You can connect up to four of the Kramer 25 ft (7.6 m) extension cables for a total added length of 100 ft (30 m). Please note that this setup requires that you purchase a USB-C to USB-A cable to connect with the USB-A Kramer cable(s): Owl Labs 6 ft (1.8 m) cable ; Owl Labs 16 ft (5 m) cable A note about cable length (and speed) The cables that connect USB ports to devices can only be so long before you risk some data loss during transfer. The max length for high speed devices is 16ft 5in, and for low speed it's 9ft 10in. Another thing – USB-C regulates, in part, cable length for different usecases, such as the high-speed alternative modes. You can test a cable and assume it will work. That sets the max limit The USB-C conector has an inner orange color and a full pin design. The cable length is about 1m (3' 3.37''). The diameter is about 3.38mm (0.13 inches). This is how it looks like on my hand. And the weight is about 32g (1.13 oz). Our ChargerLAB POWER-Z KM003C shows it can support 50V 5A 240W EPR. But the data transmission speed is limited to 1 Maximum USB-C cable length: 3 m, 4 m and 5 m now possible! 2 Selection of good USB-C cables for data transfer and battery charging. 3 USB-C cables with a length of 1m. 4 USB-C cables with a length of 2m. 5 USB-C cables with a length of 3m. 6 USB-C cables with 4m or 4,5m length. 7 USB-C cables with a length of 5m. USB 2.0 specification supports cable length of up to 5m (like the one included with the product). This length can be extended by inserting hubs or USB extenders. When using USB 3.0 cables, the specified maximum cable length is 3m. As with USB 2.0 cables, this length can be extended by inserting hubs or extenders. ewuoHM.
