The AVA UNI-B is an ultra-versatile cordless tattoo machine, designed to meet the needs of both beginner tattoo artists and experienced tattoo artists looking for a high-performance, scalable, and reliable machine at an accessible price. Made from aerospace-grade aluminium, it offers excellent robustness while remaining lightweight and perfectly balanced, weighing only 190 g without the battery, ensuring a comfortable grip and precise control even during long sessions.

Its main advantage lies in its continuously adjustable stroke from 2.5 mm to 4.5 mm, without predefined increments. This extremely precise adjustment range allows the machine to be instantly adapted to all tattooing styles, from fine lining to soft shading, including filling and dotwork. This flexibility makes it an ideal machine for performing different techniques and working on various styles with a single machine.

Equipped with a high-speed AVA motor of 10,500 RPM, the UNI-B delivers stable and responsive power, allowing for easy needle penetration at low voltage for smoother and more skin-friendly work. Its integrated rebound system automatically adjusts the needle return based on the skin's resistance, reducing skin trauma and improving comfort for both the client and the tattoo artist.

The UNI-B machine features a high-definition colour screen that clearly displays the voltage, frequency, battery level, and working time. Its timing function starts automatically upon power-up and retains the data even during a battery change, providing precise session tracking. The voltage adjustment is simple and intuitive, with fine adjustments of 0.1V or quick adjustments of 1V according to your needs.

The AVA UNI-B has a brand new feature for its high-definition colour screen, it's a true assistant. The screen changes colour according to the voltage used, allowing you to visually identify the settings in an instant: green (4.5v-6.9v), blue (7.0v-8.9v), orange (9.0v-10.9v), and red (11.0v-12.0v).

Operating with a new-generation interchangeable 18500 lithium-ion battery, the UNI-B offers a comfortable battery life of 6 to 8 hours, ideal for long workdays. When the battery is low, the Lightning icon flashes to remind you that it's time to recharge. This feature is simple but essential, ensuring that you never run out of battery during a session. Its improved protection circuit secures the machine even in case of incorrect battery insertion, enhancing its durability. Its non-slip and ergonomic grip ensures excellent stability and reduces hand fatigue, even during extended sessions.
