Charger case Battery Back for M9?

[sjcdal]

This has been the easiest method to get extended battery time on my last few phones. (M7, M8).
The one for the M8 ALMOST fits..but just like the car dock, the actual power plug does not QUITE go in deep enough to connect.

Has anyone found one like this for the M9?

The ones i have tried were all cheap crap. Either plastic was cheap, or the battery capacity in the cells was lower then advertised.
I gave up after 2 or 3 different ones.
