In this DIY video I will show you how to make use of a Power Bank as a UPS (Uninterruptible Power Supply) for your Wi-Fi routers or Security Cameras. Any commercially available Power bank cannot be used as a UPS even though it has the pass through charging function. This is because when the Power bank switches from its batteries to the input, the output is interrupted momentarily, forcing the load to reset.

I have finally found the Power Bank with a large capacity that can be used as a UPS for any 5/9/12/15/20V device. This power bank does not interrupt the output power while switching. It also has simultaneous PD/QC charging and discharging functions making it suitable for any DC load such as routers. I will show the schematic of the DIY UPS and compute the amount of backup time in this video.
