This heavy-duty USB sync/charge cable (M/M) connects your smartphone, tablet, MacBook, Ultrabook, Chromebook or other USB-C device to the USB-A port on a computer, car charger or wall charger. It allows you to charge and power your USB-C device, while simultaneously synching and transferring data at USB 2.0 data transfer speeds up to 480 Mbps. The cable is backward compatible with previous USB generations, allowing you to use it with older equipment. Charging cables used with mobile devices are often pulled, strained and generally abused, sometimes to the point of failure. To counter the stress of daily abuse, the super-robust U038-003-GY-MAX is constructed using UHMWPE and Aramid fiber to reinforce the conductors inside the cable. The double-braided nylon jacket helps maintain top performance and long life, while the enhanced UHMWPE and Aramid protection stands up to the strain of rigorous and frequent use. Integral strain relief gives the cable extra flexibility, reduces stress, and helps the cable move freely without cracking or breaking loose from the connector. Unlike traditional USB cables that connect in only one direction, the reversible USB-C male connector plugs into a USB-C or Thunderbolt 3 port in either direction for a fumble-free connection every time. The cord's three-foot length helps reduce cable clutter. Reversible USB-C plug connects in either direction for immediate no-fuss use Extra-strong cable construction helps prevent fraying and loose cable connectors Supports USB 2.0 speeds up to 480 Mbps to ensure efficient charging and data transfers Integral strain relief helps cable move freely without stress or cracking Engineered using UHMWPE and Aramid fiber to stand up to frequent and rigorous use
