Sadly, no. It seems that in order for the device to accept a charge by USB it needs to be attached to a computer. I bought an inexpensive USB charger for the PSP from amazon (it has a usb plug on one end and an AC plug on the other) and it works great from a USB brick (I use one I have for my iPod). The cable I got also has a 5-pin mini USB plug so I can use it as a data cable, too. (Your motorola connector is probably a 5-pin mini USB, micro USB wouldn't fit a Sony Reader.)
