A:Answer The one that came with mine is a "universal" power supply in that it accepts 110-230vac at 50-60 Hz. The output is 19.5vdc at 3.33 amps, giving 65 wats of power. Mine came with at standard 3 wire, 110vac cord (US style).
The connector to the computer is a generic small barrel connector. I haven't measured the dimensions, but it appears to be the size that is common on today's laptops. I'm guessing that the OD is around 3mm.
