TENS Unit Pain Relief Device

This TENS unit is battery-powered and small enough to clip onto a waistband, which is the point of a portable design — it's meant to be worn through normal daily activity rather than used only while sitting still. The unit runs on two AAA batteries rather than a proprietary rechargeable pack, so replacements are easy to find anywhere.

It offers multiple preset modes along with a manual intensity dial, giving a range from a very light setting up to a stronger one, adjustable in small increments rather than a few fixed steps. The dial has a tactile click at each increment, so the intensity level can be adjusted by feel without needing to look at the unit.

Two dual-lead wires connect to four self-adhesive electrode pads, which is enough to run two separate placement zones at once. The pads are the reusable gel type, and the kit includes a spare set so the first pair can be replaced once its adhesive wears down from repeated use.
