Why we need UPS for WiFi Router

We can’t live a single moment without the Internet now. When there is a power outage in our locality out home WiFi router gets powered off. To use the Internet then we need to give power to the router. Either we have to have an inverter in our home or have to use a 12V battery for it. Both are cost-effective.

In this way, you can make UPS for your WiFi router very easily. Only one problem you may face. When a power cut occurs, the router will reboot once because of slow switching of the relay & power bank takes half a second to power up. Still, it is better to wait 2-3 minutes for Internet rather than 1-2 hour no Internet.

Power backup time

Back up time of the UPS depends on the battery mAh of the power bank. General 10000 mAh power bank will give you 3-4 hours of power backup very easily.
