Therapy TENS Unit 4 Touch Screen Powerful Electronic Pulse Muscle Stimulator

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.
