Thank you for viewing. RICOH "AC-4 CN-4" This is a genuine RICOH AC adapter. It can be inserted in place of the battery in products that use the BJ-70 battery, allowing for long hours of continuous operation without worrying about the remaining battery level. It was stored after being used a few times. Operation has been confirmed. For safety, it will be cleaned with消毒用アルコール (disinfecting alcohol) before shipping.
