Hey i just bought my friends imp 350 off of him and its missing the ac adapter. Can anyone tell me the voltage and aperage that the OEM ac adapter is set for?? I have a rat shack ac adapter which looks like it will fit so i just need to find out the voltage and amperage the OEM ac adapter supplys. Thanks in advance for the help

The voltage and configuration of the plug are engraved into the unit itself, near the power plug. The voltage is 4.5v. mA doesn't matter.

The adapter iRiver supplied me is rated at 600 mA (4.5 V, center positive).
