Description
The ElectraStim Linx (model EM220) is ElectraStim’s first fully app-controlled dual-channel electro stimulator. It runs as a stand-alone controller straight out of the box, holding 23 preloaded patterns you can use without a phone anywhere near it. Bluetooth pairing with the free Linx app (iOS/Android) unlocks the rest of the unit: motion-triggered Tilt and Flick modes, audio-reactive Microphone mode, Stereo Stim, and a custom Playlist builder for sessions that loop and layer on their own.
The headline feature is Remote Control mode. Generate a one-time access code and a partner anywhere in the world can take live control of both channels — patterns, intensity, timing — from their own copy of the app. No cables cross the distance, no dongles, no shared accounts. It works the same whether that partner is in the next room or another country.
Electro stimulation carries real, general safety rules that apply to any e-stim device, including the Linx. Anyone with a pacemaker or another implanted electronic cardiac device should avoid it unless a clinician has signed off and pads stay well clear of the device. Pregnancy, epilepsy, and an unstable heart condition are also reasons to sit this one out. Pads should never go above the waist or anywhere near the heart. Skip any patch of broken or irritated skin, and begin each session on the lowest intensity setting before building up from there.
Things to know:
- Dual-channel stimulator with a symmetrical bi-phasic waveform — the signal drives in both positive and negative directions rather than one-way, for a fuller sensation than the asymmetrical output used on many rival units
- The two channels run 180° out of phase (interpolated) so each stays isolated, giving stable rather than fluctuating intensity per channel
- 99 intensity levels per channel, adjustable independently from the unit itself or the app
- 23 built-in patterns (11 Wave, 12 Pulse) usable stand-alone with no app required
- 9 play modes in total once connected to the free Linx app via Bluetooth: Flick, Tilt, Stereo Stim, Microphone, Playlist and more
- Custom Playlist builder — combine adjustable “snippets” (rise, hold, fall and rest timing, pulse width, frequency) into a session up to an hour long, with a different pattern running on each channel
- OLED display with tactile button controls and on-screen battery indicator
- USB-C rechargeable battery: up to 6 hours of play per charge, around 3 hours to fully charge
- Power output compatible with up to 4 uni-polar accessories, 2 bi-polar accessories, or 1 quadripolar accessory
- Dimensions 118 x 68 x 25mm; weight 116g
- User-updatable firmware, so new patterns and features can be added after purchase via ElectraStim’s update software
- Compatible with the full range of ElectraStim electrodes and accessories
- Not for use with a pacemaker or other implanted electronic cardiac device, during pregnancy, or by anyone with epilepsy or an unstable heart condition; keep pads below the waist and away from the heart, never apply to broken or irritated skin, and start at the lowest intensity

Frequently Asked Questions
Is the ElectraStim Linx safe to use with a pacemaker?
The ElectraStim Linx is not suitable for anyone with a pacemaker or other implanted electronic cardiac device unless a clinician has confirmed it’s safe and pads are kept well clear of the device. The same applies during pregnancy and for anyone with epilepsy or an unstable heart condition — these are general electro-stimulation contraindications, not specific to this unit.
Do I need the app to use the ElectraStim Linx?
The ElectraStim Linx works as a stand-alone controller straight out of the box, with 23 built-in patterns accessible from its own OLED display and tactile buttons — no phone required. Pairing it over Bluetooth with the free Linx app (iOS/Android) adds nine play modes in total, including Tilt, Flick, Microphone, Stereo Stim and the Playlist builder.
Can someone else control the ElectraStim Linx remotely?
The ElectraStim Linx has a built-in Remote Control mode: generate a one-time access code and a partner running their own copy of the Linx app can take live control of both channels’ patterns and intensity from anywhere with an internet connection, with no extra cables, dongles or shared accounts needed.
