[pct-l] external battery

[Ginger Hayes]

Does anyone have any experience with the Brunton Ember power pack?  I can't
find much information online, and only one review.  According to their
website it just became available in January.  Looks like it could be a good
choice.

I'm also looking at the Brunton Inspire and the Mophie Juice Pack
Powerstation.

Anyone with an opinion they would care to share?

Thanks,

Ginger
