Query: Does not work with any case on iPhone

I had very high expectation. I need this kind of product to declutter my desk. However, the CyperPower will not connect with the iPhone if you have a case on it, no matter how thin it is. This is a significant design failure. It's a non-starter for me. I have to take my iPhone off the case each time, I woulr rather use a regular USB cable to connect it to my MAC.
