Meet the MAST CIRCLE POWER SUPPLY, a compact and intelligent digital power unit engineered for professional PMU artists who value simplicity without sacrificing precision. With its clean, minimalist design and smart control system, the Circle brings intuitive, real-time power management to both PMU and tattoo work.

A bright OLED display sits front and center, giving artists instant, real-time voltage feedback for confident, accurate adjustments throughout every procedure. The one-touch rotary control makes dialing in the perfect voltage effortless — no complex menus, just smooth, immediate adjustment right at your fingertips.

One of the Circle’s standout features is its flexible operation modes, designed to match different artist preferences and working styles:

• Anti-fatigue Mode (b1) — Press once to activate continuous power, eliminating the need to hold the pedal down throughout long procedures. Perfect for reducing foot strain during extended sessions.
• Non-anti-fatigue Mode (b2) — Requires continuous pedal press for operation, giving artists who prefer traditional, moment-by-moment control the responsiveness they’re used to.

The Circle also supports both foot pedal and button operation, so artists can choose the activation method that best fits their technique and studio setup. Its Type-C power input ensures stable, universal connectivity — a modern, reliable standard that’s easy to source and travel with.

Compact and lightweight at just 157g with a footprint of 82 × 82 × 34 mm, the Circle is equally at home in a permanent studio or a mobile artist’s kit. It delivers a broad 4–15V output range, offering the flexibility needed for eyebrow, eyeliner, and lip procedures, as well as traditional tattoo work.

Whether you’re a beginner refining your technique or an advanced artist seeking dependable, everyday performance, the MAST CIRCLE POWER SUPPLY is trusted by professionals across the US, Europe, and global PMU and tattoo markets for its intuitive design, reliable power delivery, and studio-ready portability.
