Solar Cooler

[Greencorner]

I have seen these but never had a use for them myself. We have a plug-in cooler for our van that plugs into the vehicle's outlet & we use that when going to the store or transporting cold stuff long distances.
I would prefer solar myself as it's renewable & rechargeable.

I have never seen and thought AC would be in vehicles, do you put water in your Van cooler? I planned long back to make a small one for me during summer, but havent yet.
