The PCH Digital Pulse Massager 3 AB offers a battery-operated muscle stimulation system that helps to relieve minor muscle aches and pains. This pocket-sized pain fighter features multiple settings and modes, a compact design, and a rechargeable internal lithium battery. The unit also features a brightly lit LCD screen for easy reading. The different massage modes and soothing haiku mode stimulate tense and sore muscles by sending pulses through the included electrode wires and adhesive pads. The massager’s AB feature also allows for ultimate control—each of the 2 output channels can be on different settings at the same time.
