Router Battery Backup

So I'm looking to power the following for at least 2 hours , preferably more for breathing room.
Asus Router + ONT18 W / 12 V / 1.5A
Access point12V 1A
Access point12V 1A
Raspberry Pi 4b5v 3amp 6.4w

The Raspberry Pi would be nice to have powered as well, but can be tricky to find a device for 5v and 3amp.

I've found these which seem to be suitable. Will get 2.

Mini DC UPS (12000mAh) Backup Battery Power Bank Supply (44.4Wh) - 12V Router, CCTV, Wifi Backup

Backup power for ANY 12V appliance Lasts approximately 5 HOURS on backup power Input:12V 2000mA Output:12V 2000mA

Any reason why this would not be a good option?

Thanks in Advance!

Been thinking on getting this for my router and ONT:
https://www.mecerpc.co.za/Mecer-DC-UPS-p-225542.php

From the looks of things it should provide power for 1-2 hours at 12V up to 2.1A. It's a plug and play solution without much DIY. Maybe it will work for you as well.

Could be a bit disappointing. I don't know how they're calculating their "backup time table" but it looks... ambitious.

2600 mAh * 3.7 V = 9.6 Wh. This is the theoretical energy available before conversion losses (worse at higher power), and battery aging. I think you could expect closer to 6 - 8 Wh.

A 12 V / 1.5 A router needs 18 W. This gives in the region of 20 - 30 mins.

The router power rating is itself a maximum, so you should do better than that on average.

But to get 120 mins it'll need to draw 3-5 W at most, which is really pushing it.

I have two of these. The battery inside is replaceable, but I tossed them as they were beyond dead. I then got a few 2600mah powerbanks and ripped the battery. Still need to test the runtime, but I doubt those estimated runtimes will hold up. It might keep an ONT running for that long.

Will see if I can do a test.
 
Oh look. Internet during load shedding... finally tested the two UPSes

Unrelated question, is there a comparison of Ubiquity APs? I see you can pick them up second hand everynow and then for R600+.

Looking for something that will work alongside my 2.4/5ghz LR APs - but specifically during load shedding. Not fused if its only 2.4ghz.

Why another AP and not just use the AC LRs?
I have two AC LR's and they are also running from my two UPSs (Gizzu type DC-DC UPSs)

and?
 
Finally had use for my Ratel 860P yesterday with power being out all day due to cable theft.

Got a solid 8 hours powering my FF ONT and Mikrotik hAP AC2, with the latter powered through one of the normal 12v outputs rather than the 24v POE.

Replacement battery was also degraded. Ordered two random 2000mah powerbanks. Should be able to pick up on Friday and test over the weekend.

@scienide
Pnp did not come through. Picked up an Amplify 2000mah powerbank from hifi corp for R49 today. After a lot of struggles I got it open and the 18650 battery inside was sitting at 2.4V. Busy charging it up inside the mini UPS.

Edit:
Battery was still charging this morning.

Edit 2:
Got home, unit was off. I assume the battery is charged up. Runtime test started. Battery voltage was about 4v.

Edit 3:
Runtime was just over an hour on 1 x 2000mah battery. Currently charging the battery again, for a second runtime test.

Edit 4:
Battery had a proper charge. 12v dlink router lasted just under 2 hours, with minor use/traffic. So my conclusion is that this unit will be enough to power an ONT-type of device that do draw a lot of power for about 1-2 hours, on a 2000mah battery.

Seems very similar to the Ratel units, and I think they even refer to it as a "Ratel" in the datasheet.
 
Hi guys. Yes its that load shedding time again and looking at getting a unit for the downtime. Not sure what exactly I am looking for but will list specs and devices below and possible solutions.
  • Huawei EchoLife hg8240h5 -- 12v 2.0A (Closest thing i found online was HG8240H not H5)
  • Tp Link -WR840N v6 -- 9V 0.6A
From my research I see this would work for me but not sure or if you recommend me an alternative it will be highly appreciated.

Picture of device looks wrong as there is another one with 12v *2 and this one 12v and 9v

Now my question if the above is correct. Can it run 2A on a device rated for only 0.6A and if not what can i do or get to make it work....

I have a 60w ultralan micro ups available if you're interested. PM me for details

Voltage is the crucial number as a device only draws the amperage it needs. As long as your supply is at least enough to cover the draw you can't have too many amps supplied.

Took delivery of the MU1008 unit today, so far so good will test by switching off the power supply within the the next few days.

The Ratel 430m should do the trick.

It's exactly the same, just with a different company logo on.
