Yes, you can use a power bank to charge your wireless router. A power bank usually has a USB output interface, while a wireless router usually has a USB charging interface. Simply connect the charger bank to the USB charging port of the wireless router to provide it with power. This is very convenient for using a wireless router outdoors or while traveling, ensuring its continuous operation. However, make sure that the capacity of the power bank is large enough to meet the power consumption requirements of the wireless router, and pay attention to the compatibility between the power bank and the wireless router.
