This portable device fits comfortably in your hand or pocket, making it easy to use at home, at work, or on the go. Max Power Relief features six body pain modes (shoulder, lower back, arm, foot, leg, joint) and three massage-like modes (rub, tap, knead), each with 15 adjustable intensity levels, allowing you to personalize your therapy to your exact needs. Whether you're dealing with pain from daily activities or muscle soreness from exercise, this TENS unit delivers targeted, drug-free relief. The unit comes with a pair of comfortable, self-adhesive Long Life Pads that are reusable up to 150 times, along with a convenient plastic holder for storage. With its strength, flexibility, and portability, Max Power Relief is a smart choice for anyone looking to take control of their pain management. NOTE: To avoid damage to the device, use only with the leads, electrodes, and accessories recommended by OMRON. Review: Incredibly impressive - This little one is incredibly skilled at its job, so much so that it feels like it turns your home into a physiotherapy clinic. Don't hesitate to buy it. Review: Must have for lower back pain - I had a disk surgery and unfortunately once you have a disk issue, it stays with you. Been on pain killers for years. This device is simply amazing. I have been using it a month now and did not need pain killers at all. I use it 30 min a day and the pain either disappears or is very low. Absolutely recommend it to anyone with lower back pain or other pain. I can't believe why doctors don't reccomend these units. ## Features - Powerful Therapy: 2 times the power (compared to the OMRON Pocket Pain Pro TENS unit) makes it simple to find the right pain relief for multiple body areas - Customized Control: 6 body pain modes (shoulder, lower back, arm, foot, leg, joint) and 3 massage-like modes (rub, tap, knead), each with 15 adjustable levels of power intensity to help relieve your pain - Tens Technology: Scientific theory suggests that TENS technology blocks the pain signal from reaching the brain, increases blood circulation to targeted areas, and stimulates your body’s natural painkillers - Portable: Compact and easily fits into purse, carry-on, or briefcase for when you need it most - Convenient: User-friendly controls and a large display screen make for easy operation - Long Life Pads: Comfortable, self-adhesive TENS unit pads (1 pair) are reusable up to 150 times with plastic holder for storage ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00SVPNZXU | | ASIN | B00SVPNZXU | | Batteries | 2 AAA batteries required.

All alkaline and carbon batteries of this size are 1.5 volts each; using two produces 3.0 volts. Always avoid using rechargeable batteries if you want to have maximum power. **Q: What is the max electrical charge in mA?** A: The booklet says 70 volts at 500 ohms. Using the conversion factor of 1000 mA per volt, that means this unit has a maximum output of 70000 mA at 500 ohms (whatever that means). Considering the fact that the average TENS unit outputs about 80 mA, 70,000 mA seems like enough electricity to supply power to New York City for a week. I'm joking but that amount does seem extreme. Maybe someone with some knowledge of electricity can make sense of it. **Q: How long are the cords on the unit? I need it for lower calf pain and was wondering if they are long enough to fit under clothing to use at work.** A: They should be long enough to reach from the lower leg, up over your waste band and into your pocket. The unit is marvelous. **Q: Do I need to replace pad every time? Or between family member use?** A: No the pads get replaced only when they no longer will stick to the skin. I have used mine for over 50-75 times and they still stick, although I have rinsed them with water a few times. As for sharing between family members, I'd probably want my own set of pads. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Incredibly impressive *by M***T on 11 August 2024* This little one is incredibly skilled at its job, so much so that it feels like it turns your home into a physiotherapy clinic. Don't hesitate to buy it. ### ⭐⭐⭐⭐⭐ Must have for lower back pain *by E***P on 7 January 2020* I had a disk surgery and unfortunately once you have a disk issue, it stays with you. Been on pain killers for years. This device is simply amazing. I have been using it a month now and did not need pain killers at all. I use it 30 min a day and the pain either disappears or is very low. Absolutely recommend it to anyone with lower back pain or other pain. I can't believe why doctors don't reccomend these units. ### ⭐⭐⭐⭐⭐ Good Solution for Back Pain relief *by R***R on 7 April 2021* Using it since last 15 days, the build and performance quality is excellent. It acts as a good pain reliever for moderate pain, more power levels are desirable for alleviating higher pain levels. If you compare with the physiotherapist’s machine, this will fall short but by itself it is a good home pain relieving device. ## Frequently Bought Together - OMRON Max Power Relief TENS Unit Muscle Stimulator, Simulated Massage Therapy for Lower Back, Arm, Shoulder, Leg, Foot, and Arthritis Pain, Drug-Free Pain Relief (PM500) - 10 Pcs Durable Compatible with Omron Tens Unit Replacement Pads,5Pairs Replacement Electrotherapy Pads - OMRON Long Life Pads for OMRON TENS Unit - Pads for Electric Muscle Stimulator - Designed for Lower Back, Arm, Shoulder, Leg, and Foot --- ## 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.us/products/253300929-omron-max-power-relief-tens-unit-muscle-stimulator-simulated-massage](https://www.desertcart.us/products/253300929-omron-max-power-relief-tens-unit-muscle-stimulator-simulated-massage) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-25*
