"Looking for renewable power to recharge your device while on the road? Use our USB Mobile Power Pack (MPP) with our Lil’ Sync® Retractable Sync-N-Charge Cable to charge your HP/Compaq iPAQ 110. Designed with the mobile user in mind, it utilizes Li-ION battery technology and fits in the palm of your hand. We've stuffed a full 4400 mA capacity into this small package. You can recharge the MPP via your computer's USB port or you can use our USB AC Adapter or USB Auto Adapter. The MPP has a three level LED indicator system that keeps you apprised of the level of charge remaining." 
PPC Techs released a new product today, an external battery that will charge pretty much anything that uses USB power (Zune, phone, MP3 player, etc.), and I had the chance to test it over the past few days (mine lacks the swanky "Lil' Sync" logo however). Look for my Quick Look review on Monday morning. Have a great weekend everyone!
