Thermal mitigation features may be included in a Universal Serial Bus (USB) cable assembly or in the USB receptacle portion of a device. In one aspect, one or both ends of a USB cable jacket may have greater thermal conductivity than the portion between them. The portion having the greater thermal conductivity may dissipate excess heat from the cable into the environment. In another aspect, a USB cable connector or the USB receptacle portion of a device may include a thermoelectric heat pump. The thermoelectric heat pump may move excess heat from the cable assembly or receptacle into a portion of the cable assembly or device that dissipates the heat into the environment.
