Constructed with high-purity copper windings to ensure superior conductivity and minimal energy loss, this power supply delivers an impressive 98% energy efficiency. This design effectively eliminates any voltage drop during extended tattooing sessions lasting 10+ hours, providing consistent output. It incorporates a quiet cooling fan system operating at a low 30dB noise level, which actively dissipates heat to prevent overheating without disrupting the studio environment. The ergonomic aluminum housing features non-slip rubber feet that offer enhanced stability on various surfaces, along with a versatile mounting bracket for seamless wall or desk installation. This space-saving solution is particularly advantageous in busy studios, freeing up valuable counter space for artists to work efficiently.

Stable Performance: This unit maintains an exceptional ±0.1V accuracy across the full 1.5–18V range, which is vital for both coil machines—highly sensitive to voltage fluctuations—and rotary machines, ensuring precise control and reliable operation in diverse tattooing scenarios.
Nitro Boost Function: Engineered to improve tattooing efficiency, this feature delivers a temporary 1.5x voltage boost for precisely 0.5 seconds. This surge helps overcome initial skin resistance during the first passes, making it ideal for challenging areas like forearms with thick skin, reducing artist effort and enhancing ink penetration.
Longevity: Built for durability, the power supply offers a remarkable 10,000+ hour lifespan under normal use, supported by a comprehensive 5-year warranty that covers all components. This longevity outlasts standard power supplies by up to three times, providing a cost-effective and dependable solution for long-term use.
Ideal for high-volume tattoo studios and educational settings such as tattoo schools, where unwavering power consistency is critical for both professional applications and instructional purposes. The dual-channel design enables simultaneous operation of a liner machine (optimized at 9–12V for crisp lines) and a shader machine (best at 7–9V for smooth shading), significantly streamlining workflow.
It supports dual-channel control with 0–18V per channel, which can operate a liner machine and a shader machine simultaneously, streamlining the workflow.
It has a 98% energy efficiency with high-purity copper windings, which can eliminate voltage drop and maintain stable output during 10+ hours of extended sessions.
This feature can deliver a temporary 1.5x voltage boost for 0.5 seconds, helping to overcome initial skin resistance, especially suitable for tattooing thick skin areas such as forearms.
It has a 10,000+ hour lifespan under normal use, and is supported by a 5-year comprehensive warranty covering all components.
