Smartwatches with USB

USB

— the wired connection to a computer/laptop using a USB cable. A rather specific option is found in some fitness trackers and children's beacons. During working hours, such a gadget functions completely independently, and the USB connection is used only occasionally, for some special tasks: transferring collected data to a computer, charging the battery, changing some settings, etc. This is not as convenient as a permanent connection via Bluetooth. Therefore, USB is rarely used as the main connection method in wearable gadgets.
