Fantastic Fan and Battery Drain

I was just thinking about overnighting while traveling from FL to WY over the summer. I know we cant run the A/C off battery but can the fantastic fan run all night without draining the battery to the point of damaging it? I know furnaces run all night but their fan kicks on and off. A fantastic fan would run non-stop. I'm thinking it will be quite warm in the Southern States the first night or two till we get farther North and West so trying to figure out the best way to move air while sleeping. Any suggestions or should we just plan on hookups til we get to higher elevations?

Thanks!

Melissa

I don't have one yet but I understand that they draw very little power, also I believe some have a thermostat that can turn it on and off during it's use.

What model do you have?
This Model 4000R

Performance:
AMPS

High 3.00

Medium 2.29

Low 1.86
Also depends on what amp battery you have. And how long it will last.

I have a fantastic fan with 3 speeds. I've run it all night on the lowest speed without any problem.

Check this site for the Fantastic Fan. It appears that they are less expensive than joining the camping club price.

We dont have one yet, just researching to know which one to get and how long it can run off battery. So are those numbers how many AMPS per hour is uses? In 8 hrs it would use 24 AMPS on High? Am I understanding this correctly? And how many amps can you drain a battery down to, 50% or something like that?

Thanks!

Battery condition and capacity will affect the answer you seek. Some are more able to endure what your planning to do and some wont.
you'll need a battery of big enough capacity and in good condition to put up with that nightly. recharged daily.

FantasticFan Amp Draw

Hi Mellissa,

I tested my Fantastic fan 5000 RBT before installation
and it only drew about 0.4A on low once it got up to operating speed.
Think it is just like yours with the addition of a thermostat.

0.4A x 10 hours overnight is only 4AH and easily supplied by most
onboard batteries.

Bon Voyage, Larry H

Thanks for all the great input. Batteries is something I know nothing about as we've always camped with hookups. I plan on researching threads here to learn about batteries, amp hours, draw etc.

Thanks!

I had one with a thermostat knob in my last trailer. I believe the switch can even be added to existing fans without one. The switch works very well and it is easy to turn the knob till the fan just comes on. Then when things cool off it will turn itself off till the trailer warms up again. That will save some of the battery while you sleep. I ran mine all night several times with the one battery trailer and still had plenty of power the next morning.

I have a constant breeze fan, close to the same thing. I haven't checked the power consumption, but I can tell you I've run it a couple nights lately without worry about battery drain. It wasn't a problem.

To put it in perspective, the fan on high drawing 3 amps would be like having 2 lights on, most of the 12 volt bulbs inside a trailer would be 1-2 amps each.
