1 Someone charged the watch with a power bank.
2 The power bank can charge the watch through the USB port, because the watch usually has a USB charging port. The advantage of charging the watch is that it can be easily carried, and it is very practical to charge the watch anytime and anywhere, especially in outdoor activities or travel.
At the same time, the capacity of the charging bank is generally large, which can provide lasting power support for the watch.
4 However, it should be noted that the output current of the charging bank and the charging requirements of the watch need to match, so as to avoid problems in the process of charging the watch. In addition, some watches may have limitations on external charging sources or do not support external charging, so it is best to check the watch's manual or consult the relevant professional before charging the watch.
