RE-ENGINEERED FOR ELITE PERFORMANCE

Reimagine your daily driver with maximum control and premium tech.

The FK One Update builds on the most trusted elements of its predecessor and refines them into a true all-rounder for working artists. Designed to stay in your hand from first line to final pass, it removes the need to switch machines mid-flow—delivering consistent performance across lining, shading, and packing in a single platform.

Extend your sessions with upgraded dual-battery performance and clear digital control.

Dual rechargeable battery compatibility (18500A & 18650A) gives you extended runtime and flexible power options, delivering up to 5.5–6.5 hours of power, depending on your settings. An upgraded and refined 1.1” LCD display keeps your voltage and system settings immediately visible, giving you precise, at-a-glance control without interrupting your workflow.

Reduce fatigue with refined ergonomics built for real studio demands.

At just 215g (233g with battery), the FK One Update is engineered for balance, control, and long-session comfort. Its streamlined body integrates directly with Ergo Shield grips for faster setup and a more stable, natural hand position—helping reduce strain while maintaining full control over detail-heavy work.

Available in 3.0mm and 4.0mm fixed stroke configurations, the FK One Update is tuned for dependable performance across core tattooing techniques. With a 5V–12V (80Hz–180Hz) operating range and precise incremental adjustments, artists can fine-tune machine performance to match their technique, workflow, and client skin response in real time.
