I can see on my peltier fridge right behind me, a 55W rating (its smaller than the nucool). I was under the impression this was more efficient than a compressor model. I dont see any flaws in your math, other than perhaps it runs at lower than 50%.
Ha, I believe that's called "marketing". Peliter coolers aren't horribly inefficient at low temperature differentials (e.g., 5 - 10F). But, that's NOT what we're discussing here.
From Wikipedia:
Thermoelectric junctions are generally only around 5–10% as efficient as the ideal refrigerator (Carnot cycle), compared with 40–60% achieved by conventional compression cycle systems (reverse Rankine systems like a compressor).
