This pair of adapters will allow a 3.5mm Folsom or Erostek accessory to plug into power units with a smaller 2.5mm output jack.
Folsom and Erostek power units typically have a 3.5 mm output jack. European made Rimba toys have smaller plugs than our American made boxes. This in-line adapter will allow you to use Rimba Accessories with the Folsom or Erostek electrostim units.
You will need an adapter for each plug on the accessory that you plug into the base unit. We also have the 3.5mm to 2.5mm adapters.
