For Android devices it matters if a cable used to charge the device is a charging cable or a data cable. In a charging cables the two data connections are shorted together (rendering the cable useless for data transfer), but this fools devices to see the cable as an AC power connection and thus the battery accept a higher current for charging. The cable that came with battery performed very well with Android devices, it is a good charging cable.
The POKI 5000mAh external battery charger has one ports. It performed well using my own charging cable as well as the charging cable that came with this external battery. Even though the charging port is labelled as 2A port my iPad Mini did not perform at its optimal speed. I did get more than 1A on it, but only only slightly more according to my current meter.
To tell how various battery packs perform I measure their performance with a current monitor. The current monitor results are interesting for relative comparison with other external batteries. I test all my external batteries using the same charging cables, running the same apps while charging, and starting all tests at same charge level of the phone to account for non-linear charging. This allows me to compare different external batteries to each other keeping everything else constant.
Samsung Nexus phone:
~~~~~~~~~~~~~~~~~~~
0.95A/5.12V
(for comparison the best charging monitor result for this phone is 1.00A/5V)
iPad Mini tablet:
~~~~~~~~~~~~~~~~~~~
1.16A/5.08V (below optimal)
(for comparison the best charging monitor result for this tablet is 1.70A/5V)
I like this external battery's performance with my phone, I like its shape, and its bright charging level indicator. I was less impressed with the performance for my iPad Mini.
