Product turned on once and then not again. It wasnt securely together. I was very disappointed as i have heard great things about this particular power bank!! Hopefully they will exchange it and it will be easy. Then hopefully i can give them 5 stars

Peace of mind for devices, especially the camera in remote locales. 5 stars if it was a bit smaller. Like the four outlets

The product arrived in the nail. When I received it, the cord for charging was damaged. It was completely cut in half. Luckily i had my own USB cords and could still use the battery. Other than that, the battery works perfectly.

It died before it even charged my iPhone X all the way and it is heavier than a grand piano.
