Samsung 1.5m original data cable, 1A current charger, USB tester, test result 4.80V 0.92A 
Orange data cable, 1A current charger, USB tester, test result 4.22V 0.81A. This cable quality is no good. 
Mobile power discharge capacity test
Beginning discharge is 0001mAh 
After 10 minutes the discharge capacity is 0164mAh
We conclued that the charging current is 0.98A, after 10 minutes the discharge capacity is 164mAh.
Note: This data is mobile power discharge capacity, not battery capacity. According to our experience, the mobile power discharge capacity is about 1.9 times of the battery capacity.
