TENS Unit Muscle Stimulator Charger - Mini USB Cable for Pain Relief & Recovery - Portable EMS Device for Home, Gym & Physical Therapy

I was cleaning out old wires a while back and must have tossed the one that went to my device I use to stimulate achy shoulders. So I saw this one on Amazon and thought I'd give it a try. It works great to charge up the device. Don't use it often, guess that's why I didn't realize I'd tossed the old cord. But I'll be sure not to toss this one!
