Customer deception, false declaration: "Non Noise". Loud fan

Since I have long been a voltage converter operate in the motor home, which makes but fan noise, I was looking for a better one. Fan noise disturbing when at night, for example, the toothbrush has to be charged with 220V. The charger consumes very little power, but needed just 220V.

On the packaging of Winten voltage transformer is clear to read "Non-Noise". Direct to translate into "no sound". Consequently, if a fan-free operation close.

Exactly the opposite is the case. Even with directly switching the device starts a fairly loud fan running. This was also about another 3 minutes test (without load!) Way. From Non-Noise can therefore certainly not be spoken.

In a loud car might not disrupt. To operate as a battery charger overnight in a camper it is prohibitive.

The unit returns post.
