Edit: I read on the description on Amazon that it will charge the iPhone fully once. I'll have to test it out again! I probably didn't look at it very scientifically.

2600 mah should easily charge an iphone completely.

for form factor check out the monster powercard. it's 1,650 mah but a nice form factor. just need to have a cable with you also which is really the problem with most of these portable batteries.
