Power requirements
The chumby uses a very standard 2.1mm I.D. x 5.5mm O.D. x 9.5mm Female (P-5) barrel connector and runs off 1A at anywhere between 6.5 VDC and 14.5 VDC. it ships with a "wallwart" power supply with US-style prongs, however, it's pretty easy to find a compatible power supply with other form factors.
