genuine PSION AC Adaptor Class 2 Transformer for use in USA with Psion
Never used
Model number appears to say MODEL D350900200U but the "D" might be an "O" as I can't read it clearly! See photo.
I bought it in case I travelled to USA with my Psion but I didn't end up ever needing it so it has never been used and is effectively a New unused product in its original box which has markings on it in pen.
