A: Disregarding the fact of different voltages there is the power to be concerned 9v x 1A = 9W, 15V X .8 = 12W. THE DEVICE WILL BE UNDER POWER.
It is an input device.
Many times the plugs at the ends of the adapter will be different for different voltages and mA ratings. If it is the same, then look at your device (or the user manual.) It should give the input voltage and current ratings. If the amp draw of the device is greater than 300mA, do not use the ac adapter. It will damage the adapter and could damage your device. If the tuner came with a 800mA charger, then I'm sure you should go buy another for a few bucks at an electronics store.
An input device. It is because it let the source to flow.
Input
In vcd, input voltage controls the output current.e.g.jfet In ccd , input current controls the output current. e.g. bjt
No, each device has a different input and output.
A 500-1000mA input specification indicates that the device requires a current supply within that range to function properly. This means it can operate with a minimum of 500 milliamps and a maximum of 1000 milliamps. If the current supplied is below 500mA, the device may not work effectively, while exceeding 1000mA could potentially damage it. This specification is important for ensuring compatibility with power sources.
Pretty certainly no; it depends slightly on the type of adaptor - if it's regulated then you'll probably destroy the adaptor and maybe the device it's plugged unto, if it's unregulated then you'll probably destroy the device and maybe the adaptor.
If it is an adapter then logically it should be adapting from one thing to another so no the output will not be the same as the input.
No the voltage gap is too wide. If the higher voltage is used there is the possibility that the connected device might be destroyed.

A scanner is an input device because it sends (or 'inputs') information to the computer.
