Elegant • Ultra-compact Smallest size, big power: The K4R is a rechargeable key ring light with up to 120 lumens of light output. It is therefore much brighter than the torch function of many smartphones. No more annoying cables: The torch is conveniently charged via the integrated, fold-out USB-A interface. With its compact housing made of brushed aluminium, the K4R combines high-quality optics and haptics. This makes it ideal as a stylish and practical accessory for the key ring. https://elecena.pl/product/21018630/502575-led-torch-k4r-key-ring 2022-06-16 https://elecena.pl/product/21018630/502575-led-torch-k4r-key-ring 2025-04-05
