Just a word of advice. I notice that you have received as part of the bundle with that, the same UK mains charger as I did. Mine was faulty on arrival, and out of curiosity before I binned it, I opened it up to see what sort of quality it was inside. It is absolute garbage in terms of its internal component quality and you should not let it near any of your electronic equipment. It also leaks RF like a sieve leaks water.
If you have a Kindle mains/USB charger or similar, then use that instead, you really don't want that adapter that ships with the C3, anywhere near any of your electronic equipment.
will any mains usb charger be ok with the c3? i have a decent motorola mains charger but do i need to worry about the output ma figures printed on the charger?
