The FK Irons PowerBolt II is a next-generation wireless battery module, developed to power Flux Max, Flux and EXO machines from FK Irons with greater control and consistency.
It features a digital OLED display with a dedicated menu that allows you to adjust voltage between 4–12 V, in steps of 0.1 V or 0.5 V, and view information in volts or hertz according to the artist’s preference.

The internal electronics of the FK Irons PowerBolt II use an advanced motherboard that adapts in real time to the working style, optimising power delivery based on skin resistance, needle setup and working speed.
The module also allows you to configure eGive in different levels (0–3), adjusting the feeling of hit to behave more like a coil machine or a firmer, more direct response.

The FK Irons PowerBolt II includes Bluetooth 5.0 connectivity, compatible with accessories such as the Darklab Killswitch, and supports firmware updates via the Darklab app, ensuring the system stays up to date without the need to replace hardware.
In real use it provides around 5–6 hours of battery life per charge (depending on voltage and setup), with fast USB-C charging in approximately 2 hours, keeping the wireless setup simple and efficient in the studio.
