FK Irons ONE - Charcoal 3.0

The FK Irons ONE is powered by a replaceable Panasonic NCR 18500A battery, offering: 

• Voltage range of 5 to 12 V, adjustable in 0.5 V increments. 
• Up to 8 hours of operation, depending on voltage settings and cartridge size. 

The patented quarter-turn battery slot enables quick and hassle-free replacement without tedious unscrewing. Additionally, the ruby end cap with a battery disconnection system prevents accidental activation during transport. 

The machine features a clear LED display and three simple buttons: 

• Two for voltage adjustment. 
• One power button. 

"Half-step" voltage values are indicated by a flashing light, ensuring precise control. 

Crafted from aluminum, the ONE has a sleek matte Charcoal finish with a distinctive ruby end cap. 

The ergonomic grip with deep grooves ensures a secure hold and prevents the machine from rolling on the table. It is compatible with most universal cartridges and FK modular grips.
