This USB-C to USB-A cable makes it easy to charge and sync USB Type-C mobile devices using the USB-A port on your computer or a standard USB-A wall or car charger. The non-standard 4-meter cable gives you the extra length you need to overcome distance restrictions and stay connected. You can charge and sync your USB-C mobile device, in almost any environment. Even while you're taking notes in a boardroom, catching up on emails in your hotel room, or reading in a coffee shop, the connection to your mobile device will reach your computer or wall charger more comfortably. The cable has undergone rigorous compliance testing and is certified by USB-IF (USB Implementers Forum) to meet all USB 2.0 specifications. This includes all environmental, electrical and mechanical standards, ensuring a reliable, high-quality cable for all of your USB-C devices.
