It also includes 5 automated massage programs, and 3 traditional massage modes, to get rid of all that stress and soreness from working out.

The rechargeable lithium-ion battery is extremely convenient, and can be recharged with either a DC or USB connection, which most of us have within our vicinity at any given point in time. The portable device comes in a little carry storage bag, so you have everything you need, too.

The user-friendly design makes it fast and straightforward to learn, as all you have to do Is push the buttons. The treatment time is clearly displayed on the backlit LCD screen, and you can choose between the auto program and intensity level right there.

You only have to place one pad on the affected area, and you’re ready to go. With that being said, if you use two wireless pods and pads with this unit, it would be like using 4 on your regular dual channel device.

You can set treatment times anywhere from 5-60 minutes, and they’re set independently for each channel. With 25 intensity levels, you have quite a bit of control and variation over how intense you’d like your treatment to be.

Due to the dual channels, you can use it on two body parts simultaneously, saving you time, and even bettering potential results. With 20 intensity levels, it’s not as many as some others, but it’s definitely more than sufficient for most TENS machines.

We used each one individually, and in-depth, to ensure that they were satisfactory, and high-performing enough to make our list. However, not every one is going to be the right one for you and your needs, so we’ve written unbiased reviews on each, in an effort to help you select the perfect, best TENS unit and muscle stimulator.

Now, we’re going to take you through our in-depth buying guide to ensure you know exactly what to look for, ultimately choosing the best TENS unit for you and your body’s needs.

It can be overwhelming if you’ve never used a TENS machine to read about all the different programs and modes a machine comes with. Where do you even begin? Most units feature preset programs, designed to make the process simpler for you.

You’ll want to take into consideration which modes/programs each one has, and what they accomplish. Don’t just get a machine that has a cool-sounding mode that you may use once. Some feature less modes, but allow you the flexibility of really narrowing down and customizing your treatment.

With that, keep in mind that just because a machine has a higher number of modes, doesn’t mean it’s better, or is going to be the best one for you.

Number of Channels

You’ll find in the products above that most have dual channels, which give you the ability to use two independent pads, with independent controls. This means you can choose to use it with either two or four pads simultaneously.

This is great if you want to treat multiple parts of the body at the same time. As there’s rarely a notable difference in price between single and dual channels, there’s nothing to be lost on choosing a dual channel device.

Intensity Levels

You may have noticed that products vary in the number of intensity levels. How many do you really need, though? That solely depends on you. If a machine features 40 intensity levels, and another has only 20, that doesn’t necessarily make the former the better choice.

Typically, this only means that you can better fine-tune it, as machines that have more levels are going to increase in smaller increments than one with fewer. Also look into how powerful the device is, in general, so you know how high you can take the intensity.


Especially if you’ve never used a TENS unit before, you’re going to want to think about how easy your new product is to use, and how easy it is to learn. There are plenty of portable TENS machines which feature large screens that are also backlit and easy to see.

Directions are straightforward, and can be adjusted to your liking with just the push of a button. You want to look for buttons that are clearly labeled, so you don’t make a mistake, or just get frustrated with it and stop using it, because that’s not going to be of any help to you.


The devices reviewed above come with two options: AAA batteries, or a rechargeable lithium battery. The preference will depend on you, but most times, people prefer the built-in lithium rechargeable batteries. The reasons are pretty clear.

They’re not only convenient, as you don’t have to worry about them running out of charge all of a sudden, and you don’t have to spend extra money on buying replacement batteries all the time. However, you’ll also want to think about how they’re recharged.

Many can be recharged through a USB cord/port, which is probably the most convenient, as pretty much everyone has a USB cord or port handy on their laptop, at home, or in the car.

Size/Ease of Transportation

While TENS machines aren’t generally large, by any means, they do vary in size. For most people, they want a good balance between portability and ease of use. If you select the smallest-sized machine, you may be happy with how easy it is to take with you, but the screen isn’t going to be as easy to read.

With that being said, one that’s the size of a smartphone is generally a good idea. It’s natural to use, as most of us have a smartphone in our hand a good amount of the time anyway. In addition, the screen size is large enough to see easily, while still being portable, and ideally, lightweight. You probably don’t want to be carrying a brick around.

FAQs – Frequently Asked Questions

We have also answered the most frequently asked questions in regards to the best TENS machines out there, to help you be more confident in the product you select.


Q: Are TENS and EMS the same?

They are not! They are often used together, and compared with one another, but they do differ. TENS stimulates the nerves, and is meant to reduce both chronic and acute pain, making it great for just about anybody. EMS makes the muscles contract, making the machine perfect for recovering, training, rehab, prevention, as well as even enhancing appearances, cosmetically.


Q: How many channels and pads do I require?

That’s solely up to you, but the most common option is a dual channel unit, as mentioned above, as you can use either 2 or 4 pads simultaneously. Each channel has two pads, and both are need for TENS to work properly, as a charge is sent through one positively, and another, negatively.

With a  dual channel unit, you can also treat two parts of the body at once, which means more effective and quicker treatment.


Q: What is the difference between “channels” and “modes”?

To be honest, there’s really not a difference. It all depends on whichever term the manufacturer prefers to use.


Q: What are fully-isolated channels?

They are what allow you to operate separate programs on different channels, rather than just controlling the intensity for that channel.


Q: What can TENS devices treat?

They can be used for a wide variety of chronic and acute pain, including but not limited to: arthritis, fibromyalgia, foot pain, labor pain, hip pain, knee pain, back pain, neck pain, shoulder pain, sciatica, neuropathic pain, sports injuries, and much more.


Q: Do I require a prescription for a TENS unit?

Nope! They’re available OTC in a number of countries, including the US, Canada, and more. However, we do recommend using the machine only if your doctor or another health professional recommends it.

Buyers Tips

#1: Make sure your skin is both clean and dry before using. Not only that, but make sure your skin is free from any oils or lotion.

#2: If your skin is sensitive, try to use an electrode pad that is made with “skin-friendly blue gel”.

#3: You can change the flow of the electrical feeling if you move the pads further or closer together, or by changing the direction of the pads. Place them either vertically, horizontally, or diagonally.

#4: Make sure the knobs are all the way turned off on your device when you’re finished, and take out the battery (if you can) if you’re not going to use it for a month or more. Always make sure your unit is turned off before moving the patches to avoid a harsh sensation when taking them off.

#5: Stay hydrated before, during, and after your treatment. As TENS makes your body release endorphins, staying hydrated will help you keep good amounts of helpful chemicals in your body.

In March 2019 Amazon announced that Health Savings Accounts and Flexible Spending Accounts (HSA/FSA) would be accepted as new forms of payment for eligible product purchases. Using HSA/FSA funds to purchase on Amazon can be a great way to reduce taxes and reduce overall healthcare costs for items not covered under medical insurance. Users of such medical savings plans are issued a debit card by their provider, which can be added to their payment methods in their Amazon account.

Whether items sold on Amazon are deemed as eligible for HSA/FSA plans remains the responsibility of the buyer and their particular health plan provider. It’s ultimately up to the IRS and participating health plan providers to deem which medical and health products are considered eligible for the payment plans.

But the eligibility is quite broad and inclusive of thousands of products that are sold on Amazon and considered Health Savings and Flexible Spending Accounts plan-eligible.
