Description
Introducing the new K250-4S E-Stim Power Box by Kink!
Phone sized touch screen offers a large, user friendly interface that makes this power box a breeze to use. Four independent channels with accompanying stick-on electrode pads can provide customized stimulation where you choose. Balanced (bipolar) wave forms work independently, or link the same waveform across multiple channels to make your e-stim experience exceptional.
