you're right.

all chargers are dumb.

it is the reader that controls charge current. and monitors battery temperature. otherwise it would explode.

but some chargers are so dumb (i.e. non-standard) that the reader does not recognize if it supports hi speed charging (i.e. current >500mA). (for this to happen, there has to be 0...200Ohm resistance between usb data pins).

there are some reports in the forum that a charger with at least 1000mA results in longer battery life.
