How to Use Your Refrigerated Travel Case for Insulin & Medicine

Whether you’re heading off on vacation, commuting into work, travelling abroad, or enjoying a countryside ramble, the RxCoolers Mini offers a practical and reliable way to keep your insulin and temperature-sensitive medicines properly cooled. 

With two convenient cooling options—one powered, one passive—it’s built to suit life on the move across the Europe and beyond.

You can either plug it in using a USB connection when electricity is available, or rely on the reusable Biogel cooling pack for off-grid peace of mind. Below, you’ll find step-by-step instructions for both methods.

Using the Biogel Cooling Pack (No Electricity Required)

Ideal for situations where you’re away from a power source—such as flights, coach trips, hiking holidays, or even just a long day out—the Biogel cooling method allows you to keep your insulin and medicines chilled without any need for plugs or charging.

Step-by-step:

1. Prepare the Cooling Pack: Shake the Biogel cooling pack four or five times to ensure the gel is evenly distributed throughout.
2. Freeze Thoroughly: Place the cooling pack in your freezer for 6 to 8 hours before use. It’s absolutely fine to leave it in longer—it won’t damage the pack.
3. Brief Defrosting: Before placing it into the cooler, allow the frozen pack to sit at room temperature for 10–15 minutes, or submerge it in lukewarm tap water for 2–3 minutes. This prevents frost from forming inside the case and protects your medication from accidental freezing.
4. Pack and Go: Dry the cooling pack thoroughly with a clean tea towel. Then load your medicines into the cooler, insert the cooling pack, and secure the standard lid (not the USB lid). You’re now ready to travel with your insulin and medicine safely cooled—no power required.

Cooling Performance with Biogel Cooling Pack

• Mild Temperatures (around 30°C): The RxCoolers Mini keeps your insulin and medicine refrigerated between 2–8°C for up to 30 hours, and cool below 26°C for up to 48 hours.
• Warmer Conditions (around 35°C): The RxCoolers Mini keeps your insulin and medicine refrigerated between 2–8°C for up to 28 hours, and cool below 26°C for up to 46 hours.
• Hot Weather (up to 40°C): The RxCoolers Mini keeps your insulin and medicine refrigerated between 2–8°C for up to 26 hours, and cool below 26°C for up to 44 hours.

Please note: real-world results may vary slightly depending on ambient temperatures and how frequently the lid is opened.

Using USB Power for Continuous Refrigeration while Travelling

When you’re near a power source—such as at home, in a hotel room, in the car, or have a portable power bank—you can use the USB-powered lid for constant refrigeration.

Works with most USB power sources, including:

• Portable power banks
• Car cigarette lighter adaptors
• Portable solar charging panels
• Standard household sockets with USB ports

How to use:

1. Load Your Medication: Place your insulin pens, vials, or syringes inside the cooler’s chamber as shown in the product images.
2. Close and Connect: Secure the USB lid, plug the cable into your chosen USB power source, and the cooler will begin chilling automatically. No buttons or programming required—simple and straightforward.

Cooling Performance with USB Power

• Up to 35°C: The RxCoolers Mini Refrigerated Travel Case maintains a constant refrigerated temperature between 2–8°C, as long as it’s plugged in.
• In Extreme Heat (40°C): It maintains a cooling range between 8–26°C, which is ideal for heat protection for your opened insulin pens or vial, but does not classify as refrigeration in medical terms.

Care, Cleaning & Maintenance of Your RxCoolers Mini

Your refrigerated travel case is a long-lasting medical device, so it’s important to give it the right care. Here’s how to keep everything running smoothly:

✅ Best Practices:

• Keep Upright: Always use and store the cooler in an upright position to ensure it functions correctly.
• Ventilation: Make sure the small heat-dissipation holes on the USB lid are never blocked.
• Dusting: Gently blow away any dust using a can of compressed air or a hairdryer on the cool setting every couple of weeks.
• Rest Periods: Unplug the USB lid for around 15–20 minutes every 4 days of continuous use to give the system a rest. This helps extend the life of the cooling component.

✅ Cleaning:

• Use a damp cloth to wipe the stainless steel body.
• For the USB lid and Biogel pack, use a dry, soft cloth.
• Avoid direct contact with water—especially near any electronic parts.

❌ Avoid the Following

• Don’t submerge any part of the cooler in water.
• Don’t use abrasive cloths or harsh chemical cleaners, as these can damage surfaces.
• Don’t leave the cooler plugged in non-stop for weeks without breaks. Like most electronics, it benefits from a pause now and again.

Additional Tips: If you notice any light marks or oxidation on the aluminium components, don’t worry—it’s a natural reaction and can be easily cleaned with a suitable aluminium polish.

With a bit of simple care, your RxCoolers Mini Refrigerated Travel Case for Insulin & Medicine will continue to deliver safe, reliable cooling for years to come—whether you're off to Cornwall for the weekend or catching a long-haul flight abroad!
