I mistakenly bought this thinking it was a razor. Used a few times. The DOS-PTHC1-BK is a rechargeable hair clipper made by Van Pacific International Trading Co., Ltd. It is a product sold under Don Quijote's private brand, "Jonetsu Kakaku" (Passionate Price). Charging/AC adapter: Can be used while charging. Charging time: 8 hours. Applicable adapter: ZDJ030060JP. DC IN: 3V. Operating time: Approximately 45 minutes on a full charge. Regarding the applicable adapter (ZDJ030060JP) Manufacturer: The genuine adapter for the Doggy Man pet clipper "Home Barber" series also uses this model number (ZDJ030060JP). Thank you for looking.
