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. ## 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 | |---------------|-------| | ASIN | B07RL1CCXW | | Batteries | 2 Lithium Polymer batteries required.

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.
