Running out of cell phone battery power sucks but it happens to everyone, even Guydsters.  But now thanks to a tiny charger that fits on your key chain, you can get an extra boost of power.  Appropriately shaped like a jerry can, this micro charger contains a 220 milliAmp hour battery that will give you between 20 and 30 minutes of talk time, allow you to send a bunch of email, or give you a few hours of standby.  It’s perfect for those days when you wake up with a hangover and forget to plug in your phone before hitting the sack the night before.  To recharge it, just plug it into any USB port (using the included micro USB cable).  $20.
