Featuring 4 independent channels and up to 8 electrode pads, it targets multiple muscle groups simultaneously. Its rechargeable battery lasts up to 7 days, complemented by an intuitive LCD interface with memory function. Approved for FSA and HSA spending, this device offers versatile, on-the-go therapy for back pain, arthritis, sports injuries, and more. ## Description ✔ Effective Pain Relief: Our TENS unit uses Transcutaneous Electrical Nerve Stimulation (TENS) technology to provide effective pain relief by delivering tiny electrical impulses to your nerves. This stimulation helps your body produce endorphins, its natural painkillers, to alleviate muscle pain from activities like exercise or daily tasks.✔ Versatile Use: The TENS unit features multiple modes to address various treatment needs, whether you're at home, in the office, or on the go. Choose from massage, tapping, or acupuncture modes to match your preferences and pain types. With one-touch mode selection, it's easy to use without complex operations.✔ Energy-Saving: Equipped with a long-lasting battery, the unit minimizes the need for replacements and reduces environmental impact. It automatically shuts down within 3 minutes of use to conserve energy and can last up to a week on a single charge.✔ Tips: If the adhesive pads become dirty or lose stickiness, gently rinse them under cold water. If you have any issues with the TENS unit, our team is ready to assist you. Your safety and satisfaction are our top priorities. Review: Works Great, Wish there was a constant setting - This is a great unit and it's very easy to use, it comes with three different sizes of pads, and you get two pairs of the medium pads, a pair of large pads and a pair of small pads. I have used the medium ones several times now and I have yet had to wash them, because the adhesive is still really strong. I would suggest using it on clean dry skin, (no lotion, etc.) and the pads should last a while before you have to clean them, I usually have a session with this after I get out of the shower. The only downside that I have against this unit is that there is no setting for a constant current. They are all pulsating, some longer pulses than others. I find it rather strange and I don't know if it works as well as the other unit I used to have a long time ago. It had one mode it was on or off and you could control the power level of the current. This one seems pretty strong as far as currents go, I have been using it on the medium setting, anything above that gets painful. So if you like to use the high settings on the units this will work for you for sure. The pulsating will take some time to get used to, I find that the cupping one is more closely to the old steady current unit I had. Don't get me wrong this is a great unit, and for the price it's well worth it, but if you're looking for one that has a steady current like the older models did, this one doesn't offer that. Review: Works great and does effevtively relieve muscle pain after using it - My husband was a little skeptical to use it at the beginning. But after he tried it, he wants to use it now. ## Features - 𝑭𝑺𝑨 𝑬𝒍𝒊𝒈𝒊𝒃𝒍𝒆 𝑰𝒕𝒆𝒎𝒔 & 𝑯𝑺𝑨 𝑺𝒕𝒐𝒓𝒆 𝑨𝒑𝒑𝒓𝒐𝒗𝒆𝒅: Eligible for flexible spending and health savings accounts - 𝑫𝒓𝒖𝒈-𝑭𝒓𝒆𝒆 𝑷𝒂𝒊𝒏 𝑹𝒆𝒍𝒊𝒆𝒇: The Etekcity Clinical Strength TENS Muscle Stimulator offers effective management of pain and muscle soreness from conditions such as back pain, arthritis, joint pain, and sports injuries without medication - 𝑩𝒓𝒐𝒂𝒅𝒆𝒓 𝑪𝒐𝒗𝒆𝒓𝒂𝒈𝒆: With 4 independent channels (A/B), this device supports up to 8 electrode pads, allowing you to target multiple areas simultaneously for more effective and efficient treatment - 𝑼𝒔𝒆𝒓-𝑭𝒓𝒊𝒆𝒏𝒅𝒍𝒚 𝑶𝒑𝒆𝒓𝒂𝒕𝒊𝒐𝒏: Featuring intuitive function buttons, a large bright LCD screen, and a memory function, the device is designed for easy and quick setup - 𝑹𝒆𝒄𝒉𝒂𝒓𝒈𝒆𝒂𝒃𝒍𝒆 & 𝑷𝒐𝒓𝒕𝒂𝒃𝒍𝒆: Its compact design charges through a wall charger, power bank, or laptop USB, and the battery lasts up to 7 days on a single charge, making it perfect for both travel and everyday use - If you experience any issues during use, please contact the Etekcity customer service team. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #36,391 in Health & Household ( See Top 100 in Health & Household ) #65 in Muscle Stimulators & Accessories | | Customer Reviews | 4.6 out of 5 stars 6,888 Reviews | ## Product Details - **Brand:** Etekcity - **Color:** White - **Style:** Tens - **Item Weight:** 3.4 Ounces - **UPC:** 817915026731 ## Images ![Etekcity 4-Channel Rechargeable TENS Unit, Muscle Stimulator, FSA - Image 1](https://m.media-amazon.com/images/I/71Z0cfv56qL.jpg) ![Etekcity 4-Channel Rechargeable TENS Unit, Muscle Stimulator, FSA - Image 2](https://m.media-amazon.com/images/I/81ikRxJFuuL.jpg) ![Etekcity 4-Channel Rechargeable TENS Unit, Muscle Stimulator, FSA - Image 3](https://m.media-amazon.com/images/I/91Olj7mMPzL.jpg) ![Etekcity 4-Channel Rechargeable TENS Unit, Muscle Stimulator, FSA - Image 4](https://m.media-amazon.com/images/I/81w0Nme-MPL.jpg) ![Etekcity 4-Channel Rechargeable TENS Unit, Muscle Stimulator, FSA - Image 5](https://m.media-amazon.com/images/I/81UBDrAUDcL.jpg) ## Questions & Answers **Q: Do I need to use gel???** A: No gel, just use a little water to wash the pads & they are reusable. **Q: Can you run different programs on each channel?

And, what are the intensity levels in milliamps?** A: I've had a cheaper TENS unit for 10yrs, used it lots, and the built-in battery is just now starting to go bad. Only had to buy 1 package of replacement pads in 10 yrs. **Q: Pad attached to the cord. Does the cord attach to the main unit? If so isn’t this awkward to wear. Please helpaa** A: Please know that the cord needs to be plugged in the main unit and place electrode pads on skin. We recommend using this unit at home or anywhere you could relax yourself to avoid awkwardness. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Great, Wish there was a constant setting *by R***K on June 24, 2024* This is a great unit and it's very easy to use, it comes with three different sizes of pads, and you get two pairs of the medium pads, a pair of large pads and a pair of small pads.

But after he tried it, he wants to use it now. ### ⭐⭐⭐⭐⭐ Just buy it! *by J***R on April 21, 2026* For 3 years I've forgotten to review this little amazing unit. If it broke right now as I'm typing this I'd re order it. The battery life is fantastic and while I primarily use it on my lower back I'm sure it works equally as well on other muscle groups. I feel like its an absolute gem for the price! ## Frequently Bought Together - Etekcity FSA HSA Store Eligible 4-Output TENS Unit, Muscle Stimulator Machine for Pain Relief Physical Therapy, Back, Nerve, Sciatica, Neck, Shoulder,Period Cramp Relaxer,Rechargeable Electric Device - Etekcity Smart Scale for Body Weight FSA HSA Store Eligible, Bathroom Digital Weighing Scale with BMI, Body Fat, Muscle Mass, Accurate Bluetooth Home User Health Equipment Sync Apps - CURAD Assorted Bandages Variety Pack, 300 Count, 6 Styles Including Antibacterial, Waterproof, Sheer, Plastic, Heavy Duty & Flex-Fabric, Protects Scrapes, Cuts & Burns, Latex-Free --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/162581699-etekcity-4-channel-rechargeable-tens-unit-muscle-stimulator-fsa](https://www.desertcart.us/products/162581699-etekcity-4-channel-rechargeable-tens-unit-muscle-stimulator-fsa) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-08*
