This is the latest addition to the JetPack Wireless line up. A recreated and upgraded version of the popular CNC wireless machine. The external designs are very similar but the internal parts are vastly improved with little to no price increase. The JetPack Hero is a completely wireless, battery operated tattoo machine. Operation voltage is between 5v-12v (increments of .5). Each 900mAh battery lasts 4-6 hours, depending on voltage levels during operating. Batteries attach to the machine magnetically to avoid connection issues as time passes and your machine ages. It has a 3.5mm stroke, making it the perfect machine for both lining and shading. The Hero features a coreless motor with continuous operation mode. Until powered down, the battery will remember all previous settings and start where you last left off. The JetPack Hero weighs approximately 176grams (6.2 oz). Extremely lightweight to prevent hand fatigue. 90 day warranty on all machines!
