It s a tiny low cost low power mini computer with mini hdmi and the same 40 pin gpio that all other raspberry pi boards use.
The gpio pins can draw 50ma safely distributed across all the pins.
The power requirements of the raspberry pi increase as you make use of the various interfaces on the raspberry pi.
But how much current in milliamps or amps the pi requires to function depends on your usage.
I use a 5v 2 5a power supply for my pi 2 but the zero should take much less power than that right.
The recommended amount is between 700ma for a raspberry pi model a and up to 2 5a for a raspberry pi 3 model b see power supply requirements in the magpi issue 56 page 39.
An individual gpio pin can only safely draw 16ma.
