Hello everyone i've been trying to power my snes for a little while now without success. I recently came across This product at radio shack
and decided to give it a try.

It is supposed to be able to output 9v at 660ma, or 7.5v at 800ma. But when i try to power my snes nothing happens. So since for the life of me i cant get it to work ive got a few questions.

1. What polarity is the super nintendo (I know center is positive but does that make the system, +.- or -.+? Im thinking maybe i have the polarity on the plug backwards (currently its set + to tip, or -.+)

2. Does the snes require more than 800ma to power it? That is the only thing i can think of why the 7.5 @800ma wouldnt work...

3. Besides everything else does anyone know why this multi bank wont power my snes?

thanks

also i just tried a 9.6v nicd battery (on the multimeter it said it was outputting 10.7v however) with no luck. Im running things through the dc port. Is that part of my problem?

Well i feel like an idiot

For any noobs like me who need clarification on the polarity. If you use the radioshack Multi-Voltage Power Bank make sure NEGATIVE is at the tip. I just killed my backup snes by thinking it was +...

And to anyone who wants to know, the battery bank works like a charm. and should output anywhere from 1 to 7.5 hours of running time depending on your batteries..

So i dont think its a bad deal for $15, im now able to use 4 ni-mh batteries to power the snes. And i get a ni-mh charger at the same time

yep, the snes uses the non standard input of having the shield be + and the plug be -. You can save your snes, but you'll have to open it up and replace the fuse.
