Re: battery box for USB

Here's a similar gadget that costs less.  The Semsons Pocket Power
Bank has space for four AA rechargeable cells.  It draws power from
110 to 240 volts mains power outlet.  It discharges the cells through
a regulated USB connection.  Price is $22 instead of Sony's $35, but
does not include AA cells.

If you already own a AA battery charger, then here's a battery box
that only discharges the batteries to provide power to USB devices. 
Price: $10
