Don't assume it's 5V just because that's what the standard says. Yes, the USB power spec says 5V, but there are many 3rd party USB chargers these days that are built for specific devices (cell phones, MP3 players, etc) that DO NOT follow the spec. The power they output works fine with the 3rd party device they were designed for, but it will not necessarily be even close to the official spec.
There are many cases of devices which have adopted the USB plug format for their cables, but don't adhere to the power standards.
