Yes, there are 3m cable, with which you can recharge a smartphone smart. This one, for example. Accordingly powerful chargers, it is able to load Galaxy Note II with the full 1800mA charge current, a Samsung (more can the Note II not). This has yet managed any other 3m cable with me. This performance you paid for, however, with the cable thickness: 5mm is already a house number. The cable seems a bit bulky arg (there are thinner power cord :-), but is still quite pliable. The male acting solid, but are made of soft plastic. And one more thing: there's this cable with right angle plug and straight plug. The angle plug is nice (the cable is then right away), but not with a Samsung Galaxy S5, for there is the jack cover in the way.
The data cable I have not tested it because I do not need such a long cable.
