This is a powerful little bullet-type power source. It is special in that it can give power through a cable to an accessory, or be a bipolar power all by itself in your hand for a truly unique massage. It's approximately 4in x 2in and uses a round 3V battery (included).
It uses a 2.5 jack input for the leadwires, a standard 2 pin lead is included with your purchase. You can add on an additional 4pin lead at half the normal price if you choose.
*All power sources come with one 2-pin leadwire per channel, and 1 sheet of pads. Standard will be 50mm square, if you prefer something else please enter it in the notes section of checkout and we can make the substitution.*
