Frequently Asked Questions

Q: How much power does it have?

 A: The ErosTek ET232 has more power than a TENS unit and slightly lower maximum output than our ET312B. Its routines are designed for erotic e-stim which makes it far better than a common TENS unit, and it's easy access to modes, levels, and speed (MA) makes it super-easy to operate, even for beginners.


Q: How does the 232 differ from your other products?

 A: The ET232 works great as a solo e-stim device where easy access to modes and levels is preferred and complements the ET312 with its smaller size and newly designed factory routines. Many die-hard ET312 users also have an ET232 for added variety. Its small size makes it easy to take e-stim anywhere. The ET232 makes a great introduction to e-stim. It's easy to use and can be taken anywhere with its 9-volt battery and included universal 100-240 VAC adapter. The ET312 adds features such as TriPhase, advanced stereo audio and wavefile processing, LCD display, user-defined slow ramp, longer-life rechargeable battery, and higher power output. These features come at a higher cost, in a larger and heavier case, with an additional learning curve required to get the most out of it.


Q: Can I use stereo .wav files with the ET232?

 A: The ET232 accepts audio through its Audio input. You'll need a Stereo Audio Cable to connect external audio devices to your ET232. Keep in mind that the ET232 downmixes stereo tracks to mono, so you'll have wide-range of AudioStim effects, but for full stereo stim, our ET312 is the best way to go.

  1. Superb little pleasurebox!

    Posted by Anders on 6th Jan 2015

    Have tried lots of different stuff, tens, ems, and connect the above with high output Power supplies, worked quite som time, but now they are broken, couldnt handle big power output of course. Desided to invest in real thing and have not regret it!
    Give much more Power and Variation compared to tens or ems!
    Only thing I miss is the possibility to get stim from 2 different program, wich i did get when I connect me to 2 different ems Machines, and I can tell it was a thrill!
    So if you buy 312 you can get it - question is if it Worth the extra Money...only downside with estimming is to do it to often, the effect then is not so intense then, and you can get numb of driven up the Power to much. So the advice is to only enjoy this machine ones a week - the you really get rewarded - that feeling is outstanding!!

  2. Awesome little power box!

    Posted by DragonMSTR on 31st May 2014

    When this arrived I had to try it out right away. I've had the E312B for a couple of years now, but wanted a smaller unit for those times when the larger power box was not practical. I also wanted a power box that did more than simply pulse on and off.

    The E232 is incredible!! So many settings to choose from in one little box. Even the audio settings were great...(audio soft can almost pick up a heartbeat!) And depending on the setting you choose, the M/A does more than adjust the frequency like other brands.

    If there's any disappointment (if) it may be that the "User" defined setting isn't functional as such. But set to User, it still operates the same as the HiFreq setting.

    No, I was not let down by this in anyway. I know that ErosTek makes quality EStim power units, and the E232 is no exception. It is a great power box with multiple settings, and is an incredible value for the price.

  3. Simply Superb

    Posted by Steve on 8th Dec 2013

    With two channels each with its own independent gain control and a control to alter how the channels behave with respect to one another, this little EStim unit represents excellent value for money.

    Yes you can find cheaper units on any erotic supply website, but the people who know about EStim are recommending Erostek units and you definitely get what you pay for. Here you are paying for quality. Just having it in the hand is enough to show the quality.

    This unit has something like 15 different patterns of stim, and the channel alternation can be tweaked almost infinitely.

    The only features this unit does *not* offer are independent pattern setting for each channel and no external computer control. I've missed both at times what the unit *does* deliver overshadows the lack and provides the potential for hours of fun.

    The unit can be powered from a wall-wart power supply or by an internal 9 volt battery.

    The only downside is the disconcerting numbness that happens after I've pushed things a bit hard. Gotta love that "throb" pattern.

  4. Technical Pleasure in Small Package

    Posted by Unknown on 1st Jun 2012

    I have had my ET232 now for just about a month and I just can't leave it alone. I had been estimming via stereo hookups but the bulk of the equipment left me stranded in my man cave which is not very comfortable. Also, I have a rimba unit which was so-so, I got off a couple of times with it but it bored me due to its lack of versatility. So as soon as the budget allowed, I went for the 232. I make my own "trodes" and where the rimba leads are smaller I fixed that with radio shack male adapters. I have the Pulsinator suite and use an insignia radio/cd player to provide the stim audio and it gives me incredible pleasure with edging being right up there. I can pick the milker audio and have it replay via the 232 and what a wonderful rush when the triggers are squeezed. I am a heterosexual dude, who has had to masturbate for lack of sex with spouse who has clinical issues. I prefer not to have an affair. She is fully supportive of my using the 232. So, for this old cock (69) I say there are 15 good reasons for buying and using the 232. I'd give it 5 stars if I could get a stereo feed off the unit. Nevertheless the audio system works fine, i.e,it gets the job done.

    Try it, and you will get addicted to it.

    Here's to estimming withs equipment that gets the pleasure done. Cheers all
