Blue Anker power bank with red A1 sticker

I found a blue Anker 10000mAh portable charger this afternoon around 3:15pm in the parking lot behind the Walmart on Main Street in Sterling, CO. It's in decent shape with a few light scratches on the shell and a small dent on the bottom corner. The top edge has a bright red sticker with 'A1' written on it, which I figured would help identify the owner. It still powers up and delivers a solid charge, so I figured someone might be missing it. If this is yours, describe the A1 sticker and the last charge you recall, or any distinctive features like the case texture.
