I paid $13.64 for two of them with amazon prime free shipping awhile back. I use them with a 64gb iPod touch and a 32gb iPhone 4. I would say it is worth maybe half to 3/4 of a charge. Left alone it discharges fairly quickly so I leave them plugged in all of the time until needed. Having an extra power source is handy when you are dead in the water and have to run.
I also have the altoid tin charger which is much better but I think I paid around $40 for that and it is more bulky.
