Frequently Asked Questions
Are portable TENS units safe to use for back pain?
When used according to the manufacturer’s instructions, TENS units are generally safe for temporary relief of muscle and joint pain. Avoid placing pads over the heart, throat, or broken skin, and consult your doctor if you have a pacemaker, epilepsy, or are pregnant.
How long do the electrode pads last while traveling?
Pad lifespan varies with care, skin oils, and storage. Many included pads are rated for dozens of uses (some models quote ~45–50 uses). To extend life, clean skin before application, store pads on their backing in a sealed bag or the included pouch, and use the pad holder if provided.
Can I use a TENS unit on a flight or in public places?
Yes — TENS units are small, battery-powered, and typically allowed in carry-on luggage. Be discreet: low-intensity settings are best in public. Always follow airline rules and be considerate of nearby passengers if using in a shared space.
