What is the battery capacity and how long does it last? It features an 800mAh high-density battery paired with an efficient motor, delivering 4-5 hours of continuous use per charge — balancing compact design with reliable all-session power. How do I switch between voltage settings? Is it complicated? It's very simple. With the machine paused, just click the "+" (plus) or "-" (minus) key to cycle through the voltage modes. The LED display will show the current setting clearly, allowing for quick adjustments without interrupting your workflow. Is this tattoo machine suitable for permanent makeup (microblading, lip blush, etc.)? Yes, it's highly suitable for semi-permanent makeup. Its lightweight design and stable, low-power motor offer the precision and control needed for flawless eyebrow, lip, and eyeliner work. How lightweight is it, and is it comfortable for long sessions?
