Alternative Power Source for Router

[Lazy Sod]

My EE router is powered by a plug in charger that has an output of 15v at 1.2 amps. If we have a power cut in the daytime that we know will last some time, I will fire up my generator.

However, it occurred to me that just for short periods, I might be able to run the router from a battery that I have. It's a 12v. sealed AGM 17ah battery that I bought, probably 10 years ago, to go on an old ride on mower that I had at the time. When I scrapped the mower, I kept the battery as it wasn't very old. Over the years, I've kept it charged up and it keeps it's charge for long periods. It's been a useful as a 12v. source on the workshop bench etc.

I've got a charger plug from an old router that has the same plug on the end of the wire, so it fits my current router. I have cut the old charger plug off and fitted a couple of crocodile clips. Presumably my router only draws the current that it wants, so carrying out my plan to use my battery won't hurt it. Similarly, if I used my TopDon 2000 jump pack, would that fry the router?

Would not be better to buy an Uninteruptable power supply for the router? They aren't expensive and also have overload protection too. New tech seems very easy to overload these days.

Something like this:

APC Back-UPS 650VA - 230V - 8 x AC Power - 1 USB Charging Port

Would probably run a router for a couple of hours.

Although let me know if that works as I have one of those batteries in the shed too!

I want to try it, I just want to ensure that I'll do no harm to the router.

A fully charged AGM battery probably puts out about 13.8v , the router might work at that...
I doubt it would harm it if it was undervolted, however, it might not work reliably.

Draytek routers generally work from 12 - 15 volts, so they could be powered direct off the battery.
Failing that then APC s are normally used for this type of thing.
