The Therapy TENS Unit 4 is a fourth-generation, wired TENS muscle stimulator with a touchscreen and a 6000mAh battery. It offers 20 intensity levels, and the maker claims the output is strong enough to reach deep muscle and nerve level, unlike most wireless units whose small in-pad batteries limit power. It suits people with chronic or stubborn pain who want a simple, high-output home device and prefer a screen over dials. Against budget TENS units it stands out on battery capacity and interface; against wireless pads it trades the cable-free convenience for more current.
