Hi! I'm new to the group and would appreciate some advice regarding using a mini UPS I just bought. My question is that my router has a voltage of 9V but the ONT has a voltage of 12V. Can I still use the mini UPS and what voltage do I set it to? Also, I see there is an option for 15V and 24V under "output" on the router so I am not sure which to select.

Thank you!
 
Details - we need more of it. What ups do you have? Model number? Pictures?

If your ONT is 12V and the router is 9V, then no, you cannot power both of them using the same DC plug. Does your mini ups not have more than one output? - ignore the 15/24V option, that sounds like POE output.

Edit:

Does it look like this?

Thanks for your message. It is this one below... The strange thing is it is powering both the router and ONT and wifi is working but I am worried about burning out the machine. 1656530825345.png
 
I connected the 9V router to the 9V output. That leaves 5V for the 12V ONT am I right? Eek this is confusing! At Computer Mania they told me it would work.

If we going that 5v is really 5v, then it wont work, but if your ONT is working, then I dont know.

This is the one I would have recommended to you, based on your requirements:

Mini UPS

Buy Mini UPS online at the Best Prices! Door to Door and Overnight Delivery. Voted the best online store in SA. View Here

It is the one I use as well, as I have a 9v router and 12v ONT, unfortunately, they dont have stock.

There is no way, that sales person knows what he is talking about. Technically you can only power one of your devices and not both.

Alternatively, keep it and buy a 12v only device, to power the ONT.

Fair but clutter. A non-lemon Gizzu will last years, even with bad load-shedding.

I would still return the Volkano based on shiitty advice alone.

@rh1 to be fair I am lucky to be on City of Cape Town power. So ‘sheds are limited to 2 - 2.25 hours.

In other cases, yes I would get a mini UPS for each device/ONT and router…

That salesperson needs a solid smack - he really should have checked with you what your devices require before selling you that particular unit especially since there are units that cost about the same and are designed to meet your need.

As others have said, your 9v device must be powered by a 9v output, and your 12v device by a 12v output.

What he should have sold you is one like this Gizzu 8800MAH Mini Dual DC UPS which has dual DC outputs each of which can be set to different output voltages.

Incredible Connection seems to have stock.

Hmm... Think the advice may be a little over cautious...

What's the exact device you are powering.

-- do not follow this advice unless you like taking risks ---
Most 5V, 9V, 12V devices have a PSU chip as the first thing and drop those inputs straight down to 3.3V... as such most of the time you don't need the voltage to be what you think...BUT if that PSU has a tight input it will blow up immediately...

Running the ONT at 5v (effectively undervolting) shouldn't damage it but it could cause instability.

That's not quite how voltage and amps work... But okay.

What's the exact ONT then maybe someone confident can say "Yeh, I run that at 5V and it's fine"
