Many of us like to leave our computers running all of the time, but that uses a ton of power. And even if you want the computer on 24/7, there’s no need to have the printer, speakers and other stuff powered on.
A new power strip called the HiSaver makes it easy to save power when you leave the room. The HiSaver Powerbar features a remote motion-detecting sensor that sits on your desk. So when you leave the room for at least ten minutes, four of the outlets turn off automatically to save power.
