The Genesis GLSD72A 7.2-Volt Lithium-Ion 2-Speed Screwdriver is a full-featured, versatile tool that is perfect for smaller projects and home repair. Super compact and lightweight, much handier than some of the larger cordless tools with a 1/4 in. hex, quick-change chuck, 2 speeds, clutch settings and an LED work light, you get many features that you normally see only on much more expensive tools. A battery charge level indicator shows you how much charge is remaining. The tool recharges completely in 3 to 5 hours. The lithium ion battery gives you more power and twice the run time of nickel cadmium (Ni-Cad) battery, and can be stored for over a year without losing its charge. Charge it any time you want, as much as you want. It won't develop a "memory" like a Ni-Cad. Great bonus drill bit set included 8 quick-change bits: 4 screwdriver bits and 4 drill bits.
