The Therapy TENS Unit 4 is the fourth-generation evolution of our flagship TENS device. Designed in Denver, Colorado by a team of engineers, doctors, and scientists, every detail was refined with one goal: to create the highest-quality, easiest-to-use TENS unit possible—delivering a powerful, deep pulse on par with professional physical therapy devices.
Built using premium components sourced from around the world, the Therapy TENS Unit 4 combines advanced technology with exceptional reliability and ease of use. Its intuitive touchscreen interface makes treatment simple, while precision-engineered electronics and high-quality reusable self-adhesive gel electrode pads deliver comfortable, effective therapy session after session.
Professional-Grade Power
Almost all TENS devices on the market simply don't have the intensity to reach beyond the surface — they stimulate only the top layer of muscle, barely making a dent in real pain. That's especially true of wireless TENS units, which rely on small batteries built into the pads themselves — too small to deliver real power. Therapy TENS 4™ is different. Powered by our 6000mAh battery, it drives powerful current deep through the muscle and to the nerve level, delivering soothing pulses that cut through even stubborn, chronic pain for relief you can actually feel.
With 20 levels of intensity — from gentle to powerful — Therapy TENS 4™ matches the strength and settings used in professional settings like chiropractic offices, physical therapy clinics, and doctor's offices. This is the power difference that sets it apart.
Independent Dual Channels & All-Day Power
Unlike most TENS units on the market, Therapy TENS 4™ features two independent outputs — A and B — letting you run separate intensities and modes on each channel at the same time. It's powered by a best-in-class 6000mAh internal rechargeable battery, delivering up to 20 hours of continuous use on a single charge. And everything you need to get started is included right in the box.
Lifetime Warranty & Trusted by Professionals
Therapy TENS 4™ is FDA-cleared and trusted by over 200,000 patients, doctors, and chiropractors worldwide — safe, effective, and 100% drug-free. Every unit is backed by our lifetime warranty, a level of protection few companies can match.

I have only one word for this. Awesome and I would very highly recommend this to any one who is experiencing any type of back, neck or sciatic pain etc. The intensity levels are out of this world.
I have used several tens units over the last 10 years and I've done a lot of research. Therapy TENS 4 is the best TENS unit I've used. The unit is small, device is very user-friendly and most important has a lot of power.
Therapy TENS 4 has more intensity and power than other tens units I have used. The touch screen is large and easy to use, the pads are high quality, I love the rechargeable battery, up to 10 hours of use in one charge. I would recommend it to anybody.
Like many other reviewers, I found the Therapy TENS Unit 4 to be in a completely different league than the $119.40 model sold on another website. While the devices may appear alike on the outside, the technology inside is not even close. The Therapy TENS Unit 4 delivers significantly stronger, smoother, and deeper pulses, using far more advanced engineering. The cheaper models might win on appearance, but this one wins where it actually matters—in performance, pain relief, and long-term effectiveness.
I have tried several TENS units before, but none of them gave me the relief I needed for my chronic pain. Then I discovered this TENS unit, and I was amazed by the difference. This TENS unit works deep into the muscle, unlike other TENS units that only work the outside of the muscle and dont get anything done. This TENS unit has helped me reduce my pain medication and improve my mobility and quality of life. I recommend this unit to anyone who suffers from pain and wants a natural and effective solution.

I have a drawer full of tens units. I’ve tried the 7000 and several others from Amazon, but none of them work as good as this one.

I’ve tried both the Therapy TENS 4 and another unit that costs $119.40 on another online store, and the difference is night and day. When you hold them, the quality of the Therapy TENS 4 is immediately noticeable—sturdier, better built, and just feels premium.
The $119.40 unit has thin pads that barely stick, wear out quickly, and its wires at the bottom can slip out, shutting the machine off. When you plug them back in, it can even shock you. The screen is overly complicated and confusing, unlike the Therapy TENS 4 which is simple—you just pick a mode and adjust the intensity. On top of that, with the $119.40 unit, calls go to a call center in India.
Finally, the quality of the therapy with the Therapy TENS 4 is far superior, delivering more effective, consistent relief compared to the $119.40 unit.
I purchased a Therapy TENS Unit 4 at a physical therapy trade show convention. I'm really impressed with the quality of this TENS unit. I've had other TENS units in the past that didn't have a lot of power or options. This is the best unit on the market!
Therapy TENS was recommended by a chiropractor friend. I've been using it for about 3 weeks now everyday and I love it. Great for pain relief and rehabilitation!
I tried the butterfly-shaped wireless TENS unit for my lower back, but it wasn’t a great experience. The large pad wore out quickly, and because of its size, it was hard to position it exactly where I needed it. The unit itself felt bulky since the battery is attached to the pad, making it uncomfortable and prone to falling off. It also seemed weaker because of the small battery.
In contrast, the therapy TENS unit worked so much better. You can place the pads exactly where you need them, and it allows you to use four pads at once on different channels. This means you can adjust the intensity—for example, stronger on the lower pads and lighter on the upper ones—which makes a huge difference. The pads also seem to have better conductivity, and the current feels much stronger and more effective.
The problem with other units out there is they don't have enough intensity. They can't work the big muscle groups in your back and neck. Don't waste your time with other units, this unit has all the power you need.
Works as good as the TENS unit at my physical therapy office. Great value.
By far a superior product to any other on the market, and a better value.
I'm happy I found this unit! You can really feel the current flowing. I've used several other tens units where you can barely feel the current.
The Therapy TENS 4 delivers outstanding performance and has truly elevated our approach to pain management. I was so impressed that I ended up purchasing two – one for my patients' home use and another for my clinic. The results have been remarkable. This device has become an invaluable tool in our treatment plans, providing optimal relief and enhancing the overall recovery process. If you're seeking a reliable, high-performance solution for pain management, don't hesitate to integrate this device into your journey.
I was skeptical at first, but this TENS unit blew me away. The intense but smooth stimulation it provided completely surpassed my expectations.
I can’t say enough about how user-friendly this TENS unit is! The large, high-definition touchscreen is a game-changer – switching between modes and adjusting settings is effortless, even if you’re not tech-savvy. No more tiny buttons or confusing menus! But what really stands out is the power behind this device. Unlike other TENS units I’ve tried that barely seem to make a difference, this one delivers strong, targeted muscle stimulation that you can actually feel working. It’s like having a deep muscle massage whenever you need it. Perfect for anyone looking for serious relief!
I spent a lot of time researching TENS units, and I’m thrilled I landed on this one! What truly sets it apart are the 20 different intensity levels. You can really feel the difference as the device works deeply to stimulate your muscles, not just lightly, but enough to make them twitch. If you've ever felt like other units fall short, this one delivers the power you need for real relief. Plus, the large digital touchscreen is fantastic – easy to navigate and read, even when you’re on the go. This device checks all the boxes for power, ease of use, and quality. Highly recommend!
I suffered from debilitating shoulder pain until I discovered the power of this TENS unit. Its deep-reaching pulses worked wonders on my muscles and joints.
Over 35 years of dealing with back problems, I've tried over a dozen different tens units. What distinguishes Therapy tens unit 4 isn't just the power, but also the quality of stimulation. This device combines TENS and EMS simultaneously, delivering superior stimulation. As far as I know, it's the only portable unit offering this. Comparable stimulation quality is found only in machines used by doctors and chiropractors.
They spent a lot of time working on the different modes. They have several patents on their modes. They are intricate and they really work. The acupuncture mode is very nice.
Therapy TENS has been an incredible solution for my sciatica struggles. Unlike other units I've tried, the therapy TENS 4 current reaches far into my back muscles soothes the nerve, offering unparalleled relief. This device has effectively addressed the root of my problems and provided lasting improvement. I can confidently say that Therapy TENS 4 surpasses any other unit I've encountered, delivering targeted therapy that truly alleviates my sciatic discomfort. I tried the wireless TENS units with a single large pad, but I found them frustrating because I couldn't place the pad in the exact spot that needed treatment and the pulse was too weak.
I returned two other TENS units before I found this one. Don't hesitate this device is legit. Thank you to the customer service team for answering all my questions.
I had almost given up hope of finding a solution for my persistent sciatica pain until I discovered this TENS unit. After trying multiple other units without success, I was amazed at the results this unit provided. Its powerful pulses specifically targeted my sciatic nerve, offering immense relief and finally healing my sciatica. I'm forever grateful for this remarkable device.
After countless attempts with other TENS units to alleviate my chronic neck pain, I was skeptical about trying another. However, this TENS unit proved me wrong. Its unique combination of targeted and powerful stimulation directly addressed my neck pain, bringing about significant healing.
The modes on this thing are incredible. Try mode number 6 and number 9 they will blow your mind.
The shipping was fast, thank God because I needed this. Once you find the right mode with the right intensity it's like magic!
I'm a professional, I've been in the physical therapy business for 20 years. I have used several TENS/EMS units over the years but this one is the best one I've used. Excellent value for the money!
There are a lot of knock-offs out there that look similar to this product but do not perform the same.
