Ambition Mars-U Wireless Tattoo Machine Kit — Adjustable Stroke, 1800mAh Battery, 40 Cartridges

Experience cordless versatility with the Ambition Mars-U Tattoo Kit

Switching to wireless power brings freedom to work from any angle without cables getting in the way. The Ambition Mars-U kit combines a space‑grade aluminum body with a reliable coreless motor, delivering smooth performance up to 9000 RPM across a voltage range from 5 to 12V.

Six stroke lengths are available—2.2, 2.6, 3.0, 3.4, 3.8, and 4.2 mm—and can be adjusted on the fly with a simple dial. This makes the kit suitable for soft shading, color packing, and crisp lining, all while maintaining balance in the hand during longer sessions. The lightweight, durable frame is crafted for daily studio use or on‑the‑go work, with a compact profile that still feels substantial in action.

What’s included in the kit

• 1 wireless tattoo machine and 1 additional battery for extended cordless work
• 1 charging cable and 1 RCA adapter plus silicone RCA cord for flexible setup
• 40 tattoo cartridges split into 20 RL and 20 RM with safety membranes and sterile packaging
• 20 ink cups, a bandage, gloves, a pen bag, a practice skin, a zipper box, and a large travel suitcase

Material and build

The machine body uses space‑grade aluminum alloy with CNC precision. Measuring 137 mm in length and 32 mm in diameter, it weighs about 217 g—an ergonomic balance designed for steady control during extended sessions. The device supports 6 adjustable strokes and remains compatible with most cartridge needle types.

Power, display, and practical use

The 1800 mAh battery powers longer sessions, and the built‑in LCD shows remaining power, the operating voltage, and estimated run time. A full charge typically takes around 2 hours, and an 8V output can sustain roughly 6 hours of operation under typical use.

How it fits your workflow

Designed for flexible setups, the Mars-U kit enables freedom from cords, which can streamline movement and reduce drag during sessions. The 40 cartridges provide a range of options for different textures and line work, while the included practice skin supports safe, hands‑on rehearsal before real client work.

Operational essentials

Power on by holding the O button for a few seconds. Pause or resume output with quick presses, and adjust voltage in 0.1V steps using the plus and minus controls. Fast charging is supported with the appropriate cable, and the LCD keeps you informed throughout a session.
