I have a 40 800 mAh powerbank that I would like to use to power my fibre ONT device as well as the router. From the battery's specs, it should be able to sustain both for at least two hours. The battery has a DC barrel jack connector (female) and two usb ports as output. I would need to power the ONT from the barrel jack.

The ONT device is a Calix GigaHub (from SADV) and it seems to be powered through a 8-pin connector. My question is how to connect this to the battery? Through a quick search online, I did not see any DC jack to 8-pin connectors. What are my options here? I would like to power my fibre without having to buy another UPS.

Thanks in advance :)

Edit: After further research it seems that the "8-pin" connector might be a EPS 12V (bottom left)

Wont work, because a powerbank delivers 5-9 Volts, you need 12.

Just buy an inverter.

Or use a big car battery with a 12V car socket attached like so:

The power bank I have delivers 12 V from DC barrel jack connector and 9V from USB. So it should work?

Oh ok, then yes, how many amps does it output, you need 1.5 at least.

you can then buy a Male and female barrel from your elecronic store with some wire and connect it up, boom, done.
 
It can output 10A.
So you suggest that I cut the original power connector and join with barrel connectors?
 
Sounds good, just measure the output voltage with a multimeter and make sure it is in fact 12 volts before plugging it into your ONT
 
Hi all! Thank you for the responses. I got all the components today and I’m certain I wired everything up correctly. However, I’ve run into some issues.
I measured the output of the 12V port but it was too low at first (11V). The battery was at 17% at the time so I thought charging it first would help.
Charging definitely helped but now the voltage is 12.45 V and as soon as I connect the ONT device it seems to short and the battery’s controller shuts off (along with power).

I have double and triple checked the connections and polarity. Also the ONT works just fine when connected to its original power supply (12.2 V output).

Any ideas what could be causing this? It almost seems like an over-draw but according to my information it could not be the issue.

Why the complicated connection just for 12V DC? It would seem thta there is more to the ONT to DC power brick than just a 12V supply which means it will not work IF it detects a non-standard OEM power source. Typical stupid thing on the part of SADV and its suppliers of ONT equipment!

Your only way out of this impass is an inverter feeding the original ONT power brick.

Isn't amps also important? Sounds like not enough amps?

Looks like the software may be monitoring the power supply? Perhaps check the software settings and see if there's an option to turn it off.

Thank you. What would you suggest in terms of an inverter? I am not really experienced with electronics.

It may be worth trying to get hold of an SADV techie and seeing if they can offer any suggestions.

Great suggestion. Although I'm not sure if they'd support me tampering with their equipment (which I'm technically just renting and do not own, as I understand)
 
Geoff.D said:
Could be. OP did not post what the Amp requirement was, just that his PSU could deliver 10A, which should mean that there would not be a problem as no way does an ONT draw more than 10A.
Click to expand...
Correct. The original power brink specifies 12V at 2.5 A. But it might be worth it just to check with a multi-meter.

Thanks for the info. Although it doesn't make sense to me that the battery would shut off and not the ONT? Also, how does one access the software of the ONT?
