If you've ever wandered around a parking lot on a freezing night, begging strangers for jumper cables and a jump start, you'll see the value in this Duracell Powerpack 450 with Voice. It can talk you through the whole jump-starting procedure, getting you back on the road in no time.

This way-cool device goes way beyond that, with an onboard air compressor to pump up a flat tire or an air mattress. It'll also serve as an able substitute for a power generator, cranking out 340 watts of continuous AC juice (450W peak), enough to run a laptop or a small TV. It even has a USB port to charge up most gadgetry. Looks like $150 worth of winter security to us.
