KingCom Speed Charging Cable

My charger cable was cut in half about 2 months ago and I bought a generic charger cable from "tiangge" stalls and I thought it was a good deal since it was dirt cheap! But Oh BUT! It takes the whole day like 10 hours to have my phone fully charged! I don't know why it takes that long. So this time I saw a speed charging cable from KingCom which costs a little more but I decided to buy it since time is so important and it says on the box that it is a speed charging cable. Watch the video below and find out if it is worth to buy in case you also need one.
