I bought this cable to charge tablets; my kindle fire tablet and LG. There is a contact problem with the kindle, micro USB socket fleet, and it must be put in a certain position for it to load, it seems to me doubtful. And in terms of LG tablet, this cable should not charge enough intensity, the tablet reads: "connected to a low voltage charger." Charging is done anyway but not in operating mode. Is the defect due to the cable length? it seemed practical to have a rather long but if the problem comes from there, it might be necessary to specify in the specifications.
