WAGAN 6214 14L Car Cooler & Warmer

I got this to replace a similar one I've had for about a decade (that one didn't break until it was inadvertently pushed off a shelf onto concrete). As with that one, this works perfectly well as long as you understand how they work.There is no internal fan to circulate air - there is a metal plate that gets cold or warm depending on which way you flip the power switch. If you put things in that are relatively insulated (things in cardboard, etc) or that barely touch the bottom metal plate, they will take forever to cool down (or heat up) because the heat transfer is from conduction (touching) and not convection (air movement). Juice bags that lay flat on the bottom cool down really quickly. Soda cans don't cool down as fast because not a lot of the can actually is in contact with the bottom.So: you generally want things that have flat surfaces to touch the bottom (and that aren't insulating), or... you just need to put things in that are already cold (or hot).Aside from that boring lesson on heat transfer, I wanted to add that this Cooler/Warmer is very well made given the price point, and I expect it to work as long as the one I bumped off the shelf. It has a good capacity, and it'll hold drinks and sandwiches on trips, which is exactly what I'm getting it for, and it'll also keep hot food hot (well... quite warm at least) if that's what you want instead.The included strap works fine, but this will always be a bit awkward to carry.If you have an area between your seats to set it, the cup holders on the front are nice, but if, like me, you don't, well... they're fine, just not really as necessary. You need a decent amount of room for it if you put it behind a car seat (seat in a car, not child car seat), because the lid hinges open, so you might be able to fit it, say, behind a passenger seat, but not be able to open it en route because the lid hits the back of the seat in front of it.Sound-wise, it is about as loud as a fairly quiet room fan. It's not noticeable in the car, and it won't keep you awake in a hotel room - if you get the 120v to 12v adapter (and I highly recommend that you do - among other things, you can pre-pack the night before and leave it plugged in to keep things at temp, and then you can also use it in your hotel room on the way).

me gusta que alcanza temperaturas de 12 grados en menos de 20 minutos, en todo el contenido ., me gustaria que tambien incuyera la opcion de conseguir el adaptador de corriente 110v

Compact

We use on trips and it keeps everything cold without ice which takes up space. There are only two of us so there’s enough space for a days worth of snacks that need refrigeration. Perfect size for the back seat, light weight, opens easily and it looks like it will last a long time. Actually surprised at its effectiveness. Just like taking food out of the refrigerator.
