12V fan question
Down here in Mexico, the temperatures are high. While we camp (in our truck camper) without hookups, we can't run the AC (technically we could, since we have a generator), so we're looking to get a f...

"DOWN HERE" is pretty self-explanatory. FanTastic, Eggs Benedict, Solar Panels and Truffles are just a bit impossible to find.
The noisier the fan the worse seems to be the efficiency. You're caught between the proverbial rock and hard place. Personal fans that won't kill your battery fast don't push a lot of air. Down "here" all the fans come from China. Don't buy a fan with metal blades, those are made for big rigs to keep windshields from fogging up and they eat more than a 15-year old teenager.
You have to KEEP AN EYE on battery voltage or risk destroying your vehicle battery. Go to a ferreteria, purchase an "el cheapo" hand held test meter for twice what it costs north of the border. When the vehicle battery dips lower than 12.50 volts STOP! That's the end of the line.
When you get home, then check into the Fan Tastic Fan Endless Breeze box fan. I wouldn't be without one down here.
Sailboats use fabric DUCTS that can be swiveled atop hatches. They SCOOP the breeze and can blow more air through a trailer or camper than two dozen electric fans. Fill trash sacks with sand and use them for weights to hold the scoop flaps down against the roof. Bending camping tent fiberglass poles work great to shape the scoop. Use ripstop nylon, DOUBLED or even TRIPLED for the fabric. This means some sewing. Doesn't work too hot on a calm day or night.
Hope This Helps
