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-grade 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, which allows you to set the stroke length 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 lets you save up to 4 custom voltage settings.

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

What if it's not right when it arrives?

Tell us as soon as you spot a problem and we'll put it right with a repair, a replacement or a refund. Our terms explain how to make a claim.

Can I spread the cost?

Yes. You can pay in three with either Klarna or PayPal at checkout. Your total is split into three interest free payments: one when you order, then one a month for the next two months.

Both run a quick check and decide at checkout, so it is not offered on every order. PayPal Pay in 3 needs a basket between £30 and £2,000. Klarna charges a fee if a payment is more than 14 days late; PayPal does not.

Do I earn points on this order?

Yes, as long as you have a Magnum account. You earn a point for every £1 you spend, and they're added once your order has been sent. Save them up for money off a future order.

How do I track my order?

As soon as your order leaves us, we'll email you a tracking link so you can follow it all the way to your door. Order before 4pm on a weekday and it goes out the same day.

Magnum have always been a solid supplier for all my tattoo equipment needs, nothing is ever too much trouble!! It's always super cool knowing they're a small family owned business who always look out for their customers. Would highly recommend to anyone, even non tattooists as they do a great aftercare selection!!
