Nitecore® NU20 is a USB rechargeable headlamp with four brightness levels up to a bold 360 lumens plus two rescue modes and a runtime of up to 100 hours. It’s compact and lightweight at just 1.16 oz (32.9 g) with our exclusive UL headband, perfect for backpacking. Never worry about running out of juice or replacing batteries, just plug into a power bank battery to recharge.

NU20 has a micro-textured reflector providing 100˚ wide-angle flood illumination for outstanding night vision. The light tilts down up to 52˚ for reading or close-up work. And a switch guard prevents the light from accidentally turning on in your pack or pocket. The wide elastic headband is comfortable and highly adjustable to fit your head, hat, or helmet. Our optional UL headband reduces weight with full adjustability and functionality.

A single button operates all functions for convenient one-handed control. The interface is quite simple. For low light, press once, wait 3 sec, then press again to turn off. For medium light, press twice, wait 3 sec, then press once to turn off. For high brightness, press three times, wait 3 sec, then press again to turn off. Alternatively, you can cycle from low>medium>high by pressing the switch repeatedly within 3 sec. To enter turbo mode, with the light turned on in any mode, hold the switch down for 1 sec, and press once to turn off.

You can also access two rescue modes, SOS and location beacon. SOS repeatedly flashes SOS in Morse code (. . . ––– . . .), while location beacon repeatedly flashes a single short flash. With the light turned off, press and hold the switch for 3 sec to enter SOS mode. Pressing the switch within 3 sec again will change to beacon mode. Press once to turn off.  

NU20 has a built-in, long-lasting 600 mAh Li-ion rechargeable battery that holds power equal to three AAA batteries yet is much more sustainable. An intelligent protective charging circuit and a Micro USB connection make it easy to recharge. Since you probably already carry a spare battery to charge your phone, there’s no need to worry about running out of power or replacing batteries, just plug into a power bank, wall charger, computer, or car (USB cable provided). The light maintains full functionality while charging.

To see how much battery power is left, with the light turned off, hold down the switch for 1 sec and release. The switch will flash 3 times if you have more than 50% power, 2 times if you’re below 50%, and 1 time if you’re below 10%. Plug it in and an indicator light lets you know when the charge is complete. It takes approximately 2 hours to fully charge the battery. A rubber cover protects the USB port from dirt and moisture.
