4ALLFAMILY Explorer Insulin Cooler Travel Case TSA Approved 72H (1–7 Medication Pens) – On–The–Go Medical Cooler with Biogel Ice Pack – Diabetes Travel Case for Insulin Pens & EpiPens (Blue)

Two products purchased from 4AllFamily, the Nomad Big 48H and the Explorer 72H. The Nomad is well made and kept my medications cold for well over 24 hours, until refrigeration. It held 2 large prefilled syringes, 1 pen auto injector and 2 BD needles, with room to spare. US TSA inspected my carry-on bag on numerous trips, without any questions or concerns with the Nomad cooler and “frozen” biogel ice pack. If the biogel ice pack isn’t frozen on the return trip, pack it in a checked bag.4AllFamily has an amazing customer care team and takes quality control issues seriously!I recently purchased the Explorer 72H. Although functioning, there was an issue with the product. I sent a message with pictures and my concerns about using the product directly to 4AllFamily (not Amazon) on 1/23/25. I received a prompt and very polite response from Maria C. She assured me that I would receive a new item for my upcoming travels and followed up with me several times. I received the replacement item on 1/25/25, just 2 days after my initial contact with 4AllFamily. I commend 4AllFamily for valuing their customers and for excellent customer service.

This little cooler worked great for my 7 day road trip travel in California. My insulin pens and Ozempic pen stayed perfectly cold

The product works as advertised. Easy to use and carry.

Used it for the first time the day I received it. It kept my medicine cold 9+ hours. with a lot of chill left in it. Just with the Gel Pack that was included. You can see that it is made with quality materials and very sturdy

I bought this product to carry my insulin pens on a trip to Europe. The pros: the outside canister is great. It is metal so can't break, large enough to hold the biogel plus 3 Lyumjev and 2 Lantus solostar pens. The biogel really does last a long time (long enough for a flight from San Francisco to Milan with a 2 hour layover). Cons: the cap with the fan and charging cord doesn't really do much. The fan has started up consistently, but without the frozen biogel, it doesn't really cool the container down. Also, the insulin pens get really cold if they are placed right next to the frozen biogel. I wasn't sure if they might freeze, so I wrapped the biogel in one layer of bubble wrap. This reduced the number of pens the container holds from six to five. But since five pens are more than enough for my trip, that wasn't a problem for me. Summary: Overall, I love this product since I have spent years carrying my pens onto planes with frozen water bottles, etc. I've read reviews that said the container is too big, but I found the size to be just right. It fits easily into my small backpack. I guess the peace of mind it brings is it's greatest benefit. It just needs a better fan.

I bought this cooler to keep my injectable osteoporosis medicine cool during a three-week trip to Europe. While the pen does not need to be refrigerated, it must be kept cooler than 80 degrees. Knowing that I would not have access to a refrigerator and would be traveling by airplane, train & car, I needed to be assured that it would stay cool enough in whatever space it was in. It plugs into a USB port or car lighter and keeps the medicine at a cool temperature. The first several days we were there the temperature was in the 90s and air conditioning was not always guaranteed so I was happy to know that I would not lose my medicine due to high temperatures. I highly recommend this product for traveling with temperature sensitive medicines!

I recently went on a vacation where we drove through California. We didn’t know how long we would be out of the car for at the time and wanted to make sure my insulin stayed at the right temperature while we traveled. Everything went great through TSA, except for the fact that the agent had to mess with me. With the straightest face in the world told me that I could not take it with me. I almost had a heart attack. He started laughing and I couldn’t even believe he could hold it together as long as he did, but thank God it is TSA approved. I used a portable battery as well as the usb in the car and both worked perfectly. I did test it with a different portable battery and it kept turning the fan off, that was more the portable battery’s issue. My other 2 worked great, I would just recommend doing test runs with your means of charging prior to your trip just to make sure you’re good. This comes in handy too living in south FL if we lose power from a hurricane for extended periods of time. Yes it may be slightly more expensive than other items, but I did my research and this definitely seemed like the most reliable option. Especially if you want both the options of cooling fan or no additional fan like I did. I used a 32oz drink holder that had a pocket so I could charge while hiking without taking out of the holder.

I travel for a living and take injections. The frozen insert does everything it claims, keeps my medicine at the cold through even the longest airline delays, even in this summer’s intense heat. The true test is when I got to my latest destination and the refrigerator was broken. I used the cooling top for the first time and I’m blown away. It’s been a full day, my frozen insert is still completely frozen due to the cooling top and my medication is still safe. In the pictures I’ve scratched off the frost to show how cold the cooling top stays. This is worth every penny and works better than I expected. Thank you for this wonderful product!!
