Product Description

The ET312B you've come to love – now in a stealth black enclosure. HOT!

Whether you've been into electrostim for awhile or are just getting started, there is something to be said about having the best and safest equipment. Until now, there was no single device that offered the power, safety, and ease-of use of the ET312B. American designed and crafted. Not a repackaged TENS unit or signal generator. This instrument is the result of over 3,000 hours of focused design effort, with one single end in mind…

E-Stim Excellence!

There are power units that sell for less, but none of them offer 18 pre-programmed modes -- each designed by an experienced e-stim master to provide a variety of sensations all under computer contol without continuous knob twiddling. Each routine can be quickly selected on the bright, backlit display using 2 pushbuttons. Once selected, the tempo and frequency are easily adjusted using a single "MultiAdjust" knob, not two or more on other power units. And the intensity level is easily adjusted using separate knobs for channels "A" and "B" with the current levels clearly displayed at all times.

Powerful yet Precise

The ET312B is powerful yet precise. Feature-rich and intuitively easy to use. There is no other power unit like the ET312 anywhere. Mention the ET312 to anyone into e-stim. They'll know what you're talking about.

I use both the ET312B and ET232 units a few times a week and have had some amazing sessions over the years. If the price or features seem too much, I suggest the ET232 which has many of the features found in the ET312B in a smaller and more affordable package.

Unique Features:

  • Designed and Made in the USA!
  • Built-in rechargeable high-capacity battery for up to 24 hours of non-stop stimulation... you'll probably need sleep before it does!
  • 18 built-in routines including waves, intense, random, and 3 audio modes.
  • Up to 6 user-selectable routines can be added using the optional ErosLink software.
  • Full Stereo Audio modes allow audio based stimulation from mono and stereo sources (including SmartStim and Phaser waveforms). Included microphone turns ambient sounds, music, or your voice into stimulation. Also works with your computer, iPod, CD player or any other stereo playback device using included stereo cable.
  • Measures 8.0" x 6.5" x 2.5" and weighs 4 pounds
  • Easy-to-read Backlit LCD displays current mode and output settings for channels A and B even in the dark.
  • Multiple Power Settings: 3 power ranges allow a finer adjustment of output level, from mild to wild!
  • Microprocessor-based sessions allow hands-free stimulation. The end of monotony!
  • Unique Tri-Phase output creates a third stimulus waveform between channels A and B for even more variety and creative electrode placements... see our TriPhase Adapter for more information.
  • 2 sets of 52" long leadwires with factory molded 4mm banana plugs 
  • Bananas to Pins Adapters available for TENS / 2mm accessories
  • 1-Year ErosTek Warranty
  • 100 - 240VAC autoswitching AC adapter includes plugs for USA/Canada, EU and UK. Lightweight and ideal for travel. Can be used in other countries with a simple mains plug adapter.

  1. As always a great product

    Posted by halon1301 on 6th Jun 2015

    I've had the ET232 for a few years now, I love that little box, but I decided I wanted some more settings to play with when I have a sub tied down and 'begging' for more. I've only had the box a week, but it's everything I expected and more. As always, great stuff from ErosTek, they make awesome electro gear, and I keep coming back for more!

  2. H.F. Orgasms 99% of the time

    Posted by Voltair on 30th Jan 2015

    I can't remember when I bought my first one but it was a long time ago. I have gone through 2 and I am working on wearing my third out. Face it, they can only take 6 hours of use per day for so long. I am NOT complaining, it's a very good thing that they last far longer than expected.
    I love the Tri-phase programs and have downloaded a few programs from the CD. I have a wide variety of programs to use while I am writing or editing photos.
    I will be ordering my 4th soon but again, I wear them out, the machine doesn't wear out on it's on, I kill them, oh yeah, I never use anything but the high power level and I change the settings almost continually!
    To be fair, most all of the electronics I have seem to have a short lifespan.

  3. Orgasmic Bliss

    Posted by Paul on 23rd Oct 2014

    I have owned one now for just over two years, and like others here I want to describe the orgasms one has yet they are completely different than hand, oral, anal or vaginal sex. Each session with the ET-312 is different, like have sex with a different partner every time. I have it hooked to my computer 24/7 and when I stim always 2 channel, I have complete control over my pleasure.
    Rating sex toys is not easy and yes the Et-312 is pricey but considering the pleasure I have gotten from it, it paid for itself many times over, it never complains has a headache a bad day at work or do I need to think whether it has an STD.
    I honestly think that the construction of the box is well designed easy to use and a joy to experience. I hesitated like most do when purchasing it, but I have never regretted it.
    The box is not addictive just the sensations, the crack cocaine of masturbation, you deserve to feel what it delivers.

  4. The Best, Most Exciting Electro Unit Out There!

    Posted by DragonMSTR on 13th Mar 2014

    The boy bought the unit for me 5 years ago (I always love getting gifts that are really meant for him).

    After a sit down with the manual, I took it for a solo test drive. Incredible! The fact that the two channels are independent of each other makes this the "Mercedes" of Electro power units. And with so many modes to choose from, the excitement is none stop.

    I like that I can select and set the power level I want from low to high, depending on how intense I want things to get. Once set, I then select one of the modes and we're off and flying.

    I knew it was exceptional when my sub wasn't able to string two coherent words together while hooked up. And that has happened on many occasions! I love sitting back adjusting the controls and watching someone cum with electrode stimulation only.

    The unit has lasted extremely well, but the battery has given up the ghost. Not a major issue, because I use the adapter most of the time.


  5. Super

    ET312B is super machine.I love program intense.Thanks from Slovakia :)

  6. Delightfully Devious! This is no TENS machine!

    Posted by Frodo on 28th Jan 2013

    I am so surprised at how terrific the 312B is. It is addictive. It is hard to spend less than an hour using it. TENS machines are dull and boring after a few minutes. The 312's programs are all very, very good. Waves is exactly what it sounds like, but it isn't the same wave repeated over and over. You cannot tell when the program begins to repeat because it is not repetitious. None of the programs are.
    The tri-phase is also very good - and not just with the 3 tri-phase programs. There are programs that pulse up and down, or make you feel like your cock is being twisted, hammered, in a vortex. There is just no way to explain the uniqueness of this product.
    A couple of programs may feel just so so - that is until you turn the multi-adjust dial.
    It is so good it should be illegal! And, no, I not being paid to write this, but if sales increase, please send a gift! Great Job!!!

  7. I love it!

    Posted by Ivan on 23rd Sep 2012

    I needed a week to say: Woooow this is the best toy of all time. Lots of options, lots of different sensations, a lot of enjoyment and incredible orgasms. Yes, that's my EROSTEK ET-312B.
    I love it!

  8. Best SexToy ever

    Posted by Unknown on 1st Sep 2012

    I've bought it for 2 years and it's the best toy I've ever bought. Easy to use, creates very difficult feelings and it gets you off in more than 3 hours or in less then ten minutes ... as you like it. I just have to say: Give it a try! You will never be disappointed.

  9. The best when nobody is here to explode in!

    Posted by Donnie on 25th Jul 2012

    I have the prostate stim in now! I love it! Every time I start playing with it, I play for six hours. It's so much fun! I love the fact that it has two channels so my friend can feel as good as me! pre-... is flowing

  10. My Best Friend

    Posted by Mark on 9th Jul 2012

    I bought my 312B almost seven years ago and it still brings me the most enjoyable moments. When I first saw someone hooked-up and cumming, truly hands-free, I thought it was trick photograpy. I went to the top, buying a 312B, and at first, had some difficulty understanding just how to use it. It did not take too long though to master the machine. The real key is plenty of lubrication. I can play with myself for literally hours, taunting myself to orgasm, and backing off until I can't take anymore and just have to finish. My orgasms are so intense using this machine that it rocks me to the core. Nothing comes close to the feeling I get when riding this device. If there were ten stars available, I would give it a ten!
