One Battery to Power Them All - FK Irons strives to develop products to revolutionize and innovate the tattoo industry. That’s why we engineered a powerful battery that’s not only well-balanced but can be universally connected to any RCA machine on the current market.

Connected to Any RCA Machine - This power supply has a compact design that is great for easy travel, and it keeps in mind the machine’s Ergonomic Balance Point. Ideal for the EXO and all RCA tattoo machines, NOT compatible with the Microbeau Bellar.

Small Yet Powerful Battery Life - LightningBolt Uni may be small, but can still power your machines for up to 10 hours, with just 1.5 hours of charge time. The LightningBolt Uni was designed to be the only power supply artists need and provide power for all.

USB-C Port Charging - Charge your PowerBolt in your car, laptop, or airport. This is perfect for the traveling artist or for trade shows. For charging voltage, simply decrease and increase voltage by half increments via two buttons.

LED Voltage Indicator - The Uni has only 3 buttons that allow you to check the battery, enable Bluetooth, increase and decrease the voltage, monitor the battery life, and turn off/on.
