Question: Is the 12 volt adapter included?
Document: I bought this as a &#34;prize&#34; to be given out at my work (construction job)...I picked this particular model because it said it &#34;works with Koolatron A/C to D/C adapter...which I mistakenly thought would be included...granted it didn't say explicitly that it was included, but it did seem that way. I did finally find an adapter, but it was $32. Ugh.
This Koolatron 12 volt lunch box is heaven sent, my family works weekends and we use it to heat up home cooked meals, it is fantastic, the food is so hot that we have to wait to let it cool down a bit before eating but it's nice to have a hot home cooked meal instead of fast food and we save money too, great product, highly recommend it!
I would rather pay a little bit more (although NOT $32) with the lunchbox to have it included (they need their lunch available on-site, not in their truck) than to have to buy it separately. Otherwise a good product.
this works great! my uncle uses it in the field while he's farming instead of eating a cold lunch he can warm it up right there in his rig!
perfect gift for those who travel a lot. i brought it as a birthday gift for my father since he travels away a lot and always ate his food cold. this works perfectly connected to your car's cigarette socket.
ordered it as a gift, he really like it and it works it will heat up your lunch in no time.
it look like a big but inside is very very small it ok for 5years baby only. it is nice but so small.
Works like a stove. Can cook a canned soup in 45 minutes to an hour. Great for those that work out of there vehicles and want to eat a warm lunch. No more cold cut sandwiches.
Will I buy again? Probably, I need to know if mine was just poorly made!
This was the answer to all my husband's lunches! He is a happy muncher! Quick, efficient, and handy, I would recommend this to anyone who has to work on the run and outdoors.
Answer: yes
