Editor’s Recommendation : 5 Tens Unit

Top 9 Best Tens Unit Reviews

As the working mechanism of TENS units is related to body pain, finding one that properly does its job may seem tough. Here are the ones we found to be the best at what they do.

1. Belifu Dual Channel TENS EMS Unit Review

The first product that we’d like to draw your attention to is this one from Belifu. It’s a dual-channel unit that allows you to set the intensity at 20 different levels. We consider this to be the best portable tens unit in the market today due to its travel-friendly size and easy-to-use features.

You can use this for arthritic or inflamed joints, back pain, shoulder pain, and even stiff muscles or cramps. It comes with 10 pieces of self-adhesive conductive pads, which are reusable.

If you plug in two wires at the same time, then the best way to use the device is to connect 4 or 6 pads and place them on your skin at the same time. And as for plugging in one wire, you can easily use two pads on your skin without worry.

Moreover, the maximum run-time for the device is 60 minutes. The timer can even be set as low as ten minutes. Moreover, as this unit runs on rechargeable lithium batteries, you can connect it to any power bank or laptop to recharge. So, it’s perfect for using anywhere.


  • Travel-friendly size and portable unit
  • Comes with built-in rechargeable batteries
  • Has 24 different modes and 20 intensity levels for varied use
  • Easy to use


  • Pads don’t always stick well

2. TENS 7000 2nd Edition Digital TENS Unit Review

If you’re looking for something more professionally approved, then you can opt for this unit from TENS 7000. In our opinion, this is the best medical grade tens unit you’ll find. The product has been a fan favorite since 2008 so you can rely on it to be top-tier in quality.

With this, you can easily adjust the intensity from 0 to 100 mA with 10 mA increments in each turn. For targeted areas, they’ve designed this to be a dual-channel unit having four pads.

It can be used for stimulating muscles and nerves as well as relieving pain caused by tennis elbow or bursitis. There are also five treatment modes-burst, normal, modulation, strength-duration 1, and 2.

What we loved the most about this unit is how powerful it is. You can use it for lesser time than other units to get faster and better results. Most users don’t even need to turn it up to 15 minutes at all for pain relief. This is as close as you can get to having medical-grade equipment without a license.


  • Pads are of premium quality
  • Powerful unit
  • Intensity level can be controlled easily from 0 to 100 mA
  • There are five different treatment modes


  • Comes in a big carry case which isn’t as travel-friendly as smaller units

3. HealthmateForever YK15AB TENS Unit Review

For at home Tens therapy, another great package you can invest in is this one by the brand HealthmateForever. Just as reassuring as the brand name, the product itself is very competent to work for different types of conditions.

For users who are new to this treatment, it has intuitive buttons with clear labels like “Neck”, “Knee,” and “Shoulder,”, etc. to make things easier.

With this kit, you’ll be getting 15 modes to select from. The package provides 4 sets of dual wires, 8 pieces of pads, a holder to keep them, and 3 AAA batteries. Moreover, it comes with a user manual and an application chart for proper utility.

Our favorite part about this kit was the belt clip. As trivial of detail as it may seem, it’s still something that works as a pet peeve for many users. The belt clip allows more mobility and allows anyone to carry it while in use.

You’ll have to maintain some caution while using this if you’ve recently undergone any medical procedure or have abnormal blood pressure.


  • Belt clip for attachment and extra mobility
  • Variety of modes with clear area-specific labels present
  • Comes at a great price
  • Timer allows 80 minutes of maximum use


  • Can only set it to one region of the body even when using different channels

4. NueMedics Tens Unit Machine Pulse Massager Review

Tens Unit Machine Pulse Massager 24 Massage Modes Rechargeable Muscle Stimulator Device with 10 Pads

Coming to our fourth pick, let’s talk about one of the best tens units for back pain. This is one of the most user-friendly devices we found while testing. It has a large, backlit LCD, which is very clear and easy to see. There are 24 different massage modes that you can use according to your needs.

The fact which made this kit stand out was its super simple labels. There are varied modes labeled for Neck, Shoulder, Back, and Elbow, etc. Moreover, the intensity of stimulation type is labeled as “Knead”, “Tap”, “Acu” (for acupuncture pressure), and “Random”.

So, you’ll know what you’re getting yourself into when you press the button.

It’s perfect to relieve back pain as the ten pads provided in the package are quite large. They’re also reusable, so you can have them for a while before needing new ones. The company also provides a snap-together casing for added protection of the device in case someone drops it.


  • Very user-friendly and simple

  • Long-lasting battery life
  • Portable


  • Speed isn’t adjustable

5. AUVON Dual Channel TENS Unit Review

This is a small tens unit from AUVON, and it’s the perfect piece of equipment if you’re looking for versatility. As far as the usual units go, they seldom allow using the wired pads at different regions of the body at different modes.

But this one sure does. With this, you can easily set different modes via two separate channels at two regions of the body.

For the ultimate relaxing experience, this kit comes in a very portable and pocket-friendly pouch. You’ll get four square pads, four larger rectangular ones, and a USB cable with a charger in this kit. The manual, pad holder and wires are also included.

There’s a lock/ unlock feature for the LCD which is very handy. People who need to massage two different areas at the same time will enjoy this kit immensely.

7. Easy@Home Professional Grade Rechargeable TENS Unit Review

Our choice of the best overall tens unit is this next kit from Easy@Home. It’s a portable unit that you can carry with you outside your home. What’s more, is that this is a professional-grade device approved by the FDA and OTC. So, you can count on it to be very effective.

This comes with 20 different intensity levels starting from very mild and going all the way up to very powerful. It’s been designed to be massager for athletes and mimic the motions of actual human hands.

Since this has 5 different automated massage options, it’s very good for warming up before an exercise routine or any strenuous physical activity. There is a nice LCD screen which is easily readable and is backlit.

You’ll be able to use this as long as 120 minutes per session multiple times in one day as needed. And just like your phone or any other smart device, you can recharge it using a USB or DC connection. The frequency on this can be adjusted from 10 to 100 Hz so it’s very user-friendly.

8. AUVON Rechargeable TENS Unit Muscle Stimulator Review

The best value tens unit which we can recommend in a heartbeat is yet another product from AUVON. This muscle stimulator device has 16 pre-programmed modes, which are under 6 different massage categories.

Unlike conventional tens kits, you won’t have to set the time duration or frequency manually yourself. It’s all already set up, ready to be used.

In this kit, the electrodes (pads) are connected via pin connections. This is a much more professional-grade connection and thus provides a better and consistent flow of current compared to button connectors. You’ll get 8 regular pads, (2” x 2”) and 8 larger pads (2” x 4”) for larger regions like back areas and the shoulders.

A complaint we come across most often for different units is that the pads don’t stick or lose their stickiness over time. However, due to the American Gel pads included in this unit, you won’t have to worry about them falling off at all.

This is a very convenient and affordable pocket-sized unit that can help relieve your pains at any time.

Things to Consider Before Buying Best Tens Unit

There are a few things you need to look out for before settling on a tens unit for good. We’ve made a list of them right here.

  • Portability

These units come in a variety of forms. The way you’ll be able to use them and how convenient it’ll actually be depending a lot on the portability of the kit. Some brands provide a plastic casing with the kit to carry the electrodes and wires easily. Other brands include a handy belt clip to attach to your clothing during use.

Electrodes and wires included in these kits don’t really weigh much. So, you can easily carry them in small pouches or have them arranged in your bag easily nonetheless.

  • Single or Dual Channel?

The best Tens unit on the market is the one with dual channels. Can you guess why? That’s right — it’s due to the option of using it on different body parts at the same time.

best tens unit

With dual channels, you get to use different intensities as needed in your shoulders and your back simultaneously. In case of severe muscle pain, you’ll also get to use many pads together in one place at varying modes.

  • Adjustable Intensity and Speed

The pace and intensity at which we like our massage are not always the same. Your body’s demands for pain relief vary with different physical activities and issues. So, it’s always a good idea to opt for kits that allow low to high-intensity adjustments. It’s even better if you can control the speed.

  • Battery

Most of these kits run on lithium batteries and can be recharged. In case of the ones that need battery replacement altogether, check how long the battery life is estimated to be. To avoid running out of power at odd times, consider a good rechargeable unit that can be connected to a power bank.

  • Duration and Power

How much power does the kit need to run for an hour or so? Many units can run for 20 or even 30 hours continuously but have very low EMS capability and little power of providing the impulses.

The strongest tens unit can go for a long time and provide a consistent, powerful electrical flow during the entire time. That’s what you should have your sights set on.
