The shorter the cable length, the faster the charging, for example, of a mobile phone. (I mention this as a user of cables with lengths of 5, 3, 2, 1.5, and 0.5 meters respectively).
With a 3000 mA battery without quick charge, it takes one and a half hours to go from 0% to 100% with the 0.5-meter cable. With the 5-meter cable, even after 5 hours, it hadn't reached halfway. Just for comparison.

In a few words, excellent.
The microUSB connector fits a little tighter on devices than usual, which is also considered positive. The cable feels generally thicker and less flexible than the previous ones I had.

WITH OLD CABLE
I tested 5 different phone and tablet devices, using all combinations of 4 different chargers and 6 different cables that I already had. The test was conducted by inserting a special device between the charger and the cable, which measures the charging current in Amperes.
The results surprised me.
Regardless of the output capability of the chargers (1A, 1.3A, 2A, branded 2A), and also regardless of the device (all tested devices were charged from 50% to 70%), the results varied depending on the cable used, specifically out of the 6 existing cables, 5 charged at 0.3-0.4A, while one charged at 0.8A.
Clarification: none of the existing cables were purchased separately, but all were included when the corresponding device was purchased.
Because I wanted to replace two of my old cables due to external damage, I bought the Cablexpert CCC-AMBM-0.5M, relying solely on the positive impression I have of this brand.

WITH THIS CABLE
The results with the new cable surprised me again, this time pleasantly.
With the new cable, the charging current was 1.1A on the small charger and 1.3-1.5A on the others.
This means that now I can charge my devices 4 times faster, simply because I changed the cable.
