This is my first post here so bare with me.
I'm trying to build my own powerbank for my 12v modem because the area I live in experiences frequent and prolonged cutouts. The reason I don't want to get a normal UPS is because of the power it's going to waste by converting 12v to 220v and back to 12v.
I want to set this transfer switch (whatever it's called) up in a way that it switches to the 12v lead acid battery when the power goes out and back to the DC adapter when the power comes back up. I'm not looking for a high speed switch and I'm fine with losing internet connectivity for a couple of minutes, all I care about is making this switch automated.
So far, I have a 12v lead acid battery, 12v lead acid automatic charger, 12v modem+AC adapter and a DC to DC adjustable voltage regulator.
How do I proceed?
Regards,
MJ
