This product works well; no problem. Secondly, I ordered it for my and my Note 3 Note Pro 12.2, and he had to find a mini USB cable in addition to the electricity supply, it does not work otherwise. Chargers Cables these 2 devices are USB 3.0 and therefore larger than mini USB. It is better that the seller would warn to proppos need a mini USB cable to the devices by walking the USB 3.0 cable as Note 3, Note and Note 2.12 pro-Tab (2014).
