Read fully what "jokiin" is saying.
Providing that the only thing connected to the camera is the output plug from the power supply you could not cause damage to the camera.
It looks very much like a fault with either the camera or PSU.
As far as the fuses are concerned, a fuse inserted into an external circuit is there to protect the cable following it. It is usually chosen so that some protection is also offered to devices connected to the cable, but if these devices need protection that should be supplied locally.
The rating printed on a fuse does not indicate the voltage supplied by it, only the rupturing value of the fuse.
As you were using an extra fuse in a piggy back type of holder this is the fuse that will protect your camera circuit.
Did this fuse break when all of this happened?
From what you have told us it looks like a fault with the camera, or more likely with the USB lead supplying the power to it.
See if there are any signs of burning at the connection into the camera and the connector at the end of the lead. You may find the camera is still working.
Once all this has been tried get in touch with the supplier and see what their response is.
Good luck.
