Router Battery Backup

Anyone tried to do a DIY power backup for their router using a powerbank with quick charge (12v)? Looks doable:
looks like those triggers are sold on Bid or buy...

Really? They're surprisingly expensive at Banggood. May look into that (but not for my Internet backups. My back-of-the-envelope calcs say I need to use Lead Acid rather)
Also the actual QC powerbank is quite pricey too. Works out cheaper to buy a Lead Acid unless you already have a QC powerbank

What does the trigger do exactly?
 
Did see that, post doesn't explain its actual functionings, just that it can be used with a power bank for 12v devices, and didn't have the time to watch the video. Will do so when I have some time

I just found this on youtube,


Its a nice small PCB design,

I want exact same concept but be able to pull more amps, with 5v and 12v outputs, (ONT, Mikrotik Router, Raspberry pi4, and one or two POE devices)

A bit late but - it tells the powerbank that you have a "Quick charge" compliant phone plugged in and that it can output at a higher voltage and current. Otherwise it'll just keep pumping out 5V.
 
Omnipower Ratel 430m feedback :

Purchased it to power a 12V fibre Vumatel CPE/ONT and 9V router.

Since having installed it, loadshedding has not been scheduled yet, so I decided to test it by just switching off the plug.

It ran for 3 hours and only went down to 50% on the display of the unit.

Very happy!

Do you have any idea as to the wattage of those devices? As a broad estimate, what is the amp rating of their power supplies?

The 430 range can deliver a maximum of 30W over all the ports. The ports are typically 2A max each.
 
I have a 10 Mbps ADSL line and up until January 2020 load shedding I relied on my Mercer Inverter to power my tv, per and router. However, now my phone line goes dead as the exchange’s have stopped power backup. Well, at least mine in PE has. I’m on a 367 # and fed from Adams Road exchange via on of those metal boxes outside Walmer Park Mall. Anybody else having the same experience?

What is the wattage on that, about 20w?

By those rough numbers @joshuatree ran about 15w for three hours, so 45wh, for 50%.

The specs are for 4*2200mah batteries but doesn't say anything about their voltage. 4*2200mah at 12V is 105Wh, which roughly agrees with 45Wh being 50%.

I haven't measured it with a multimeter. The supplied power supply is 12V 2A. I searched for its specs and some documents said 20W and one 12W. I'm more inclined to be believe the lower.

Assuming the battery ratings are indeed at 12V, the batteries should give 105.6wh. Using 25% (26.4wh) in 2:15 would be 11.7w.
