Editor's Pick: When replacing an outlet or checking which circuit is broken at home, just hold this near the wire to detect power without stripping the insulation. It comes with a screwdriver on the tail, so you can tighten a screw after testing. The screen shows percentage readings and has a backlight, making it easy to see in dark breaker panels. It automatically shuts off after five minutes of inactivity, so you don't have to worry about draining the battery.
