The JETbeam KO-03 holds a luminus SST-70 LED, which has longer run times and is more functional in the long run. With its small body design, this flashlight puts out a maximum of 2400 Lumens and lasts for up to 350 hours. It can be powered by a 21700, 20700 or 18650 li-ion battery and recharged through a USB-C charging port.

The KO-03 has the unique feature of providing a power bank function with the use of the battery. You can charge up essential electronics anytime with the flashlight in use. To ensure ultimate efficiency for all types of environments, the KO-03 also includes a flat and magnetic tail-cap. This can be used on flat surfaces for tail stand lighting when broader lighting is necessary. By attaching this to metal surfaces you have a hands-free lighting device.
