The wrap has a built-in 5000mAh rechargeable battery and charges via USB-C. You can wear it anywhere — reading on the sofa, working at a desk, or relaxing outdoors — with no power cord. You can also plug it in mid-session if the battery is low; it keeps running.\u003c\/p\u003e\n\n\u003ch3\u003eHow long does the battery last per charge?\u003c\/h3\u003e\n\u003cp\u003eBattery life varies with brightness and vibration settings. Most users get multiple back-to-back sessions per full charge. A full charge over USB-C typically takes a couple of hours, similar to charging a modern smartphone.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's the difference between 660nm and 850nm?\u003c\/h3\u003e\n\u003cp\u003e660nm is visible red light — you'll see a soft, cozy red glow. 850nm is near-infrared — you won't see it because it's outside the visible spectrum, but you'll feel the deep, even warmth from the panel. Mode 3 runs both wavelengths at the same time for the full Katalyst experience.\u003c\/p\u003e\n\n\u003ch3\u003eCan I use it on bare skin or over clothing?\u003c\/h3\u003e\n\u003cp\u003eFor the most direct light contact, wear it against bare skin or over a thin layer. The wrap's neoprene inner surface is soft and skin-friendly. If you prefer, you can also wear it over a light shirt — the warmth and vibration still come through comfortably.\u003c\/p\u003e\n\n\u003ch3\u003eDoes it get hot? Is it safe?\u003c\/h3\u003e\n\u003cp\u003eThe neoprene contact surface warms up to about 50°C (122°F) — comparable to a warm towel or a heated car seat. It is designed as a comfort heat, not a lab-style thermal product. Surface temperature is regulated automatically. If a setting feels too warm at any point, step down a brightness level or take a short break.\u003c\/p\u003e\n\n\u003ch3\u003eIs the wrap noisy?\u003c\/h3\u003e\n\u003cp\u003eThe dual vibration motors deliver a smooth, steady hum — quiet enough to wear while reading, watching TV or listening to a podcast. There is no clicking, knocking or jarring motion.\u003c\/p\u003e\n\n\u003ch3\u003eWill it fit me?\u003c\/h3\u003e\n\u003cp\u003eThe 45 cm × 31 cm main pad is shaped to drape over both shoulders and upper chest. The included 90 cm extension strap lets the wrap fit chest sizes up to about 60 inches (152 cm). If you have a larger or smaller frame, the strap is fully adjustable.\u003c\/p\u003e\n\n\u003ch3\u003eHow often should I use it?\u003c\/h3\u003e\n\n\n\u003ch3\u003eHow do I clean the wrap?\u003c\/h3\u003e\n\u003cp\u003eWipe the inner neoprene with a soft dry cloth after each use. For occasional deeper cleaning, use a barely-damp cloth with mild soap, then air-dry flat. Do not submerge the wrap, soak it in water, or put it through a washing machine — it contains electronics.\u003c\/p\u003e\n\n\u003ch3\u003eIs shipping free in the US?\u003c\/h3\u003e\n\u003cp\u003eYes — free US shipping on orders over $50. Orders under $50 ship at a flat $4.99. We ship to all 50 US states and Washington, D.C. only. Most orders arrive in 10–20 business days with USPS tracking.\u003c\/p\u003e\n\n\u003ch3\u003eWhat if I'm not happy with it?\u003c\/h3\u003e\n\u003cp\u003eEvery Katalyst order includes a 30-day return window and a 1-year manufacturer warranty.
