Just bought Iwo p48 18000mah.
Couldn't try the capacity due to takes long time to test but charging speed is slow.
For 2.1A & 1 A output also get 700-800 tested on note 2 using galaxy current charge lite.
To me quite disappointing.

My ciplak 12000mah(2000mah real capacity) power bank can give me 1800! Same with my original charger!

If you want I sell mine to u at 130 , used 1 week only! Still 5+ month warranty.
