It works very well. Nice cool blue color with an indicator of how much voltage is available. If you do use something that pulls hard like a car seat that heats up, an electric kettle, it will not do much for the other port if you are charging your phone. It basically will keep the phone where it's at and just maintain a balanced battery, meaning if it's at 80% it will stay there while using the heavy pulling item. Voltage dropped to 12.8 when using a heavier pulling item. But, definitely worth the money and it does work great! It tilts and does have some flexibility but not 360.
