I take this with me EVERYWHERE, I can charge my kindle, iPad pro, and my Samsung Galaxy 21 Ultra. I havent tried at the same time, inusually only need to do one at a time. If I use it down to 20% I can put it on my super fast charger and it will be charged when I get up the next morning. I really, really live this portable charger, leagues better than the one I had before. Also, the screen showing the battery percent is clear.
