Best small UPS for ONT & Router?

[ArcadiasWolf]

Webafrica sells a Netology Mini UPS 14400mah : https://www.webafrica.co.za/hardware/Netogy-UPS100/
Use it for my Openserve fibre ont and power hungry ASUS TUF AX5400 router and it lasted just shy of 6 hours.

Costs R1000, the same size from Gizzu is R300 more on Takealot.

Hi there,
Do you know what's the pin size needed for the dc output on this router?

Looks like 2.5mm to me
