Brunton’s new Solo “Personal Power Plants” can keep you gadgets running for days on a single charge. Just plug it in for a few hours to fill it up, then plug your iPod in using the USB port, insert toothpicks in your eyelids and watch all of the Star Wars movies, twice, without interruption (except for Jar-jar).

The Solo 3.4 is a little smaller than a pack of smokes, weighs about as much and comes with an array of adapters that should get the most popular gadgets in on the marathon for about $60. It charged up my Blackberry in about 40 minutes.  It has two bigger brothers, the Solo 7.5 and 15, that add, size, weight and power for $200 and $400, respectively.
