Never heard of it, link?

I've used a 12 volt cooler before while boondocking. I also have a small solar array that unfolds on the roof of our camper. I've got 2 150 watt panels that unfold and are adjustable depending on what longitude we're at.

Just keep in mind that for every watt hour you plan on burning electricity you need 1.25watts worth of panels.

Ex: light bulb burns 100watts for 1 hr = 100watt hours of power so you'd need 125watts worth of panel to replace the used power in a timely fasion.

For a die hard dry camper this seems to make sense as it is a direct 12V connection that could either be connected to your batteries without the need for an inverter. It can also be hooked up directly to solar panels with no batteries or controller required. I guess it is insulated well enough that everything keeps OK over night when there would be no power available.
I am not sure how practical it would be for a traveling RVer but it sure looks like a good idea for someone living off the grid.

While I don't know anything about the Sundanzer model, a freezer is nothing more then an insulated box, a motor-driven compressor, a condensor and some coolant. I've no reason to suspect Sundanzer's model would be inferior to any conventional freezer. The main difference being that "portable" models are driven by a dc motor, vs the ac motor of fixed/home units.

My only gripe with all these "portable" freezers is their bulk, and when time permits I'll be exploring the possibility of constructing an in-cabinet dc freezer for my Winnie.

Just some info that may be useful.
For abt 20 yrs I had a DOMETIC 12v/120v/ GAS freezer that we used on our boat. 2 cu ft top load as are the ones discussed in this thread. Kept ice cream hard as a rock. One problem was that on propane NO thermostate so it on all the time. I would just turn it off for the night and back on in the am.
Dont know if they are still on the mkt.
