Relief Wave 4™ is a powerful modern TENS unit and Electronic Muscle Stimulator that utilizes the latest technology. Relief Wave 4 provides you with relief from acute and chronic pain. What sets Relief Wave 4 apart from the competition is the powerful intensity of the pulse. Almost all other portable TENS units on the market do not have the proper power / intensity to work large muscle groups. Relief Wave 4 has 20 levels of intensity ranging from low intensity to very powerful, the same strength and settings as devices used in clinical settings like doctor’s offices, chiropractors, and physical therapists. 

Relief Wave 4 has 16 different modes and a premium internal rechargeable battery that can go up to 10 hours of continuous use. Also, Relief Wave 4 features dual independent outputs A and B, allowing you to use a different level of intensity and mode on each channel. This is the ultimate portable TENS / EMS unit with all of the premium features. The package comes with everything you need to get started right away!

For over 12 years Relief Wave has innovated and designed the best TENS units on the market. We have done it again, we heard your feedback and our newly designed FDA approved Relief Wave 4™ has an enhanced larger LCD screen, redesigned menus for ease-of-use, a larger premium battery for 10 hours of continuous use, high-quality long-lasting reusable gel pads, 20 levels of intensity, and it is small enough to fit in your pocket
