Use 2A load resistor to connect with Salcomp (a Nokia company) charger, the output and voltage is 5.01V 1.89A
Connect 2A load resistor and mobile phones to Salcomp (a Nokia company) charger , the measured value of the maximum current and voltage is 5.06V 2.20A, very good charger.
Mobile power connector USB HUB for mobile phone charging, the measured voltage and current values 5.00V 0.44A
Mobile power via USB HUB, connected to the 2A load resistor and mobile phones, the measured value of the maximum current and voltage 4.86V 1.96A, still good mobile power.
The second group of pictures USB data cable tests
1m original data cable of LG, 1A current charger, USB tester, test result 4.8V 0.92A
1.5m original data cable of Samsung, 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.
