I don't have any sort of MP3 player and I'd like to use my Sony Reader to listen to music or audio books in my car. While I am completely satisifed at how long the battery lasts between charges when reading books, it seems that playing audio burns through the battery much quicker. As such, when I use the Sony Reader in my car, I'd like to plug it into the cigarette lighter. Sony sells an accessory (Car FM Stereo Transmitter DCC-FMT50U) that will allegedly both transmit the signal from the Sony Reader to a selectible FM frequency to play over the car's speakers and allow the Sony Reader to be charged. The charging comes via a USB connection on the device. The specification for the device states that its output is 5.0 VDC at a maximum of 500 mAmps. The AC device that comes with the Sony Reader states that its output is 5.2 VDC at a maximum of 2000 mAmps. Also, this cigarette lighter device is not specifically listed as compatible with the Sony Reader.

I'm not worried about the difference in amperage output, but does anyone know whether the difference in voltage (5.0 VDC vs. 5.2 VDC) represents a problem? I'm thinking that because the connection to the cigarette lighter device is via a USB connection, it should be OK.

But if anyone has a better understanding of this, I really appreciate your thoughts.
