The AVA UNI-B is a high-performance rotary tattoo machine engineered for precision, power, and reliability. Crafted from aircraft-grade aluminum, it combines lightweight handling with professional durability. Featuring a continuously adjustable stroke from 2.5mm to 4.5mm, a powerful 10,500 RPM AVA motor, and precision voltage control (0.1V increments or fast 1V adjustment), it adapts seamlessly to lining, shading, and color packing. The advanced timing function automatically starts when powered on and retains session data even after a battery change. A smart rebound system adjusts to skin resistance to minimize trauma and improve pigment implantation. The HD color display shows voltage, hertz, timing, and battery status at a glance. Powered by a replaceable 18500 lithium battery with circuit protection, the UNI-B delivers 6–8 hours of runtime for uninterrupted sessions. Designed for comfort and control, it includes a default 38mm anti-slip grip plus an additional 31mm grip, allowing you to customize handling to your preference. Powerful, precise, and fully customizable — built for artists who demand performance without compromise.
