What is the difference between this TENS unit and a vibrating massager? Which one is better for chronic muscle pain?

Vibrating massagers only relax surface tissues. This TENS EMS device uses electronic pulses to block pain signals at the nerve (TENS) and stimulate deep muscle recovery (EMS). It’s a professional health aid for chronic pain relief.

How many uses do the TENS pads last, and what are the 3 sizes for back, shoulder, and neck pain relief?

Pads last 50+ uses. Sizes: Small (40x40mm/1.6″x1.6″) for neck; Medium (40x60mm/1.6″x2.4″) for shoulders; Large (40x90mm/1.6″x3.5″) for lower back. Tip: Wipe gel with a damp finger to restore stickiness. Keep water away from wires and back side.

Is there a way to prevent accidental intensity spikes during a session? I’m worried about sudden “shocks.”

Yes! To prevent accidental intensity changes, simply long-press the timer button to activate the screen lock once your level is set. This ensures a safe, consistent pulse delivery, making it a reliable health aid for sensitive users.

Does this TENS unit allow independent intensity control for dual channels? Can two people use it simultaneously?

Yes! While modes are synchronized for a balanced and safe therapy experience, each channel features 20 independent intensity levels. This allows two people to share the device and customize their own power level based on sensitivity.

What type of charger does this use? Can I charge it with a standard phone wall adapter or a power bank?

Our unit uses a modern Type-C port for fast, universal charging. You can safely recharge via wall outlets, power banks, or laptops. The high-capacity battery ensures multiple sessions per charge, perfect for home, office, and travel.
