Idea is sound, product needs work.

Whether you have it hooked up via a lower power charger, a battery pack, or fast charger, it creates an irritatingly noticeable cracking/buzzing sound while charging and playing music Tested in 3 vehicles with multiple types of midi cables. It clearly needs more shielding to prevent interference. The aux input also sometimes doesn't auto switch the sound from phone to lightning output, so you have to unplug and re-plug it. For long roadtrips, I might still use it in a pinch, but only if it survives me taking it apart to create a better housing that blocks the power bleed over. Bottom line, try a different one.
