Editor's Pick: Tired of buying cans of compressed air to clean dust out of your computer case or keyboard crevices? With 110,000 RPM power, this duster can blow accumulated dust off heat sink fans in one go, and the long nozzle attachment works great for blowing into air conditioning vents. Weighing only about half a pound (0.23 kg), it's easy to hold in one hand to clean your desk or bookshelf. When charged fully, it can run on low setting for up to four hours—enough for several weeks of daily dusting.
