    ElectraStim Flux Electro Stimulator Additional Information

    Flux harnesses powerful outputs and award-winning technology to provide you with a simple to use but endlessly versatile stimulator for the e-stim purist.

    Utilising our handheld stimulator design, Flux is packed with innovative features that give you the tools to experiment with a vast array of scenarios. Imagine a bondage scene with your sub; they’re tied and laid prone with accessories in place, ready to bend to your every whim.

    A dismissive Flick of your wrist while holding Flux sends a sharp spike of intense stimulation their way; the sub’s body reacting with surprise at the sudden overwhelming pleasure. Or balance Flux upon their body in Tilt mode; the slightest movement will cause the stimulation to increase or decrease. The question is, do they want to stay still or continue to wriggle?

    Flux also contains more than 20 pre-programmed Wave/Pulse patterns and utilises advanced audio-processing controls (Stereo Line-In and Microphone modes) so your favourite music, stereo-stim tracks or any other ambient noise (screams of pleasure?) can be used to control the stimulation in unique ways. The bright, clear OLED display not only matches the monochrome aesthetic but also gives you live readouts of your play mode, intensity levels and battery gauge.

    With 99 intensity levels, Flux sits with the most powerful stimulators on the market and builds upon the decade long success of our own SensaVox unit to improve performance and usability for BDSM markets. Twin outputs allow for a huge variety of accessory configurations, while the high capacity rechargeable battery ensures lengthy play-time is a breeze (Flux also charges from flat to 80% in under an hour).


    • Dual output
    • 99 Intensity levels
    • 6 Play Modes. 40+ options.
    • OLED graphic display
    • Motion control modes (Flick & Tilt)
    • Sound control modes (Microphone & Line-In)
    • Rechargeable lithium-ion battery (0-80% charge in under an hour)
    • Adhesive electro-pads included



    Wave/Pulse Modes - Pre-programmed patterns that showcase a range of sensations (11 Wave/12 Pulse)

    Flick Mode - Inherited from our EM60 unit, our patented Flick mode utilises the internal accelerometer. Literally flick the unit (like cracking a whip!) for a virtual spank of intensity to the connected accessory. 5 Varieties

    Tilt - Tilt Flux to control the sensation with precision. 5 Varieties.

    Microphone - Flux responds relation to external sounds/voice using an integrated microphone. 5 Varieties

    Line-In - Use direct line-in audio (from any audio source with a 3.5mm headphone jack) to control the stimulation. 4 varieties.

    Note: Battery Health

    Flux has an internal battery management chip that provides an accurate reading of the health of your battery as well as how much power is left. Please note that during the first few charge and recharge cycles of your new device, the chip is still learning about the battery and may seem to show unusual changes in percentage.

    This will cease when the battery has been fully discharged and recharged a few times and is a normal process. Your battery readout (and health percentage) will stabilise at its optimum performance level after this point. For more information, please contact us on info@electrastim.com

    One of the Best Purchases I've Ever Made

    I bought one of these a year or so ago and it still works great to this day. My spouse and I love it.

    ElectraStim Flux Electro Stimulator - EM180

    Really big improvement on the EM80 I bought some 6 years ago ( which is still working just fine) For me the range of settings and greater power just set the flux above by a fair bit. It comes in a nice case with enough to get started but I would advise trying all the toys as they enhance play considerably.

    Would like to give it a 4.5

    The unit seems to be well built and so far the battery life has been very sufficient. Shipping was very fast. Controls are easy to use but I would have preferred dial controls for the intensity. Toggling to the different functions can be a bit awkward but I’m getting used to it. I’m pretty happy with how it operates and feel like I’ll get better at finding the functions that work for me.
    My first impression using it was mixed. Ultimately, it’s a fancy TENS unit with different patterns programmed in. Some of it seems a bit redundant but it does what it does really well. I have found it to be just a little underpowered in certain configurations, but so was my TENS. I do like the tilt function. It’s easier than fiddling with the controls on my TENS. The flick feature is going to take some getting used to. I don’t see me using it much.
    Now for what I really like about this thing. Using the two channel audio input allows me to use my favorite stereo stim files for some intense sensations. It works super in a tri-phase configuration and the output levels can be wonderfully extreme. I had built my own stereo stim box and was never really happy with it. When I cooked the outputs I went back to my TENS and started saving for a commercial unit. After a lot of research I settled on the Flux and am really glad I did. I’ve had some intense edging session and some mind blowing hands free orgasms. I likely won’t be using any of the other modes. At least not often. They’ll be handy for showing newbies the basic feel of what it’s like before sending them into orbit with an audio file.
    All-in-all, I really like it! THANKS!

    First device, enjoying it!

    After a mishap from ordering and needing a replacement immediately, which support did respond ASAP for their time zone, I got my new device and tried out Estim for the first time ever. First couple uses weren't painful per say, but didn't feel good. Then I found an electrode setup that worked for me and it was great.

    The device seems well made, and has plenty of power, though I did recently max it out briefly during a tipping point. Menus are very easy to navigate once you understand the buttons to do so. My only gripe would be clicking sound for buttons, which is unnecessary design wise when you have a beeping function toggle if you want something like that. One of the big pluses for Estim is not making noise during use and it somewhat dampens that plus.

    Tips: Devices come fully updated, so don't try using their updater from this site, right away and potentially cause an issue like what happened with me.

    Also grab some of the loops, they are way better than the pads if you ask me. Make sure they are compatible with your cords pins.
