The ErosTek ET312B was developed in 1999 and has been in continuous production for over 20 years. 

Production relied on components which became harder to source or went obsolete. The technical aspects of manufacturing reached a breaking point during the COVID-19 pandemic. We continued to sell new units using our existing component inventory but soon realized that the final chapter of the ET312B was ready to be written.

ErosTek ET312B


Do you already own an ErosTek ET312B? If so, you may consider yourself lucky. These units are considered my many to be the very best in erotic e-stim power units and most continue to operate even after 10 – 15 years with regular maintenance and repair. We sell Repair Parts for the ET312B so that you can keep your unit running for years and years. And the 1-Year Warranty remains in effect for any units purchased from us in within the last year.


We’ve learned a lot in the last 20 years and seen the changes in technology related to networked devices (IoT), embedded programming and PCB manufacturing technology. We aim to create the very best unit, one that incorporates features we often use but haven’t seen on other devices. We have a lot more options available now that we did 20 years ago. And we also have be nimble and able to move with the current supply chain disruptions, microchip and component shortages to keep the design simple and effective. In short: We are working on it. Stay Tuned.


If you’re in the market for a new e-stim power unit, we offer 3 solid options:
1. ET232 Power Unit and ET232 Package Deal
2. 2B Premium Pack
3. ET302R Remote Power Unit

Each of these offer a set of features designed for those starting out or wanting to get more from their e-stim sessions. 

Thanks again for your support.

    Eric, it’s a bitter sweet moment for me but I’m hoping the next generation Erostek unit will be a success. Thanks for providing me with many many hours of estim pleasure. I currently own 4 ET312B ‘s and alot of your toys/gear. Take care and stay safe.

    Eric sad to see the run end. Love my Et312 and my little 232 as well.

    I feel confident you will create something terrific as your next new power box and hope to be included in any testers you might desire.

    This is sad news. I started my buzzfuck journey with the 232 and graduated to the 312 a year later. Been ole faithful ever since.

    The only other box I use is the coyote because it’s newer and “digital” and compact and has some customizations I WISH the 312 had, but the quality of the box leaves much to be desired.

    I’m looking forward to seeing what your newest creation is, and what it can do.

    Greetings from nyc
