Ah I had presumed that because they say it's designed for led lights it wouldn't provide the watts. Found this in the faqs, Classic mobile phones and GPS devices work with economic power consumption. You can power them with a suitable charging device and a SON 28 or a SONdelux just as well. If you would like to charge a power-hungry smartphone at speeds lower than 20 km/h you should rather go for a SON 28. At speeds higher than 20 km/h you may charge a modern smartphone by using a SONdelux together with an efficient charging device.
