Outdoor activities during the summertime involve some creative ways and gadgets to keep our liquid insulins cool while away from a fridge.
In this trail-test, I take the 72 hour insulin cooler out on a number of expeditions to see where this product shines and where it doesn't.
This is the 72 Hour Insulin Cooler
by 4 All Family
It’s made from 304 Stainless Steel
It’s dimensions are 8.3cm (3.3″) diameter and an internal volume of 900 ML (30 oz)
Its lightest weight (empty) is 387 g (13.5 oz)
Kind of like a vacuum thermos flask, with an additional USB powered lid that makes this into a small mini-fridge
for storing insulin at temperatures between 2º C – 26º C (36º F – 80º F).

Can be used as a “powered” cooler with the USB lid, or un-powered by using the cold pack Bio-Gel that you pre-freeze in the freezer.
For this review, I went on a number of expeditions and brought the 72hr insulin cooler into a variety of environments where the outside temperature and exposure would be an issue for heat sensitive medications like insulin.
For many outdoors activities, it works really well.
I have listed some activities below, testing the capabilities of the insulin cooler.
Here’s what I found:

The company (4AllFamily) provided me with this product free of charge in exchange for this blog post as an affiliate promotion.
Beach Day
Here’s where the 72hr Insulin cooler really shines.
The beach is one place sure to get a lot of sun, so to protect your precious insulin from baking in the heat, under direct sunlight, it’s nice to have this temperature-controlled vessel to store the insulins in.
Wether keeping just a vial and a syringe, or a collections of pens and needles, there’s even room for glucagon.
This is one cool place to store the medicines.
Using the freezer gel and the standard lid, there's room to keep things cool for a few hours at the beach.
With or without the freezer bio gel, the USB powered lid can create a portable mini fridge.
Long Road Trips
Another place this cooler works really well is on long road trips.
Depending on space and length of the USB cable, it can travel under the seat, in the back seat, in a cup holder or on the floor.
With USB power:
- With the USB powered lid, there’s no need to bring the freezer bio gel.
- There’s usually USB power available in most cars.
Without USB power:
- If there’s no USB power, then the freezer bio gel will have to travel along.
- Bio gel can keep the contents of the cooler cold for a couple days.
- Refreeze the bio gel at the next motel, or the destination
This one in a Prius barely fits.
At The Crag
For a few of us outdoorsy diabetics, we really love to climb.
Outdoor rock climbing areas are rugged, remote, and often exposed to the elements and unprotected from the sun.
The stainless steel case is durable enough to bounce around with my climbing gear in the backpack, although I did get the blue metallic finish a little scratched up while shooting on this climb day at my local crag.
Desert Camping
Here's another place where this product really comes in handy.
It can get really hot in the daytime here in the Mojave Desert, and knowing theres a safe place to keep my insulin cool and protected from the heat and the sun in harsh environments like these, I can relax and enjoy this magical landscape.
Desert Treks
🌵
Adventures in the desert!
To continue our desert adventure away from the campsite, we often venture out into the desert with off-road vehicles and spend the days exploring geological sites, scrambling around majestic rock formations, and discovering hidden desert oasis'.
Our desert day supplies need to come along for the ride, including any medications the explorers might need along the way.
Here's where a solar charger is really handy.
Day Hikes
Here's where the 72hr insulin cooler takes a break from the outdoors activity, and makes better use of its capabilities back at base camp.
While the cooler is just too big and heavy to carry along in small day packs, we will need to pair down to a smaller, lighter insulin carrying vessel.
Leaving Insulin at the Trailhead
Leaving my critical backup insulin in the car at the trailhead is a good safe practice, especially for hikes that are planned for only a few hours out, HOWEVER... there needs to be a way to protect the insulin from the heat.
The bio gel pack will keep backup insulin safe and cool inside the car for a couple days if the container remains closed tight and unopened, no matter how hot the car gets on the inside.
It's a common practice for me to leave backup supplies at the car when I'm out on a day-long adventure in the mountains, and just as important is to make sure my supplies are temperature controlled.
I usually bring only fast acting along with me on a day hike. Insulins like Afrezza are perfect for day hikes because they don't need to be refrigerated.
When I was using a pump, my insulin would be traveling with me, but in case of a pump fail during the hike, I'd need a backup vial and syringe waiting for me at the trailhead for when I return.
Group Outings
With group expeditions there are often opportunities to share some of the load especially with communal items that everyone will be sharing.
In Type One Outdoors group outings, there may be a unique opportunity for one T1D hiker to carry all the insulin of all the other T1D's in the party,
and keep it all cool and protected for the length of the outing.
for a day hike.
Backpacking
Here's where I need to make critical choices and compromises in regards to size and weight.
I normally carry 2 pens (and needles) in a cooling pouch which is: ~150 g (!5.25 oz)
and my quick acting Afrezza in a cooling wallet which is: ~280 g (~10 oz)
Jumping up to the larger metal insulin cooler puts my insulin weight to: ~820g (~1 lb 13oz)
An increase of ~670 g (~1.5 lbs)
•Long-acting Tresiba
•Med-acting Humalog
•Fast-acting Afrezza
This weight / volume compromise is the factor that may (pardon the pun) "break the hikers back"
when deciding which insulin cooling method to carry along a backpacking expedition.
If it's a personal / solo expedition, I'll have to go with the lighter / Cooling Pouch option.
However, when backpacking with a group, there's always the opportunity to share the load .🤠
for an over-nighter
Notes
Pros
The functionality of the insulin cooler is what makes this work well in hot, environments.
- Keeps insulin cool. (much colder than a pouch)
(see lab temperature results below)
- Durable in rough, outdoor places.
- Can fit in most carry-along scenarios.
- Protects medicine from light.
- Can hold a multitude of insulins including vials, pens, pumps, pills, glucagon, Afrezza, etc. along with other temperature-sensitive medications.
Cons
It really comes down to personal preferences here.
- Weight
Can become an issue when pairing down weight for carrying in a pack.
Its lightest (empty) weight is 387g (13.5 oz)
Its heaviest (full) weight is 950g (about 2lbs) - Size (volume)
Can be an issue when space is very limited.
Its outside volume is ~ 1,212 cm³ or 1.21 l. (74 in³) - Tech
The only tech part is the USB lid.
It’s really a personal thing of mine, and I try to avoid bringing extra tech into the backcountry due to the risk of failure. But even if the USB lid fails, the contents will stay cool if the smaller metal lid is used with the freezer gel..

Temperature Tests
How many pens can it carry?
(these quantities are assuming pens only, no additional freezer gel pack)
In my own test, I managed to squeeze 6 pens:
(including the freezer gel pack)
1 Lantus Pen
1 Humalog Pen
1 NovoRapid Pen
And still room for pen needles, a vial or two, and syringes.
Vials and Cartridges?
Vials and pen cartridges only (no pens) allowing room for the freezer gel pack.

What capacity power bank do I need? 20000mAH?
Yes, a 20,000mAh will work.
I’ve been using an old 3350mAH pack and it will run the motor for about 5hrs before it needs a recharge, but it’s old.
