Raspberry pi power bank pass through.
If done right pass through will move power directly from the wall outlet to the connected device via the power bank.
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.
With a raspberry pi 2 nothing plugged in apart from a pi sense hat i got an uptime of almost 7 hours using a power bank.
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.

Pretty impressive and way longer than i expected.
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.
You may own some form of mobile power solution to get your phone through a long day.
Take a look at most raspberry pi robots and you ll likely see one.
That same 5v power bank can be used to power a pi making it a versatile safe and affordable mobile power solution for your projects.
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.
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.
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.
A more technical and dangerous way to power the raspberry pi is via the gpio pins.
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.
Typically they provide the remaining power from the raspberry pi that isn t being used to run the board itself.
I also had the problem that even if i wanted to stop for 5 minutes which meant turning the engine off again.
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.
