User questions & answers

Question:	Would this keep drinks cold on an outdoor patio
Answer:	This unit will keep things about 20 degrees cooler than the outside temp at best. I freeze a couple of water bottles or a freezer pack and it will keep things cold much better. Takes about 10 hrs or more before the frozen bottles melt enough to drink with the outside temp at over 90 degrees.
Question:	What mechanism generates the cool
Answer:	40 Quart PowerChill Hot/Cold Thermoelectric Cooler Take some cold drinks on your next road trip while leaving the ice at home with a Coleman 40 Quart PowerChill Thermoelectric Cooler. More than a cooler, but not quite a refrigerator, it cools up to 40 °F below the surrounding temperature without any ice. So if you use your cooler in an environment where the temperature is 70 °F, this cooler will maintain an internal temperature around 30 °F. You can use it like you would any other cooler except, instead of throwing ice inside, you simply plug in the 12V car power adapter. Then add your pre-chilled drinks and snacks. Your cooler will reach maximum coldness in about three hours (you can speed this up by adding Coleman ice substitutes) and stay cold as long as it's plugged in. Large enough to hold 44 cans, you'll have plenty of space for refreshments for the whole trip, and you can keep all your contents organized with the storage tray.
Question:	Can it be powered with a battery
Answer:	Sure....It is 12 volt, so it can be powered with the included cigarette lighter cord, or from any 12 volt battery with the appropriate cord for connection.
Question:	How long can it stay plugged in before draining battery
Answer:	That question depends totally on your battery supply. Mine runs off of 2 -12V batteries and I can leave it on for 12 hrs or more before I have to start the truck and make sure the batteries don't get past half used.

User questions & answers

Question:	Will this keep frozen meals frozen solid for 20 hours in the car
Answer:	Our unit did not work at all and we had to return it
Question:	Does it have a strap
Answer:	Not really sure I thought I had read 850 sq ft. I have a 250 sq. ft bd rm & cools excellent on the lowest setting.
Question:	would you be able to put plastic containers inside of it to warm up food or would it melt them
Answer:	Thats a Great question. It isn't in the manual on how to remove the water it just says what you can clean it with. You cannot remove the drawer because the pump is hooked up and I dont see a plug to drain the water. I tried a sponge but that took too long. The thing that worked best is a turkey baster that sucks up the water. Poor design by the company. If anyone has a better answer please let me know.
Question:	What if you make short trips which means your vehicle will be on an off will this damage the unit
Answer:	Yes you can. I have put ice in mine, however it only give you a momentary blast of cool air for a lil while. I’ve learned to just let the water cool off the temperature in the room.

User questions & answers

Question:	So why does it need to be used with ice or the frozen packs? Seems like that defeats the purpose lol
Answer:	It keeps the cooler cold if you stop and turn acc feed off. I make 3 or 4 stops 60 to 90 minutes and it keeps lunch and drinks cold.
Question:	would this function like a regular cooler if I was not in a position to be able to plug it in could I just put ice in it and would it stay same like t
Answer:	Yes, you can use cooler packs or ice. I use the cooler packs even when using it plugged in. My car accessory plugs do not work when the car is off. So on trips when I stop the cooler packs keep things cool, and don't take up much room in the cooler.
Question:	Can you put ice in it
Answer:	I know of no reason you could not, but not sure why you'd want to. The cooler itself is much like any regular cooler, but with the Thermoelectric heat exchanger in the lid. It would not keep ice frozen as it will operate at ~ 40 F below ambient temp. If the ambient temp is 75, it would stay around 35-40F.
Question:	Does this have a wall outlet plug as well
Answer:	No, that has to be purchased separately.

User questions & answers

Question:	What size solar panel does it take to power this, or if anyone has tried it
Answer:	This thing uses a surprising amount of electricity. And it's VERY poorly insulated, so as soon as it stops running it heats up quickly. In full sun, a 100w solar panel will work, but no matter where you are (assuming the US) you'll only get 4-5 hours of full, direct sun per day. The other problem is that this cooler is very poorly insulated. The top isn't even airtight. So that means it will start to warm up about half an hour after the sun is no longer directly overhead. To get around this you'll need several (3-4) 100w panels and at least 100-150 mah of battery storage if you want to keep something cold for one day.
Question:	Is there a power cord with this cooler and how long is it
Answer:	Yes, it has a 9 ft long,12vdc power cord. One end has a plug that fits into a lighter socket, the other end has a plug that connects to a short cable on the unit. It can be connected to either produce hot or cold depending on need.
Question:	Does this thing run constantly (and draw constant amps) or does it cycle on and off like a regular fridge
Answer:	The fan appears to run constantly. When using the adapter indoors the same is true so I think it is set up to run all the time and maintain a roughly 40 degree temperature drop from the surroundings. When we travel in the car, we put a couple of frozen water bottles in at the beginning of a trip. These allow us to stop for several hours of sightseeing without having the cooler get warm. WE stopped for as long as 5 hours and everything was still nice and cold when we got back to the car. On a recent 23 day trip out west, we took it into each hotel at night and plugged in the adapter. We probably used hotel refrigerator freezers a half dozen times to refreeze the bottles and when we got home we still had ice in the bottles. The nice thing is that with this cooler, everything stays dry and you don't have to get dripping water all over everything when you want a drink or worry about things falling into the water in the cooler. There is no water in the bottom.However, the cooler does draw significantly so you would not want to leave it on when the engine is not running in the car. We don't have that problem because all our outlets are controlled by the ignition key.
Question:	Can it be left on overnight and not run the battery down? Are there molded in carry handles on the sides
Answer:	Yes there are molded handles on the sides. I am a truck driver so this goes in the cab of an 18-wheeler. So I cannot say whether it would run down a car battery if ran overnight and the car is off. This works great in the cab of my 18-wheeler, it is rugged and can handle the bouncing around in an 18-wheeler. Previously I have used the Coleman plug-in coolers and they only lasted a few months. Hope this helps.
