Black Anker 10000mAh power bank with blue sticker

Found a black Anker 10000mAh power bank this afternoon around 2:15 PM outside the Empire Mall at 4100 S Louise Ave, Sioux Falls, SD. It's a matte black rectangle about the size of a small book, with a small dent on the top edge and a bright blue sticker featuring a white star on the front. It has two USB ports on the side and a small LED indicator that glows when charging. It was on the ground near the mall entrance by the parking lot; I grabbed it hoping to help find the owner. If it's yours, I'll keep it behind the Lost and Found window at Empire Mall and coordinate pickup here in South Dakota.
