In this video, I will show you how to make a mini UPS for WiFi Router by using a Power bank. The UPS will automatically switch from mains to power bank during the power failure. A 12V relay is used for the changeover, which may cause the router to reboot once because of the slow switching. Your power bank will take around half a second to power up.
