Adaptation to your technique

The 4 – 12 V (66 – 199 Hz) range allows fine-tuning based on your working style. The lowest setting is ideal for techniques such as dotwork, while higher levels provide enough power for lining and shading.

Adjustment in 0.1 V or 0.5 V increments gives you a level of precision that is often not available with standard equipment.

Powerbolt II and full control

The Powerbolt II battery features a digital OLED display designed for maximum intuitive control. It allows all values to be adjusted directly on the device without the need for an app.

The display also includes a flip-screen function, so all values remain easy to read regardless of which hand you use or the working position.
