Defective the first time I used it

It arrived to my home in a crushed box even though the padded shipping envelope was not damaged. I took it out of the box plugged it in and then plugged it into my Apple iPad Pro. It did not charge my tablet. Then I tried it on my Apple iPhone 6 Plus. It kept making a buzzing noise and switched back and forth between charging and not charging. I am returning it, what waste of my money and my time. The reviews did not seem accurate to my experience.
