By delivering stable pulses to the skin to stimulate nerve fibers, the Tens unit could effectively block the pain signal in people’s brains. - ✨EMS: “Electrical Muscle Stimulation” is an internationally accepted way of treating muscular injuries. It works by sending electronic pulses to the muscle needing treatment; this causes the muscle to exercise passively. When the muscle receives this signal, it contracts as if the brain has sent the signal itself. As the signal strength increases, the muscle flexes as in physical exercise. - ✨iSTIM EV-804: Digital TENS EMS combo stimulator comes with 2 channels, 5 TENS modes 2 EMS modes and 12Preset programs, sending comfortable impulses through the skin that stimulate the nerve fibers in the treatment area.

Simple and effective. *by on Reviewed in the United Kingdom 14 April 2026* I purchased this on the advice of my GP to help with my mobility and pain management. At my age, finding a safe and non-invasive treatment is crucial. I use the EMS mode daily to keep my leg muscles active and fight off weakness, while the TENS mode is absolutely brilliant for melting away my neck and shoulder tension. The machine feels very sturdy, and adjusting the intensity via the rotary dials is incredibly intuitive and safe. It’s a powerful little gadget that has genuinely improved my day-to-day comfort. Highly recommend it to any seniors struggling with similar aches! ### ⭐⭐⭐⭐⭐ It's fantastic - must have device. *by on Reviewed in the United Kingdom 27 June 2026* It's fantastic!AUVON I had it for 2 years before this - very decent device. Who understands how such devices work - iStim EV-804 - these are truly professional solutions. With 30 software settings plus manual installation, you can literally customize everything. Combined with a very powerful impulse (according to my rough calculations, it is somewhere twice as strong as my previous AUVON) - this is simply a fantastic device. I work as a groundworker and I know what it’s like to suffer from seasonal pains, wind pains, and weather changes pains - it's really do miracle recovery and taking off pains. Thank you! ### ⭐⭐⭐⭐⭐ Minor Flaws but Overall a Great TENS EMS Device *by on Reviewed in the United Kingdom 18 June 2024* I've been using TENS EMS devices for years. My old one was thinner and had a touchscreen. I once put it in my back pocket during a trip, and the screen went black. So this time, I got a button-operated device without a touchscreen. I love its color and timer, but you can't set the time in the built-in modes from P1 to P24. The power and effectiveness are great, though the buttons can be a bit unresponsive.PerformanceThis device is fantastic for pain relief. I bought it for my osteoarthritis and use it on my knees before long walks. It's hard to believe such a small machine can output so much power through four electrodes. The belt clip is handy. The black design looks cool and doesn't feel cheap. Unlike other brands, I need extra breathable tape to secure it, but it works really well.Battery LifeThe battery life is impressive. I've used it for two months, half an hour to an hour each time, and the battery is still strong. The downside is it's not rechargeable. It comes with a 9V battery, but you'll need to buy replacements when it runs out. ## Frequently Bought Together - iSTIM EV-804 TENS/EMS 2 Channel Rechargeable Combo Machine Unit - Muscle Stimulator + Back Pain Relief and Management- 7 modes/24 Programs/Backlit (Including Electrodes Pads) - iStim Super Soft 2"x2" TENS Unit Electrodes for TENS Massage EMS Unit/Muscle Stimulator - 100% Japanese Gel - 16 Pieces Reusable Electrode Pads (2"x2"- 16 Pieces - Black) - Spectra 360 Premium Electrode Gel for ECG, TENS, Monitoring, Pediatrics Soothing Gel Anti-Irritation 8.5 oz Tube - Each --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/530513934-istim-ev-804-tens-ems-2-channel-combo-machine-unit](https://www.desertcart.pt/products/530513934-istim-ev-804-tens-ems-2-channel-combo-machine-unit) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-05*
