Powering Asus 68u via DC not AC and barrel plug size

I am looking to power an Asus 68u via DC and not AC power. I plan to use a step up transformer to go from 12V DC to 19V DC. The problem is now figuring out how to go from that to the router. I am trying to find the correct barrel plug size and where I might obtain?

I have read in some places that it is 4mm x 1.35mm? Does anyone know if that is accurate?

Has anyone else powered their Asus 68u (or similar) with DC power versus AC power?

Thank you

Tip size: 4.0mm x 1.35mm
Outer: 4.0mm
Inner: 1.35mm

Other options:
1. Buying genuine ASUS Laptop adapter.
1.75A or higher(high is better)
33w or higher(high is better)

2. Buying a compatible adapter with tip sets.
1.75A or higher(high is better)
33w or higher(high is better)

awesome find on amazon! i was looking for a couple hours last night and found maybe one option on ebay that would take 1-2 months to arrive. i was debating just cutting the ac adapter lead and using that but thank you for finding an alternatve! as for watts, input says 19v / 1.75amps so as long as i have 19v and 1.75 amps i should be fine, right? no need to worry about watts? i was looking at a 12v step up to 19v 3 amp transformer so that exceeds 1.75 amps... thanks again!

A step up transformer converts AC to AC, not DC to DC.

One year later, I finally implemented.

I got an Uxcell 12v to 19v converter on Amazon along with the barrel adapter listed above and https://www.amazon.com/gp/product/B081Z8WRK5/?tag=snbforums-20

I am also using a Y 2x USB to 1x micro USB in the USB ports of the AC68u that is powering a Raspberry Pi 3 B+ running pi-hole

We will see how stable everything is but now I dont need to worry about switching on the inverter to maintain power to the AC68u when AC power is not available. I was also concerned about interrupting power to the AC68u and corrupting the Raspberry Pi SD card as some times AC power is not stable, when it is available.
