is it possible to connect an AC device to a DC source?

only if you go through an inverter. A DC voltage will not drive an AC device.

You will need a 100-300watt inverter (it converts the mains to 12 v dc) which can be bought at a reasonabl price or as suggested buy 12volt dc fan which will run direcly from a car battery.
No you cant connect an ac device (induction type motor) directly to dc

Yes if you want to spend more money than it costs for a car fan (12 VDC).
Radio Shack carries a small inverter that plugs into a cigarette lighter in a car. Therefore you will need;
1- The inverter (about $37 for a 100 watt unit) ((this was 5 years ago).
2- Wiring and a car cigarette lighter socket.
3- 2 battery clips (1 red and 1 black).
Do you think it's worth the expense?
An auto supply store probably has a small 12 Volt fan and you will still need Items number 2 and 3.
Good Luck ! ! !
I forgot to ask "What is the voltage requirement for the fan?"
If it is 12 Volts DC then "Yes" if you wire it correctly (if you do it wrong, it will run backwards & you will need to switch the wiring to opposite the way it was to make it go forward.

In a word - no.
You need something called a static inverter to change DC (Direct Current) to AC (Alternating Current).
Yu could connect a 12V DC fan to a car battery

laptop followers regularly do not draw plenty contemporary. If this "small section" isn't on the topic of an vehicle, why use a motor vehicle battery? you need to use low-priced 12V DC ability packs plugged into the mains. check out the fan automobiles for a contemporary or wattage score. this might help you opt for a suitable small grant.

If it's a cheap fan, only one way to find out. I think it'll work but may soon burn the fan out.
But, if it's a good car battery, expect to shorten its life by draining it on an appliance.

Yes so long as it is no more than 9 volt.
No. Ac currant is accumilated, Dc is direct current, it will burn out.

No, but these people have the solution to your problem wrong.
Yes, they're right, and you need to make 12V DC into 120V AC,
OR
you replace the motor in the little fan with a DC motor. Much easier.

Fordman answered susinctly. The issue is taking 12 volts up to 110. There are also converters as you may realize for reduction.
Consider a Cell phone as an example. It can be charged with two different chargers; car and house, but both have the ability to convert, and not affect the phone adversely.
