If you’re not one to regularly replace your smoke alarm batteries, or are just tired of messing with it, the DuPont Self-Charging Smoke Alarm eliminates that hassle by recharging itself. Mounted into a ceiling-mounted light socket, it automatically charges up whenever the light is turned on.
To test the alarm, simply flip the light switch on twice, and if its 85dB alarm goes off at an inopportune time, flip the switch three times to shut the thing up. It’s available now for $33.96.
