🌡️ At 35°C, the USB + Freeze Pack Cooler keeps insulin and medicines refrigerated between 2–8°C for 50 hours and cool below 26°C for 70 hours.

🌡️ At 40°C, the USB + Freeze Pack Cooler keeps insulin and medicines refrigerated between 2–8°C for 48 hours and cool below 26°C for 68 hours.

Explorer Cooling Performance on Freeze Pack Mode:

🌡️ At 30°C, the Freeze Pack Cooler keeps insulin and medicines refrigerated between 2–8°C for 33 hours, and cool below 26°C for 52 hours.

🌡️ At 35°C, the Freeze Pack Cooler keeps insulin and medicines refrigerated between 2–8°C for 30 hours, and cool below 26°C for 48 hours.

Explorer Cooling Performance on USB Only:

The USB lid alone cannot maintain refrigerated temperatures for insulin and medications. Instead, it is ideal for carrying open and in-use medicines cool and protected from heat, ensuring they remain at room temperature below 26°C.

This function operates efficiently in environments with ambient temperatures of 30°C, delivering the following cooling performance:

🌡️ At 30°C, the USB Insulin Cooler effectively lowers the internal temperature by up to 15°C compared to the external temperature. This consistent cooling mechanism maintains interior temperatures between 8–26°C for as long as it is plugged into a power source.

How to Use Your Cooler

To get the most out of your Explorer Travel Cooler, it’s all about mastering its ingenious three-in-one cooling methods. Versatile and adaptable, this travel case cooler works with USB power, cooling packs, or a clever combination of the two.

Follow this guide to use it properly and discover the cooling performance each method delivers.

1. DUAL MODE COOLER

For maximum cooling efficiency, the Explorer Insulin Travel Cooler – Medical Travel Case combines its Biogel cooling pack with the USB-powered lid. This dual cooling method ensures your insulin and medicines stay cool for up to three days, even in the height of summer.

Step-by-Step Instructions:

  1. Prepare the Biogel Cooling Pack: Give it a good shake, up and down, four or five times to evenly distribute the gel.
  2. Freeze the Cooling Pack: Pop it into the freezer for 6–8 hours. No worries if it stays frozen longer—it’s perfectly fine!
  3. Activate the Pack: Before using, submerge the frozen cooling pack in lukewarm tap water for 2–3 minutes to remove frost and prevent the risk of freezing your medications. If warm water isn’t available, leave it at room temperature for 15–20 minutes instead.
  4. Dry and Load: Towel-dry the pack, then place it into the cooling compartment alongside your insulin or medicines.
  5. Seal and Power Up: Secure the USB lid and connect it to a USB power source. That’s all there is to it!

2. COOLING CASE MODE

When you're off the grid or prefer to pack light, this medical travel cooler doubles as a simple cooling case. It's an ideal solution for air travel or remote adventures.

Step-by-Step Instructions:

  1. Switch the Lid: Replace your cooler’s USB lid with the regular lid.
  2. Prepare the Biogel Cooling Pack: Give it a good shake, up and down, four or five times to evenly distribute the gel.
  3. Freeze the Cooling Pack: Place the Biogel pack in the freezer for 6–8 hours. No worries if it stays frozen longer—it’s perfectly fine.
  4. Activate the Pack: Before using, submerge the frozen Biogel cooling pack in lukewarm tap water for 2–3 minutes to remove any frost. Alternatively, leave it at room temperature for 15–20 minutes. The warm water method is more efficient in all seasons.
  5. Dry and Load: Towel-dry the Biogel pack and place it into the cooling case alongside your insulin or medicines.
  6. Seal the Lid: Secure the regular lid, and you're ready to go!

3. USB COOLER MODE

While the USB lid alone doesn’t maintain refrigerated temperatures for insulin or medications, it’s perfect for keeping open and in-use medicines cool and protected from heat. It ensures they stay safely at room temperature below 26°C, ideal for ongoing use.

This function works effectively in environments with ambient temperatures up to 30°C, offering the following cooling performance:

  • At 30°C, the USB Cooler Mode lowers the internal temperature by approximately 15°C compared to the surrounding air, maintaining a consistent range of 8-26°C for as long as it remains plugged into a power source.

3-IN-1 INSULIN TRAVEL CASE COOLER

Whether you’re plugged into power or off on a wild adventure, the Explorer has got you covered with three smart cooling modes. Adapt to any situation and keep your insulin perfectly chilled, no sweat!

  • Dual Cooler Mode: Want the ultimate cooling performance? Use the USB lid and cooling pack together for up to 52 hours of refrigeration and 72 hours of cooling below 26°C. Talk about reliable!
  • Cooling Case Mode: Heading off the grid? Switch to the regular lid, grab the Biogel cooling pack, and enjoy up to 33 hours of refrigeration or 52 hours of cooling below 26°C. Perfect for camping, flights, or days without power!
  • USB Cooler Mode: Pop on the USB lid, plug it into any power source—be it your car, a portable power bank, or even a wall socket—and keep your medicine cool at a safe room temperature below 26°C for as long as you like.

For step-by-step instructions and detailed cooling capabilities, refer to the "How to Use" section above.

KEEP YOUR INSULIN COOL FOR 3 WHOLE DAYS WHILE TRAVELLING

Braving a sizzling summer? No problem! Combine the USB lid with the Biogel cooling pack, and you’re all set for up to three days of perfectly chilled insulin and medications. Whether you’re hitting the beach, hiking in the hills, or jetting off on an adventure, your meds are sorted.

STORE UP TO 7 INSULIN PENS WITH EASE

With its spacious 8.4 cm diameter and 900ml interior volume, the Explorer Insulin Cooler can hold up to 7 insulin pens, 28 Humulin vials, or 8 Novolog vials. Perfect for those who need to bring along a substantial amount of medication on their journeys.

PERFECT FOR REFRIGERATED & ROOM-TEMPERATURE MEDICINES

When used with the cooling pack or in combined mode, the Explorer excels at keeping your insulin and medicines refrigerated at low temperatures between 2-8°C.

For those, the USB mode is your best bet! It keeps your meds at a safe room temperature below 26°C for unlimited periods when plugged into a power source, provided the ambient temperature is 30°C or lower.

Frequently asked questions

How Does The Explorer Insulin Travel Cooler's 3-In-1 System Work?

The Explorer Insulin Travel Cooler operates across three completely independent cooling configurations, giving you more flexibility than any other medical cooler out there.

In Biogel-only mode, you use the regular lid with the included Biogel Cooling Pack for passive cooling with no power needed — ideal for flights, off-grid trips, or any situation where cables just aren't practical.

In USB-only mode, you connect the electric lid to any USB power source to keep open, in-use medicines cool at room temperature below 26°C.

In combined mode, you use both the electric lid and the Biogel Cooling Pack together for maximum cooling performance — the best choice for long trips, extreme heat, or multi-day travel.

Switching between modes takes seconds — simply swap the lid and add or remove the Biogel pack as needed.

How Long Does The Explorer Travel Cooler Keep Medicines Cold?

Cooling performance and duration varies by mode and outside temperature.

In combined mode (USB + Biogel), the Explorer keeps medicines refrigerated (2–8°C) for up to 48–52 hours, and cool below 26°C for up to 68–72 hours, depending on outside temperature.

In Biogel-only mode, it keeps medicines refrigerated for up to 28–33 hours, and cool below 26°C for up to 46–52 hours.

In USB-only mode, the cooler keeps medicines cool below 26°C (not fully refrigerated) for as long as it stays connected to a power source, at ambient temperatures up to 35°C.

Can I Use The USB Mode Alone To Refrigerate My Insulin?

No — on the Explorer, the USB lid alone can't maintain fridge temperatures. In USB-only mode, the Explorer works as a heat-protection cooler, keeping the internal temperature roughly 15°C cooler than the outside environment — suitable for open, in-use medicines that should be kept cool but not re-refrigerated.

For full refrigeration, always use the Explorer with the Biogel Cooling Pack, either in Biogel-only or combined mode.

💡 If you'd like USB-powered refrigeration without a Biogel pack, have a look at the Voyager Travel Fridge, the Voyager Mini, the Pioneer Portable Refrigerator, or the Pioneer PRO.

Can I Use This Travel Cooler To Carry Open, In-Use Insulin Or Medicine At Room Temperature?

Yes — but only in USB-only mode. When used with the electric lid connected to a power source and without the Biogel pack, the Explorer keeps medicines cool below 26°C at room temperature, which is suitable for open, in-use insulin.

In Biogel or combined mode, the Explorer maintains full fridge temperatures (2–8°C), which may be too cold for some types and brands of insulin or medicine once opened. Always check your specific medicine's storage instructions beforehand.

💡 For purpose-built heat-protection coolers that don't need full refrigeration, the Rambler, the Rambler Pro, or the Chiller cooling pouches are excellent alternatives.

How Many Insulin Pens And Vials Fit In The Explorer Insulin Travel Cooler?

The Explorer Insulin Travel Cooler holds up to 7 standard-format insulin pens available in the UK (Lantus, NovoRapid, Toujeo, Admelog, Novomix, Apidra, Actrapid, and others) and up to 6 pens of wider formats (Humalog, Tresiba, Levemir, Fiasp, Basaglar, Ryzodeg, and others).

It also holds up to 28 Humulin vials or up to 8 Novolog vials, making it ideal if you rely on vials rather than pens.

🔍 Check the full compatibility list in the product images or feel free to contact our support team for personalised advice.

Can I Use The Explorer Travel Cooler For GLP-1 Medicines Like Ozempic or Mounjaro?

Absolutely! The Explorer Insulin Travel Cooler is a great travel cooler for GLP-1 medicines.

It holds up to 5 Ozempic or Wegovy pens, up to 6 Saxenda pens, up to 7 Victoza pens, and up to 3 Mounjaro or Trulicity pens, among many others.

🔍 If you're not sure about your specific medicine or pen format, feel free to contact our support team for personalised advice.

My Medicine Is Not On The Compatibility List. Can I Still Use The Explorer?

Very likely, yes! The compatibility lists cover the most commonly prescribed medicines in the UK but aren't exhaustive. What determines compatibility is primarily the physical size of your injection device — whether your pen, syringe, or vial fits within the internal chamber (4.9 cm internal diameter, 20 cm usable length).

🔍 If your medicine isn't listed, have a look at the dimensions on the product images, or get in touch with our support team with the name and format of your medicine and we'll be happy to confirm compatibility for you.

What Power Sources Work With The Explorer Insulin Travel Cooler?

The Explorer's USB lid uses a USB-C to USB-A cable (included) and plays nicely with any standard USB power source — power banks, car cigarette lighter adapters, solar panels, and household USB wall adapters. This makes it equally practical for road trips, camping with a solar panel, flights with a power bank, or plugging in at a hotel or the office.

💡 Heading off on a longer trip? The 4AllFamily Pathfinder 20,000 mAh power bank is a purpose-built companion for continuous cooling on the move.

What Is The Biogel Cooling Pack And How Do I Use It?

The Explorer Insulin Travel Cooler includes a Biogel Cooling Pack that uses a non-toxic natural gel with a freezing point of 2°C — meaning it can't freeze your medicine on contact.

To prepare it, give the pack a few shakes, freeze for 6–8 hours (or leave it in the freezer for longer), then submerge it in lukewarm tap water for 2–3 minutes before use to remove any surface frost. Dry it gently, then pop it in the cooler alongside your medicines.

💡 The Biogel Cooling Pack is reusable indefinitely. Additional packs are available here for swap-and-go extended cooling.

Is The Explorer Really Safe and Reliable For Medicine Storage?

Absolutely — and the safety is built in at multiple levels.

  • The cooler has been laboratory tested to confirm its cooling performance across a range of ambient temperatures.
  • The inner chamber is made from food-grade stainless steel 304, safe for direct contact with medicine containers.
  • The Biogel Cooling Pack uses a non-toxic natural gel with a freezing point of 2°C, so it physically can't drop below the safe lower boundary of fridge temperature and freeze your medicines.
Can I Fly With My Cooler? Can I Pack It In My Hand Luggage?

Absolutely! Like all 4AllFamily's medical cooling cases and mini fridges, the Explorer Insulin Travel Cooler is fully approved for airport security and can be carried through in your hand luggage — whether you're flying from a UK airport, within the EU, or on international routes.

💡Do make sure to carry your medicines inside the cooler to show it's being used for medical purposes — this makes getting through security nice and straightforward.

I Only Need To Carry 1–2 Injection Pens Or Syringes. Do You Have A Smaller Travel Cooler?

Absolutely! The Explorer Insulin Travel Cooler is designed for those who need to carry multiple pens or vials. If you only carry 1–2 pens a day, a more compact cooling case might suit you better.

💡 For refrigerated storage, the Nomad Medium is a slim, passive cooler that works with the Biogel Cooling Pack. The Voyager Mini adds USB electric cooling on top of the Biogel system in an equally compact format for up to 3 pens.

💡 For heat protection only (open, in-use medicines at room temperature), the Chiller pouches, the Rambler, or the Rambler Pro are purpose-built for that.

🔍 Not sure which cooler is right for you? Get in touch with our support team and we'll help you choose!

What If I Lose The Biogel Pack Or The USB Lid — Can I Replace Them Separately?

Yes! And this is one of the things that makes 4AllFamily's medical cooling cases such a great long-term investment.

Every component is available separately, so you never need to replace the whole cooler if one part is lost, damaged, or worn out.

🔍 Replacement Biogel Cooling Packs and USB cooling lids are available on our accessories page. It's also well worth having a spare Biogel pack for longer trips — simply freeze one while the other's in use for continuous, uninterrupted cooling.

What Is The Return And Warranty Policy For The Explorer?

Not quite what you were after? No worries — you've got 30 days from delivery to request a return.

🔍 Have a look at our return policy page for the full details.

Your Explorer also comes with a 1-year warranty, and if you'd like a bit of extra peace of mind, you can add up to 3 more years of cover at checkout for a small fee. We cover all defects and malfunctions — just not scratches, everyday wear, or accidental damage.

And of course, our Lifetime Customer-Oriented Support team is always on hand — just give us a shout, whatever you need.

Ideal for Insulin, Ozempic, Mounjaro, Wegovy, Zepbound, and 30+ Medications!
