The Mast A1 Pro is a wireless tattoo pen with a 3.5 mm stroke and a Mcore-A motor that runs at 12V and 12000 rpm. It has a screen showing voltage and power with 0.1V adjustments, a one-click liner/shader switch, and a 2200 mAh battery rated for about 13 hours of work. It can run cordless or plugged in. At 194 g and 33 mm by 124 mm it is a mid-weight pen aimed at beginners and artists who want one machine for lining and shading. Against rival pens it stands out for the on-body display and stroke that covers both lining and shading, but it is heavier than many slim pens and the single stroke limits fine detail work.

The Mast A1 Pro is a wireless tattoo pen machine with a 3.5 mm stroke. It uses a Mcore-A motor with a chip. The motor runs at a lower frequency at the same voltage, which gives beginners a smoother learning curve. Operation is controlled, stable and low in noise.
A screen shows the voltage and power level. Voltage adjusts in 0.1 V steps. The 3.5 mm stroke suits both lining and shading, and the pen has two modes to switch between liner and shader work. A gear transmission structure provides power with low vibration, low skin loss and fast coloring. Cartridges change and replace efficiently, and the machine is easy to cover and protect.
The pen can run cordless on its battery. It can also be used while plugged in for continuous power.
