My phone (a pretty new N6) won’t make it a full heavy use day. I have a 10,000 mAh Anker battery pack that I edc and use, but it’s a bit of a  to charge and a bit overkill for most days.

I’m thinking seriously about the smaller 18650 Anker battery pack…but it would be really convenient if the thing had a place to hook a lanyard or d-ring so I could just hang it off my phone case and protect the USB port.

Does such a thing exist? I’ve found a couple, but they’re bigger than the phone.
