DuPont Self-Charging Smoke Alarm $5.99

Keeping your smoke alarms working has always involved checking to see if the battery was still working -- some people even take to using the change from or to Daylight Savings Time as a reminder to just swap out the batteries whether they're still working or not. First off, not everyone remembers to keep checking those batteries, and secondly, those batteries can add up in cost. Here's an alternative that lets you save on the cost of the batteries, and it's priced lower than you'd expect to pay for a standard smoke alarm too.

Buy.com is selling the DuPont PS-131 Self-Charging Smoke Alarm for just $5.99. That's 85% off the retail price of $39.99. Free budget shipping keeps the final price amazingly low.

The DuPont Smoke Alarm contains an exclusive 10-year self-charging power pack. You can plug it into any ceiling light fixture in your house or apartment. The power pack automatically re-charges from the household current when the light is on and powers the alarm when the light is off. The alarm requires the light to be on for just about 2 hours per week to remain fully charged, and will operate for 30 days from a full power pack without charging. It chirps approximately every minute should the power pack charge run low.

The PS-131 uses an ionization type sensor to detect the presence of smoke. Ionization-type smoke alarms are generally more effective at detecting fast, flaming fires, which consume combustible materials rapidly and spread fire quickly. As long as you have ceiling light fixtures in your home, garage, apartment etc., this is a simple solution to smoke detection needs.
