This is a used Panasonic rechargeable shaver. I purchased it approximately 35 years ago. It can be charged with 240V to 100V. I think the usage time is not much as I only used it when traveling. It can be charged and used, but please purchase it as a collector's item, as there is a possibility of aging deterioration of the rechargeable battery and circuit components. - Brand: National Panasonic - Model Name: ES845 - Power Supply: AC100V-240V 50-60Hz 4W - Charging Time: 1 hour - Function: Rechargeable shaver The outer and inner blades are used.
