With this USB cable, devices with a 5V power supply, such as USB hubs or speakers, can be powered. It is the perfect solution for mobile applications, as there is no need to carry a power adapter for charging 5V devices. Gold is key: The gold-plated connectors protect against corrosion and enhance conductivity. This ensures fast and durable data transmission. Copper "inside": The most important component of a cable is the choice of inner conductor material. The copper used here offers the best transmission properties. In addition to low impedance at high frequencies, copper is characterized by high mechanical durability, flexibility, and longevity. Furthermore, the line resistance is significantly lower compared to cheap steel (CCS) or aluminum (CCA). This guarantees excellent and secure data transmission quality. Each cable is individually tested: Renkforce stands for quality, so this cable is tested for quality and functionality after production.
