So i was looking for a power bank to power a dash cam at night so it doesn't run battery down. ordered the other one, and it had a bad port. yours worked right out of the box. and fast charged even better.

Haven’t tried it yet. Was not “slim” as described. At least not what I would define “slim” to be. It’s like over an inch wide
