AVA Uni-K Wireless Tattoo Pen Machine

The AVA Uni-K is a fully adjustable, feature-rich wireless tattoo pen machine designed to adapt to any tattoo style. Crafted from aircraft aluminium and powered by a brushless motor, it delivers consistent performance with minimal vibration and wear thanks to its direct drive system.

A standout feature is the internal adjustable stroke system, allowing you to set the stroke length anywhere between 2.5mm and 5.0mm. This makes the Uni-K highly versatile, from fine line work at shorter strokes to bold colour packing at longer ones. Adjustment is simple using the included tools.

The AVA Uni-K offers two torque modes for greater flexibility:

• High torque mode (H) – provides strong, consistent penetration for crisp line work
• Low torque mode (L) – offers smoother action, ideal for shading and gradients

Artists benefit from the OLED HD colour screen that clearly displays voltage, frequency, timing, memory settings, and Bluetooth connectivity. The timing function automatically starts when powered on and retains data even when changing batteries, while the memory function allows you to save up to four custom voltage settings.

With a 1600mAh battery, the wireless AVA Uni-K machine offers up to 7-8 hours of runtime depending on voltage. Each tattoo pen comes with an extra battery and an additional grip, giving you more flexibility during long sessions. Bluetooth compatibility means you can also pair it with the AVA foot pedal for wireless control.
