The 10 Best TENS Units for Pain Relief in 2024

Last Update:

If you’re looking for a way to alleviate pain or improve muscle function, a TENS unit may be just what you need. TENS (transcutaneous electrical nerve stimulation) units use electrical impulses to stimulate nerves and muscles, providing pain relief and muscle relaxation.

With so many options on the market, it can be difficult to determine which TENS unit is the best fit for your needs. In this article, we’ve compiled a list of the ten best TENS units available and detailed information about their features and benefits to help you make an informed decision. Whether you’re dealing with chronic pain or just looking to improve your physical well-being, we’ve got you covered.

What is a TENS unit?

A TENS (Transcutaneous Electrical Nerve Stimulation) unit is a small, portable, battery-operated device that provides pain relief through the application of electrical impulses to the skin. These electrical impulses are delivered through adhesive electrode pads placed on or near the area of pain.

The primary function of a TENS unit is to help manage pain by blocking pain signals from reaching the brain. It does this by stimulating the nerves in the affected area, which can help to override the pain signals and reduce the perception of pain. Additionally, TENS units may stimulate the production of endorphins, the body’s natural pain-relieving chemicals, further contributing to pain relief.

TENS units are often used to help alleviate acute and chronic pain, such as that caused by musculoskeletal issues, injury, or surgery. They are non-invasive, drug-free, and generally considered safe, making them appealing to many individuals seeking pain relief [1].

The Top 10 List

We have carefully evaluated and researched various TENS units to create a list of the top 10 options. Each product on our list has been reviewed for its features, effectiveness, and overall value.

iReliev TENS EMS Combination Unit

TENS Unit + EMS Muscle Stimulator by iReliev: Comes...

If you’re in search of a versatile wired TENS device that combines the benefits of two therapies in one package, the iReliev TENS and EMS unit could be an excellent choice for you. As a seasoned TENS unit user, I have found that this device offers many qualities you would expect from a top-tier TENS unit.

The iReliev TENS and EMS unit boasts dual-channel versatility, an adjustable timer, and 80 mA intensity. It provides 14 preset therapy modes, encompassing an Arthritis TENS mode, 7 TENS pain relief modes, and 6 EMS modes for muscle strength, conditioning, endurance, exercise warm-up, and recovery. The device is FDA-cleared, ensuring its quality and safety.

One of the standout features of this unit is its large 2.20-inch backlit screen, which facilitates easy reading and use, both during the day and at night. The compact and portable design allows it to fit comfortably in your pocket or attach to your clothes via a clip. The rechargeable lithium-ion battery eliminates the need for constant battery replacement, providing multiple sessions before requiring a recharge.

The pad quality is top-notch, and replacement pads are readily available for purchase, either on Amazon or directly through iReliev. In my experience, this TENS unit has consistently proven effective in dealing with muscle strains. However, as with many other TENS units, the wired design can sometimes be uncomfortable.

Overall, the iReliev TENS and EMS unit is ideal for those seeking a high-quality, portable, and well-designed TENS unit that won’t break the bank. It is suitable for use at home, work, or on the go, and the manufacturer even offers a full refund within 14 days if you’re not satisfied with your purchase.

HealthmateForever TENS Unit

HealthmateForever YK15AB TENS unit EMS Muscle...

While the HealthmateForever may not be the most high-end unit on the market, it provides numerous features at a lower price point, making it a great value.

One standout aspect of this device is its dual functionality as both a TENS and EMS unit, allowing you to use it for pain relief and muscle stimulation. With 15 modes available, including nine tailored to specific body parts and five massage modes (kneading, acupuncture, tapping, cupping, and scraping), as well as a random mode, you’re sure to find a setting that suits your needs.

Its large backlit LCD display shows the targeted area, massage type, and time remaining on the cycle, making it easy to operate. The device also offers high intensity, with four outputs providing the same 20 levels of intensity regardless of the number of outputs used simultaneously.

However, there are a few downsides to consider. The build quality may not be as sturdy as some other models on the market, and the instructions can be somewhat vague, making it more challenging to understand how to use the device. Some users might find even the lowest intensity setting too strong, and the unit’s size is larger than other TENS devices, potentially limiting its portability.

Despite these drawbacks, the HealthmateForever TENS unit remains an excellent value for the price. Its dual-channel system, versatile modes, and easy-to-read display make it an attractive choice for anyone looking for a budget-friendly, multifunctional TENS device.

Omron’s latest TENS unit, the Max Power Relief, has six pre-set pain modes and three massage modes, each featuring fifteen different power levels; it’s clear why Omron describes this as their most powerful TENS unit.

The Max Power Relief boasts an easy-to-use design with just three buttons, making controlling your pain relief straightforward. This device is also portable and can easily fit into a purse, carry-on, or backpack for convenient use whenever you need it.

However, the Max Power Relief stands out with its Long Life pads, which can last up to 150 uses. This sets it apart from competitors, as most other TENS unit pads require frequent replacement, meaning you’ll save money in the long run by not needing to replace the pads as often.

Omron is a well-respected health industry brand known for its blood pressure monitors and weighing scales. Therefore, finding replacement pads for the Max Power Relief should be hassle-free.

In summary, the Omron Max Power Relief is a top-rated TENS unit that delivers power, convenience, and cost savings, making it an excellent choice for effective pain relief.

Top Factors To Consider When Buying a TENS unit

  1. Intended Use: Determine the primary reason for purchasing the TENS unit. Is it for pain relief, muscle stimulation, or both? Look for a TENS unit that offers both TENS and EMS (Electrical Muscle Stimulation) functionality if you want to use the device for strength training or post-exercise recovery.
  2. Channels: The number of channels determines how many body areas can be treated simultaneously. A dual-channel TENS unit will allow you to simultaneously treat two parts of your body. If you require more electrode pads, look for a unit with more channels.
  3. Size and Portability: Consider the size and portability of the TENS unit, especially if you plan to use it on the go or during travel. A smaller and lighter unit may be more convenient.
  4. Battery Life: Look for a TENS unit with a long battery life, or one that uses rechargeable batteries or USB charging. This will impact the ongoing cost of using the device.
  5. Electrode Pads: Pay attention to the quality of the electrode pads that come with the TENS unit, as well as the availability of replacement pads. Look for a reputable brand offering high-quality pads that can be reused often.
  6. Therapy Modes: Consider the number of therapy modes the TENS unit offers. While more modes may not necessarily be better, having a variety of modes can cater to different types of pain.
  7. Intensity Levels: Look for a TENS unit with adjustable intensity levels, as different types of pain and certain body areas may require different intensity levels to alleviate pain.
  8. Guarantee: Consider the warranty or money-back guarantee offered by the manufacturer. This can be an indicator of a good quality product.
  9. Price: Compare the features and prices of different TENS units to find the best value for your money. Remember that being more expensive doesn’t necessarily mean the product is higher quality.
  10. TENS AND EMS combined: Look for a TENS unit that offers both TENS and EMS functionality if you want to use the device for both pain relief and muscle stimulation. This can be a cost-effective way to achieve both benefits with a single device.


In this section, we’ll go over some of the most frequently asked questions about TENS.

A TENS unit works by sending small electrical pulses through the skin to stimulate the nerves and reduce pain signals from reaching the brain.

TENS units can be used for many types of pain, including back, neck, and joint pain. However, it’s best to consult a healthcare professional to determine if TENS therapy is appropriate for your condition.

While there isn’t a lot of conclusive research on the effectiveness of TENS therapy, some studies have shown that it may provide pain relief for certain individuals [2]. However, the amount of pain relief and the duration of the relief can vary from person to person.

It’s also worth noting that while TENS therapy may provide initial relief for some people, it can become less effective after extended use. It’s important to view TENS therapy as a complementary method for managing pain in addition to other treatments and to consult with a healthcare professional before using it.

TENS units are generally safe to use when used correctly and as directed. However, certain individuals, such as those who suffer from epilepsy or heart problems, or wear a pacemaker or any metal or electrical implant, should avoid TENS therapy. TENS therapy is generally considered safe during pregnancy, but it’s best to consult a healthcare professional before using a TENS unit.

Some health insurance plans may cover TENS therapy, but coverage can vary. Check with your insurance provider to see if TENS therapy is covered under your plan.

The side effects of TENS therapy are generally minimal and may include skin irritation or mild muscle twitching. Consult with a healthcare professional if you experience any adverse effects.

The length of time to use a TENS unit can vary depending on the individual and the severity of the pain. Follow the manufacturer’s instructions and consult with a healthcare professional for guidance.

TENS and EMS are both forms of electrical stimulation therapy, but they serve different purposes.

TENS therapy is primarily used for pain management. It works by sending small electrical pulses through the skin to stimulate nerve fibres and reduce pain signals to the brain. TENS therapy is typically used for chronic pain, back pain, and arthritis.

On the other hand, EMS therapy is designed to stimulate muscle contractions. It works by sending electrical pulses through the skin to stimulate muscle fibres, causing them to contract and relax. EMS therapy is typically used for muscle strengthening and rehabilitation and is often used by athletes and physical therapists to aid recovery after injury.

While TENS and EMS units may look similar and use similar technology, they are designed for different purposes and should not be used interchangeably.
