FK Irons Spektra Flux Wireless Tattoo Machine - 2x PowerBolts, Chromium

The FK Irons Spektra Flux frees tattoo artists from cables and external power supplies, letting you work wirelessly across your entire session. Built by FK Irons and DarkLab, this pen-style rotary runs entirely from its detachable PowerBolt battery. This Chromium edition ships with two PowerBolts, so you can hot-swap a fresh battery mid-session and keep working without interruption.

Each PowerBolt houses a USB-C lithium-ion cell with Dynamic Power-Path Management, enabling simultaneous charging and power delivery. Runtime reaches up to 6 hours per charge, with fast charging at up to 1.5 A. Voltage is adjustable from 5-12 V in 0.5 V steps using the buttons on the PowerBolt, with an LED displaying both voltage and remaining capacity. A built-in killswitch prevents accidental power-on during transport.

The Flux connects to the DarkLab app via Bluetooth, giving you access to six e-give settings (0-5), wireless firmware updates, and pairing with the DarkLab Hover power supply. Its direct drive motor handles lining, shading, and colour packing with minimal vibration and low noise. The autoclavable grip can be steam sterilised at up to 132.2 °C / 270 °F between clients. Do not use an ultrasonic cleaner with this product.
