I am curious as to what the estimated cost of running the Dometic refrigerator on electricity is per day? I know there are a lot of variables that factor into that cost, so I am simply looking for a ballpark figure. Our home refrigerator died and we are storing perishables in our Casita fridge until our replacement gets delivered. We store our trailer in the neighbor's driveway across the street, and would like to reimburse him for the electricity used. Therefore I am curious as to what would be a fair daily rate? $1/day? $2/day? Thanks!

Obviously, it depends on the wattage of the refrigerator element, how long it is on, & the cost of electricity, so it is difficult to guess.  My refrigerator has a 240 watt element and is on about 70% of the time in 70°F weather. A fair guess would be 4-5 kWh per 24 hours.  At $.20 per kWh, $1.00 per day would be fair...

For $20 or so you can buy a "Kill-a-watt" meter at a big box building supply store.  It will show operating wattage and other values and firm calculations can then be made.  Cheaper to just go on the high side when repaying your neighbor.  I've used the meter to find start up and operating  wattage of refrig and furnace at home, Casita 16' AC start and operating wattage.  Marginally useful device as it gives info but I need those appliances regardless of electricity cost.  Let's me know if my 2KW generator can operate a device.

I've been using my Casita refer as my Beer Cooler since my DW kicked me out of the "Beer Crisper" in our House Refer. I was a bit shocked when I put my KillOWatt on there and saw it pulling 200W. That's a lot of juice, no wonder my electric bill has gone up so much. Looking for a used Dorm Refer on CL now.
