> Almost all consumer power cords in the USA have the same voltage and nearly the same amps Input voltage yes, output voltage no. A USB power brick will output 5v, a laptop power brick might be 12v or 19v. Amperage also varies, but that's less critical provided there's more than you need. Polarity is also an issue, annoyingly there isn't an absolute standard on which side of the DC output is positive and which is negative. >Do not try to nigger a washing machine cord into a USB phone cord, if that is even possible. You guys have DC washing machines?
