Charging is most efficient with a 5V 2.1A Max output power supply, but please do not directly connect a charger with a power supply higher than 5V 2.5A. 

The inside display panel comes with a power cord" 

The power adapter displays 100-240V, but you can choose to use the power adapter or battery. The kit does not include the battery and needs to be purchased separately 

Hi. Yes it is suitable , in fact , that's the very camera I'm using it on. It rather depends what you mean by 'fully'. The camera will not use any of it's auto features because the lens is totally manual , there is no metering and also the focus aids don't work. However , the camera takes pictures with a tamron lens perfectly well . Set it to 'M' on the dial and then set your own shutter speed and aperture . It will look a little dark through the view-finder ( at least it does on my 135 telephoto lens ) but the pictures come out fine . 

Yes, it is indeed Nikon f mount.
