PowerBox Comparision

Too much choice

We have now created a E-Stim Systems powerbox comparison chart. This allows you to scan through all of our power units and select the one most suited for your needs, based on a number of criteria. If this proves popular, we may even extend this to other non E-Stim Systems power boxes.

Size

Size of a powerbox is always a concern, there is no point looking for an E-Stim unit for discreet use, if it is the size of a brick, but if a powerbox is too small, then the controls might turn out to be too fiddly.

Outputs

The number of outputs determine how many electrodes you can control at any one time. Isolated outputs allow you to control an electrode without any interaction with another electrode, especially important if you are playing near the chest. Why do we not give a specification for the actual output level? Because firstly no other competitor releases such details, and how powerful a box feels is highly dependent on the waveform and position of pads etc.

Display

A clear display helps you understand what your powerbox is doing at any one point, the more complex the unit, the more you will need a comprehensive display. Being able to see the display and controls in the dark is obviously useful.

Modes

Different and refined program modes is what makes an E-Stim unit exciting, and breaks away from the more static TENS style modes. Audio Modes allow you to use sound to generation sensation, Motion modes allow you to create sensation from movement. Triphase mode makes things go all 3D.
