I'll let you know my test results next weekend. I just ordered one from FL off of Amazon for <$40 and expect to get it by this Friday.
I was curious to see how well this works compared to my tests so far of
1) just using the cooler (external temp zapped with IR thermometer 60F)
2) cooler wrapped by small camping blanket on top/front/left/right (55F)
3) same as #2 but with addition of sofa pillows stacked around blanket on all sides + 1 more around the back side too (43F)
4) for giggles I put it back in the shipping box and cut out sections for the air intake/fan exhaust and power cord area to see if the box could be used as a poor man's transit case with the only insulation being the top and bottom styrofoam shipping materials (49F measure the top cover only as I was too lazy to lift it up along with the contents in the cooler to zap the sides with the IR thermometer) I suppose I could go to the hardware store and get some insulation foam pieces for the front/sides/back but too lazy to consider that step yet
Can you tell I"ve got too much time on my hands playing with this new camping accessory?
testing done. don't bother wasting money on the transit bag. I just posted my review on amazon for the bag that I got 2 weekends ago:Has anyone bought one of the insulating covers for their fridge? I am considering one as we live in Texas and Travel out west mostly. I don't want to spend the crazy money they ask for them if they do not work well to insulate. Thanks for any input. Joel
"I purchased this initially in the hope that it would provide some insulation benefits and reduce battery consumption while traveling in the truck or out camping. After testing for 1 week with this case and various other forms of insulation around the cooler it appears that there is zero benefit no matter what the insulation around the cooler is because of the design of the cooler itself. Heat gain introduced into the refrigerated compartment when powered off is the same because of the venting area underneath the non-refrigerated compartment.
Does it provide any insulation benefits? Yes, measuring the external surfaces with an IR thermometer shows that the exterior is actually 4-5 degrees cooler than without the transit bag on a cooler. Unfortunately due to the poor fridge design, it doesn't provide any benefit for the compressor running any less so the only real benefit of using this bag is to provide some exterior protection to your cooler from other things that might be around it.
0 stars for insulation
4 stars for cooler protection, 1 star deducted for design of the lid - this bag would have been better if the top was a separate piece that also included some velcro strips so that it could be attached to the cooler lid instead of other parts of the transit bag so it wouldn't be such a hassle to deal with adjusting 8 pieces of velcro when opening/closing the lid all the time."
