It delivers adjustable frequency pulses (1–100 Hz) via self-adhesive electrode pads or alligator clip wires to promote muscle stimulation, nerve activation, and deep relaxation.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use the SDZ-IIB without acupuncture needles?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The unit comes with self-adhesive electrode pads (50 mm × 50 mm) that can be applied directly to the skin for TENS-style stimulation without needles. The alligator clip wires are included for traditional electroacupuncture needle use.\u003c\/p\u003e\n\u003ch4\u003eQ: Does the SDZ-IIB work with both 110V and 220V power systems?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The included power adapter is compatible with AC 110V (60 Hz) and AC 220V (50 Hz) electrical systems and comes with US, EU, UK, and AU plug options. It can also operate on a standard DC 9V battery (not included).\u003c\/p\u003e\n\u003ch4\u003eQ: How many channels does the SDZ-IIB have, and can they be controlled independently?\u003c\/h4\u003e\n\u003cp\u003eA: The SDZ-IIB features 2 independent output channels, each with its own intensity control. This lets you stimulate two different body areas at the same time with different settings for each channel.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
