I deliberately chose the original HTC charger, because I wanted to play it safe, it fits my phone, and I thought that would be best. Unfortunately, I find a little on the short cable. One can still draw, but it is then too much on voltage. I have my phone now hung quite far down in the middle of the windshield - that's enough ... from the charging power, I am far too little disappointed. With activated Navifunktion the phone battery will lose anyway - though less than usual, however, I would have liked that it remains the same, or perhaps even more is ... I have no comparison to other cables, so I can not say whether this is a shortcoming or if that's just always so. If this cable is broken I would not directly buy again, but first try a different manufacturer.

I am absolutely disappointed with the charging cable. I have not often used it and now it has a loose connection. The red LED flashes only occasionally to take as it is common and remains lit when charging. The connectors are plugged in correctly on both sides but unfortunately the charging process does not work - instead, the phone discharges ever. A message to Amazon for return is sent. I advise everyone to buy it from this charging cable.
