If you experience frequent power outages and are looking for an economical emergency power backup solution for your Wi-Fi Router, turn to power bank. This article explains how.
Most Wi-Fi routers for home use have a power receptor of 5V. I have used a D-Link AC750 Dual Band Wireless Router for this demo. Also, most power banks come with a 5V battery. If your router’s power receptor is for example a DC 12V, you can look for power banks with USB output of 12V.
To connect your power bank to the router, all you need is a USB to DC convertor or cable.
Above cable should be available on most ecommerce stores or you can look for the cable in a computer / electronics components shop in your locality. I purchased mine from an electronics component shop and it was available for a dollar! The barrel jack of the cable comes in various sizes. Hence, be sure to check if barrel jack fits in your router’s power receptor. I reckon, the common size which would fit in most routers will be 5.5 or 5.4mm (Outer) and 2.1 mm (Inner)
Now, all you need to do is plug the USB end of the cable / convertor to your power bank and DC end to your router. That’s, it!
