What is a TENS machine and how does it work?
A Transcutaneous Electrical Nerve Stimulation (TENS) machine delivers low-voltage electrical pulses through adhesive electrode pads placed on the skin. These pulses help modulate pain perception by stimulating nerves and promoting muscle relaxation. TENS provides drug-free, non-invasive relief for common musculoskeletal discomfort. Always follow the included user manual and consult a healthcare professional for medical advice.

Are TENS machines safe? Any side effects or contraindications?
TENS is considered safe for most people when used according to instructions. Do NOT use TENS if you have a pacemaker, implanted defibrillator, or certain cardiac conditions without medical approval. Avoid placing electrodes over open wounds, the front of the neck, or the eyes. Mild skin irritation at electrode sites can occur; stop use and consult a clinician if irritation persists. This FAQ provides general information — consult your healthcare provider for personalised medical advice.
How do I apply and maintain electrode pads?
Clean and dry the skin area before placing pads. Press firmly to ensure full contact. After use, store pads on the protective plastic sheet and keep them in a cool, clean place. Pads eventually lose adhesiveness — replace when they no longer stick reliably. Replacement pads are available through our shop.
How long do battery and pads last?
Battery life varies by model and usage; rechargeable units typically provide multiple sessions per charge. Electrode pad lifespan depends on care and frequency of use; with gentle cleaning and proper storage, pads can last many sessions. Consult the specific product page for manufacturer estimates.
Can I use a TENS machine after surgery or for chronic conditions?
TENS is used by some people for post-operative pain and chronic pain management, but you must consult your surgeon or treating clinician before using a TENS device after surgery or for ongoing medical conditions. Your clinician will advise whether TENS is appropriate and how to integrate it with other care.
How many channels and modes do your devices have?
Many of our units feature dual-channel outputs (treat two areas simultaneously) and multiple preset modes for different sensations and goals (e.g., massage, kneading, acupuncture-like pulses). Exact channel and mode counts are listed on each product page.
Are your devices travel-friendly, cordless, and Type-C rechargeable?
Yes — several models are compact, lightweight, and designed for travel. Many include **USB-C / Type-C charging support**, allowing modern, convenient recharging with a universal cable. Check specific product details on the shop pages.
Do your TENS machines support USB-C / Type-C charging?
Yes — our latest models include **USB-C (Type-C) charging**, making recharging easier with standard cables and fast chargers. Refer to each product’s specifications for exact charging info.
