I've had a 1000 since launch that's been on M33 5.00_6 for ages, which I love having it at, but I got sick of all the trouble it takes to make new UMDs work, so I gave up and got a new 3000 to leave on OFW for playing new stuff on.

Anyway, the power cords are different, and I can't tell if it's ok to use one with the other, to avoid having to carry both around. They're both 5V, but the new one is 1.5A while the old is 2A. My limited knowledge of electricity says that just is the output speed, so using the 1.5A on the old system should be safe, just slower charging. Is that right?
