Quiet, Discreet Relief You Can Use at Work
Wired TENS units come with loose cables and a handheld controller.
Not exactly easy to hide under clothing, and definitely not something you want noticed at work.
Wellue’s cordless pods change that. The pods sit comfortably under your shirt, so you can get relief at your desk without anyone knowing.
Just quiet, relaxing therapy that feels more like a gentle massage.
Pain Relief Wherever You Go
Each TENS pod fits comfortably in the palm of your hand and slips easily into your pocket, purse, or gym bag.
Palm-size design
1.77" × 1.77" × 0.31" (4.5 × 4.5 × 0.8 cm)
ULTRA-LIGHT
26g each
Treat Up to 4 Areas at Once
Most home TENS units make you choose one spot at a time.
This one lets you treat up to four, when your upper back, lower back, and knees all demand attention.
Just 15 minutes can help relax tight, sore muscles.
Each pad has its own channel, so you can set the mode and intensity for each area.
Back Pain
Leg Pain
Ankle Pain
Different Pain, Different Modes
9 therapeutic modes: from classic continuous and burst modes to modulation and massage-like rhythms, you can set the exact sensation that feels best to you.
16 intensity levels: on a good day when pain is mild, maybe a gentle buzz at level 3 is enough to take the edge off. On a bad day, you might crave a higher setting to really knock down the pain. With a wide range of intensities, this device covers it all. It’s like having both a soft massage and a deep massage machine in one. Just choose what your body needs at the moment.
Relief for Long Workdays
Neck, shoulders, and back tension from long workdays.
Chronic Joint Pain
Designed for mild arthritis discomfort or lower back stiffness.
Post-Workout Soreness
Help ease muscle soreness in quads, calves, and glutes.

( 1 ) Do not apply the electrodes on the swollen, infected or inflamed areas or skin eruptions.
( 2 ) Do not apply the electrodes on inappropriate sites, such as over chest, the head, anterior neck, eyes, mouth and the front of throat.
( 3 ) Do not apply the electrodes on areas of broken or damaged skin, such as open wounds.
( 4 ) Do not apply the electrodes on the skin with diminished sensation because nerve damage is likely to diminish the effectiveness and the patient maybe unaware that high-intensity currents are causing skin irritation.
( 5 ) Stimulation should not be applied across or through the head, directly on the eyes, covering the mouth, on the front of the neck, (especially the carotid sinus), or from electrodes placed on the chest and the upper back or crossing over the heart.
( 6 ) Stimulation should not be applied transthoracically in that the introduction of electrical current into the heart may cause cardiac arrhythmias.
( 7 ) Stimulation should not be applied over the carotid sinus nerves, particularly in patients with a known sensitivity to the cartid sinus reflex.
( 8 ) Never use the device while sleeping.
( 9 ) Contraindications: Patients with pacemakers and cardiovascular problems should not use the device. The device should not be administered over the abdomen or pelvis during pregnancy. Patients with epilepsy should not apply the electrodes to the neck or head. Patients with heart disease, cancer or any other health conditions should not use the device, unless recommended by a medical practitioner. Patients who have suffered acute trauma or surgical procedures in the past six months. Patients with undiagnosed pain syndromes should not use the device, unless recommended by a medical practitioner.

My arms were so tense from typing all morning, so I slapped one of these little things on during lunch. Lowkey feels like someone’s massaging me while I answer emails. 😂 Also got two more going on my shoulders. Feels weirdly relaxing. Didn’t expect it to actually help this much?? It's some medical-grade TENS thing apparently. Just glad it’s not buzzing my muscles off lol
C
I honestly like it a lot. As soon as I stick it on, I feel a nice, comfortable tingling. It never feels pain!!
What impressed me the most is how good the pads are. They stick really well to the skin. I’ve worn them for about three hours at a time, and when I take them off, my skin is totally fine. No redness and no irritation. I even accidentally stuck one pad onto a tissue. I rinsed it with water, let it dry, and it looked clean again. The stickiness was still strong after that. That really surprised me.
These pads feel well made and definitely not cheap. You can tell they are good quality and built to last.
B
This might sound like a small thing, but I seriously appreciate the way they designed the power button on this TENS device. It’s slightly recessed, so when I’m lying down or leaning against a table, it doesn’t get accidentally pressed. No more surprise shut-offs just because I shifted my leg or leaned the wrong way.
That’s not just wireless freedom, that’s real freedom. Like… you put it on, and forget it’s even there. Just sit back, relax, and let it do its thing. Honestly, little things like this show me they really thought about how people actually use the device day to day.
R
It is a great product and it works very well and it’s very easy to do…👍
E
I’ve use tens units for years but was tired of the wires. I love this wireless device, it gives me freedom and works perfectly.
D
I live with chronic pain, and as an older adult, the wellue cable-free tens has really made my life easier. Since it’s completely wireless, I don’t have to mess with any cables, I just place the pods and use the small remote. It helps me manage my pain at home and move around comfortably, without always relying on medication. It honestly takes a big burden off my daily life.
P
The best money I ever spent. It helps with my low back pain, pelvic floor pain, and even my fibromyalgia flares. I can’t say enough about this except THANK YOU!!!!!! It is something that allows me to get up in the morning and walk, not shuffle to my coffee pot!
S
I strained my lower back after lifting some heavy boxes. I set the device to the mild setting since I wasn’t sure how it would feel, but it was surprisingly relaxing. It felt like a light chair massage—not too intense, just right. The pain eased up quickly, and I was able to get back to doing chores like sweeping and mopping without any discomfort. I really appreciate that I can wear it whenever I need quick relief. Thank Wellue!!!!
J
Great product for deep message or light message. Has many different settings. Helps my lower back and neck pain. Easy to use and it's rechargeable.
E
Really helps with muscle pain

I’ve use tens units for years but was tired of the wires. I love this wireless device, it gives me freedom and works perfectly.

I live with chronic pain, and as an older adult, the wellue cable-free tens has really made my life easier. Since it’s completely wireless, I don’t have to mess with any cables, I just place the pods and use the small remote. It helps me manage my pain at home and move around comfortably, without always relying on medication. It honestly takes a big burden off my daily life.

The best money I ever spent. It helps with my low back pain, pelvic floor pain, and even my fibromyalgia flares. I can’t say enough about this except THANK YOU!!!!!! It is something that allows me to get up in the morning and walk, not shuffle to my coffee pot!

I strained my lower back after lifting some heavy boxes. I set the device to the mild setting since I wasn’t sure how it would feel, but it was surprisingly relaxing. It felt like a light chair massage—not too intense, just right. The pain eased up quickly, and I was able to get back to doing chores like sweeping and mopping without any discomfort. I really appreciate that I can wear it whenever I need quick relief. Thank Wellue!!!!
