Chrome-plated cutting set with "Crunch Blade" technology. The staggered teeth guide the hair more quickly to the cutting set, provide the user with acoustic feedback, and create soft transitions. Lightweight, cordless design for comfortable handling combined with the usual strong cutting performance of Wahl's corded hair clippers. Highly efficient and durable lithium-ion battery with no memory effect. 90 minutes of runtime and 120 minutes of charging time.
