    Is this BS or real? ...
    yes, its real. I'm a bit surprised by how fast it corroded, but yea. Humidity/moisture will exacerbate the problem...

    ...hey, you're the one that started poking holes in your own testing methodology...

    lol...

    but I agree with your methods & testing... and question how their marketing and mags got their numbers... I wonder if they did more shock than they claim it replaces of ice... like maybe equal volumes?

    • Cooler shock will get the cooler colder than ice even when the start at the same, much lower than 32 degrees, temperature.
    • Cooler shock will not last nearly as long as ice. (with one interesting observation, see below)


    I didn't like the results of the 1st test, I had the sensors suspended in the air and neither ice/shock was able to chill the air. The lowest the temperature got was about 55 degrees for both cooling systems. (So the lesson here is that you food must be near the cold.)

    I didn't want to accept the second set of tests since it was just so against my belief in Cooler Shock shock that I needed to revisit the experiment. The cooler shock performed much worse than ice for longevity. I was still using the cheap red Igloo stackables shown above. You see, both coolers were really cold to the touch during the test. I'm not a thermo expert, but to me that seemed like it would skew the experiment.

    We had wanted new coolers for the upcoming camping trip so we got 2 of the Igloo BMX coolers. These are a poor man's Yeti. They probably have half the performance and at super low price. I think ours were $80 each for 55 quarts.

    I let the ice/shock chill over the weekend while we were away. On Monday morning I started the 3nd test. But something was odd. The shock wasn't as rock hard as I expected it and the ice bags weren't full! I added more ice, by weight, to get up to the desired weight. I started the test but abandoned it hours later when I got some popsicles out for a snack. They had thawed! (And yes, our fridge eventually failed, we don't have one right now and the new one is being delivered tomorrow!)

    I stopped the test because it didn't have a repeatable component. I didn't know, for certain, that the ice/shock had reached the 0 degrees that my freezer was set to. So I put them back in the freezer and waited a day and a half. (That was a mistake BTW, I really should have waited 48 hours.)

    Here are those results. Note, I've deliberately obfuscated the X-axis so you cannot draw any conclusions about the amount of time the shock/ice lasted. But you can tell that the ice last way longer than the shock, dramatically longer.



    I needed to run two more tests. One was to calibrate my sensors, did both sensors read the same? I also wanted a good time basis for the shock. So I froze the shock for 60 hours and ran the tests again, but I put both sensors in.



    Now a things really needs to be noted:


    1. Water is a great way to hold cold, air is not. But this is how cooler shock works, it chills the air, so this affect is real. I've seen tests that show that draining/not draining (while adding ice) is about the same. (When you drain, you drain cold away, but it also gives you the ability to add ice, which has the phase change benefit.)
    2. I ran the tests following the directions on the cooler shock packaging. 4lbs of cooler shock to 6lbs of ice. The cooler shock tests on their web site used equal weights. This is pretty realistic actually, ice takes up way more volume that shock and the test is a bit unfair that way. I suspect most people would use 1 shock per 1 bag of ice.
    3. Nobody has room in their freezer to store bags of ice for 48 hours. That's dumb. I don't know what the freezer at Market Basket is set to and I suspect if I installed my sensors I'd be escorted out the door before I could get a good reading.
    4. Ice sucks, it gets the food wet and throw a lot away. You must mitigate that somehow.


    So what are Susan and I going to do on our upcoming camping trip?

    Ice with food saver bags.
    Awesome! this is perfect. i will definitely be ding exactly that with the ice in the food saver bags!

    Oh yes, sorry if that wasn't clear above. Their marketing graphs used equal weights. They were not able to give me a good explanation why the instructions say 50% more. It seems odd. The instructions make their own product seem worse.

    Sorry to post this a week late . . . which might be TOO late, but I was trekking with my Jeep last weekend and am just now uploading the pics. The night before I left, I found this cooler at the Framingham REI. Originally $120 marked down to $39. They only had four left and were clearly trying to get them out of the store.

    It has great reviews on Amazon: http://a.co/d/dp1aheh and I can attest it kept my food nice and cold all weekend with a single YETI ice pack. Not sure if there are any left, but I figured I post up here in case anyone is in the market for a mini-cooler like this.

    You had Hummus and didn't share??

    Yeah - I figured that photo would earn me some hummus hazing. But Iíve learned from experience that cheese cubes, smoked almonds, olives, salami slices, hummus and a box of Triscuits is a trail lunch I could eat for a week straight . . . and not worry about getting crushed in the cargo. Next time Iíll bring extra for you!

    Default Cheap fridge instead of a cooler?

    I got sucked into looking at coolers but had another thought...

    I am not an overlander, having a 3 year old and another on the way, I'm probably a way off from any real camping experience. But, I do have a cabin and typically take an Igloo Playmate cooler. My wife mentioned that she wanted a bigger/better cooler so we could take more food up there. So, naturally, I decided to look at cheap fridges instead. My thought is that I'd like to see if a fridge is right for our use without investing a lot of money. On Amazon, I did a bunch of searching and ran across this Costway fridge. In the comments, one reviewer mentioned taking it on the Rubicon. Farther down, a reviewer mentioned taking it on Dusy Ershim. It has 4.5 out of 5 star review and mentions "normal using in 30* incline and bumpy environment". Plus, on the Costway website, it's $366... about what a nice cooler would cost. What do you guys think?

    I picked up a LIFETIME brand cooler @ walmart a few weeks back, for a long weekend trip Phyll & I took end of aug. Was a hot weekend. Kept the same ice the entire time. 4 days. Everything stayed cool. Ice left over. $65 for a 55qt. (On sale)

    Been thinking of getting a fridge over a cooler for years, as I think it is the way to go, especially after contaminating cooler water(thus everything) with raw foods leaking, soaking things that I didn't want soaked, and leaks inside cab. It was invaluable addition on the Time 2 Get Lost trip.

    This one is Chinese, so time will tell if they hold up :\
    Traction, articulation, and gearing make a good off-road rig. Just a big lift, wide mud tires, and a winch simply do not ;)

    The vacuum sealer really helps with the leaking problem, we used that for our recent 5 day trip and loved it.

    But yeah, a fridge would be great.
