Another portable power solution appears to be the Energizer XP4001, part of the 
company's Energi to Go series.  The XP4001 has two 5V DC ports that provide 
power to USB specs.  Two ports would allow you to simultaneously power the 
USBPre and a small recorder like the M-Audio Microtrack II.  

The XP4001 employs a Lithium-Ion rechargeable battery rated at 4000 mAh, which 
should be enough juice to power the two devices mentioned above for about 4 
hours.  Price in USA is about $60.
