Creative Sunday: DIY Power Backup System
I got my new internet router to solve the issues with low range on my old one. A new issue arose with this one, however, and it's with power.
Electricity is nothing close to regular where I stay, so it became a real issue with this new router as I could not just plug it into a power bank like with the old one. It runs on 12 volt DC power, and power banks usually give 5 volt DC. I needed to find a solution to keep the new router running much longer, especially during blackouts.
I improvised. I thought of the things I had at home, and then I remembered that we had a car battery and a generator battery that are 12 volt DC rated, and then a light bulb came on: a simple circuit to draw power from those batteries into the router should suffice. And, considering that they were even bigger batteries, I had nothing to worry about.
The video here is a concise compilation of clips from when I was designing. The simple circuit to do my bidding.
This is super creative, I need to come learn some stuffs from this Engineer.
Nigeria and electricity aren't friends but with your new source of power, you don't have to wait for them to restore power. Great job sir, I learned something.
I actually use the same system to charge my phone and other similar devices. The idea came to try it out for my router, and, thankfully, it worked!
For three days now, no electricity. Makes me regret getting a meter and joining the grid on electricity. A good solar power system would have been a better choice. This is Nigeria, sadly.
This is really nice! Getting to use a 12v battery. You have talked about it with me. How do you plan to charge up those batteries after? Do you have a battery charger?
I accounted for charging the batteries in the circuit. In the circuit diagram, you'd find the voltage source to be the 12v adapter.
It's delightful watching this bro.
Creativity!!.... An engineer indeed.
I can't imagine the high trend of creativity and productivity that will happen in Nigeria if the problem of electricity is solved.
Hey, man! Great to see you on Hive and actually know that it's you. You might want to update your DP so you don't keep lookin weird.
Thank you for the kind words.
You're welcome boss.
Thank you for the advice, I'll do that soon.

I am impressed. You are so creative and resourceful. How will you charge the battery when it dies?
Thank you, MoMo!
There is a 12v DC power adapter from mains that's in the circuit to charge the battery when it dies. It's only 2 A rated, though, and it'll take too long to bring it back up. It'll only charge the router battery just fine. Our gasoline generator has the right outlet (12v DC 8.3 A) to charge it, so I'll use it to recharge whenever I need to.
