With so many electrical chargers out there for things like cell phone, digital camera, camcorders, PDAs, etc, it's tempting to leave them plugged in all the time. While it may not seem like it, most chargers draw current when they are plugged in, even when they are not charging devices. Since they spend the vast majority of their time not charging anything, all of this power is wasted. It's not a big hitter, but by unplugging the chargers when not in use, you can help save power.
