Question: Is it tall enough for milk gallons or 2 liter bottles to stand upright?
Document: I purchased this cooler along with the 120 Volt Adapter. Placed a few bottles and a jug of water (just luke warm) into the cooler and after 2 hrs had the water in all containers cool. After 3 hrs cold, after 6 hrs very cold, after 10 hrs a bit of ice was forming on the top of a the smaller containers. It cools slow as Colman states in the manuel, and drops the temp 40 below ambient temp.
Bought it for my parents and it quit working the 3rd time they used it. It was great the first 2 times though...
It works great. I keeps the cooler temperature about 30 degrees cooler than the room temperature. It's great. Has milk, orange juice, Coke, Ensure. In the old days, in Savannah, I had beer.
We use this in a small teardrop trailer and it works really well so far. A great test is that I drink Milk and have yet to have a gallon spoil over the week or more that we kept it in our Coleman. I am having a wire installed in our car that will allow us to keep this running while hitched and enroute.
I am an over the road truck driver and used one of these every single day for 2 years. the only problem is that I have ever had is occasionally it needs to be cleaned out and dehumidified. one of the small fans went out inside of it eventually and I gave it to a friend who repaired it is still using it.
I purchased this cooler couple of months ago, This is not a refrigerator, It does deliver 40 degrees cooler than the outside temperature, used for camping twice, As long as your vehicle engine is running, it would do the job, Really like the convenience of not carrying any ice. If you have little kids , perfect to keep that milk cold.
This unit was purchased to be used in a semi. It lasted maybe two months before the end of the cord going into the unit simply melted. It may be great for picnics or camping and such but not for extended periods of time. That set aside, the unit performed great while it worked. It kept things so cold that milk was kept near the cooling unit and salads were kept farthest away.
I am on my 3rd one in less than 3 months  The first one ran for almost 3 weeks & quit working. The second one ran for almost 5 weeks & quit. On my 3rd one & it's going back today. It's like a deep freeze. All my drinks are freezing & bursting. Nothing like having 2 cans of coke freezing & bursting & spraying all over the inside.
I was very excited when I got this. It worked great when we took a road trip from Oregon to Disneyland. Then the next time I used it, it lasted about 5 days and then started making weird motor noises. I unplugged it thinking maybe it was just overheated. Plugged it back in and it worked fine for a couple more days, then it just died. I spent $90+ for about 2 weeks of usage. Wasted my money. I am pretty disappointed.
I plugged it in Saturday morning (I also bought the power brick) and let it rum. Since I was not sure if it would really get cold I placed a thermometer inside so I could check. The temperature in the living room was about 74 degrees. By Sunday evening the cooler registered at 30 degrees.I packed the cooler with soda cans and water bottles  chilled in the refrigerator.
Answer: Yes 2 gallons standing and I put 4 lbs of ice just in case, but the ice did not melt
