Wurkkos HD20 is a professional, bright angle-head flashlight and toollamp, designed for multiple indoor and outdoor activities like camping, hiking, fishing or hunting. With the supplied headband it can also be used as a headlamp. It is powered by a single 21700 lithium-ion rechargeable battery, is rechargeable via USB-C (both type A-C and C-C cables) and can also work in reverse as a powerbank to charge external USB-devices. 18650 batteries can be used as well. Moreover, HD20 comes with an adjustable lanyard, a mag¬netic tailcap and a sophisticated user interface for flexible and convenient one hand operation.
