The Nitecore NU43 is a new model from the NU series. The NU43 is powered by a built-in 18650 battery with a capacity of 3400 mAh. Improved charging electronics allow you to fully charge the battery via the USB-C charging port in just 2 hours. Furthermore, the Nitecore NU43 can be used while charging. For this purpose, there will soon be a matching accessory that can be attached to the headband. The case is made of metal and polycarbonate. This mixture results in the low weight - the NU43 is currently the lightest head lamp with 18650 battery. The 32 mm wide headband ensures a comfortable fit and optimal weight distribution. The built-in optical sensor reduces brightness suddenly as soon as it registers an obstacle in front of it. This prevents overheating due to unintentional switching on.
