Wrong battery included to fit this strap - ATN Extended Life Battery Pack with MicroUSB Cable

The stitching at the USB end of the pouch won't let the battery go all the way in and it is a stretch to zip it closed. When it is zipped closed the zipper separates behind the zipper pull. If the USB cord could come off of the center of the battery like the battery in the first photo with the neck strap it would work. The battery that came with my order has the USB coming off-center similar to the second photo of the battery and is binding on the stitching.
Also, the instruction pamphlet that came with the battery is in Chinese so I couldn't figure out how to shut it off. I guess it will be dead by the time OP gets it back.

Also, the neck strap being 3" wide and not being able to bend/flex because of the battery at the back of my neck is very uncomfortable.

I am returning this and will probably try placing a 20,000 mAh battery that I have in a belt pouch and use a coiled USB cord.
