E-Stim Systems 2B Power Box

About E-Stim Systems

With everything from E-Stim, you are not just buying a box or electrode, you are purchasing a serious introduction into the E-Stim world, from a company that is dedicated to producing the best in electro-stim technology.

Lifetime Warranty

All E-Stim Systems control units and premium electrodes are now covered by a LIFETIME GUARANTEE. In other words, if it fails in reasonable use, within your lifetime, and you are the original purchaser, they will endeavor to repair or replace the product free of charge. Shipping and handling fees may still apply.
Display & Control

The clear backlit LCD display on the 2B shows you exactly what your unit is up to at all times, with an enhanced user friendly display and control system making it easy to use and giving you even more control. There is no need to learn any funny codes or count flashes. A built-in help display guides you through mode selection, while the back light options allow visibility in the darkest dungeon or play space. Changing mode is simple - A couple of quick button presses and the turn of a knob to choose 1 of 17 modes. It's simple and it works.

More Program Modes

The 2B has 17 fully adjustable program modes. With all the standard E-Stim modes present, they have added some new ones so you can now throb and thrust your way to electro-stim ecstasy and pleasure. Split modes, tickle, and programmed wave functions all pack the 2B with hours of electro-stim pleasure - and since the 2B is upgradeable (see Accessory Pack below), you can add new modes and functions when they are released.

Dual Isolated Channels

The 2B features two completely isolated output channels, with independent controls on each channel. This allows you to use multiple bipolar electrodes at the same time, and be able to control them both, independently. The output LED's light up in proportion to the output levels so it’s possible to see what's going on without consulting the main display. With the join mode it is possible to join both channels together, giving safety and control one channel.

More Power

The default 2B Power Box is powered via single 9V battery. With dual power settings, you can run this box in low or high power, and each power setting is controllable from 0 to 100% in 1% steps. Low power gives an excellent introduction to E-Stim while the high power setting offers really serious levels of output designed to satisfy the most ardent electro-sex player, without causing too much pain.

If the standard high power mode is not enough then you can use the optional 2B Power Supply Cord (sold separately), giving you up to a 30% increase in power output as well as longer play times.

Warning: the 2B is considerably more powerful than many other standard power units. This box is perfect for guys that need more juice!

Audio System

The 2B is fitted with a built-in microphone with adjustable sensitivity. The 2B also offers true stereo processing, via a 3.5mm stereo input. Designed to plug into the headphone socket of an MP3 or CD player (cable included), each audio channel is translated to a powerful pulsing output that's controlled by the beat of the music. As an additional control it is possible to adjust the whole response of the audio processing system, providing a unique insight to stereo based electro-stim.

Unlike other audio triggered stim units, the 2B is designed to use normal audio sources as well more specialized E-Stim audio tracks, available as free downloads here.


The 2B Power Box has several safety features:
  • A design ethos that stresses safety at every stage.
  • Output channel isolation.
  • Built-in power limiting and soft start controls - power channels always start at zero whenever you change a mode or switch the unit on.
  • Compliant with all of the major US, UK and European safety standards, and carries a CE mark.
