Thank you for viewing. This is a Panasonic SD camera AC adapter, model SY-AD10. - Brand: Panasonic - Model: SY-AD10 - Type: AC Adapter - Application: For SD cameras - Included items: Instruction manual Although it is unused, it has been stored for a long time, so I have classified it as "like new." Reference: Input: 100V Output: 4.5V 800mA It should be usable with other devices if the plug and output voltage match.
