It has no battery: plug the USB cable into a wall adapter, laptop or power bank and it runs straight away, which keeps it light and means it never needs charging. The Velcro wrap fits an upper arm, forearm, elbow or calf. At $179 it suits someone who wants a simple, no-battery wrap for a small muscle group and already owns a power bank for cordless use.\u003c\/p\u003e\u003ch2\u003eKey specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eLEDs\u003c\/td\u003e\n\u003ctd\u003e50: 40 x 660 nm red + 10 x 850 nm near-infrared\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWavelengths\u003c\/td\u003e\n\u003ctd\u003e660 nm red + 850 nm near-infrared\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated power\u003c\/td\u003e\n\u003ctd\u003e10 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower\u003c\/td\u003e\n\u003ctd\u003eDC 5 V over USB; 5 V \/ 2 A source recommended; no internal battery\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize\u003c\/td\u003e\n\u003ctd\u003e32 x 18 cm (12.7 x 7.1 in.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSession\u003c\/td\u003e\n\u003ctd\u003e15–20 minutes suggested, 30 minutes maximum, per Nicebeam\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eControls\u003c\/td\u003e\n\u003ctd\u003eNicebeam's description lists a digital control and timer; its spec sheet does not give a timer range\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eFlexible fabric and neoprene, Velcro closure\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater resistance\u003c\/td\u003e\n\u003ctd\u003eNot waterproof\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIrradiance\u003c\/td\u003e\n\u003ctd\u003eNot published\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eNot published\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRegulatory\u003c\/td\u003e\n\u003ctd\u003e'FDA Registered, CE Certified', per Nicebeam\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e1-year limited\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRed light armband\u003c\/li\u003e\n\u003cli\u003eUSB power cable\u003c\/li\u003e\n\u003cli\u003eUser manual\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGood to know\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower source:\u003c\/strong\u003e any 5 V USB port works, but Nicebeam recommends 2 A for full brightness.
