ElectraStim’s Linx (EM220) is their first proper leap into Bluetooth control — a high-spec, dual-output e‑stim box that works perfectly well on its own, but really comes alive when you pair it to the free Linx phone app. If you like the idea of building sessions, saving patterns, or handing control to a partner (including long-distance), this is the one in their range that’s built for it.

What it does (and why it’s different)

At heart, Linx is a dual-channel stimulator with 99 intensity levels per channel, so you can balance two separate circuits properly instead of just “more/less”. Out of the box, it’s loaded with 23 patterns (11 Wave + 12 Pulse) for stand‑alone play — and it starts at zero intensity when powered on, which is exactly how we like a serious box to behave.

Pair it to the mobile app over Bluetooth, and you unlock the wider toybox: extra play modes such as Flick, Tilt, Stereo Stim and Playlists, plus options for more hands-on control. The Playlist feature is particularly interesting: you can build longer sessions by combining “snippets” with adjustable timing and feel, rather than being stuck with a single loop forever.

There’s also a Remote Control mode, where a partner can take over patterns and intensity in real time from anywhere, using a shared access code. No extra hardware needed — it’s baked into the system.

Practical bits

• USB‑C rechargeable (around 3 hours for a full charge, up to 6 hours play depending on how hard you run it)
• Clear OLED display and on-device controls for intensity and basic mode selection
• Designed to run one bipolar electrode per channel or two uni‑polar electrodes per channel (so you can set up two separate areas with independent control)

What’s in the bag

Linx isn’t a “box only” situation — it ships as a kit:

• 1× ElectraStim Linx Electro Stimulator (EM220)
• 1× Zipped protective storage case
• 1× Detachable belt clip
• 4× Self‑adhesive ElectraPads (EM2118)
• 2× Connecting cables with 2mm pin connectors
• 1× USB‑C charging cable
• Extended warranty card
• Quick-start guide

Who it’s suited for

Linx is aimed at people who want more control and more options than a basic powerbox:

• Experienced users looking for deeper, stronger stimulation with premium accessories (the 99-step control per channel is genuinely useful here).
• Anyone into pattern play and longer sessions — especially if you like the idea of building and saving a “routine” rather than scrolling endlessly.
• Couples (or long-distance partners) who want real remote control, not just “hold this and press a button”.

If you’re the sort of person who never wants an app anywhere near your kink, Linx may be overkill — but if Bluetooth control and remote play sound like features rather than threats, this is ElectraStim’s most modern box to date.

Phone Compatibility

To get the most out of Linx, your device should support Bluetooth Low Energy (BLE) 5.0 or higher. This provides the most reliable connection, improved responsiveness and the best overall performance for specific features such as long-range or high-speed modes.

If you’re unsure which Bluetooth version your device uses, you can find this in your device settings (typically under About device) or by searching your model name online.
