My thought was the thermoelectric unit was small, and it was 12v, and I could build it into the lid of the ice box.
All true, but with a major problem 92 Amps a day that needs to be one hell of a battery.
I can hear you thinking only run it part of day
If you only intend to run it part of the day, another big problem rears its ugly head, when its switched off, it becomes a thermal link to the outside temperature which means rapid warming of the interior.
The other reason they dont like ice inside is because the unit is a thermal bridge condensation will quickly form on the thermo unit, its ok to use thermal packs (those sealed blue eutectic blocks)

Thats no Hijack it totally on topic.
Why not make the whole thing? the plastic on a bought unit acts as a thermal bridge....
With the styrofoam cooler as the internal part, adding foam insulation, there would be no plastic...just layers of foam and foil backing on the outside to reflece heat.
why not use these instead of ice?
Saves draining melted ice, easily reuseable
The re-freezable packs are a good idea. Also, I can use half-gallon milk jugs of water frozen. When it melts, you have drinking water. The milk jugs are better than 2-liter bottles as they are square and fit better in the cooler. Also, water frozen in large baggies can be used. You have ice in these to break up and put in drinks.
