It is compatible with many popular electronic blood pressure monitors including HEM-741, HEM-7121, HEM-7130, HEM-712, HEM-7122, HEM-752, HEM-745C, HEM-7300, HEM-8102A, HEM-942C, HEM-780N3, and models M4-I, M5-I, M6W, I-C10, among others. Always verify your device's voltage, current, and plug size before use.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use this cable with a USB power bank?\u003c\/h4\u003e\n\u003cp\u003eA: While the cable is compatible with USB power banks, many power banks feature an automatic shut-off triggered by very low current draw (around 90mA). This may cause intermittent or lost power. For uninterrupted performance, we strongly recommend using a standard wall USB adapter instead of a power bank.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the cable's output voltage and polarity?\u003c\/h4\u003e\n\u003cp\u003eA: The cable outputs DC 6V at up to 1A, with center-positive polarity (inside positive, outside negative). It accepts a standard USB Type-A 5V input and steps it up to 6V for compatible devices.\u003c\/p\u003e\n\u003ch4\u003eQ: How long is the cable?\u003c\/h4\u003e\n\u003cp\u003eA: The cable measures approximately 100cm (about 39 inches), providing convenient reach for desktop or bedside use.
