No need for an outlet – cutting the cord on your power tools will make tough jobs a cinch and quick jobs even easier. A new breed of miter saws, drills, nail guns, and sanders can complete tasks just as well, if not better than your old-school set until the next recharge. And without all that clutter to trip over, you'll keep your sanity (and your fingers, too).
Black+Decker AutoSense Drill/Driver
For anyone who's ever stripped a screw with a power drill, this 20-volt tool is a great solution. A built-in microprocessor monitors torque, so the drill knows exactly when the screw you're driving in is perfectly flush. The auto shut-off means you won't smash through drywall, either.
