Question: how long does it last on car battery
Document: Perfect for long road trips, especially if your like me and like to pack some homemade sandwiches. Took it everywhere last summer throughout my Alaskan fishing adventures. Holds cool temperatures for awhile even after unplugging.
It cools to 40 degrees cooler than the surrounding air temperature so if you leave it outside when it is 60 degrees you wind up with 20 degree frozen Gatorade! I use the 120 volt cord to power it. I don't know how long it would work in a vehicle until depleting the vehicle's battery. The 12 volt socket pops out of the female 120 volt socket so I Gorilla taped them together.
And that's a cheap replacement part. You can usually find fan motors for these things at just about any truck stop. I've had the fan motors last for as long as two years and as little as six months. I've also heard of people throwing away a perfectly good cooler and buying a new one, or something different, when all they needed was a little $10 or $15 fan motor that it takes about 10 or 15 minutes to replace.
I've purchased this cooler (older model) at Walmart 10 years ago for $60, and it still works great! The last 2 years I have kept the coolor plugged in 24/7. I plan to buy the new model to replace this one soon and give this one to a family member.This coolor is great because you can fit a lot in the cooler since you don't need any ice, and on long road trips it's great, since it will stay cool while enroute.Buy this cooler!
Also because the light color design gets dirty looking quite quick while camping.I never used the heating option so I have no comment on that feature.It will drain a car battery, so don't plan to plug it into the car battery when you are not driving.
We own 3 of these coolers and have one in each vehicle including the semi my husband drives. The first one we got both cooled and heated. I never go grocery shopping without it and our kids use it when they go camping, especially where there isn't an electrical hook-up--you can keep it running off your car battery.
We bought this cooler to take on weekend camping trips. Since we have a portable battery, we thought it would be perfect because we would not have to run it off our car battery and risk a dead car.The cooler took up quite a bit of space in the back of our large SUV, due to the size of the cooler and the cooling mechanism on the back.
I'm not sure what planet some of these negative reviewers are coming from, but I've used one of these for several years with very few problems. No, you don't leave it plugged in in your car when the car is not running or, yes, you run the risk of running down the battery. Common sense (getting to be a rare thing these days) should tell anybody that. Nor will it keep ice cream frozen.
It also helps to load it with prechilled items (chill them in the regular fridge overnight first). Finally, keep it plugged in as much as possible, but be careful about leaving it running in the car without the engine running, as it will pull the battery down. Also, I have found that the unit works best when sitting upright (not like a cooler) with the fan on the top.
You could of course keep it plugged while in your car, but it'll slowly drain the battery- the thought of being stranded, I find hampers the serenity of the great outdoors. So, in all, it mostly worked, but it's kind of a specialty item. It's also pretty large, borderline a pain to haul in and out of the vehicle. It's best suited to situations you may not run into too often- so, if you buy one, you might be leaving it home as often as not.
Answer: yes
