The Thrunite TC12 is unique in that it has a built in battery charger. Plug in a micro-USB cable to charge the flashlight. While charging the brightness selector button flashes. Being USB rechargeable makes this is an excellent truck, car or nightstand flashlight design. Keep the Thrunite...

I carry a Olight S10R Baton on a daily basis. Personally I just feel naked when out and about without a flashlight, been that way for years. Anybody else an addict like me? :D
