Unlike the original raspberry pi model b the raspberry pi 2 model b cannot be back powered via the usb ports or at least can t be booted in this fashion.
Raspberry pi power bank pass through.
The 5v gpio pins on a raspberry pi are connected to the 5v rail.
So you can hook up the gpio 5v pins to a 5v source and feed energy directly to.
If done right pass through will move power directly from the wall outlet to the connected device via the power bank.
Typically they provide the remaining power from the raspberry pi that isn t being used to run the board itself.

I use my pi b in my car to do timelapse photos powered off a cigarette to usb plug however i found that sometimes the plug would fall out and thus power down the pi.
I also had the problem that even if i wanted to stop for 5 minutes which meant turning the engine off again.
Pretty impressive and way longer than i expected.
Pass through technology itself is in essence a series of power regulating circuits inside a power back that helps match the draw of energy needed by an output device to the amps being pulled from a wall outlet.
Zero2go work in pass through when input voltage is less than 5 5v and in step down mode when input voltage is higher than 5 5v.
If you are using a hub that backfeeds to the raspberry pi and the hub experiences a power surge your raspberry pi could potentially be damaged.
This means that the hubs will power the raspberry pi through its usb cable input cable without the need for a separate micro usb power cable and bypass the voltage protection.

Take a look at most raspberry pi robots and you ll likely see one.
A more technical and dangerous way to power the raspberry pi is via the gpio pins.
Mode 1 micro usb port 5v 2a the first recommended and easiest way to power the raspberry pi is via the micro usb port on the side of the unit.
Zero2go has quite wide input range 5v 26v so it is will be convenient to power your raspberry pi with power bank li po battery pack solar panel car battery or different kinds of power adapters etc.
