Complete guide: External battery pack FK IRONS AIRBOLT MINI white
Airbolt Mini is an external battery (portable power supply) by FK Irons, designed for artists who want to ditch the long cable to the fixed power source and work freely, without wires hindering arm movement. It connects to the tattoo machine via a standard RCA cable and can be controlled either directly from the battery or wirelessly via Bluetooth from the Darklab app, where you can save voltage presets. With intuitive controls, LED display, and integrated non-slip magnetic pad, it's designed for portability — useful both in the studio and at events or conventions where you don't always have a plug nearby.
How to use
- Charge the battery fully before first use, using a USB-C cable.
- Connect the battery to the tattoo machine via a standard RCA cable (cable not included in the package).
- Secure the battery on a nearby metal surface using the built-in non-slip magnetic pad, so it does not move during work.
- Turn on the battery and adjust the output voltage (range 5–12V, in 0.5V steps) directly from the LED display, as with any classic power supply.
- Optionally, pair the battery with the Darklab app via Bluetooth for wireless control and to save voltage presets in Preset Bank, quickly reusable between sessions or clients.
- Monitor the charge level on the display during work; the battery has automatic protective shutdown when the charge level drops below 3%.
- At the end, recharge the battery via USB-C — it supports fast charging speed up to 1.0A — preparing it for the next session.
- Store the battery in a dry place, away from extreme temperatures, when not used for an extended period.
Tips from us
- Always keep a spare battery charged for long sessions, so you can quickly swap without interrupting your workflow.
- Use the presets in the Darklab app (Preset Bank) to instantly return to your preferred voltage for each technique, without manual adjustment every time.
- Do not leave the battery completely discharged for long periods between sessions — like any Li-Ion battery, it wears over time and capacity gradually decreases with use.
- Periodically check the condition of the RCA cable and connectors, for good contact and stable power to the machine.
- Clean the battery casing between clients carefully, without letting liquid seep into the USB-C port or the RCA connector.
Frequently asked questions
Which tattoo machines is Airbolt Mini compatible with?▾
According to the manufacturer's description, it is compatible with FK Irons machines and most other rotary machines, connecting via a standard RCA cable (cable not included in the package). If your machine uses a different type of connector, check before purchase if you need an RCA adapter.
How is it charged and how long does a full charge last?▾
The battery is charged via USB-C, with fast charging speed up to 1.0A. The operating time stated by the manufacturer is approximately 10 hours, but this may vary depending on the voltage used, needle type, and working conditions.
What is the Darklab app and is it mandatory?▾
Darklab is the FK Irons app through which you can control the battery wirelessly via Bluetooth and save unlimited voltage presets in Preset Bank. It is not mandatory — the battery also works controlled directly from its own display — but it offers added convenience for artists who work with multiple fixed settings.
How do I care for the battery between clients, from a hygiene perspective?▾
Being a reusable electronic device, it cannot be sterilized in an autoclave. Cover it with disposable barrier film before each session, change the film between clients, and avoid direct contact with liquids, especially around the USB-C port and RCA connector.
What output voltage does it offer and how do I adjust it?▾
The output voltage is adjustable in the range 5–12V, in 0.5V steps, directly from the battery's LED display or from the Darklab app if connected via Bluetooth.
What happens if the battery fully discharges during a session?▾
The battery has an automatic protective shutdown function when the charge level drops below 3%, to avoid complete discharge. The practical recommendation is to always have a spare charged battery for long sessions, so you can continue without interruption.
