Assuming 90% efficiency you need at least 10000 MAh to get 3 full charges.</P><P>But I would go for something at least 12000 mAh to avoid killing powerbank itself. It should also have 1500 mA or more maximum power output.&nbsp;</P> Sat, 11 Oct 2014 12:36:09 GMT https://community.sony.pl/t5/xperia-archive/power-bank-thats-compatible-with-my-xperia-z1/m-p/3280418#M418819 SergioPL1 2014-10-11T12:36:09Z
