[nfbcs] USB

[Gary Wunder]

I have all kinds of devices these days which can be charged using the USB
connection. Some but not all of them come with a charger that can be
connected to AC. Given that USB supplies a given voltage and current, if
these have the same miniplug on the end, can they be used with the same
charger? Must I bring four chargers for four devices if they share the same
USB connector?
