So I moved into a new house but discovered that the previous owners have taken the power supply cable for the ONT. So I can't get internet . I contacted skinny and they gave me the chorus link https://www.chorus.co.nz/contact/ont-replacement to get a new cable sent to me as it appears this is very common thing to happen. It is the model 300. Don't know why they don't have them wired in to prevent this happening.

However while waiting for the cable which could be a week, I do already have another old Spark modem cable which is 12 V , 2.0 A, for one of the large white spark Fibre modems which is about 2-3 years old Huawei HG659b , and it appears the ONT is 12 V 1.5A according to the instructions. Anyone know if that can be used. It appears to fit in the hole.

If it is a Huawei psu, at least one place is selling them as ONT 300 compatible. https://www.mobilestation.co.nz/huawei-switching-power-adaptor-hw-120200a6w.html

A power supply needs its Amps to be equal or higher than the device that will draw current,

The device will only pull what it needs,

BUT

You need to make sure the Voltage and centre pin polarity are equal on both the Device and power supply,

-Also the plug needs to fit the socket

Looks like you should be fine. Voltage is the same and 2.0A is higher than the 1.5A required.

I had the same issue with a missing power adapter for the ONT when I moved house a few years back. Used one from an old router which had suitable voltage/current until tech came to replace it (over a week later!) Funny thing was, he told me he couldn't just replace the missing power adapter, he had to replace the whole ONT!!! (This was on Northpower Fibre) Apparently something to do with them only being supplied together!?!? He thought it was stupid as well.

Thanks I thought so based on the specs of the ONT. I just wanted sure if the centre pin is positive or not. I think they are normally centre positive. Spark modem transformer doesn't actually show what the centre pin is

Thanks. Hoarding old modems does sometimes have its benefits

I can confirm the model 300 ONT's PSU is centre positive. See below. So are the Huawei PSUs for many of their modems/routers including the B315s, B618, HG630b, HG659 and HG659b.
