it worked like a charm for the first 6 weeks and then yesterday it DECIDED not to charge anymore my Samsung Galaxy Tab 1. The original cable from Samsung is quietly working so the problem is definitely with the cable. I contacted Amazon and i'll see What They reply ... In the mean time, I would recommend NOT to buy this item and stick with the "way too short" original Samsung cable. I am also a bit upset at Samsung to sell Charging Cable so short and providing tablet with only 16GB of Ram ...
