Was in Target for the 30% clearance and noticed this power bank has also dropped to $48.30 in price. Same as the one previously on OZB here but with further discount:

Looks like it has selectable outputs and pins for the laptops too on top of the USB output as well as the battery jumper function. Not bad price imo.
Any reviews on these?
