Recommendations for external battery packs for phones?
So I have been thinking about getting an external battery pack for emergencies. Specifically I think I want one I can throw in my coat pocket and forget about it until I need it. I am thinking something like this fits the bill:
That would give me one full charge of the phone, and is about the size of chapstick, which I carry anyways.
Admittedly, I don't know much about good brands or products in this segment of accessories, so if anyone has input on what they use I would appreciate it greatly.
