Spark is the smallest PSU, slightly larger than a matchbox.
This model is made in a plastic case and is designed to work with one tattoo machine. At the bottom of the case are powerful magnetic feet that pull your PSU to any metal surface. I advise you to install these blocks specifically on metal work tables - in order to maximize all the stability gadgets.
The power supply will work with any tattoo machine with a suitable connector, no matter for tattooing or permanent makeup.
Please connect all our devices to high-quality network filters in order to eliminate the negative impact of voltage surges in your particular power supply of the salon or building.
