(...) You must be dealing with a different release of the battery pack than I am, since the only portion of the US instructions that mentions numbers states the output of the battery pack (10VAC, 7VA) and the approximate charge time (4 hours). There (...) (17 years ago, 12-Jul-07, to lugnet.robotics.rcx)

(...) Is the RCX still working? Does it "get hot" when it's running an unloaded motor? I would have thought that the 500 mA limit within the RCX case would prevent this, but perhaps it's marginal for some plastic piece "nearby". If the RCX is dead, (...)

One of my students accidently left a tied up gear train running for a while, i.e. In the midst of running a RCX, the case not only gets very hot, but also has a very strong plastic burning smell. At first I thought it is due to the stuck gear train, (...) (17 years ago, 11-Jul-07, to lugnet.robotics.rcx)

(...) Whoops, I missed that there was a third option. I concur with this, as it's both the right voltage and confirmed AC. The mA rating, BTW, is a capacity rating, so it will work for anything that draws 800mA or less. The NXT adapter is rated for (...) (17 years ago, 11-Jul-07, to lugnet.robotics.rcx)

(...) _ALWAYS_ assume DC on an actual power adapter (at least in the US). Most AC devices will just use a simple cord, like you'd find on a portable stereo. A handful of devices will need AC power in a non-standard voltage and will use DC-like power (...) (17 years ago, 10-Jul-07, to lugnet.robotics.rcx)
