Customer Review

I received this external battery a few days ago and tests are disappointing to say the least: the fully charged external battery only recharges the battery of my Sony Experia Z2 halfway. I plugged the external battery when the battery of my phone was 4%, then I left the phone charging without using it at all. After a few hours the external battery was drained and smartphone battery was charged at 50%. So a full charge the external battery does not even load half the battery of a smartphone. It's very disappointing as performance!
