Title: USB ports work, but 12V sockets did not
Review: I was very disappointed in this. Both USB ports work fine, but neither 12V socket works. I tried it in multiple vehicles with functioning 12V sockets, so I know it wasn't the vehicle. In theory, this is great and the price was right. I wanted to be able to charge my phone and GPS at the same time, with an extra USB port if a passenger needed it, and the extra 12V port to use a power inverter for a laptop when needed.
Is the review positive or negative?
