Valent housing, blundered inside?

Now the package was very good. Also the charger itself can look very sophisticated.

Unfortunately, however, I realized that at the marked with the "Fast Charge" USB port my phone still loads with only 500mA and therefore becomes empty when navigating the battery.

So I went and grabbed my instrument and have measured it. The middle two USB pins (data pins) must be short-circuited, so that the phone recognizes the charger as such and then at full power charges the battery. It was in this charger unfortunately not the case. If the two data line is not shorted, the phone assumes that it hangs on a PC and therefore only charges with 500mA. This is because since the USB2 ports are specified for a maximum current of 500mA and at higher current the USB controller of the computer may break down.

Amazingly, the two pins at the 2nd USB port, however, are short-circuited. The two ports are thus reversed.
Apparently the internal wiring has been fudged when assembling the device or soldering.

I have now made a special USB cable for charging in the car. This I have cut open and shorted the two data lines themselves. Now the shop is on two ports at full power.

I think TomTom should rectify as in quality control.
