for direct pumping, or use a funnel. Once filled, close the lid tightly. The chiller will maintain the cold temperature for the next 24 hours, so you can store milk safely while out and about.

• Don't overfill: leave a little space for expansion when freezing.
• Keep the chiller upright to avoid leaks.

Warming Milk on the Go

When it's time to feed, you can use the OG+ as a warmer. Simply pour warm water into the outer chamber (after removing any ice) and place the inner chamber with milk back in. The warm water will gently heat the milk to a comfortable feeding temperature.

This method is great for travel because you don't need a separate bottle warmer. Just find a source of warm water—like a cafe or restroom—and you're set. Always test the milk temperature on your wrist before feeding to avoid burns.

• Use water that's warm but not boiling to avoid overheating.
• Swirl the milk gently to distribute heat evenly.

Cleaning and Maintenance After Your Trip

After use, disassemble the chiller and wash all parts with warm, soapy water. The inner chamber is dishwasher-safe, but hand washing is gentler on the silicone seal. Rinse thoroughly to remove any soap residue.

Let all parts air dry completely before reassembling to prevent mold. Store the chiller with the lid off to allow airflow. Regular cleaning keeps your chiller ready for the next adventure.

• Use a bottle brush to clean the inner chamber thoroughly.
• Check the silicone seal for wear and replace if needed.

Your Travel Checklist

1. Prep the chiller: Freeze the inner chamber overnight or fill the outer chamber with ice before you leave. Checkpoint: Make sure the inner chamber is fully frozen or ice is fresh for maximum chill time.
2. Pump or pour milk: Connect your pump directly to the inner chamber or pour milk in using a funnel. Checkpoint: Avoid overfilling to allow for expansion and secure the lid tightly.
3. Keep it cold on the road: Keep the chiller upright and avoid opening it unnecessarily to maintain the temperature. Checkpoint: If you're out for more than a few hours, check the temperature periodically.
4. Warm when ready: Replace ice with warm water in the outer chamber to heat the milk gently. Checkpoint: Always test the milk temperature before feeding.
5. Clean after use: Wash all parts with soap and water, then air dry completely. Checkpoint: Store with the lid off to keep it fresh for next time.
