2B Power Box


I discovered eletrostimulation with the 2B a few months ago and I must say it is close to perfect !

Lots of different modes, powerful enough (I would recommend buying the power cable, the battery is little too weak imho), cleverly designed (the buttons are operatable with one hand) ... and most of all, reliable !

I recommend it wherever i go ;)

Wow, what can I say about this little box of tricks? I have been a 2B owner for over two years, and it never fails to surprise and delight me, in fact I am STILL working my way through pattern/power combinations! Negatives? The backlight is too bright, and I have gone through two power packs, so use it with batteries only now. Nonetheless, I thoroughly recommend purchasing one!

Have had my Series1 EStim for about a month now the Series 1 is a great starter machine, Simple to use and packs a real punch which is now left at my ladies home for when I am over there.
So for Christmas I treated myself to a 2B EStim as the reviews said it had more kick than the series one, Well I can say that I am truly impressed with the 2B machine and yes the 2B lights me up …….. More later!
The 2B is extremely well made and has a good solid feel, the rotary knobs and controls feel good and made to last, It’s so easy to use that Madam got her head around the control in 5 minutes.
My Mistress loves the fact that she can get a digital read out for the power level she is giving me, She loves making me take higher power settings and gets real joy from watching me beg for mercy which normally results in yet another higher power setting !
The real beauty of the 2B is that you can use an external power supply which really does add loads more punch to the power levels, It also means that you get no battery drain as if you use the device for longer periods of time the power levels remain painful / pleasantly the same.
The most power I have done is 50% of max power and let’s say I was jumping for joy !, I dread (Can’t wait) for the day she makes me take 90 – 100% power, that’s her evil side,
She knows having me bound and helpless to stop her upping the power is magical and a real turn on ! Another good thing with EStim is you can up the power and have you partner buzzing and if needed you can instantly turn off the power, that’s good to know!
With the 2B you can set the power setting’s low and get a sensation like pins and needles, play with the settings a little more and you get a wonderful relaxing feeling as if fingers are being run over you scrotum, Very erotic, Great for solo play as you can tease yourself for hours, Not sure if you meant to use EStim for 2 or 3 hours, But it feels too good to stop !
Then when you warmed up you can go for the stronger power settings that feel make you feel like you have been struck by a thunder bolt, One good thing about the 2B is that if you change mode setting it always goes to zero power setting, thus avoiding any sudden unwanted surprises,
For folks with multiple piercings
I have discovered that I need to protect my Prince Albert piercing from higher power setting, a condom or tape over the PA ring protects it ! The PA is OK at lower power settings, But higher level zap like hell ! As the PA is more sensitive than other areas down there if the PA makes accidently contact with my other piercings which are live I get a chain / zap effect I get a reminded that my PA has made contact with my other piercings that are live via the rubber conductive ring that I use.

All in all I totally sold on EStim, I will be back to get a motion / remote device, that sounds like something to test out while shopping.

Well done to you guys at EStim, You have brightened up my sex life loads, Happy New to you all

As before very good sevice and communication, the new power pack is excellent
and very well thought out has great controls,

I was lucky enough to experience a good few hours of the 2B in Audio Mode using its internal microphone to listen to music in a very busy shop. I was wired with a set of pads on my ass cheeks and a set of pads on my inner thighs. They were wired left and right into the 2B. I can honestly say it was a new experience for me. I have used the 2B a lot in other modes but the Audio Mode was constantly changing which kept things interesting. As the beat and volume of the music changed, so did the feeling of the electro both in terms of feeling and intensity. I would recommend that anyone with a 2B gives the Audio Mode a try as it is a new and exciting and could be a great way to torment someone without the need for input for a while!

Surprisingly sturdy, yet small and lightweight for the power it delivers. Get it along with the power supply or you won't be able to feel it's full potential. Most of the built-in functions leave me cold, but there is enough variation. Read the manual for a description of the modes included.
The physical interface is a mixed bag. The knobs have good grip and a consistent turn rate. I'm not thrilled about the Select button and the difference in function for that button based on the amount of time you depress it. Quite irritating to inadvertently cut to the mode selector when you want to adjust the feel of the mode. This can probably be fixed in software though. The external power cord gets in the way of both the knobs and the power switch. On my unit I was appalled by the build quality of the power switch. Almost any sideways tap to the unit would make it shut down, ruining the experience. This was dismissed as normal by the support team, otherwise I would not have mentioned it.
It's a shame that the audio and digital link share the same jack, which necessitates an (expensive) custom USB cable.
[Ed: The USB Cable contains the Interface electronics - It is NOT a standard USB cable]
Interfacing the 2B with a computer is a breeze when you have the connection cable. The API is open, which puts this unit ahead of the competition on that subject. Several user-written control apps for various devices have already been developed.


This is a very nice power box. I really like the small increments that you can increase the power. It's everything I expected. In high power mode, it's got enough to make me scream, even without the optional mains power adapter. No major complaints at all. Only minor issues I have is that the "A" power adjustment knob appears to have been pushed onto the box a little too hard, so it rubs on the face of the box, but it works just fine. Also, when the batteries get low, it seems like the "A" and "B" power levels appear to be linked. At higher levels, if you decrease one, the other one increases. Not sure why? All in all, it does the trick... Oh, and my wife liked her first experience with E-Stim, too, thanks to the 2B ]:)

I Love my2B wave and waterfall arête two favourite modes especially when used with my tri-phase cable

God it is powerful!!!. even on low power I can HFO every time. Bought the 1.03 version, and the upgrade software worked the first time.

My 2B has just arrived, and all I can say is what a fantastic bit of kit. The packaging was great, delivery was quick, and it even camel with some sticky electrodes. I used to have a EM32, and this is far far better. I love the bounce mode it gets be going every time.

Gret kit Great Service 5/5

Had the 2B for nearly a week now. Have been using flange and conductive rubber ring. Can sit and play with the settings for hours exploring the most pleasant sensations! The ring made quite spiky, sometimes sore feelings at first, but I think I've got used to it, and it's nearly all perfect! I can't imagine why it has a 'high' power setting!! I've used a box by another company and even on full it is barely able to keep up with the 2B on 20-30%! The modes are sensible, they don't change all the time like some other boxes- you change everything to suit. I just wish the wave/waterfall modes could be more customisable in terms of the repeat frequency. Audio is the way forward! First ever HFO today in no time at all with track 6 of the included cd using the flange anally/cock ring combo. Turning up the audio response setting from 50-60-70- WOW! What a product. It felt like being fucked and masturbated at the same time but like the stimulating hand is inside you as well as on the outside.. Well can't do it justice with description really. And to think a week ago I'd never heard of electrostim. Completely different to anything I've ever experienced. Thanks to you guys!

I've had my 2B for just over a week now and OMG. This is one fantastic piece of kit. I owned a basic model 2 a while ago but this is awesome. HFO is the norm rather than the exception. The 2B is particularly good with the mains adapter as the model I had before drained the twin batteries within a short space of time leaving me feeling disappointed. I used the audio CD for the first time today and was blown away. Thanks E-Stim Systems.
