How to power on my router

Technical Support for Routers

Dear community and team members,
Due to terrorist neighbor county, we have some problems with electricity, and have to use batteries. I have X750v2 and it helps me super great increasing 4G signal level (thanks to antennas).

I already bought Datouboss 2000W (this thing) but I doubt if original AC power adapter will be OK with such power source.

Or maybe better to buy something like this

With all respect,

I would say the power adapter will be perfectly fine with it. Since a few years it is allowed that the (European) power grid provides 230V ± 23V so 220V is totally OK.

OK, thanks! You helped a lot!

UPD: Tested. Working.

Can I connect it to UPS? It is a little bit inconvenient to manually plug and unplug it
Won't switching kill device?
