The Smart Backup Battery for iPhone, iPod by Richard Solo is a great accessory for those who travel or need additional power for their iPod or iPhone during the day. It is definitely small and light enough to have in your laptop bag. The Smart Backup Battery is compatible with the iPhone and all iPods with the standard Apple 30-pin connector. It can potentially reduce the number of charging cords.
I dont know about know much about iPods or iPhones but thought this would be interesting since the contest is for an iPhone. Thought I would share this with everyone here.
