There are different ones made, yours probably has a plastic piece inside the plug and wont run your PT, AS WELL AS THE post below saying it's not srtong enough, it is probably .5 Amp and wont run your PT, you need at least 1Amp to run the PT however you want the 2 Amp one to really get the best performance, they also make a really nice one for the car to plug into the Cig lighter that is 2 Amp, its worth the little bit extra to get these for sure, if you search you can find deals on these too
