All Sundanzer units use the same Danfoss compressor which draws 6 amps @ 12 volts = 72 watts when running. The small fridge only requires 2 hours of run time to keep cool in warm weather = 144 watt hours per day @ 25 degrees C ambient temperature. The larger unit uses about 220 watt hours per day. Still about 6 times less than the BEST unit from Future Shop. Greg’s tech wizard here… All Sundanzer units use the same Danfoss compressor which draws 6 amps @ 12 volts = 72 watts when running.

From the specs on their website it follows that it consumes 60-75 Whrs (Watt Hours) of ENERGY a day. In other words, in one day it consumes same amount of energy as an appliance with 75 Watts POWER would've consumed in 1 hour. I think the proper number for POWER would be obtained by dividing 75 Whrs by 3600 (because power is measured per unit of time, and 1 hour = 3600 seconds). Yes, there is some mystic 40-80W in their specs for 165 model, but this must be a typo. 80W is the power drawn by a mid-size 110 AC Volt refrigerator like those in dorms - you wouldn't like it on solar battery. I'm at the very preliminary stage becoming an off-grid "snowbird" in some old shack down South (if will live that long), that's why am interested. Thanks for the article!
