A Drug-Free Way to Relieve Your Pain: The AVCOO 3-in-1 TENS machine combines three powerful therapies—TENS, EMS, and MASSAGE—into one compact device. TENS modes use mild electrical pulses to stimulate sensory nerves, helping block pain signals for pain relief in the back, shoulders, neck, waist, arms, and legs. Its EMS modes target motor nerves to improve muscle performance, while massage modes provide gentle, massage-like pulses to ease tension
24 Modes and 30 Levels: Featuring 24 modes and 30 intensity levels, this TENS unit for pain relief offers personalized therapy. The independent intensity level control for dual channels allows you to customize treatment for multiple body areas simultaneously, effectively relieving pain in the elbows, shoulders, back, waist, and legs
Innovative Designs Upgrade Your Relief Experience: Upgraded with a 3.3″ color display and an intuitive interface, this muscle relaxer makes operation clearer than ever. Additionally, featuring a U.S.-patented single Type-C port, this TENS machine uses a 4-in-1 cable to eliminate wire tangles. This streamlined design is ideal for portable use. The high-quality Type-C port also reduces the risk of failure from loose connections or poor contact, ensuring a stable and consistent therapy experience
Powerful Battery for Up to 50 Hours of Use: Equipped with a rechargeable 400mAh battery, this EMS muscle stimulator lasts up to 50 hours, and the continuous mode provides uninterrupted relief. Plus, this TENS unit supports multiple charging options, including wall chargers, power banks, and laptops. A full charge takes only 2 hours, letting you enjoy treatment anytime
Premium Multi-Shaped Pads: The AVCOO TENS pads come in three shapes to suit different treatment areas: palm-shaped pads for the back, arms, waist, and thighs; rectangular pads for large areas like the waist and thighs; and oval pads for smaller areas like the wrist and the web of the thumb. All pads are made from latex-free gel that has strong adhesion for up to 50 uses. They are skin-friendly, easy to peel off, and leave no gel residue, ensuring a comfortable therapy experience every time
Complete Kit: This package contains the following: 1 x AVCOO Stim Machine, 2 pcs 2″ x 4″ Rectangular Pads, 6 pcs 2″ x 3″ Palm-shaped Pads, 2 pcs 1″ x 2″ Oval Pads, 1 x Lead Wires, 1 x Type-C Charging Cable, 1 x Storage Bag, 1 x Pads Holder, 1 x User Manual, Premium Customer Service and 24-Month Lifetime Technique Support

Flexibility and Duration
Saved my back. I have a surgically implanted spinal cord stimulator (SCS) for back pain, when the battery died I had to wait almost 6 months to get it replaced. I found this on Amazon and tried it. It made it possible for me to get through most of my day without taking narcotics for the pain. Because it’s meant for short term relief it will never replace my SCS unit, but it sure made the wait bearable. The options are wonderful and being able to use it 90 minute at a time (my old one was 15), gave it time to do the job.

Great TENS Unit
Great product, the battery life is very nice. I travel a lot and use it on long flights and it has never died on me mid-flight. It took me a week to get to level 5 out of 20, so don’t worry about it not being powerful enough!

Add this to the pain relief “toolbox”
Husband loves this device I got him for a gift. Easy to use, holds a charge so long we wonder how they do that. After four months haven’t had to swap out any sticky pads, not a big deal when he does have to. Helps his pain and that’s what I was after. Recommend.

Sweet relief!
This is by far my favorite TENS Unit. It comes with the biggest reusable patches; very high quality.I gave it four stars only because the use of the center button can be confusing. Up and down arrows are for the timer; left and right change the type of message, and the small center button locks the buttons.

GREAT battery life
I have had a hard time finding a tens unit that had a setting I was looking for. This tens unit is perfect and exactly what I was looking for. Easy to use. My only complaint is that the two cords are connected and most times I only use one set of pads, so the other two cords are just hanging. It arrived fully charged and I have used it several times and days without using it and it still has a full charge.

Lower back and knee pain
Love it, really does provide pain relief. I’ve been using it consistently for my lower back and knees. The battery lasts quite a bit.

So many options
So many options on this little gadget. I have had a few TENS units over the years and none have come even close to the options or build quality of this. Not as straight forward to use as some of the others I have had but also way more options.
