The Hongi cable is not that bad, it's mid-tier, certainly a lot cheaper than the premium cables. that cable is part of a cheaper sub-optimal mechanical design (loose internal tolerances), then combined with repetitive torsional stress during handling, caused the defects you have seen. Unlike the Hongqi cable (which leaves empty pockets around the conductors wrapped in loose tape), premium cables use dense, pressure-extruded rubberized fillers (such as specialized EPDM or vulcanized elastomers) that are forced into every single crevice between the copper cores during manufacturing. I have this MG Charger that is really high quality, and the cable has this rough texture that is not sleek and shiny like a typical PVC jacket. the BYD free charger also has similar cable quality, but it's thinner than the MG charger cable, even thou both are the same copper sizes. ⚠️ CAUTION ⚠️ Wwhile the outer jacket isn't torn, the internal geometry of the conductors is certainly compromised. This uneven bending can lead to localized microscopic fracturing of the fine copper strands over time (class 5 strands), increasing resistance and creating localized thermal hotspots. The cable should ideally be replaced, or at least monitored closely for heat buildup during a charging cycle. You should really change that cable or the full charger.
