This is a review of the 10 best TENS Units for dealing with pain in 2022.

When selecting the best TENS unit for personal use you’re going to want something that’s light, easy to use as well as effective in helping relieve pain.

I’ve been through my fair share of TENS units and these are the factors that can make the difference between your TENS unit being a chore to use or a pleasurable experience. 

There are many decent TENS units on the market, however, I decided that the best overall TENS unit is the iReliev TENS + EMS Combination Unit.

Note that this is the best overall choice, and there may be other TENS units that are better suited to your own needs. 

But do not fear, because I’ve also laid out a whole range of different options you can select from in order to find the perfect TENS unit for you.

Let’s begin.

TENS Unit Buying Guide

q? encoding=UTF8&ASIN=B01MXSPBUW&Format= SL160 &ID=AsinImage&MarketPlace=US&ServiceVersion=20070822&WS=1&tag=tensunit0b 20&language=en US

If you’ve never used or purchased a TENS device before, the process might seem a bit daunting – especially with so many options now available.

Well, to make your life easier I’ve shared some of the best features to look for when choosing the best TENS unit for you.

Size and Weight

Given that most TENS devices are small and portable, many people use them while on the move or when they are working.

If you don’t want your TENS unit to keep you chained to one place due to how large it is, the smaller and lighter it is the better.

Some units can be attached to clothing, clipped onto a belt or held in a trouser pocket.

Generally, when choosing a TENS unit the smaller and lighter it is the better.

Battery or USB rechargeable

Typically TENS units are battery-powered or have a rechargeable battery that can be charged via USB.  

If you don’t want the hassle of having to always have a spare supply of backup batteries then the USB charged TENS unit will be a better choice.

Number of Channels

A channel is an outlet on a TENS unit where you plug in a lead wire. A lead wire will usually branch out into two electrodes.

This means if you purchase a single channel TENS unit you will only be able to use two electrode pads.

A dual-channel TENS unit will allow you to have two lead wires inserted into the unit meaning you can have four electrode pads.

Personally, I’ve found that dual channel TENS units provide the optimal amount of electrode pads. 

Wired or Wireless TENS Unit

Currently, most TENS units are wired, meaning that the TENS unit has wires running from the device all the way down to each pad.

A wireless TENS unit is as it sounds – there are no wires at all running between the unit and the pads.

While wired units are the norm there are also a greater number of wireless models that are now appearing on the market.

However, they are more expensive.

That being said, I cannot emphasize how much more enjoyable it is to use a wireless model over a wired model.

A wired TENS unit will always get its wires tangled no matter how organised you try to keep things and having multiple wires running all over your body doesn’t help either.

So if you have the extra budget a wireless TENS unit is the way to go. 

Electrode Pads

TENS unit gel pads

You not only want to pay attention to the quality of the main device, but also the electrode pads that come with the TENS unit.

Pad Quality

Different TENS units will come packaged with their own brand of pads.

Some models will give you more supplementary pads that come in all kinds of shapes and sizes than other brands.  

This may be an important factor depending on the part of the body you plan to use them on.

However, what is most important is the quality of the pads.

A quality pad should be able to be reused many times and not lose its stickiness too quickly.

The better the quality of the pad the less deterioration it takes and the less stickiness it loses over time.

Owning a TENS unit with a better quality pad means you save money from having to keep replacing the pads all the time.

Pad Availability 

Another factor to consider is the availability of replacement pads.

How easy is it to buy replacement pads?

The last thing you want is your TENS unit brand to either go bust or decide not to make their pads available anymore.

Be sure to select a TENS unit that is made by a reputable brand that plans to stick around for the long haul.

Therapy Modes

Some TENS devices come with different therapy modes which mimic different types of massages and different rhythms. 

More does not mean better.

In fact, sometimes I found that too many of the modes felt the same and I couldn’t tell the difference.

So for some people, a high number of therapy modes may not be necessary and may even make the whole process overly complex.

Some of the TENS devices I have come across come with 24 of these modes.

Does this seem like overkill to you?

You will need to decide whether these modes are of benefit to you or not.

If you don’t need that many then you can buy a simpler TENS unit and save some money in the process.

Personally, I found that around 10 of these modes are plenty.

Intensity Levels

This is important because different types of pains and certain areas of the body will require a different intensity level to alleviate the pain.

For example, you will likely require a higher level of intensity for back pain as opposed to neck pain.

Having a higher number of intensity levels is usually better because you’ll better be able to find the perfect intensity you need for whichever body part you are working on.

That being said, keep in mind that more intensity modes on a TENS unit does not necessarily mean more power.

Guarantee

Since TENS devices are likely to be with you for most of the day they should be built in a way that they won’t break the first time you drop them.

The material used to make the product is not always displayed in the description, but a money-back guarantee or some kind of warranty is an indicator of a good product.

Price

Prices can range from about 30 bucks on the lower end, to over 300 dollars.

Keep in mind that being more expensive doesn’t necessarily mean that the product is a good buy, but many of the best TENS devices are indeed on the higher end of the budget.

Compare the low and high-end options and look at the features that account for the price of the item, and then choose something that offers the best features and work within your budget.

TENS AND EMS combined

A lot of the TENS units now come with TENS and electrical muscle stimulation (EMS) functionality combined.

If you not only want to use your device to manage your pain but also get the benefits of EMS, then look for a machine that combines bother types of stimulation.

The EMS can aid in strength training and even act as a rehab tool while offering post-exercise recovery benefits for athletes.

In this section, I’ll look at the best TENS units that are available for home use.

Everyone has different preferences so make sure you know what yours are and that you select the best device to meet those needs.

This portable, lightweight device is ideal for home, work or travel and if you’re not satisfied with your purchase you can return it within 14 days for a full refund.

It has 15 modes which include 9 for different body parts and 5 massage modes (knead, acupuncture, tapping, cupping, scraping) and one random mode.

If you want bang for your buck then the HealthmateForever TENS unit is a viable option for you.

Omron has described this as their most powerful TENS unit to date which will attract many buyers looking for a powerful yet compact unit.

This model is easy to use and simple to control with only 3 buttons on the unit.

One potential drawback is that it requires 2 AA batteries unlike some other units on this list which are fully rechargeable.

In addition, the screen on the Max Power Relief unit is not backlit so it may not be as easy to read as some other TENS units on the market.

Where it does excel is its Long Life pads which can be used up to 150 times.

This is far more than most other competitor pads and you’ll find yourself saving heavily on pads in the future as they don’t need replacing as frequently as other models.

All in all the Omron Max Power is a popular TENS unit that packs a lot of power.

I’ve taken it for a test and the power and response is exactly the same as the Wired version.

If you have the extra budget, then the iReliev Wireless TENS Unit is the best TENS unit of them all.

The Benefit Of TENS 

YouTube video

If you’ve never used a TENS unit before, you might be wondering if it’s really worth investing in.

TENS machines have their benefits and are being used in countries around the world to treat varied pain-related conditions such as back pain and other chronic pain.

Some of the benefits include:

Aids in Muscle Recovery and Relaxation

Some units are designed to help athletes or persons who engage in daily exercise regimens and suffer from muscle aches and pain.

A 2007 research, published in the Journal of Clinical Science concluded that TENS was effective in treating delayed onset muscle soreness (DOMS).

Produces Endorphins

These are described as the natural painkillers in your body.

When you attach a TENS unit to your skin, the electrical stimulation impulses can signal these hormones in the brain for your body to produce endorphins to further aid in pain relief.

Minimal Side Effects

Unlike many other pain management treatments which often have several side effects (some worse than the pain itself) TENS does not.

There have been a few instances where users had allergic reactions to the pads that attach to the skin, so if you have allergies you may want to pay special attention to the type of material used in these pads.

Portable and User-Friendly

The TENS machines are smaller than many cell phones and can easily fit in your pocket or small bag.

Due to the size and lightweight factor you can also travel with the device from home to work or even take it with you on vacation.

This is perfect for someone who always suffers from back pain.

Offers Longevity

Unlike pills or injections that can wear off over time the TENS unit offers a long-term solution for pain relief and chronic pain.

These devices are meant to last for several years with proper care.

FAQ

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

What is TENS?

The abbreviation TENS, means transcutaneous electrical nerve stimulation, which is a form of treatment that can help ease pain and bring pain relief in areas of the body that ache.

This kind of treatment is achieved via a TENS device.

What is a TENS unit?

It is a small, battery-operated, electronic machine with adjustable settings.

Attached to the device are electrodes that look like tiny cords with small adhesive pads at the end of each one.

The pads are stuck onto the body above the aching areas.

Once the pads are stuck on, the TENS unit will send small electrical currents to stimulate the nerve endings to the areas of the body under the pads.

How does a TENS unit work?

To use a TENS unit first, attach the adhesive pads to the area on your body surrounding the painful area.

Once attached, you then turn on the unit and set the appropriate level of intensity that you require.

The machine transmits electrical currents which travel through the electrodes.

These electrical currents or impulses then inundate the nervous system ultimately decreasing its ability to send pain signals to your brain.

Do TENS units work?

A study published by the US National Library of Medicine shows that TENS can indeed prove effective in lowering or blocking pain signals travelling to the brain.

Additionally, depending on the frequency of the unit, the electrodes can cause your body to release endorphins, which act as natural pain relievers providing pain relief.

That being said, there are some people who find that a TENS unit doesn’t seem to help them. Results may vary.

What can TENS help with?

A TENS unit is best used only for short-term pain relief and is not intended to deal as a permanent remedy for chronic pain.

A TENS unit can be used to treat joint, neck and back pain, post-operative pain, period pain, migraines and even labour pain.

Furthermore, if you suffer from pain due to multiple sclerosis, endometriosis, arthritis, fibromyalgia or sport-related injuries, it might also prove helpful.

TENS units are not meant to treat every type of pain.

If you are unsure about anything, consult a professional who will be better able to guide you.

Is using a TENS unit safe?

This pain management treatment is safe and non-invasive and there are no major side effects; some devices offer pain relief for up to 24 hours.

It is recommended that you refrain from using a TENS unit if you suffer from epilepsy, heart problems, or if you wear a pacemaker or any metal or electrical implant. [1]

Additionally, if you are pregnant do not use the device on/around the abdomen or pelvic regions.

You may also need to check to see if the pads include any material which may cause irritation or an allergic reaction.

How often can you use a TENS unit?

There’s no hard rule on how many times a day or for how long you should use a TENS unit.

Some experts say you can use a TENS unit all day as long as it is safe to do so i.e. you are not showering or driving etc. [2].

However, guidance can vary so it’s best to either refer to the instruction manual of the device or ask your doctor.

What’s the difference between TENS and EMS?

If you’ve already heard of TENS, you may have come across the similar term EMS (electrical muscle stimulation). The two are often confused.

Both use electrical pulses to target areas of the body, but the difference between the two is in their names.

Whilst the TENS will target nerves, EMS targets muscles.

EMS therapy is more focused on muscle stimulation often used in sports recovery and increasing performance.

Which is the best TENS unit?

The iReliev TENS + EMS Combination Unit is the best overall TENS unit due to its effectiveness, portability and quality.
