As pointed out above, these cables are wired so that data connections are not possible.
That will trigger the AC charging mode on most devices, allowing them to charge quickly.
My phone thinks my car charger is a USB port, so restricts the amount it will draw to 500mA, which means it actually loses power when it's plugged in and the screen is on.
If I use the Portapow cable, it draws about 1.3A and can charge while running Spotify, Google Maps and Bluetooth audio with the screen on.
