This is a Braun Series 9 (S9) type 5790 electric shaver. It's a popular Series 9 model. The model number is likely 9250cc. The set includes the main unit and AC adapter. It is a used item and has minor scratches from use. * The blades are partially torn, so please consider them as a bonus. * In my personal opinion, the sound seems a bit loud with the current blades installed. Number of blades: 4-blade Drive system: Reciprocating Power supply: Rechargeable, AC Washable With trimmer 5790 Type...Men's electric shaver/beard trimmer Popular series...Series 9 12
