It uses evaporative cooling technology that you can use with just water and the open air. I used it for insulin during the desert section of the PCT.

I ultimately ended up going in a different direction, but this is definitely THE option to use.

My husband uses [these] (https://smile.amazon.com/Insulin-Cooling-Reusable-Evaporative-Medication/dp/B0002262DA/ref=sr_1_4?crid=18OGO3UXLWFA9&keywords=insulin%2Bcooler%2Btravel%2Bcase&qid=1563473297&s=gateway&sprefix=insulin%2Bcooler%2Caps%2C164&sr=8-4&th=1) to keep his refrigerated eyedrops cold when we travel. They're designed to keep insulin cool, but will work on other things too! It doesn't keep them refrigerator-cool, but definitely below room temperature, which I'm guessing will be cool enough, though definitely check with your doctor or pharmacist to confirm.

Seriously though, where do you plan on going? And what do you plan on doing?

Regardless, grab a Frio pack. It'll work in 95% of the world. It doesn't need power and cools by evaporation of water (like how you'd feel cold when u step out of shower). Soak it and it's good for 5+ days. I use it for camping. Just keep it in the side pocket of your backpack or everything else inside will be wet. Always keep insulin, even spare, with you - thieves like targeting tourists.

Bring a card that says so in both English and local language. Know how to say you're diabetic/you need insulin in local language if possible. Know the local emergency number also. For cell phones 1-1-2 will redirect to the local number but it doesn't hurt to know the actual one.

Look into travel insurance.

If you're going far (think, Japan or US) - your first day is gonna be crappy from both jet lag and your unpredictable sugar during flight.

If you're going overseas, call up your pump and CGM manufacturer to see if they have a travel loaner program. Tandem sent me an extra pump for me as a backup when I went overseas and I wasn't charged for it since I sent it back within a week of my return date.

Have the travel letter with you. (https://www.medtronicdiabetes.com/sites/default/files/library/support/Airport%20Information%20Card.pdf)

See what you would need to do to get insulin, syringes, and a BG tester at your destination, just in case all of the supplies you bring with you disappears. At worst, you could live for a few days on MDI and a Walgreen's BG tester.

P.S. Here's a just-add-water insulin cooling solution that I used on a 3-week backpacking trip: https://smile.amazon.com/Insulin-Cooling-Reusable-Evaporative-Medication/dp/B0002262DA/

If she's only taking up to a month supply then she only needs documentation like a note from the doctor, Rx, etc.

If she's planning on bringing more than a month supply then she needs to get a "Yakkan Shoumei" which actually takes quite a bit of time (I've heard up to months).

If it has to be kept cool (below 80ºF) then you should look into a Frio Wallet. If it has to be cold like refrigerated then you'll need to look into ice packs and ice. http://www.amazon.com/FRIO-Insulin-Cooling-Wallet-Large/dp/B0002262DA

I got a frio wallet to keep my meds cool. All you need is water to activate it, so it's excellent for road trips, camping, and travel. It's never gotten too cold, and it lasts a long time.
