    Red face Plug in/thermoelectric coolers

    We are in an 18 wheeler all the time - driving all over USA and Canada. We got a Wal-Mart fridge hoping that would work but it wouldn't run - made our inverter go to "fault" all the time.

    So we got a Koolatron cooler - supposedly really good name brand from what I read. It ran fine for a day then quit. I've gotten it to turn back on again but it runs a few minutes then quits. It's way too warm in there and, once again, we're going to have to throw out food. (68 degrees in truck, 60 degrees in cooler - supposed to be 40 below room temperature so really cold)

    So I'm wondering what your experiences are. We did use an adapter to plug in the cooler so it won't run our battery down to nothing but it doesn't run just plugged into the 9V adapter OR into the inverter. The inverter is fine as we run the microwave off it and toaster and it works perfectly.

    I'd love to buy one of the new fangled fridge/freezers made especially for truckers etc but at $400 to start, they're too pricey for me as of yet.

    We have an ice chest cooler I use for drinks but want a regular no ice cooler for milk, etc., that would spill if tipped or floating around in ice.


    What brand name have you used? Does it keep stuff REALLY cold? Have you had yours for years? Does it still work well? Did we maybe get a defective one just by chance? What name do you recommend?

    Any help would be greatly appreciated as it's getting really frustrating throwing out food because it just spoils



    Thanks

    I've had similar problems with the cheaper thermoelectric coolers. I think part of the problem is that some of the coolers - like mine, a Coleman 40 qt, have fuses in the 12v power connector. The included fuse is a mere 7.5 and I had the unit causing faults like you described. The 7.5 even began melting after time, although it still kept the circuit going. Finally, it gave out. I have been using a slightly larger current fuse, mainly because it fit, but also to see if a larger fuse will work better.

    I may be doing something wrong, so take that above as my personal experience, not direct advice.

    i had the same problem with my coleman. i went through 2 plugs for it because it wasn't making a good connection. wires and plug getting hot enough to melt. i finally pulled out the 12v plug socket in truck and hard wired the fridge. PROBLEM SOLVED the wires don't get hot any more.

    Well, we picked up a 40 qt Coleman at a TA stop last night and it's working perfectly!!!!

    We're running it through an adapter so you can plug it into your house but we're plugging it into the inverter we have, which shuts down if the truck battery gets too low since there's no alarm on this truck's battery.

    It's a Koolatron AC-15 adapter (Description:
    Product Description
    Provide 12 volt power to your cooler anywhere there is a normal electrical outlet. Power other 12 volt accessories up to 5 amps power draw. Use the cooler as a bar fridge, or in the garage for a cold drink while working in the yard. Load the cooler for a picnic or road trip the night before and leave it plugged into the adapter, then transfer to the car in the morning for a quick get-a-way. Students can use their coolers in their dorm rooms. Lightweight, solid state construction with automatic reset circuit breaker to protect against over load or over charge. What can you power with a Koolatron Power adapter Koolatron and other 12 Volt DC thermoelectric coolers Koolatron 12 Volt DC Massager Koolatron lights and fans Other 12 Volt DC accessories that consume LESS than 5 amps.
    [from Amazon's site link - I can't post links yet )

    So far, so good. It's been running about 12 hours and nothing is even warm, let alone hot. Hopefully this will solve our problems for a good long while

    For about a year and a half I used this Igloo Koolmate

    http://www.walmart.com/catalog/produ...uct_id=3353216

    Worked flawlessly...only down side is making sure the temp inside was cool enough. 40 degrees cooler is NOT accurate, more like 20 degrees. I used a wireless thermometer to keep things in check. In fact, I still have the cooler (anyone wanna buy it? CHEAP) Finally stepped up to a fridge.

    Thumbs up

    I used to have a old coleman cooler that would freeze drinks. The new ones are junk. I lost count how many times I took it back. 2 or 3 and had 1 of our drivers say he had 5 in less than a year. I went with an igloo this last time and it is working great!

    Well, the Coleman is still working great. Things are nice and COLD and no problems. I still want to go up to a fridge but they're way too pricey for now

    I bought a GE at Wally World for $119, with a 800 watt inverter it worked pretty good. I just bought a 2500 watter now.
