The size of this powerbank is the main thing that attracted me. It was a great purchase until a friend dropped it once or twice and the metal collar that wraps around the top came slightly loose and makes a constant rattle sound now. And the bottom section of it also came loose on one side. Apart from these annoying things it's made of nice feeling materials just not very sturdy if dropped. It charges my iPhone 8 extremely quick and the remaining charge display is really good as well.
