I like some of Smittybilts products, but when it came for a 12v fridg freez, I went with Engel. I have their 22qt. 12v fridg freez & the draw is only .7 to 2 amps. My solar system on my trailer will supply more than enough power & then some for all my 12v accessories for short or long stay camping trips. As the saying goes "you pay peanuts you get monkeys" or aka "buy once cry once."
