Polly,

I suspect you're fortunate in having cables kicking around that actually worked. Perhaps all micro-USB power cords work fine. I don't have any other devices in my collection of gadgets, that charge from micro-USB, so I have been testing what happens when I plug the cord that came with my 650, into a variety of generic USB chargers. And my results have been the opposite of yours. So, yup, still confusing.

Here's what I posted in an earlier thread:

I have a Griffin USB wall charger I use to change my Sansa MP3 players, but it didn't work with my PRS650. The specs on this say it is 5v, 1000mA.

Neither did my Belkin USB car charger - the PRS650 saw it as USB, but didn't kick over to charge mode. This one is labeled 5v, 1A output with a 12v input. The cig lighter port I had it plugged into would have been putting out a little over 12v, because that's what motorcycles do, but I wouldn't think that would matter.

The USB port on the Alpine stereo in my truck didn't even look like USB to it, it was like it wasn't plugged in at all. I have no idea what specs that port puts out, but the stereo was on so you'd think it was live.
