Which one should I use? I am hoping the AT&T but the 800mA makes me a (...) (17 years ago, 10-Jul-07, to lugnet.robotics.rcx)

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)

| | | | | | (...) 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)
