Equipped with a rechargeable 28AH battery that provides up to 600 watts of AC power, the Duracell Powerpack 600 ($130) is a “life saver” packed in a portable, rugged casing. With three AC outlets and a DC socket, this little generator provides quiet and safe indoor power for daily essential devices during a power outage. The Powerpack 600 stand-alone power source also includes jumper cables, an AM/FM radio, digital alarm clock and a built-in emergency light. [source]
