FK Irons’ ONE is powered by a rechargeable and replaceable Panasonic NCR 18500A battery, offering 5-12 V of power for up to 8 hours - depending on voltage used and cartridge size - with adjustments in 0.5 V increments.

The proprietary quarter-turn battery hatch is easy to open, allowing you to replace the battery quickly with no fiddly threading system. The ruby cap also has a battery disconnect feature - turn the cap anti-clockwise to prevent unwanted power use. The batteries are charged through the supplied dual slot eFest battery charger, meaning you can always have a backup battery ready and waiting.

The simple display has an LED colour-coded voltage indicator and is controlled by three simple buttons - two for increasing and decreasing voltage, and one to turn the power on or off. Half increments are indicated with a flashing coloured LED.

Manufactured from medical- and aerospace-grade 6061 T6 aluminium, the ONE comes in a matte charcoal finish with a distinctive ruby end cap. The chunky grip has an ergonomic shape including larger grooves to prevent rolling and enhance comfort while working, and is compatible with all universal Cheyenne-type cartridges and modular FK grips.

The FK Irons ONE is supplied with a high-quality travel case with custom-cut protective foam, making it perfect for guest spots and conventions, and with the battery disconnect feature it won’t accidentally turn on while travelling. It is available with either a 3 or 4 mm fixed stroke length - please select the stroke length you require.
