This is the Lighter Plug USB I use with a USB to Mini-USB cable. Works perfectly.Maybe someone knows if there is a car charger that could be used for the Darwin, my power is knocked out a lot due to storms in my area, sometimes 5 days, so i would be grateful to know. Thank you.

It's limited to 10 watts though.
