Actually, USB 2.0 is rated up to 1A. I'm using this:

My understanding is that they'll be charging twice as slow (so it's going to take twice as long to charge), but slow charge is supposed to be much better for the batteries (avoids overheating, etc)

I fried one PE when a no-name Chinese charger broke down. Then I bought another one with WSoD issue, hoping to replace the charging circuit, but it didn't work. Finally, I just got a third working PE, so now I have two non-working PEs.

That's nice, but I need something on-the-go, as I can be away from my car for several days.

I'm not familiar with this issue (links?) Do you mean that if you make PE run too hard, it consumes more current than the battery can provide?
