That's where a reliable insulin travel case becomes the essential companion for diabetic travelers and outdoor enthusiasts. Such cooling cases keep your insulin cool and safe, so you can enjoy your travels without worrying about your medication.

Different Types of Insulin Travel Cases and Coolers

Insulin cooling cases come in different sizes, designs, and styles to accommodate various insulin devices, including insulin pens, vials, cartridges, or even prefilled syringes.

The very first thing to consider when choosing your insulin travel case is whether you'll be carrying unopened refrigerated insulin or opened insulin supplies at room temperature:

• For unopened insulin, your travel cooler case must maintain refrigerator temperatures. This is crucial.
• For opened insulin, you can opt for a cooling case that maintains temperatures below 25°C and protects your insulin from the heat.

To help you understand your options better, we've created a video guide that showcases the different types of insulin travel cases and coolers. You'll see firsthand how each type can meet your specific travel needs, with detailed explanations also provided below.

Travel coolers for opened insulin

These insulated travel cases, including bags and hard shell coolers, are engineered to keep insulin cool at safe room temperatures below 25°C, but not as cold as refrigerated conditions during travel. They come in various sizes and shapes to accommodate insulin pens, vials, or both.

These are ideal for transporting your in-use insulin during day trips or summer vacations. They typically work with freeze packs or evaporative cooling technology to maintain the temperature cool inside.

Our Top Picks for Opened Insulin Travel Coolers:

• The new Chillers Advanced Insulated Travel Cases that keep insulin cool for more than 45 hours without ice or electricity.
• The Rambler Small Insulin Pen Travel Case that keeps one insulin cool for up to 12 hours.
  

Refrigerated travel cases for unopened insulin

These compact, travel-size, portable refrigerators keep your insulin refrigerated at a consistent temperature between 2°C to 8°C during transport. Designed to carry unopened insulin pens or vials, they are ideal for extended travels where refrigeration isn't readily available.

Some refrigerated travel cases for insulin operate on electricity and can be powered by internal batteries or external USB sources. When not utilizing their battery power, these medical travel fridges can be plugged into USB-powered sources such as a standard wall outlet, a car's cigarette lighter, a travel power bank, or even a portable solar panel, making them suitable even for off-grid adventures.

Additionally, some models function without electrical power, using freeze packs to keep your insulin refrigerated while traveling.

Insulin storage for travel

Typically, unopened insulin must be refrigerated between 2°C to 8°C. Once opened, your pens or vials can be stored at room temperature (25°C) for about a month, although the exact shelf life of insulin at room temperature varies depending on the brand and type. For instance:

• Humalog and Novolog can be stored at room temperature for up to 28 days.
• Lantus can stay unrefrigerated for 28 days.
• Levemir (discontinued in 2024) can stay out of the fridge for up to 42 days.
• NovoLog Mix 70/30 and Humalog Mix 75/25 can only be stored at room temperature for 14 days.

However, it's vital to ensure that even when unrefrigerated, insulin is never exposed to temperatures over 25°C, even briefly.

Therefore, temperature control is crucial when traveling with insulin. Planning ahead and equipping yourself with a suitable insulin travel case cooler will help keep your insulin safe and effective throughout your journey.

What to Look For in an Insulin Travel Case Cooler?

When choosing an insulin travel case, it's essential to consider your specific needs and preferences. Look for a durable, lightweight, and easy-to-carry case. Additionally, the storage capacity and level of insulation or refrigeration are important to meet your needs. Here are some key features to consider:

• Insulation & cooling performance: The travel case should have proper insulation to keep insulin and other medications at the right temperature range during transport. If you need to keep insulin refrigerated, look for a more powerful travel case that can maintain a temperature range of 2°C to 8°C for at least several hours.

• Size and storage capacity: Choose a case that offers enough storage capacity to carry all your insulin. Think about how many insulin pens or vials you need to transport during travels, as well as maybe other diabetic supplies such as lancets, test strips, and glucose meters.

• Quality and durability: Look for an insulin travel case made from high-quality, durable insulation materials that can withstand the rigors of travel. Consider whether the case is water-resistant or waterproof and has a sturdy outer shell to protect your insulin pens and vials from impacts or bumps.
• Air-travel approval: If you're flying with insulin, make sure your insulin travel cooler complies with airport security regulations and airline policies for carrying medical supplies on board. All 4AllFamily insulin coolers are designed to meet international travel standards and are suitable for use at South African airports. For the most accurate and up-to-date guidance, we recommend checking the Airports Company South Africa (ACSA) website or contacting your airline directly.
