FK Irons ONE Wireless Tattoo Machine - Charcoal / Ruby

The ONE is a high-quality, reliable and affordable wireless tattoo machine for artists at all stages of their career, manufactured by the experts at FK Irons.

The ONE by FK Irons is powered by a rechargeable and replaceable Panasonic NCR 18500A battery, which provides 5-12V power for up to 8 hours depending on the voltage and needle module size used and can be adjusted in 0.5V increments.

The proprietary quarter-turn battery door opens easily, allowing for quick battery changes without any fiddly threading. The ruby-red cap also features a battery disconnect function—turn it counterclockwise to prevent unwanted power consumption. Batteries are charged via the included dual-slot eFest battery charger, ensuring you always have a spare on hand.

The simple display features a color-coded LED voltage indicator and is controlled by three simple buttons – two for increasing and decreasing the voltage, and one for turning it on and off. Half-steps are indicated by a flashing colored LED.

Made from medical-grade and aerospace-grade 6061 T6 aluminum, the ONE has a matte anthracite finish with a striking ruby-red end cap. The chunky handle has an ergonomic shape with larger grooves to prevent rolling and improve working comfort, and is compatible with all Cheyenne-type universal needle cartridges and modular FK handles.

The FK Irons ONE comes with a high-quality travel case with custom-made protective foam, making it perfect for guest spots and conventions. Its battery disconnect function prevents accidental activation during travel. It is available with either a 3 mm or 4 mm fixed stroke length – please select your desired stroke length.
