Product review (4 stars): Better than original Whynter cord!
The original cord was shorter than the AC cord.  This made it a bit less convenient to find places to put it in the car. So when I had to replace the original cord (It had the tip of the plug broken off) I looked for a replacement.  I saw this, and while rather expensive I decided to order it.  The new cord is a heavier gauge wire than the original, which is a good safety feature that keeps the wire from overheating and also wastes less of our battery from resistance.  It is MUCH easier to find a good place to put the cooler when you have ten feet of cord!  The only small minus is that unlike the old cord that has a straight plug, this has a 90 degree right angle.  So even if the 12v port is on the left you still have it going off to the right before you bend it over.  On a short cord this would make it harder to reach the port if it's on the wrong side.  But with this much length it just looks a bit funny...

So, while I wish it wasn't so expensive I think it's worth it.  I wish Whynter had an option of buying the cooler with it instead of the short cord!
