Compact and versatile
A great power unit, which I use for a flashlight head and a bike light. Small enough for easy-carry in a pocket. With a separately purchased handlebar holder it makes a versatile and strong bike light. The plug in capacity for charging a cell phone or other accessory is also very useable, especially on long, or overnight trips.
