ET71 Tattoo Gun

The ET71 introduces a revolutionary, patent-protected feature: an independently swappable battery module. It grants tattoo artists something rarely offered-true creative freedom, untethered and uninterrupted.
Unlike conventional machines that require twisting or unscrewing the upper body to change batteries, the ET71 supports hot-swapping. The battery module is completely independent from the rest of the machine. A single push slides it out; three seconds later, a fresh one slides in. Artists can do this one-handed, without putting the machine down, and even with gloved hands. The result is a level of workflow fluidity previously unavailable in tattooing.
Each 1300mAh module delivers over eight hours of continuous use. With a two-module rotation strategy, work stops for nothing. No downtime. No interruptions.
The body is precision-machined from aluminum alloy, strong, yet lightweight. The material’s natural damping properties effectively absorb high-frequency motor vibrations, significantly reducing hand fatigue over long sessions. Its high rigidity ensures perfect coaxial needle movement, translating to consistent saturation and precise puncture depth.
Stroke length is adjustable from 0 to 4mm, covering both lining and shading modes. The ET71 adapts to a wide range of techniques, fine line, soft gradient, stippling, and beyond. An LED digital screen displays key parameters in real time: battery level, voltage, frequency, and operating mode. A dynamic breathing pattern pulses on the screen, changing rhythm with the frequency. Shortcut buttons allow quick access to memory mode switching, output voltage toggling, start and stop control. Three programmable memory modes allow users to preset different voltages for workflows, switching seamlessly between them.
