First steps:
Turn on your LINX by pressing the power button. The OLED display will confirm that it is ready for use. LINX starts at zero intensity, allowing you to select your desired mode before increasing the intensity.
Using electro-accessories: Connect your desired accessory to one of the stimulator's two channels. The intensity of each channel can be adjusted independently. To complete the circuit, connect either two unipolar or one bipolar electrode to each channel.
Selecting play modes: On the LINX e-stim device itself, you can choose between wave patterns and pulse patterns, each offering a variety of preset rhythms and sensations. To access all play modes, including Flick, Tilt, Stereo Stim, and playlists, connect your LINX to the free app on your mobile device.
Changing intensity levels: Use the arrow buttons on the stimulator or in the mobile app to adjust the intensity in 99 steps per channel. You can gradually increase or decrease the intensity, or hold the button down to quickly increase or decrease the levels. Both channels can be controlled independently for personalized sensations. Use the Boost function in the mobile app to temporarily increase the intensity of each channel.
Connecting to your smartphone: Pair LINX via Bluetooth with the free Electrastim LINX app to unlock additional play modes and control options. On the stimulator, select "Connect Smartphone," open the app, and tap "Find My LINX." Your device will appear in the list. Simply enter your stimulator's serial number to establish the connection. Once paired, you can browse all play modes, customize patterns, and adjust the intensity directly from your smartphone.
Remote control connection: With the innovative remote control mode, your partner can take control from anywhere in the world. Share your unique control code with them, and they can control patterns and intensity in real time. Ideal for erotic play over long distances. No additional cables or accessories are required for the remote control.
Charging your LINX e-stim device: Charge LINX using the included USB-C cable. A full charge takes approximately three hours and provides up to six hours of use. However, this may be reduced at higher intensity levels. The battery indicator on the OLED display will signal when charging is necessary.
Specifications:
- Patterns: 23 pre-programmed patterns (11 wave patterns, 12 pulse patterns).
- Intensity levels: 99 levels per channel, adjustable via the stimulator or the mobile app.
- Power: Dual-channel stimulator, compatible with up to 4 unipolar, 2 bipolar, or 1 quadripolar accessories.
- Battery: USB rechargeable battery, up to 6 hours of use per charge, charging time 3 hours.
- Firmware updates: Keep your LINX future-proof with firmware updates. These updates add new patterns, improve features, and fix bugs.
- User interface: OLED display with tactile buttons and clear menu navigation.
- Dimensions: 25 mm x 68 mm x 118 mm, Weight: 116 g.
- Ideal use: Solo use, partner use, or remote-controlled applications. Suitable for advanced users who desire intense stimulation.
Unlike most electrostimulation devices with an asymmetrical output waveform, LINX generates a symmetrical, biphasic waveform with a net DC current of zero. This results in a more intense stimulation sensation because the signal is driven in both positive and negative directions, instead of just one as is typical.
The red curve below shows the output waveform of Channel 1, and the yellow curve shows that of Channel 2. Both channels have a 560-ohm load and are operating at maximum intensity.
Each line in the graph represents an amplitude of 50 V at a time base of 2.5 ms.

It is also important to note that the two channels are 180 degrees out of phase, i.e., interpolated. This is crucial to ensure the isolation of the two outputs. Dual-channel stimulators that are not isolated in this way will exhibit fluctuating and unpredictable intensity values.
Firmware Updates:
The Electrastim LINX features user-upgradeable firmware, ensuring you always benefit from the latest features and enhancements. Updates can be installed directly through the Electrastim LINX app or using the Electrastim Update Software on your desktop. This gives you immediate access to new patterns, feature enhancements, and important bug fixes upon release.
You can download the Update Software now to be notified when a new update is available.
The Electrastim LINX requires Update Software version 4.1 or later.
IMPORTANT: Before performing a firmware update on your Electrastim LINX EM220, please ensure that:
1. Your LINX firmware version is older than the latest version.
2. You want to use all the features listed, as updates cannot be reversed.
Note: If you have updated your LINX app on your smartphone, you may also need to update your firmware to restore compatibility.
How do I find my LINX firmware version?
Turn on LINX and select "Settings/Technical Information" from the menu. Here you will find your firmware version and other useful information.
Current version as of January 12, 2026: Version 1.0.
Smartphone compatibility:
To get the most out of LINX, your device should support Bluetooth Low Energy (BLE) 5.0 or higher. This ensures a reliable connection, improved responsiveness, and the best overall performance for features such as long-range mode or high-speed data transfer.
If you are unsure which Bluetooth version your device uses, you can find this information in your device settings (usually under "About phone") or by searching online for your model name.
