Out of curiosity, along with the output limitations on the NXT (1 A) and RCX (500 mA), does (...) (17 years ago, 8-Oct-07, to lugnet.lego, lugnet.robotics.nxt)

I don't recall all the stuff I learnt about the relationship between VA and W, but that seems to me to indicate about 0.7A. I believe this generally reduces as load increases, (...)
