Arik 565 Posted May 3, 2011 Report Share Posted May 3, 2011 Is there a way to put a small fridge / freezer in a car (trunk) without killing the car battery when the car is off? Quote Link to post Share on other sites
BobAsh 582 Posted May 3, 2011 Report Share Posted May 3, 2011 Propane fridge, like RV's have. Quote Link to post Share on other sites

BpS12 512 Posted May 3, 2011 Report Share Posted May 3, 2011 Bob's right. And insulate the crap out of it. A down side may be weight of the unit plus the propane tank. Think of maybe adding airshocks if needed. Also, don't mount the tank near the rear of the trunk, just in case. If you have to go electiric, add a heavy guage extension cord and be able to plug it into an outlet/generator. Solar trickle chargers may help or if you have a roof rack, mount larger solar panels in between the runners/bars. Every little bit helps. As for "if it's enough?" I don't know.

BuffetDestroyer 969 Posted May 3, 2011 Report Share Posted May 3, 2011 Our government will tell you to put a big-ass $5,000 solar panel and wind fan the size of your car on top of the roof! You will then get enough energy to keep the refrigerator working for up to 5 minutes in a perfect sunny and windy day and your gas mileage will only go into the single digits if you actually try and drive anywhere! All joking aside, the propane type is probably your best bet! Quote Link to post Share on other sites
datrowl 111 Posted May 3, 2011 Report Share Posted May 3, 2011 (edited) Could also stop into any truck stop and get an electric cooler/fridge like they use in 18 wheelers... hard wire it... and use a battery moniter/auto idler... moniters your battery charge with a set floor and will crank and idle the car to build charge when it nears the floor setting. Likely wouldnt cost anymore than a propane unit and would be a damn sight safer than keeping a propane tank in your trunk... Its the solution OTR drivers have been useing for years and it works well, why reinvent the wheel? just thinking of options...

G O B 3,516 Posted May 4, 2011 Report Share Posted May 4, 2011 Use a regular AC fridge and an inverter. Use a two battery system. Separate the fridge battery with a large diode. An RV shop will know how. 1 Quote Link to post Share on other sites
Kliegl 304 Posted May 4, 2011 Report Share Posted May 4, 2011 That's the best way there. A cheater's way would be to wire a good lead off the positive power point into a heavy relay controlled by ignition switched power. It would only run when the ignition was on.

2glocks 4 Posted May 4, 2011 Report Share Posted May 4, 2011 HMMM no one ever heard of a thing called a cooler, seriously, get a good cooler, put inside a homemade box with great stuff foam, pack with ice, will keep frozen stuff froze for at least a day in 90 deg weather Quote Link to post Share on other sites
DogMan 2,343 Posted May 4, 2011 Report Share Posted May 4, 2011 I agree that a GOOD cooler and ice are the way to go. Super simple and no mechanical worries. You get what you pay for with coolers, too. I have a "Yeti" which is about at the top of the line. $325.00 and worth every penny. It will keep food cold for days and it is actually certified as a bear proof container. Quote Link to post Share on other sites
G O B 3,516 Posted May 4, 2011 Report Share Posted May 4, 2011 Altho not mentioned here, AVOID DRY ICE IN A CLOSED VEHICLE! CO2 from dry ice in the trunk could easily asphyxiate the occupants of a vehicle. Quote Link to post Share on other sites
