Question: does this machine big enough for gallon milk jug
Document: Bought this for an extended road trip...LOVE IT...We bought an AC adapter as well so we could take it into the hotel at night. Cools VERY well and holds temperature for a long time. Big enough for a gallon of milk and other things too.
I'm glad I got the bigger size. We have a weekend place about an hour away. If I bring food back/forth, I usually do a small cooler. This weekend I used this cooler instead. It was perfect. I was surprised to fit 1 gallon of milk, a jug of OJ, a package of steaks, a regular sized sour cream, 2 bags of grated cheese and a can of biscuits (plus 2 vials of insulin).
Always keep it in my car. Great for impulse shopping or for cold drinks on the road. Using it has become a habit with us. And, liter sodas or half-gallon milk jugs stand upright. No need  to rush home after grocery shopping.
I have used this on two trips, one 800 miles and one over 3000. I pre-cooled it overnight and filled it with cold items such as a half-gallon of milk, vegies, yoghurt, etc. I like the way the fan is protected from being crowded and thus overheating. It had ample room for our needs. It is easy to carry, and to plug in in the vehicle and in motel rooms.
So far so good! Used it on a couple of 4-5 hour trips so far. Pre- chilled cooler then put items in cold and they stayed cold the whole trip. Actually fit a whole gallon of milk and a 1/2 gallon of juice with room for a bunch of smaller things up top(yogurts and a few bottles of water)  Surprised by that! I also bought the adapter plug to use when we arrived at our destination to keep it cool for the next days trip.
We wanted a smaller 12v unit for lunches on a road trip. This unit was big enough for our drinks, and everything we needed for lunch and easy to carry to the picnic table. We used it on a one month road trip. It cooled well with no need for ice and so far, no problems. We put a couple of small gel packs in to help hold the cold during short stops.
We are big campers. It's the perfect size for cans which can stack two high. We are very pleased with it!
My husband and I are over-the-road truck drivers. We keep this cooler in the top bunk which is the hottest part of the truck yet it still does a great job of keeping things cool. The size is perfect for 1/2 gallon cartons or cans of pop stacked two high. My only gripe is a design flaw which does not protect the fan.
I bought the AC-15 Adapter to go with the Koolatron Compact Kooler but it does NOT fit--it is too big yet Amazon continues to link this Adapter to this particular Koolatron. It appears that the "Wagan 5 Amp AC to 12V DC Power Adapter" is the proper adaptor.
I'm just glad that I was present to unplug the unit before it burst into flames. I used to leave the cooler plugged in when I went home at night so I could have a cold soda in the morning (it takes about 4 hours to cool drinks if you just plug it in first thing in the morning). If the fan had gone out at night this could have been a big problem for me (and my company).
Answer: yes
