It has plenty of power to get the job done, the flashlight is super bright, and you can set it on a flat surface or hold it. I haven’t charged anything with it as a power bank yet. Anyway, I bought two the first time, in case the batteries didn’t last as long as I had hoped, however I have yet to use one so much that I depleted the battery in one sitting. I ordered 4 more just now, 2 for my daughter, who was quite impressed with mine yesterday, and two more as back ups for myself. I didn’t even realize when I ordered my first two a few weeks ago, that they were the number one in personal fans, but I can certainly see why. Go! Get you one or more!
