Question 1

Does this actually cool to 40 degrees or does it cool to 40 degrees below ambient temperature?  That is a huge difference it gets to 100 where I live!

Accepted Answer

I haven't tried it yet, but several reviews say it's 40 degrees below ambient. And that's one reason I'm probably going to return it unused.

Question 2

How long will it stay cold when not powered?

Accepted Answer

If powered long enough to get to its maximum temperature of 38F and turned off it will stay cool for approximately 24 hours.  By way of a couple of specific examples: (a) I’ve placed a bag of ice in this cooler when it was at its peak cool temp of 38F, turned the cooler in off, and had the ice stay frozen (without ANY liquid water forming) for 6-10 hours depending upon the outside temp, and (b) I’ve placed a bag

Question 3

Do you think this is a better cooler than the Coleman cooler for a truck driver? I'm looking at this one or the Igloo one.

Accepted Answer

Read my review of the Coleman Hot/Cold 40 Qt. Had a Coleman from 2000 that finally died due to a design flaw that allowed the fan to bind in the nacelle/ housing. Bought a new one that lasted 10 weeks. Finally got my refund 4 months later. Can't compare it to this one, but some of the other answers here are misleading. This product is not a portable refrigerator. Those have thermostats and use a compressor. Peltier devices are power hogs - about 5% efficient at transferring heat. So, 95% of the heat you feel on the exhaust of these is produced by the Peltier device, not from inside the cooler. Also, some heat is transferred through inefficient insulation. That's why it takes hours to remove heat from the interior of these coolers before you can start using them.

Question 4

6ft cord is not long enough to reach the back of my minivan, will cooler work properly with a dc cord extension?  Is it quiet enough to sleep next to?

Accepted Answer

I believe it should work with a DC cord extension.  We had the cool in our hotel rooms while traveling and had no problems with it being noisy.
