How does the Vader ST3778 deliver professional cutting power?

At the core is a 7000 RPM motor tuned for steady, snag-free cutting that handles coarse or fine textures. The motor’s torque supports clean passes without pulling, while the DLC-coated T-blade stays sharper longer and resists wear.

• 7000 RPM motor optimized for smooth, consistent cutting.
• Zero-gap DLC T-blade for precise edge work and minimal friction.
• Designed to cut through varied hair types without frequent blade changes.

What makes the battery and charging system practical for long sessions?

The integrated lithium pack provides up to 210 minutes of cordless runtime per full charge, so a single charge covers multiple clients or extended personal grooming routines. Fast USB-C charging and a dedicated dock keep the trimmer ready, while the LED battery display shows remaining power at a glance.

• Up to 210 minutes runtime—enough for several full sessions.
• USB-C fast charging plus included charging stand for convenience.
• LED display gives clear, real-time battery information.

• Ergonomic shape reduces strain during long grooming sessions.
• Kit includes 3 guide combs, cleaning brush, oil, and blade guard for precision and upkeep.
