Five e-stim platforms, compared by architecture rather than hype
The devices below come from different product families. This matrix highlights documented differences without treating a longer feature list as an automatic winner.
| Category | MK-312BT | ZC95 MKII | ET312B | E-Stim 2B | Tension Lover 2 |
|---|---|---|---|---|---|
| Design concept | Modern 312-inspired dual-channel platform | Four-channel programmable platform with 312 influence | Original ErosTek reference platform | Independent dual-channel e-stim system | Compact parameter-focused stimulator |
| Channels | 2 | 4 isolated | 2 | 2 isolated | 2 independently adjustable |
| Wireless / remote | Bluetooth | Bluetooth + Wi-Fi | Traditional link interface rather than modern wireless | Optional computer link | No comparable remote-control platform |
| Audio functions | Yes | Line / microphone input | Audio capability | Stereo audio + microphone | Not a central feature |
| Patterns / modes | 18+ stated by seller | 14 built in + Lua possibilities | Digital patterns | 17 program modes | 7 stimulation + 3 training modes |
| User scripting | Depends on implementation | Lua scripting | No comparable built-in scripting | Sessions can be used through link software | No |
| Power approach | 2.3 Ah rechargeable battery in Stim-System version | 26650 cell / USB-C | Legacy original hardware | 9 V battery or external supply | Rechargeable / USB-C |
| Primary appeal | Two-channel 312-style operation with Bluetooth | Four channels, remote control and programmability | Historical benchmark | Established two-channel audio/link ecosystem | Compact operation and conventional pulse parameters |
How to read the table
MK-312BT is centered on maintaining a familiar two-channel 312-style experience in current hardware. ZC95 MKII expands into four channels and deeper software control. E-Stim Systems 2B follows its own mature ecosystem with audio and link functions. Tension Lover 2 is the compact, more conventional option in this group. ET312B is mainly the historical reference against which later 312-inspired devices are understood.
Connector standards, accessories, control layout and personal workflow can matter just as much as channel count or software features. Verify compatibility before mixing accessories between platforms.
