Not quite Impeccable

This connector adapter I bought in combination with a RAVPower Power Bank. Even my Samsung Galaxy S3 and a Tab3 are thus just as fast as loaded with the original power supplies and even simultaneously. The device makes a high impression. From me 5 stars

I am sorry to perform an update here.
The charger seems the Samsung devices have a small problem. According to my observation, the Galaxy S3 though invites to complete, but will take longer than with the original Samsung plug-in charger.
When Galaxy Tab 3, the thing still looks different. Connected with about 35% to the charger and the next day 74% charge were not achieved until then continued the charge with the original charger to 100%.
Mir is already clear that the charger, the charging cable and the Ladeelektronic are equally responsible in the terminal for optimal charging. This is not for me to use this charger, I use the original Samsung continue.
