    I got this one once and it was never able to fully charge my batteries. Perhaps the device I was using the rechargeable batteries was to blame but this thing takes for ever and doesn't seem to work properly.

    I use one of these plugged in to my xbox, to charge the batteries i use in the controller. They charge up 1.2V nimh fine, but struggle with rechargeable alkalines at 1.5v. Either way It's a slow charge, but if you have a rotating set and use it in a similar manner as i do - you're never without a charged set.

    160mA charge rate, yeah that's pretty slow. You could probably hack this by jumpering out the existing charge circuit with a current limiting resistor to get it closer to the 500mA USB supports, but possibly not all 500mA and it might make the resistor hot enough to melt the plastic casing (I'm too lazy to do the math to figure it out but that's likely).
