Talking 12 volt cooling system question

Not sure if this is the spot to post this question, but my SO and I are planning a four corner trip in August. Me all the way, SO just West to East. Both of us have medical needs that need to be kept cool. Diabetic stuff.
here is the question. does anyone know of a cooling, refridge unit that could be used on the LT. and not take up a lot space

Glad you're living your life! Congrats!

Any "12-volt" based system will work.. LT is standard "negative ground" bike so wiring in will be "simple".

My Mom travels with her "car fridge" plugged in... does a decent job.... even for several days....she could go longer, but doesn't.

Unfortunately, the little 12 volt "thermoelectric" coolers will not cool much less than 30 degrees below ambient. That means that if it is 90 degrees, the inside of the cooler will be about 60. I had one mounted on my LT for my 10/10ths trip, it worked pretty well as long as the temps were around 65, but as the temps got up around 85 it got pretty warm in the cooler. They use Peltier Effect modules, and do a fair job until it gets too hot, then they struggle. Use 3-4 amps too, so don't walk away from the bike with it plugged in for any length of time.

I looked at a small 12 volt cooler once that had a "swing compressor", and used refrigerant, but it cost far too much, around $300 if I remember correctly.

I don't want to achieve immortality through my work...I want to achieve it through not dying.

Not sure this will work but it sounds better than most. At least it's something to check out.

We have this one at work in one of our trucks and this one works really good but it is quite heavy but maybe you could call the company to see if they make a smaller one.

Took me a minute to find this, it's funny I JUST read about this this morning. What a coincidence.
I hope this will do what you're looking for, you will need to connect a voltage converter to drop the voltage to 5v and all that, but it should be pretty straight forward.

That one uses ice and water! Don't think it will fit the bill. If one already has the ice, don't need another cooler.

That one probably has a swing compressor in it. Even more expensive than the one I found a couple years ago.

Keep it Simple

Maybe a small ice chest would fit the bill just as well.. A little Ice goes a long way.......and it's cheap...No Current draw on the battery.. Lasts for days on a single "charge"....

Zero volt cooling system

Willing to give up your left side case?
I have used the left side case as a cooler, buying bags of ice at convience stores and tossing them in the side case. Buy ice at fuel stops.
The whole side case becomes a cooler.
Quick, easy, cheap.

You could always try to use dry ice instead of regular ice. Done right it lasts a long time.

What I have is a small zippered pack that is made for diabetic supplies that has two pockets with removable freezer gel packs. Unless you are planning on doing a lot of camping placing them in a hotel/motel freezer each night on the road will keep your insulin well below room temp. All the insulins that I use can be kept at room temp for up to 30 days after being opened. Of course check with your diabetic professional before doing this. My zippered kit is made by Atwater Cary Ltd; these can be found listed in most diabetic magazines.

Toby, we have the same problems. Both my wife and son are insulin dependent. My wife and I have rode all over the USA and no problems. We put the insulin in a small thermos bottle like soup would go in and the meter is in the saddlebag. Sometimes the meter whould show "hot" but we usually stop in somewhere for a bite to eat or drink and let it set on the table for a few minutes and it will cool off. We also live in South Texas so we deal with the hot for a long time.
