    USER EVALUATION

    Battery generator use great

    Works great with battery generator 200watt ran for 8+. 300 watt portable battery generator 15 hours it used around 35 to 50 watts for 4/7 minutes at a time. Cycled off for 25 minutes 38 degrees. I use it my truck for food and drinks cold all day. I read the reviews about it it seems to be doing its job.

    Excellent Quality

    Outstanding refrigerator. Installed on my boat and it's been holding temperature for several weeks with good consistency. Have not noticed heavy drain on the batteries even in engines not running/unplugged from shore power for 5-6 hrs scenario.
