45 RASPBERRY PI: NOOBS VS BERRYBOOT



my dear RPI,
pls. i hope you understand that from time to time i need
to take out your LG charger power supply,
because my mobile need some power too.

so what you do? you run without power supply?
well, now that is not what i expected from a powered USB HUB
that power supply for the hub run the HD ( via 2 USB (out) ports )
and seems to power back to the RPI via the (in) USB port too.
there might even be polyfuses 0.5A in that wires,
should be minimum one on the RPI side.
I read its not recommended to run RPI by USB because
it needs 5V, 0.7A? and i tuned speed up too??
while the 4 port usb hub power supply should easy handle 2A ( 4*0.5A).
there might be minimum the risk that RPI not run reliable,
possible damage? but what can i check?

anyhow I LOVE YOU more and more
