In the bush which delivers 2.1A, the phone does not respond.
I am a layman, for that matter, and therefore can not judge whether it is possible that the cell phone from 2.1A of self-protection entirely seal off, but I thought so far, it would not take anyway as it requires.
For now, I forgive therefore 3 stars because I can not yet say for sure whether the device is defective or if it is to be expected that my SGS 3 Mini is not loaded at the 2.1A jack.
Tomorrow, I will an iPad and a Galaxy Tab 3 plug in and see if these devices are loaded to this jack.
If so, I will correct the rating upwards. If not, I adjust them down and send back the device.
Since the vast majority of the previous reviews seem to relate to a device with 2 sockets, this is probably fairly new with 3 sockets - maybe I'll just a Monday device caught (that would not be the first time a product in this category - a bit annoying was the beautiful!).
EDIT 4.8.14:
Today I had my iPad case and plugged into the socket 2.1A - it loads! I suspect, therefore, that the Samsung Galaxy S3 seals off from 2.1A. Often one reads, devices would always take only as much ampere as tolerated. Therefore, I am surprised a little that the smartphone get along with 2.0A, 2.1A with but not.
Maybe someone has similar experience with the device and can attest to that, perhaps even explain?
That the SGS3 Mini will not boot at the 2.1A jack, certainly seems more likely to be due to this as the charging plug.
Therefore I submit the missing 2 star now according to yet. Should there be failures or problems within two years, I will point out here.
