Recently purchased the AJ40, received it super fast, unboxed it, and set everything up following the owner’s manual. Plugged it in, set it on 33*/MAX mode and in 10-15 minutes this cooler was a chilling 33 degrees!
Love the ruggedness of the cooler’s build and am well pleased with what I’ve seen thus far!
I left a bottle of water in the cooler with it plugged in to a/c power all night at the settings mentioned above - long story short the water bottle was chilled to super cold perfection without freezing! Wow - I’m super impressed and excited to take this thing on my next road-trip! Love it…
