## Description

iStim EV-805 4Channels TENS EMS electrotherapy Machine, Muscle Stimulator, TENS Machine for Back Pain, Nerve Pain Relief, Muscle & Nerve stimulators, EMS Machine Muscle Building, 16 Pads, AA Battery : desertcart.co.uk: Health & Personal Care

Review: iSTIM EV-805: Simple, Strong, Effective - The iSTIM EV-805 machine features four channels, allowing the simultaneous use of eight electrode pads. At first glance, the numerous buttons and wires might seem daunting, but in reality, it's quite user-friendly. My suggestion is to start by using 1-2 channels. Once you become more comfortable, you can utilize all four channels at once. This capability to relieve and train multiple muscle areas simultaneously is incredibly convenient. After workouts, I often experience soreness in multiple areas, and with this device, I can apply pads to both my knees and shoulders. The wire length is sufficient to place them anywhere on the body, as long as it's not prohibited. Remember not to place pads on the face or head. For beginners, I recommend turning on the device and pressing the MODE button until you see the "P" indicator. You can then choose from the preset programs P1 to P24, adjusting only the intensity. If you're already familiar with using such devices, the impressive aspect of this machine is that the pulse rate and width are adjustable, allowing for various modes and tests. I highly recommend purchasing this machine due to its powerful and convenient features. However, a drawback is that it is not rechargeable and requires four AA batteries. Fortunately, these batteries are included in the package, so there's no need to purchase them separately initially.
Review: Excellent performance - This works great on my neck and back, I love the different options and levels. Easy to use and adjust when needed. Great quality and good performance. Good support for body pain relief.

## Features

- ✨ TENS for Nerve Pain Relief – Used by Professionals : A non-invasive, drug-free electrotherapy method commonly used by physiotherapists. TENS delivers gentle pulses through the skin to stimulate nerve fibres and help block pain signals. Often used in sciatica pain relief products and suitable for managing chronic and acute discomfort—such as back tension, muscle soreness, and joint stiffness.
- ✨ EMS for Muscle Recovery & Strengthening : Internationally recognized for treating muscle injuries and promoting muscle strengthening. EMS activates muscles through electrical impulses to support recovery and improve muscle tone. Popular for relieving fatigue or maintaining strength — especially among active adults or long sitting professionals.
- ✨4-Channel TENS EMS Combo Machine: The iSTIM EV-805 features 5 TENS modes, 3 EMS modes, and 24 pre-set programs(P1-P12 for TENS, P13-P24 for EMS). With intensity levels 1–100 and 4 independent channels, you can treat multiple areas at once for customised relief and relaxation.
- ✨ Complete Kit – Ready to Use with AA Batteries: TENS + EMS Combo Unit x 1 Electrode Pads x 16 (2 Types: 2”x2” + 2”x4”) Lead Wires x 4 Instruction Manual x 1 Pad Guide x 1 AA Batteries x 4 Paper Case x 1 ⚠️ Note: This model is powered by AA batteries, meaning there is no charging unit included. It is ready to use straight out of the box with no need for additional charging or setup. Packed in a clean white iStim paper case.
- ✨Includes 16 Reusable Electrode Pads: Comes with 16 self-adhesive pads in two sizes (2”x2” and 2”x4”). Use up to 8 pads simultaneously to target different body areas like shoulders, back, and knees. Durable and gentle on the skin. Provides effective relief and support for any areas you need to soothe or strengthen. ✅ Compatible replacement pads for use with TENS and EMS machines using standard 2 mm pin connectors — such as those from Auvon, iStim, TensCare, MedFit, Body Clock, Axion, and Roscoe TENS 7000. ⚠️ Please note: Compatibility may vary by model. Always confirm your device uses 2 mm pigtail-style lead wires before use.
