If it's a keychain, it means it's yet another thing I have to stuff in my pocket. So the only way I would consider this if it would be integrated or be part of my BMW key fob. I cannot imagine having my house keys, my key fob and then yet another item which is a battery pack to haul around with me.

If you do make it small enough to where it can be in your pocket, how will your phone charge? Would you run a charging cable from one pocket to the other pocket and walk around like that? Because if you're making it small enough, I assume you're doing that in order to retain mobility, right?

I have a mobile charger that I got for free at a trade show. It's the size of a lipstick and will give my iPhone 5S a 50% charge. Plenty to get my out of a pickle.
