I have looked on the RCX and I've noticed it does say "9-12V ~". From
what I've gathered the "~" means polarity doesn't matter. My concern is
the mA rating of 9 volt adapters. Radio Shack has about 6 different
types each with a unique mA rating. (eg. 300 mA, 500 mA, 800 mA, etc.)
My question is, could the wrong mA rating damage an RCX?
Later,

| (...) No. If you take one with too small a current rating, however, you could overload the Power Supply and fry that. Or, maybe, you'll find that oyur batteries still drain even with the RCX plugged in :) I would think 800 mAmps should be enough, (...) (26 years ago, 24-Jan-99, to lugnet.robotics)
