Which UPS

just get the biggest (kva) you can afford so the batteries don't get hammered. they're not designed to provide power for long periods, but rather just to give power for long enough to power things down. seeing you're just powering routers then it should be okay, and probably won't drain the batteries too much. those shitty batteries inside will die pretty quick if you run the ups until flat.

i cut the plug off a multiplug and fitted a female kettle cord plug to plug into ups. i think you can buy them already like that, not sure where.

edit: quick search:

Multi Plug 5x16A 5x5A 0.5m IEC Cord

Scoop's MP-10WIEC is a 10-way multi-plug that is made up of 5x16A 3-pin sockets, 4x 5A 2-pin sockets and 1x 5A 2-pin round socket.

Thanks Wingnut was thinking of this as an option, i guess battery will die over time but probably the most practical/affordable solution for me now. Thanks!
 
Yeah i checked that..was just worried about the amps? 0.6amp router and it says 1.5amp there. Dont know anything abt current, is that a problem or only thing i need to worry abt voltage? Tks for all the help!

yeah, dc-dc is better if you don't need ac. reasonable price too.

it means 1.5amp max, so anything less will be fine.

My Fibre router is 12v and WiFi TP-Link is 9v, my Eaton 2000VA gives around 2hours when only connected to the fibre router. I need the WiFi to last longer, is it worth getting one each of these? https://www.takealot.com/ups-12v-4800mah-battery-power-bank-for-wifi-fibre-lte-router/PLID54505552

Yes. But for much cheaper you could just use a regular 12V SLA battery (7Ah or so) with a small battery charger, replacing the original transformer... When the power is on, the charger will keep the battery topped up. When the power dies, the battery will just continue to power your router. A shortcut for doing this is to just tap into your existing UPS's 12 Volt battery, assuming it is a 12V and not 24V UPS. Just pop open the case and connect a lead with a suitable DC jack, directly to the battery terminals. The UPS charger will keep the battery charged, and when disconnected from AC mains, your router will still get 12V from the UPS, even if you power off the UPS. That will allow many more hours of use for your router which is what you are trying to accomplish. Obviously requires some electronics experience though so not for the faint of heart, but the point is if you already have a UPS then you already have everything you need to power 12V routers without needing to do a full 12V to mains inversion or purchase more separate equipment. I do it this way and am very pleased with the results
 
Rather get one of these. It has both 12v and 9v outputs at the same time.it runs my router and ont for about 7 hours.

What is the price for one of those babies?
 
I think a lot of people are getting the wrong idea. A UPS (Uninterruptible power supply) is something you use to keep things online for around 10-30 minutes while you shut down tasks, save files and keep things on without it crashing right away and shutting your systems down.

For a router, you could get away with using a UPS, but I see some people want to keep more things on for longer. Which is where I would recommend looking at an inverter solution. You don't have to start big, and it does get pricey but it will last you way longer than hammering a UPS for a few months.

Low wattage backups or time to turn off devices and save work = UPS
Mid -> High range power consumption for a longer period = Inveter

You could look at something like this: https://www.takealot.com/ups-12v-2400mah-battery-power-bank-for-wifi-fibre-lte-router/PLID54505551 but the picture itself makes me worry of its quality.

Edit: I am not against any of the recommendations posted above, just wanted to clarify if you want to run things for a longer time, with other devices an inverter will be much better.

How is this different in nature to the one posted above?

If you are talking about the UltraLAN Micro UPS, I would go with that. But its a little more complex to setup, but is really good if you need PoE ports with an injector, for cameras, switches and all of that fun stuff. Its 17.6 AH which isn't amazing, but for routers and networks

17.6 AH (which varies on battery, voltage, loss and such) but say a router is 12v x 17.5 AH = 210Wh (watt-hours).

Which means if your router is 15W and throw in 20% loss (so ~168Wh I only do this for safekeeping) then you will have around 168/15W = 11.5 Hours of battery time. But that quickly changes when some routers use 25/30 watts, an extra switch at 15w etc.. But it's well over enough for some routers and PoE equipment as most run at 15W.

For some quick router usage calculation. it would be 15W x 2h runtime = 30Wh storage needed.

Then why the caution saying we should rather buy the one you posted?

Think you are mistaking my poor grammar and sentence structure. I was warning people about using a UPS vs Inverter. Not about anything wrong with a UPS or the one that was listed.

Thanks for the reply, unfortunately electronics is not my area of expertise and looking for a plug a play option. I would probably look to sell the UPS, or keep it as a backup.
