Finally, no harmful interference to radio more!

This is now my third USB car plug. The first was quite pretty and chic with blue LED - but too weak on the chest. With 500mA charging current have my smartphone, I also like insets in the car as Navi, more power than the adapter capable of supplying. This means that the battery has discharged -despite Netzbetrieb- slowly.

The second adapter looked a little less fancy, but had 2000mA power. The battery is now charged despite navigation, BUT: I had extreme interference on the car radio (Skoda Octavia).

By chance I found out after months in a review of this second adapter to the USB plug Katinka. Therein someone described the same problems that I had. He recommended the Katinka USB adapter, I have then ordered me without further ado.

And indeed, I have no more disturbances on the radio! In addition, the adapter sunk relatively deep in the cigarette lighter, what looks good for my taste. The device has no LED (I need not personally), but 2 USB ports. Thus, while driving not only the own device to be powered, but also the passenger :-)

Conclusion: For those who need a powerful USB charger in the car and that's why disturbances in the car radio have -> Buy! :-)
