Wireless Car Charger 7.5 Watt?

[Cwolk]

Does anyone know if a 7.5 Watt wireless magnetic car charger (that connects to the vent) exists? There are many car chargers available, but the ones I've seen only support up to 5 Watts. Is the car unable to support faster charging-speeds?

Thanks.

Update: The new Belkin one that will be coming in the spring seems to fit this category.

Tis not magnetic nor does it appear to use a vent clip:
