Choosing a wall wart power supply for a battery powered fan

[ewhitaker]

This is audio since I can hear the fan whilst it's running, right?

So I have a battery powered fan that runs on 4 AAs. That's 6 volts but didn't know what the mA was.

I bought a 3A DC supply and hooked it up to the motor. I started out at 6v, no current, and as I added current to where I thought the fan was running around the same RPM as with batteries, the voltage had dropped to about 3v, while reading 630 mA.

I am wondering what the best wall wart supply would be considering this info. Should I still buy a 6v 600mA wart, or something else?

Thanks!

Do the batteries last about 2-3 hours?

Seems like one of these would be less hassle and probably safer than a random supply...

I like the 1940s style of the one I have, and I'm a tinker by nature.

Somehow I knew this was as much (or more) about aesthetics as a supply.
..had to ask the question, though...
