ElectraStim Flux electrostimulation control unit

Flux represents the logical evolution of the Electrastim range. I rank this model among the most complete units on the electronic BDSM market: it combines raw power (99 levels) with truly innovative control technology. Frankly, it is the benchmark unit for anyone who wants to explore electrostimulation without compromise.

Technology and control modes

Flux offers six distinct modes that cover virtually every imaginable scenario. The two audio modes (Microphone and Line-In with stereo processing) let you synchronize stimulation with external sounds—voices, music, or ambient noise. This is particularly interesting in a BDSM scene where the dominant partner can orchestrate the intensity in real time.

Flick and Tilt are what make Flux truly unique. Thanks to an internal accelerometer, you control stimulation with wrist movements: a sharp gesture (Flick) simulates an electric spanking, while tilting (Tilt) enables smooth, precise control. I’ve seen plenty of feedback come through the shop: this motion technology genuinely changes the dynamics of play.

Beyond the modes, you have access to more than 20 preprogrammed wave and pulse patterns, plus the Zero Override option, which maintains a constant intensity when changing modes—a feature requested by the most experienced users.

OLED display and user interface

The bright OLED display, visible from every angle, shows the intensity, active mode, battery level, and technical information in real time. This is far from cosmetic: in the middle of a scene, being able to read the settings without searching for them genuinely improves the experience. The monochrome aesthetic appeals to users who appreciate a discreet, functional look.

Battery and usage compatibility

Flux features a rechargeable lithium-ion battery charged via USB. Charging from 0 to 80% takes less than an hour, which is reasonable for a unit this powerful. Two adhesive electrode pads are included in the box, allowing you to get started immediately.

In terms of compatibility, Flux uses dual output, meaning you can connect two electrostimulation accessories simultaneously (two pairs of electrodes, two plugs, etc.). This versatility is a major advantage for couples or for exploring different areas.

• 99 fine intensity levels (precise sensation control)
• Dual output (two compatible accessories simultaneously)
• 6 distinct modes + 20+ preprogrammed patterns
• Flick & Tilt modes via accelerometer (unique gesture control)
• Stereo audio modes (Microphone and Line-In)
• High-visibility OLED display
• Zero Override option (constant intensity between modes)
• USB rechargeable battery (charge < 1h)

Who it is really suited for

Ideal for: intermediate to advanced users who already understand electrostimulation and are looking for a technically rich unit with innovative modes. BDSM couples who want to synchronize stimulation with audio or explore motion control. Dominant partners who appreciate highly precise control and a visible interface.

Less suitable if: you are a complete beginner to electrostimulation—the learning curve is real, and the 99 levels can be intimidating at first. I recommend consulting our complete guide to BDSM domination to fully understand the context before investing in such a powerful unit. If you are looking for something simpler to get started, choose an entry-level unit instead.

A word of advice from a friend— Flux is a serious unit that requires respect and a good understanding of electrostimulation safety principles. Read the documentation, test it on yourself at a low level first, and communicate clearly with your partner about the sensations. It is an investment, but it is truly worthwhile if you are committed to the practice.
