I believe it's fairly likely that a battery in decent shape could run such a fan on low for about three nights without doing any harm. If I'm figuring correctly, with a typical small battery rated at about 85 or 90 amp-hours, three nights of just the fan should take the battery charge down about halfway.

My Fantastic fan on "Low" draws just under 1 amp so if i ran it for 3 nights at 8 hours each night that would be a total of 24 amps.....use the thermostat on it and you can drop that figure even lower. I really like that fan as it moves a lot of air and is very quiet.

When you charge your battery out on the road/campsites... do you use a regular AC battery type charger? Do you need to unhook everything from the battery while charging? Thanks

The first summer with my trailer, I ran a test of my solar panel / fantastic fan setup. I unplugged the trailer from shore power, enabled the 100W panel, and turned the fantastic fan on low with the thermostat set cool enough to ensure it'd be running 24/7. (My batteries have 110 Amp Hours of energy storage capacity combined.)

The test continued day and night for 30 days. After a month, the batteries were working just fine. That was 3 summers ago and I still have the same batteries which are doing great. I don't imagine you'll be harming your battery using it for the fan on low at night and allowing it to recharge from you vehicle's alternator as you head to your next destination.

I have been running my Endless Breeze fan (A portable version of the Fantastic fan made by the same company) all day long for over a month now. It often runs for a couple hours in the evening when I get home as well.

I am using a 100w solar set up and a group 29 battery (120aH). I have no want for battery power for lights or water pump etc each day.

Keep in mind, I am stationary and have no other way I charge my battery.

I could use a charger when I run my generator, but I just don't need to. You should be fine with an average charging system.
