No actual figures but I ran my A/C & microwave quite a bit on our trip this summer and when we got home, the gauge still said full. I don't think the gauge is very accurate tho as when it was one light down from full, we could only get about a gallon in it. So the 36 hour estimate is probably pretty close.
