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.
Good Service
I'm blown away by the exceptional service! From the moment I inquired about the product, the customer service team was incredibly responsive, patiently answering all my questions and providing detailed product information. They even followed up after my purchase to ensure I was satisfied. Installation was a breeze. In less than 1 hour, the job was done, with neat wiring and a sleek finish. Now, I can enjoy a cool and comfortable driving without any hassle. Colku truly goes the extra mile!
