ElectraStim LINX EM220 is a premium dual-output electro stimulator built for three distinct ways to play: directly from its tactile controls, locally through the ElectraStim LINX app, or over the internet with a trusted remote partner. Each channel has its own 0-99 intensity control, so a solo user or couple can balance two compatible accessories rather than treating both outputs as one setting.
This is specialist electro-play equipment, not a medical device. Read the complete manufacturer instructions before use, keep every output at zero while connecting or removing accessories, and use only compatible ElectraStim electrodes and cables. LINX is for below-the-waist use only and must not be used near water, on damaged skin, or by anyone covered by the contraindications below.
What makes LINX different
LINX can operate without a phone. Its stand-alone menu contains 11 wave patterns and 12 pulse patterns, while the onboard buttons provide direct control of both output channels. When paired with the LINX app, additional control styles include continuous, wave, pulse, tilt, flick, microphone, stereo-stim and custom playlist functions. The app also supports internet-based remote sessions using a temporary nine-digit code.
The device uses a symmetrical bi-phasic waveform with zero net DC. In practical shopping terms, the important distinction is control: the two outputs are isolated and independently adjustable. ElectraStim lists 100 intensity levels per channel, numbered 0 through 99, plus user-set maximum intensity limits. Those limits are especially useful before giving a partner remote access.

What is included
- ElectraStim LINX EM220 stimulator
- Zipped protective storage case
- Detachable belt clip
- USB-C charging and data cable
- Two output cables
- Four self-adhesive ElectraPads, model EM2118
- Reset pin
- Quick-start guide and warranty-upgrade information
The included pads provide a complete starter setup: two pads are required to complete one circuit. The second channel can remain unused or connect the other cable and two pads. For other configurations, browse compatible electro pads and loops and electro accessories. Always follow the instructions supplied with the exact accessory; a connector that fits is not by itself proof that every placement or combination is appropriate.
Stand-alone, app and remote control
Stand-alone
Use LINX without a phone when you want direct, tactile operation. Choose from the 23 built-in wave and pulse patterns, then adjust each channel from zero. The power button can be pressed momentarily to return both outputs to zero. A keypad lock helps prevent accidental adjustment once settings are established.
Local app control
The LINX app connects through Bluetooth Low Energy. ElectraStim says BLE 5.2 hardware performs best, while some BLE 5.0 phones may work with reduced responsiveness. App modes can use phone movement, sound or custom playlists, but capability depends on the phone, operating system, current app and firmware. Some live-control modes pause when the app goes into the background or another app takes over the microphone, so do not assume phone control will continue without pauses or network delay. Read our app-controlled product guide for broader connection and privacy considerations.
Internet remote control
A wearer connects LINX to the app, generates a temporary nine-digit session code and shares that code with the chosen controller. The remote partner can then control the active session over the internet. Responsiveness depends on both internet connections, the local phone and its Bluetooth performance; changes may lag or occasionally be missed.
Remote control requires explicit, ongoing consent. Agree on a stop signal and a comfortable range before connecting. The wearer should set channel-specific maximum intensity limits in LINX before starting; those limits remain visible to the remote controller and cannot be exceeded during that session. The wearer can change intensity from the device, press the power button momentarily to zero both outputs, or close the remote session. Never leave a person restrained, unattended or unable to end a connected session.
Safer setup sequence
- Charge LINX before use and inspect the controller, cables, plugs and electrodes for wear or damage.
- Read the LINX manual and the instructions for every connected accessory.
- With LINX off or both channels at zero, connect the cable and electrodes.
- Place electrodes only below the waist and only as the accessory instructions permit. Never route current across the chest, head or neck.
- Confirm the correct channel and controls before increasing intensity.
- Begin at zero and raise one channel gradually. A different accessory or placement may feel stronger at the same displayed level.
- Before removing any electrode, return its channel to zero or use the power-button zero function.
Do not use LINX if you have heart problems or an arrhythmia, a pacemaker or another implanted medical device, metallic surgical implants, epilepsy, pregnancy, existing pain, a relevant penile or anal disorder, or inflamed, swollen, broken or damaged skin. Stop immediately for pain, burning, numbness, dizziness, unexpected muscle contraction, bleeding or any sensation that feels wrong. This product is intended for consensual adult pleasure and does not diagnose, treat or prevent a medical condition.
Charging, cleaning and storage
ElectraStim documents less than an hour to roughly 80 percent from empty and up to three hours to reach 100 percent. LINX does not function as a stimulator while charging. The manufacturer lists a minimum two-hour, typical four-hour and maximum six-hour discharge time; actual use varies with intensity, mode, battery condition and connection behavior.
Clean the controller with a lightly dampened cloth only. Do not immerse it, use it in a bath or shower, or allow moisture into the USB-C port or output sockets. Clean reusable accessories according to their own instructions, let every component dry completely, and store the controller and leads in the included case without tightly kinking the cables. Our materials and care guide covers general cleaning boundaries, but the ElectraStim instructions control when they are more specific.
Choose the right electro-play setup
LINX is a high-specification choice for shoppers who want two independently adjustable outputs, stand-alone operation and both local and long-distance app control. If you are comparing control units, see all electro power units, the broader electrostimulation collection, or more products from ElectraStim.

LINX EM220 FAQ
Does LINX work without a phone?
Yes. Its stand-alone controls provide 11 wave patterns and 12 pulse patterns without an app or internet connection.
Can two people control it from different locations?
Yes, when both parties use the LINX app and have suitable internet connectivity. The wearer generates a temporary session code and should set intensity limits before handing over control.
Is LINX waterproof?
No waterproof or submersible claim should be assumed. The manufacturer instructs users to clean the unit only with a lightly dampened cloth, never immerse it, and keep moisture away from every socket and port.
How long does the battery last?
The manual documents a minimum of two hours, a typical four hours and a maximum of six hours. Mode, intensity, battery condition and wireless activity can change actual run time.
Can LINX be used as a medical device?
No. ElectraStim states that no medical claims are expressed or implied. Follow every contraindication and consult a qualified medical professional if you are unsure whether electro stimulation is appropriate for you.
