2B Power Box

2B Power Box
2B Power Box


First launched at Erotica in 2010, it took over three years of initial development to come to fruition, and it is still improving with new beta firmware released on a regular basis. The 2B is now shipping with 2.106 firmware.

We continue to build on our E-Stim expertise and have created the most powerful and versatile E-Stim powerbox in our range. Officially called the Series 2B, or 2B™ for short, if you're looking for more power more control and more versatility then the 2B should be your only choice. Its also the only powerbox in the world offering secure control over the Internet using our new E-Stim Connect system*, and the only powerbox in the world to provide the ability to record and playback 'sessions' via Commander 3*.

Display & Control

The 2B has a clear backlit LCD display showing you exactly what your unit is up to all of the time, and with our enhanced display and control system it is even easier to use and gives you even more control than any other comparable unit. 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 option allows play in the darkest dungeon. Changing mode is simply a couple of quick button presses and knob twiddling. It's simple. It works.

More program modes

The 2B currently has 17 controllable and adjustable program modes. We have retained all of the popular functions of our previous Series 2, and 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.

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)

CommanderPC/Mac/Internet Control

The 2B has an optional Digital link Interface,which allows you to upgrade as well as control your 2B from a Windows PC or Mac, and even control your 2B from or across the Internet - all though a simple USB connection and our free Commander 3 software, and our award winning E-Stim Connect Service.


The 2B is upgradeable - No more out of date toys - Now your 2B can grow with your E-Stim experiences. With new modes and new functions on nearly every update, the 2B is only the beginning of your E-Stim experiences.

More powerful than ever

The 2B uses a single 9 V battery to generate fantastic levels of stimulation. The 2B has been designed with a with a highly efficient and controllable output system that offers multiple power settings so you can run in low or high power, and each power setting is controllable from 0 to 100%

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 an optional Universal mains power supply giving you around a 30% increase in power output as well as longer play times.

Warning the 2B is considerably more powerful than any of our other control units you have been warned.

AudioAudio system

If 17 program modes are not enough, the 2B is fitted with an adjustable sensitivity internal microphone (no external microphone to break off or loose) and offers true stereo audio processing, via a 3.5mm stereo input.

Designed to plug into the headphone socket of an MP3 or CD player, 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 pleasure.

Unlike other audio triggered stim units the 2B is designed to use normal audio sources as well more specialized 'stereostim' tracks, now available as a free download from https://e-stim.info/downloads/audio. Due to the fact most PCs and laptops no longer have CD drives, Audio CDs are no longer supplied.


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 UK, US and European safety standards, and carries UKCA & CE marks.

Lightweight and portable

The 2B is about the size of a paperback book. Slip it into a play bag, it's all you need for electro pleasure and torment.
