Our fridge started to act erratically with troubling temperature fluctuations. While we waited to find out what was wrong, we needed to find something to store my husband’s diabetes medications and we needed it fast and it had to be reliable. I looked at scads of different options from mini-fridges, coolers, gels, you name it -I read about it. I was almost on the point of getting one of those dorm fridges (which I absolutely didn’t want, but what we were going to do for his meds?) when I saw a woman in a video holding what looked like a thermos. It seemed interesting so I watched. WELL – THIS WAS THE ANSWER TO MY PRAYERS.

This thing seems to be more for people who travel and need something to keep their meds at the right temperatures. One way to use it is with Biogel that you freeze and then insert into the thermos. But the part that interested me is that it plugs into a power source and maintains temperatures of 36°-46°F. It can be affected by ambient temps – so this is something to be aware of. It does have its space limitations inside, but for us it is a godsend.

Basically the outer part is a thermos. The screw on cap, which has a place to insert a USB wire and then plug into an outlet is the power source. The cap has a long open ended tube which is where the cooling is and it is into this tube that the meds are stored. I was able to fit 4 Levemir (that’s all we had at the time) inside the tube. Or I could have put in 2 Trulicity. Be aware that it will not fit more than 2 Trulicity (one up and one down) because of the ridiculously large base of their pen. I actually called Lilly medical and asked them to rethink their design - it’s too big.

So, although the fridge is semi-working again, (now the temps are too cold and no amount of adjusting seems to make it warmer, but according to the repair people, there’s nothing wrong with the fridge. What?) we’re essentially using it full time. It’s a teeny weeny, itsy bitsy mini refrigerator and so far it’s working beautifully. It doesn’t require much room, is extremely quiet, shows the temp right at the top for easy monitoring and although I have it on a table in my living room, it is not in any way an eyesore. If you weren’t looking for it, you’d probably not notice it.

If I have any complaints it’s that it’s kind of expensive and it isn’t big enough inside. But I actually got to speak to the VP of the company and asked him about making something bigger that isn’t necessarily portable. I’m sure we’re not the only ones to have a fridge conk out with no place to store insulin or other meds needing refrigeration. He said that it takes research and time to get it right and who could fault them for wanting to do it right - not fast. Hopefully they'll work on something. Because I have to say that I feel very confident about the quality of this product.

So, I’ll tell you how much I love this little thing – I named it. They call it Voyager which made me think of space which made me think of Star Trek which made me think of an especially iconic character. So we’re calling it CAPTAIN KIRK because really, this too is one of a kind.

I take medication that requires refrigeration. I travel a lot, often on a plane for 9 hours, plus additional land travel. This cooler holds my medication at temperature very reliably. Buy two power packs if you are on the road more than 5 hours. As far as portability, the cooler is not overly heavy, but it is somewhat awkward to carry. First, the cooler can slip out of the “pocket” type carrying case. It needs something to keep the cooler in that pocket from falling out. Second, the strap needs a redesign, so that the cooler doesn’t “tip” as it is being worn on the shoulder or across the body. However, the cooler is reliable and does a reliable job. I can fit several vials of medication plus syringes in it. I have a friend I recommended this cooler to, and she fits several injectable pens in hers.

This top paragraph is an update after 2.5 years of ownership. I use this unit for travel, so I do not use it constantly. After 2.5 years of use the fan is starting to fail. This is not unexpected, small fans like this unit has inside cannot last forever. This unit requires the fan to move enough air to cool the hot parts of the unit. When the fan fails, the hot parts heat the entire unit! It heats to about 97 degrees according to the temperature readout of the unit. This is actually the expected failure mode. Essentially the heat pump in the unit is still working, but it needs the fan running to work correctly. I would like to ask the manufacturer to do something to address this issue. The fan is easy to replace, I would suggest that the unit be redesigned to make it easier to open, and that replacement fans be made available. Also the unit should have a mutable alarm for temperatures above ambient. It it is starting to act like a heater, the user should be warned. This is still a positive review, I still like the unit, I simply have experienced the end of life of the fan. I will replace the fan, and it should work like new. If you think "this is bad because the fan can die", all medication chillers that run on electricity will have a fan of some sort, and fans can fail. Small fans cannot be made to run forever. They clog with dust, and the bearings wear out. They should be replaced every couple years. Your PC has small fans in it, it will start acting bad when one dies, it is a $10 part, but some people replace the whole pc because they don't know any better. There is another reviewer that charted the temperature performance but he gave it low marks because of the failure modes such as loss of power could result in lost medicine.... And to his post I would have to agree, as it dovetails into my failure mode from the fan. The seller should add a second model to their lineup that includes wifi/blutooth with a cloud app and notification service that can alert caregivers and the user's phone. This will add around $10 in hardware costs, though it may be lower if they simply delete the existing chips and start with a wifi imbedded cpu. The upgrade will require software and will add $100 worth of value, so it can be the higher-end model. I could write a book on the features it needs...-

In 15 minutes, I was able to cool the unit from a reading of 87°f to 36°f using the supplied cable and charger, in a room that was 74°f. I see a lot of complaints that are related to improper use. If you are having problems, read and understand this whole review. This unit does work, and it's limitations are in the instructions, but it may take an engineer to understand the limitations and explain them properly.

I am an electrical engineer. And I happen to have very specific knowledge about how this unit operates, and why some people have issues with it. This is a 10 watt rated peltier junction refrigeration device. As long as the fan works, this unit will be functional as the solid state nature of the cooling device should have it last a lifetime. But for it to work for you, you will need to understand how to power this unit. This unit has a short USB C cable, and requires a power supply that can handle 5v at 2 amps to supply the rated power of 10 watts. If you don't use the power supply that came with it, you may have trouble finding USB ports that put out enough power. The standard USB2 port can only put out 1/4th the power this unit is rated to use. If you plug it into a standard USB port, the unit may only provide a tiny amount of cooling, and it may not be enough if it is in a warm location.

This unit draws 1.5A of power when it is cooling, and if your power supply can't put that much power out, the cooler may not have enough power to do the job.

This is important to understand... This unit can provide a maximum of 50° of cooling. That means if you want it to never get above 47° it must never be stored above 97° with insulin inside... If you put it in the trunk of the car on a 110° day in the Texas sun, the inside of the trunk may get as hot as 150°. at that temperature the coolest your medicine will be is 100°. On a hot dashboard where I have measured temperatures of 170°, you can expect internal temperatures no cooler than 120°. The 50° cooling this unit provides is a real limit, so plan accordingly.

This is a reliable device, but power cords are frequently mistreated, so buy extras, and don't buy the cheapest cord you can get. To provide the 2 amps of power, you need a proper thick usb A to C cable that is capable of carrying power, so look for cables labeled "quick charging" to insure they are designed to carry the rated power. If you want a long cable, it must be thicker, so get one rated for 100 watts or more (for best results). The longer the cable, the less cooling you will get, so even though this is a 10 watt device, the reduced voltage drop from a 100 watt cable will provide help you get the maximum cooling.

And if you use a power bank, be aware you will be drawing 8 watts when it is cooling, and in a warm location that drain will be continuous. Most power banks are rated at a higher wattage than they actually support, so it is best to assume the power bank will only put out 25% of the claimed power, but it could be as much as 75% from a high quality brand, but most you see on amazon are going to be closer to the 25% range. This unit draws 1.5Amps, that is 1500 miliamps. So to run this unit for 24 hours in a warm location, it wants 1500 miliamp hours of power per hour, so 36,000 mah per day. a 30,000 mah power bank *should* run this for exactly 20 hours, but in my experience you can expect 5 hours from cheap power banks, and perhaps 15 hours for a good power bank rated 30,000mah. The reasons the ratings don't provide real-world results is the batteries are 3.7v rather than 5v, so power is reduced by stepping the voltage up to 5v, and it is further reduced because 95% of the batteries from china do not actually hold the amount of power they claim, so the rating of the power bank will be off by however big the lie was when they sourced their batteries.

And finally, this unit turns off cooling at 36° and turns it back on at 46°, so the temperature will cycle across that range. I use two insulin and one liraglutide products. The strorage instructions are long term storage in the 34-45°f range, and storage BELOW 80°f for up to 30 days after first use. I have changed brands several times, these temperature ranges are common to all of the insulin/diabetes injectables I have used. so if you are carrying a 2 week supply, for 2 weeks, then 79°f is a target temperture to stay under (you guys that think you must have insulin be refrigerated all the times are either wrong, or you are using a cheap and unstable form of insulin. The point is I read a lot of reviews of people that claim cooling requirements that may not be actually true. Read the whole label on your injectables, not just the part that says keep refrigerated. Mine say below 80 for up to a month. Most of yours will too. The important thing here is this means that the maximum powered storage temperture for a 2 week supply is 79°f, which with the 50°f cooling capacity means your medications can be kept safe up to around 120°f if fully powered and out of direct sunlight. Direct sunlight will add heat.

The biogel will work at higher temperatures, but the hotter the shorter it lasts. If you are packing without power, I would generally trust the ratings of the biogel, as that is a reliable source of cooling. If you travel by plane, be aware that the biogel must be frozen to get past security. If it is melted, you will not be allowed to have it in carry on luggage, and they will make you throw it away. So using the biogel for air travel requires you to have it fully frozen in security, or you will need to pack it in checked luggage. But if your luggage is lost, all bets are off as to the condition of your medications, as they might spend a week in a metal box in the sun at an airport, so a reason TO and a reason NOT TO store in checked luggage. Decisions decisions. Buy two coolers and store half of your supply in checked luggage and half in carry on.

So to recap:

- provide power from a "fast charge" capable power supply

- Provide at least 10 watts of power on a good cable

- Do not store it at temperatures exceeding 50°f of the desired medicine temperature when powered

- Cools quickly when empty, probably needs an hour or so if full (unless you prechill as recommended)

- If you are having problems call the number on the door hanger

- The warmer it is, the longer this will take to cool down (reality is harsh)

- Test your power supply and know your limits

- Cars can get really hot, 75°f higher than the temperature outside is easily possible, so this cooler can't do it's job in a hot car for long

- The temperature of the display is that of the cooling device, you will see it cycle up and down from 36° to 46°, but the ACTUAL temperature of your meds will be the higher of the temperatures you see it cycling between.

I did several tests using the provided charger, and the unit works GREAT. It performs up to the claimed capabilities. It cannot do the impossible... nothing can. I paid $200 for this, I think the value justifies the price. There are plenty of biogel based coolers for 1/8th the price, I still think the value justifies the cost of this unit. I'm an engineer, I could make one of these for under $50, with about $1000 worth of labor. Buying one already made is a good value.

This cooler is great, it kept my medications cool for a long flight. It was a bit cumbersome to carry, but still serviceable. HOWEVER, the plastic clips on the shoulder strap are not secure. On my first trip with it, i bumped it with another bag as I was getting out of the car. The plastic clip opened up and dropped the cooler onto the pavement. The cooler top cracked and fell off. Fortunately, the cables stayed connected and I was able to hold the cap on and the cooler continued to work. Then the strap release again while getting off the plane and one of the cables in the lid came loose this time and the cooler stopped working. The cooler stayed cold enough during the trip from the airport so the medication was not damaged. Once at destination, I was able to figure out how to reconnect the loose cable and the cooler works again.

I also purchased the recommended battery to keep cooler operating for hours. I think the extra weight of the battery contributed to the failure of the plastic clip. I have a service request in with the company to see what they will do to help after the clip failure. I will update with results.

I have now ordered a new, more secure shoulder strap with metal clips so the plastic clip does not fail me again.

I have to take growth factor injections for my cancer and they need to be refrigerated. I was initially freaking out because I wasn’t sure how I’d leave the house and keep so many at that temperature. I thought I might need to get a cooler and use ice or dry ice, or something along those lines. Amazingly, after a lengthy Amazon search, I came across this invention.

It is basically the size of a regular thermos. The instructions inside and online mainly talk about the diabetes use case as I think some forms of insulin also need to be refrigerated, but they should add that this worked great for growth factor meds as well for cancer. Specifically, in case anyone else is wondering if their medicine will fit, I have used this for Zarxio and Neulasta. Both are about the same size.

For both, I had to remove the syringes from their packaging (plastic tip covering the needle stayed intact!), but I made sure to add some cushioning (balled up paper towel) at the top and bottom of the container to make sure they didn’t move. I believe I was able to fit 4 of both medicines. I might’ve been able to fit even more if I added some vertically in the container, but I haven’t needed to yet so TBD on that.

I bought the max capacity Anker power bank allowed by the TSA and also a right-angle USB C - USB cable. The power bank provides about 10 hours of charge. The cable provided seemed a little weak and the right-angle of the new cable reduced any chance of the cable getting disengaged or something.

Once the power bank is turned on and the cable is plugged into the container, there is a fan on top that starts and a temperature reading on the display. The temperature display is honestly what I love the MOST.

Prior to my purchase, I had a moment in a hotel where I was pretty sure the mini fridge was not within the acceptable range; the drinks were not cold - just not lukewarm. The hotel also did not want to store my medicine in their kitchen fridges for fear of liability. During a few desperate hours, I even went searching for the mini fridge’s manual to see what range it operated at and how I could turn the temp to the lowest. I ended up pulling out all the bottles to attempt to ensure my medicine would get chilled, but I couldn’t guarantee the actual temp. It turns out that most mini fridges aren’t even cold enough to safely refrigerate your leftovers, so how can you trust them with your medicines then…

With this product, I can always tell what the temp is. My main thing is making sure I have enough power in my power bank, so whenever I can stop and use AC power and charge the bank, I do so. When I get to my destination, I immediately switch to AC power, too. Obviously if I’m at a location with a real residential fridge, I’ll transfer to that.

I do get a little worried about the motor overloading so once a day I’ll unplug everything, give it a rest, then plug back in.

I have not had any resistance from TSA or airport security overseas. Sometimes I get asked, but once I let them know there is medicine inside, it’s not a problem. Most agents, actually, have been quite awed by the device and ask where I got it.

What could be better: the sling and the plastic clip are a bit cheaply made. I was looking at Stanley cup-type slings to see if that would be better, but haven’t bought one to try yet. I would just suggest the company to consider a metal clip for peace of mind, at the very least. The blue holder could be aesthetically improved, but it works fine and that’s what matters first.

Another idea if it could be possible: if there was a way to be notified if the temperature suddenly drops or the device turns off on its own. Analog could be some kind of noise, digital could be Bluetooth-based simple alert. I am always checking for the the display when I’m moving around just because if the power cable gets dislodged or the bank runs out, the device just goes silent.

Thank you to the company for making a reliable product that frees up folks from carrying around giant coolers and refrigerators. In the midst of illness and all its obstacles, this simple freedom goes a long way.

The refrigeration piece is pointless. I cannot keep one genotropin pen in the canister - it will not shut. The gel pack is good and I could fit one genotropin pen and a hormone refill. This was a huge disappointment as I was expecting to refrigerate this hormone in my hotel room. I ended up having to store the gel pack and hormones in the hotel’s kitchen - the exact situation I was wanting to avoid. I would appreciate if someone could demonstrate how they get multiple pens in the canister with the refrigeration top in place- then maybe I will keep it.

I purchased this product for my husband who travels long distances frequently. He uses Orencia prefilled syringes (not the auto injector) and this fits 2 comfortably. He has not had any issues with the cooler. However, the power cord needed to be replaced. Though not planned, he has had it continuously running for up to a week without issue. He has purchased a different holder as he felt the one provided was a bit flimsy. The cooler has provided peace of mind and is well worth the money. He hasn't experienced any issues with TSA, customs, or airlines.

Keeping my insulin at the right temperature has always been a struggle when taking long trips. Usually, after a trip, I would discard the unused insulin because when it warms up, it loses its efficacy. I've tried cooling cases which require ice packs, but the ice usually melts before I get to my destination. I purchased the 4AllFamily Medicine cooler not expecting that it would actually work. I used it for the first time when I took a trip from Washington DC to Hawaii. That is a twelve hour flight! I've taken this trip, many times in the past, and the ice always melts. On several occasions, I have had to purchase replacement insulin because I had lost confidence in the efficacy of the insulin. The 4AllFamily medicine coller worked very well. It's small but very effective and it keeps the insulin between 36 and 46 degrees. On my last trip to Hawaii, the insulin stayed effective and I was happy to have found a solution to the problem. On a recent trip to the Caribbean, the top of the unit detached from the base and the power cord between the battery and the unit was broken. I called the customer support line and the company promised to send a full replacement. I should have the new unit, by Monday. This is a great product, and I was very encouraged that the company was responsive and agreed to replace the unit. I would suggest a couple of design changes, however. First, the top of the unit, containing the electronics, needs to be better secured to the body of the unit. The power cord from the battery sticks out of the top of the unit making it easy for it to break and destroy the USB plug. It would be a good idea to recess the the USB receptacle so the plug doesn't break off. The final suggestion concerns the carrying straps. They way they are designed throws off the balance of the unit when carrying it. These are minor improvements which will make the unit more resilient and better protected from the bumps and grin ds experienced in an airport and on a plane. I should also mention that I never had a problem with TSA. They never asked to have me open the unit nor did they delay my security check because of the unit. If you are concerned about keeping your insulin at the right temperature on a long trip, especially to a sub-tropical climate, this cooling device works very well and the battery pack is essential.

Display on the USB top says 39 but when I use my digital thermometer it gives me readings in the low 50ies. Not low enough for GLP1 storage. Unfortunately I didn't test it before the return window closed. Now I have a 30 hour international trip in 5 days and I'm scrambling to find another solution.

Comprato per un amico diabetico, ha sua detto è un accessorio fondamentale e super comodo!

Product works great for flights with one minor adjustment. I Used for a 21 day travel abroad from BC Canada to Ireland then Scotland. Flight was Van to Amsterdam then smaller airline to Ireland so not needed to transfer to Scotland. I use Trezspire for Asthma via epi pen one dose every 28 day. My dose was required mid trip. It worked great and maintained required temp well, we did group tours lots and stayed at hotels for 1-2 days only so lots of on and off buses and kept it on my outside bottle holder of backpack. Stayed at high end hotels not all hotels had a fridge so unit needed to run those days, longest run time was 4 day. ****NOTE- many airlines will not allow you to use usb system with power bank or their plug ins during taxi, take off and landings***** My USB lid has an attached tube so not able to use bio gel and switch lids. Many airlines won’t let or can’t put it in fridge (some smaller airlines use dry ice and risk of freezing is high). I recommend and will do for myself

Next time is to order the rambler with biogel and use these during the temporary times I am

Not permitted to use the USB capability. For those who have the units without the internal tube I believe you can use the bio gel combined with the USB LID and switch the lids during restriction times. Will certainly use again and recommend it was the best way to travel long duration and ensure consistent temperature

I bought the Voyageur with the USB cooler in July 2023. It was working fine for a couple of months as I used it sporadically in my travels. I try and use the gel pack mostly and the USB cooler only if I am in a place where there is no access to a refrigerator. While it was in use, recently, the USB cooler suddenly stopped working, the display was at a constant 99 degrees. I wrote to the customer service and in a matter of a few days, after some exchange of mails / videos to understand the exact nature of the issue and what mitigations could be possible, Peter arranged for a replacement at no cost to me. I must say the product is good no doubt, but their customer service is what makes it worthwhile to deal with this supplier. I hope my USB cooler will work without issues - only time will tell, as I am about to embark on a tour where the USB cooler will be very important for me.

I am so glad I bought this. It is expensive but worth every cent.

I have previously been on holidays in South East Asia where my insulin has got hot and I ended up triple dosing etc and ran out and had to source some overseas.

This product works perfectly. Sometimes you may not have access to a fridge or if you do it doesn't work very well. The attached fridge works really well and fast.

I ran the fridge for several hours on a train using just a power bank.

Using the icepack will keep things cold for a while day easily.

It was great having the flexibility between fridge and icepack.

Product was a lifesaver.
