OK, mine ran continuously, but by the next day, the water bottles were frozen solid.

Yeah I have those ice trays...

But 5 min every hour... Of course there is NO insulation in the lid right now... The compressor draws about 3-4 amps running. Yeah, I had lots of battery power.

I'll go with what Greg said and have the unit recharged... and then add the vacuum panels.

5 min every hour, eh? OK.
