The modern human’s worst nightmare: a power outage. Left without cat memes, Netflix, and — of course — Hackaday, there’s little to do except participate in the temporary anarchy that occurs when left without internet access. Lamenting over expensive and bulky uninterruptible power supplies, Youtube user [Gadget Addict] hacked together a UPS power bank that might just stave off the collapse of order in your household.
This simple and functional hack really amounts to snipping the end off of a USB power cable. The cable is then attached to a screw terminal to barrel connector adapter and plugged it into a pass-through power USB power bank. No, really — that’s all there is to it. [Gadget Addict] notes that while most modems and routers are designed to run off a 12V power supply, they still operate at 5V. He goes on to connect several router and router/modem combination units to the power bank. In each case the system appears to boot up and perform normally.
The particular UPS unit [Gadget Addict] was using has a lead acid battery that was prone to failure on an almost annual basis — which defeats the purpose of a backup power supply for even a non-critical system. This quick hack could be the ounce of prevention that offsets the potentially hours of internet-less boredom that strikes with your next power outage. An accompanying solar-powered 3D printer should also keep you plenty occupied.
