Hello I purchased this product from amazon: https://www.amazon.com/gp/product/B00CGQH1RQ/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

I’ve spliced into power and have confirmed polarity and voltage using a voltage meter.

When I plug in any usb device it receives no power. What is the next troubleshooting step?

Thanks
