Kent - she's getting power, but the standard car USB adapters are a lower voltage and won't work in a truck. I ordered some from China once. They didn't work in my Ford truck but will work in my Chrysler 300 just fine to power my passthrough. I bought a 12v and it works great in the truck.
HippyGirl, if you have a truck, you have a 12v outlet so need a 12v DC adapter like I showed in the link above. What you are buying from China is a lower voltage rating (5v). It will work in a car, not a truck.
