It took over 3 years to develop the first 2B, and it continues to feature regular updates to its software and accessories, resulting in one of the most powerful and versatile E-Stim power boxes available on the market today. Officially called the Series 2B, or 2B for short, if you are looking for more power, more control, and more options then the 2B is your only choice.

Display & Control

The clear backlit LCD display on the 2B shows you exactly what your unit is up to all of the time, 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, whilst 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 twiddle of a knob to choose 1 of 17 modes. It's simple. It works.

More program modes

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

Internet Control

The 2B is fitted with the hardware for a optional Digital PC link,which allows you to control your 2B directly from your Windows PC or Mac via a USB connection, and the free Commander software also offers computer to computer control over the internet.

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 its 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 in one and with the Triphase cable set, even more possibilities are available. (Think 3D Electroplay).

More powerful than ever

The 2B can be powered via single 9V battery, or an optional universal mains adaptor - the choice is yours. With dual power settings so you can run 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 whilst the high power setting offers really serious levels of output designed to satisfy the most ardent electrosex player, without causing too much pain!! and if the standard high power mode is not enough then you can connect the optional universal mains power adaptor (110V/220V) giving you around a 30% increase in power output as well as longer play times.

Warning the 2B is considerably more powerful than many of the units available today you have been warned.

Audio system

The 2B is fitted with an adjustable sensitivity built in microphone (no external microphone to break off or loose) and 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,(we even supply the cable) each audio channel is translated to a powerful controlled pulsing output. As an additional control it is possible to adjust the whole response of the audio processing system, providing a unique insight to stereo based E-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 from


With output channel isolation, built in power limiting and soft start controls (they always start at zero whenever you change a mode or switch the unit on), together with a design ethos that stresses safety at every stage the 2B has been designed to be compliant with all of the major US, UK and European safety standards, and carries a CE mark.

Lightweight and portable

The 2Bis small enough to slip into a play bag, it's all you need for electro pleasure and torment.

I like the fact that it can be plugged into the mains system. That saves on batteries. However, I also have an Electo Pebble and I like that better. It is easier to select a mode and to change the frequency and intensity. For some reason the 2B is more fiddly to set where you want it.

This box smokes compared to other boxes! All modes work as advertised. When you purchase one make sure you order the ac power adapter. Batteries are expensive and it gives more power for the experienced users. Wow!!!! It’s great. rPS

Excellent, worth every penny, sorry I wasted money on other similar products over the years, thinking they were all the same. So very wrong. There is absolutely a difference between the pricey play models and the cheaper work models. This specific model is easy to use with great effects.

not only is this an incredible unit, really incredible for my own use (for pleasure) and on my partners (for pain). But the support from the manufacturers is top notch! 100% worth the investment and I personally rate the extras too!

What an amazing little device that packs a lot of power! I got the accessory pack as well which I think was worth it. The sticky electrodes that come with it are far superior to the over the counter TENS pads too. Shipping was very fast with the UPS upgrade, I got it in four days delivered from the UK to west coast USA. I'm looking forward to discovering more!
