HUAWEI has recently launched a 7A braided data cable (Max 140W). Constructed from silicone and woven yarn, the cable boasts outstanding wear resistance and durability while maintaining good flexibility, balancing aesthetic appeal and comfortable handling.
In terms of performance, the data cable supports a maximum current of 7A and works well with various HUAWEI fast chargers. It is also compatible with fast charging protocols including PD, QC, PPS and UFCS, enabling fast charging for devices running HarmonyOS, iOS, Android and other operating systems. It meets the fast charging requirements of laptops, tablets and smartphones from different brands. ChargerLAB will now tear down this new HUAWEI product to examine its design and craftsmanship.
Disassembly of Huawei 7A Braided Data Cable
Remove the shell of the data cable terminal. A metal steel sleeve inside provides enhanced protection.The two ends of the steel sleeve are treated by injection molding.Remove the black plastic, and you can see that the steel sleeve is spot-welded to the metal shell of the USB-C male connector. The braided outer jacket of the cable body is secured with metal clips.Remove the metal sleeve and fill the interior with hard sealing glue for protection.
Remove the hard sealing compound. An E-Marker chip is mounted on the front side of the small circuit board.Solder the wire cores on the other side of the small circuit board.The pins inside the USB-C male connector are gold-plated.The pins inside the USB-C male connector are gold-plated.Remove the terminal housing on the other end; it features the same structural design inside.

Disassembly Summary
This Huawei 7A braided data cable features an outer jacket made of custom-selected yarn, which resists deformation and discoloration. It delivers a smooth, comfortable hand feel and does not fray easily after prolonged use, boasting a stylish and refined overall appearance. The 1.8-metre cable length caters to study and work needs in locations such as libraries and cafes. Furthermore, Huawei thoughtfully includes a high-density silicone cable strap for easy storage and portability.
The cable has passed rigorous tests: 10,000 cycles each of 90-degree bending resistance, tensile durability, and connector plugging and unplugging. Actual tests show it delivers 89.28W fast‑charging for the Mate 70 Pro+ smartphone and 130.58W fast‑charging for the MateBook X Pro laptop, with reliable quality and performance.
Disassembly reveals that the internal circuit boards at both end terminals of the data cable adopt dual protection with hard encapsulation glue and steel sleeves. Meanwhile, the steel sleeves are spot-welded to the metal shell of the USB-C male connector to guarantee strength, and the internal pins are gold-plated. A high-density shielding mesh is built inside the cable body for anti-interference purposes. Tensile yarns are also incorporated, combined with a high-strength braiding process to improve the overall tensile resistance and flexibility of the cable.
