Thanks for sharing your product review.
I would like to present our deepest apologies for inconvenience caused. Would you try original Apple lightning cable, so we may better investigate if the problem is from hub or not.
Meanwhile, we hope you did not miss the listing note as "This hub is not designed to serve as a standalone charger and will not charge an iPad tablet or any other device with non-standard charge requirements.
", that is to say, normal USB data-transferring port is not supposed to used as a charging port, but you may find the specially-designed charging port from other Anker's series like Anker® USB 3.0 7-Port Hub with 1 BC 1.2 Charging Port up to 5V 1.5A, 12V 3A Power Adapter Included [VIA VL812-B2 Chipset]
To speed things up, could you please email us directly at email@example.com with your Amazon order #, we will try our best to assist if you have any suggestion.
