Photon with PIR Motion Sensor powered by USB powerbank

[jonkho]

Thanks for the explanation @hootie81

I happen to saw this thread about getting 5V out of batteries, Using a 5V sensor with battery powered Photon

So I was thinking is it possible to 'trick' the USB powerbank to keep producing 5v? Again, it will be easier getting a 'dumb' USB powerbank or sparkfun battery shield with lipo battery that has high amount of mAh.

Or even using Lipo Rider Pro

I am thinking to use one of the mobile phone batteries to use it as LiPo battery.

With the photon running the battery could be drained too low and wont recharge. it depends on the type of usb power bank, there may be some protection near/built into the top of the cell, but some dont.

and there is also a few cases where the photon gets corrupted eeprom when under-voltage occurs.
