Universal ROVER R-1 - Tattoo Battery Pack

One battery. Every machine. Zero downtime

The ROVER R-1 Universal is a wireless battery pack built to power virtually any rotary tattoo machine, with the same rock-solid output from the first line to the last. When a cell runs low, swap in a fresh one in seconds and keep tattooing.

Up to 15 hours of work per cell. Designed and made by MUSOTOKU in Madrid, Spain.

Why artists choose the ROVER

• Constant power, start to finish. The voltage you set is the voltage you get, at 100% or 5% battery. No fading hits at the end of a session.
• No proprietary batteries. It runs on standard 18350 Li-ion cells available worldwide. When a cell wears out, replace the cell, not the whole battery pack.
• Never stop mid-session. Two cells are included, so one charges while you work.

• Fits your machines. It connects natively to Critical/Bishop-style machines, and adapters cover FK Irons, RCA and Cheyenne.
• Smart protection. It checks your machine over 1,000 times per second to detect [qué detecta] and keep everything running smoothly.
• Brushless-ready. A dedicated soft-start sequence protects sensitive brushless motors.
• NITRO Jumpstart. A short power boost on start-up gets your machine running instantly, even at low voltages. You can switch it on or off.
• Compact and tough. Machined from aerospace-grade aluminum, it weighs just 72 g with the cell inserted.

FAQ

How long does a cell last?
It depends on your machine and voltage. Expect 10–15 h with a Mercury M-1, or 6–8 h with a Power Wand 1st Gen. Higher voltages and more demanding machines use more power.

Can I fly with it?
Yes. Take the cells out of the battery pack and carry them in their original plastic case, in your hand luggage. Don't travel with a cell inside the battery pack.

Can I use other 18350 cells?
Yes, absolutely. Any good-quality rechargeable 18350 Li-ion cell with a flat top will work, so you can buy spares wherever you are.
