I work 2nd/3rd shift where it gets extremely cold. Would this heat my food in 2.5 hours if left in the car or would outdoor temperatures interfer?

The temperature tops out at about 300 °F and would dry out or burn the food. I usually put the food in about a half hour before to warm it.

There should be no problem at all. It wouldn't even take that long to heat your lunch. It's a great product!!

It will get cold but they work so well u will not need it on all night. The trick to staying warm with this heat pad is a thin blanket on top and a comforter to hold the heat in. I recommend this item for all drivers.

It does keep your food warm for a good hour or two depending on how hot the food is when you put it in the Bentgo. But I have found that if you put the Bentgo in an insulated bag, it stays warm for 4 hours.

I left it in my car (I live in florida) and it was at least 105°. A week later, I used to put out an engine fire. I think it depends on the duration.

So far I have only had it plugged into the AC to 12v adapter in the house and it maintains a temperature that fluctuates between about -3 and -8 deg F easily. I would expect it would do as well plugged into a lighter receptacle in 80 degree temperatures. It might not get all the way to the -8 max cold in 90 degree temps in the direct sun but it would probably be able to maintain 0 at least. I will eventually be using mine in a motor home full time and I'm sure it will keep my pizzas frozen rock solid. :0)

about an hour or 2 depends on how cold the item was when you put it in there

I think that you would have to experiment with that length of time, and the temperature outside the cooler would be a big factor. If it were indoors and not in direct sunlight, I think that one of these might work for nine hours in a small cooler filled with cold food. If one isn't enough, you could try two of them. If it were outdoors at high temperatures I think that just one of these would not work.

Hello! I'm not 100% sure about heat as my sons school asks we not pack up items to be heated but it stays cool for about 2 hours. Longer if we place an ice pack on the exterior lunch box we purchased. Hope this is helpful!

It is suggested to turn it off every time. It does get very hot after about 30 mins. I think it would continue to take power. I am happy with it as it will really warm you, but i worry about it, so as soon as i am very warm i turn it off and unplug it. It works very well with two seats also. It is great for those miutes when the car heater isnt hot yet or you are still defrosting the windows, you will be warm.

Well, the owner's manual warns only against leaving the unit in the car for very long because if it's too hot, like here in Arizona, that could harm it internally. I place it on the dashboard of my truck when driving and it works just fine. As far as cold weather, I haven't had to deal with that. I hope that helps you.Tony from Arizony

Mine turned off when the car engine was not running. I don't know long the items will stay cool for. We only tested for six hours with no power. The food was cold.Hope this helps

If you are traveling anywhere that will be warm, I'm guessing the food will not be very cold by the next day. If you intend to eat most of the food, then it should be okay.

I have a two car garage that's fairly well insulated and rarely see the temp below 50 on the coldest days. Normally 60. Cars have instant heat because of the heat. This is the second year using this heater and it just hums away. Hope this helps. Oh yea attached garage.

Depends on how cold the food is but usually less than an hour. And then it keeps it hot until you want it. I love it and use it almost daily.

It cools 40f below the ambient - so if you have this in a room temp environment (70-75f) then it should attain (30-35f), ie very cold. If you have it in a car where its usually warmer (85-90f) then you get warmer temps (85-40=45f)... still cool enough to store dairy. Now this depends upon the claim of cooling 40f below ambient actually being true.

No. I put in ice packs with my food. I unplug it when the car is not running and everything has stayed cold for at least 4 hours with it unpluged. The ice packs are still frozen and just a tiny bit soft.
