The CNC E77 PRO is a cordless rotary tattoo pen machined from aircraft aluminum, built around a coreless motor with a 4.0 mm stroke and adjustable 5-12 V output. It ships with two 1600 mAh batteries that each run 3-5 hours and recharge over USB-C in about 2 hours, so one can charge while the other works. A color display shows and adjusts settings in real time, and it takes standard cartridge needles. It suits artists who want a quiet, low-vibration pen for long sessions without a cord; at 224 g it is heavier than many cordless pens, so balance and hand feel matter more than raw weight savings.
