I use this. It has 2 outputs if you need to power something else that's the same voltage. I got the premium version for the extra couple bucks.
Which External Linear PSU Upgrade for my Router?
I'd like to upgrade the wall wart PSU on my Netgear Nighthawk RAX50v2 router to a linear PSU.
The output is 12v, 2.5A 30W
I'm looking at a LHY Audio one - https://www.aliexpress.com/item/1005005350110413.html
But i'd like to know what else is out there. Would appreciate your thoughts.
