Why my MicroUSB Cable only have 4 pins ??

[AC Question]

I have a Galaxy Tab S 10.5 and the baterry take around 6 hour to charge , so I try to charge with another cable but with the same wall charger and result that the baterry take around 2 hours and a half to charge , the difference between ths two cables is that the original cable only have 4 pins in the MicroUSB and the another have 5 pins . The amount of pins affect the charge ?
Why with the non-original cable the battery take less time ? or is damaged the original cable ?

If somebogy have the same tablet please check how many pins have your cable .

Mine seems to have four pins but it's hard to see. I don't recall time it.

I do know that my phone can be charged faster using a charger with about twice the output and it does not damage the phone. But I don't know about the tab.
