    Unexpectedly confusing to use.

    Works well, but it's a little confusing with the trickle-charge thing - sometimes it doesn't immediately charge like I think it should. The instructions are tiny and confusing. And, it didn't come with a pouch as shown in some of the other users' pictures (I asked Anker, and apparently this unit is no longer bundled with a pouch).

    No, I would not recommend this to a friend
