FK Irons – wireless tattoo machine Spektra Flux including 1x battery.

The PowerBolt Spektra Flux is the successor to the internationally popular Spektra Xion tattoo machine and the first wireless tattoo pen from FK Irons. It is driven directly, ie without suspension, and has a stroke of 4 mm. It is therefore suitable as a universal accessory for all tattoo styles.

The PowerBolt lithium-ion battery allows comfortable work without a power supply and cables. Battery replacement is quick and easy.

The PowerBolt battery lasts up to 10 hours and can be fully charged up to 1.5 A in a very short time via a USB-C connection. Thanks to the dynamic control of the power path, the battery can be powered and charged simultaneously. This means that even if the battery and, if necessary, the replacement battery are empty, you can continue to work with the USB-C cable. The PowerBolt battery is easily connected to a power source using a USB-C cable.

Spektra Flux also has a Bluetooth interface, through which the FK Irons hover power supply can be connected. You can also connect to an Apple or Android application via Bluetooth and update Spektra Flux at any time using the latest firmware.

In addition to the capacity and voltage LED display, the PowerBolt battery has three buttons: two buttons for setting the voltage and one button for switching on and off. The voltage can be set between 5 and 12 volts in 0,5 V increments using the two arrow keys.
