Well i happen to have a very strange question. You see i went to a rc swap meet yesterday and was able to pick this charger up for about 10 bucks. http://www.hobbyzone.com/images/stock/EFLC2010.jpg The only problem is that this charger only accepts a 12 volt dc current in because its ment to be used with a car battery on the go. I searched around radio shack and others for a power supply for this thing and a power supply that will supply enough amps would cost about 40 bucks. Defeating the purpose of the "cheap" charger. So i was wondering if i could rig it up to use an old computer power supplys 12v line. I was looking at specs on newegg on psu's and it looks like on average, the 12V line outputs around 12 amps. Since the charger only pulls 4.5 amps at most. Do you guys think this would work?

computer psu for charger psu? would this work PLEASE HELP ME

if you had the right transformer, it would be really easy to make your own power supply. dont you have any 12V wall adapters or something?
the computer power supply will also work. you can probably just use the one thats in your computer. yellow, i believe. (black is ground)

No there isnt a wall adapter for it because its a "portable charger" for the field. I was looking at radioshack and the "wall wart" type transformers only deliver about 1500 ma. The charger has a varible charge rate and at the highest can pull 4500ma.

4.5 amps is a bit excessive though, what the hell do you want to recharge at that rate!? 
My car battery charger pumps out 1.7 amps!

I've often found if people spend less time worrying about what someone the other side of the world has posted on an internet forum and more time getting laid, they'll be a lot less tense.
1500mA (mAh is a measure of total current per hour. mA is a measure of current. battery capacity - mAh; electronics power output/consumpton - mA) is more than enough to charge your batteries. a typical nimh charger uses approximately 250mA to charge two AA's (im not sure if thats current per battery, or current for both, its not specified on my charger). anyways, unless you have more than one cell in parallel, i would not reccomend ever going past 1500mA anyways.

Well thanks for clearing the "mah - mA" deal up for me because i was very confussed. And i hooked up a computer power supply and its working great. Charged up some cheaper batteries to test and they work just fine.
To answer your question wayne, you can charge "RC" batteries at a max of double the amperage of its overall capacity. Like on my NIMH stick packs they say dont charge higher than 4 amps or you might heat them up and thats bad on NIMH's.
Now for another question. If you had 30amps but only at 1volt. Would that kill you? Would there be enough voltage to push it through you? because there is a fuse on the charger that says 7.5amps at 35v. Is 7.5amps different at 35Volts than it is at 12volts? because i'm feeding the charger 9amps at 12 volts but the fuse didnt blow?...
I'm just kind of confused. "how do you spell confused"
