Router Battery Backup

Got to try out my GeeWiz mini UPS (1850 mAh version) the other day. This was feeding an Asus LTE router during a 1hr 45min power outage. It worked as advertised.

Great little UPS. Powers may router easily for the 2.5 hour loadshed.

I tried to UPS route. It's highly inefficient. converting the UPS 12V battery to 220V. Then plugging your router adapter in there to take it back down to 12V!.
I've solved the issue by simply powering my wifi router and Fibre router straight from 12V in the first place! The cheapest , most reliable option is to use a Alarm or CCTV backup system. They go for around R400 (Excl the R190 battery) and will provide power to your routers for roughly 6-7 hours!

Simply cut off the routers Power adapter power point off (or buy a new lead) and screw the two wires onto the product below. Voila that simple.

Here's a link to the product I'm referring to:

Here's another one:

Using the same, it is the most efficient and silent solution. ONT and a small Mikrotik are running on their own unit and they run for 12+ hours.
I also have another one with a buck converter installed to supply 5V for VOIP phones

hi iceman, that sounds good, but can you explain the connection part SLOWLY, step by step? i wouldnt want to cut off any existing wires in case i stuff something up, so what cord do i need? because both the mikro tik box and the fibre box both have their own power input points...
 
question - a lamp plugs into a wall socket, eskom goes down, no lights for the room, can you use the same cctv/alarm back up system to run a similar kind of thing as a lamp but we attach the globes and wire to the ceiling and then run it down to a plug point and then plug that plug point into the cctv/alarm backup system ?

hi, again, which battery to buy (automation africa in cape town) :
12v dc 1.3 amp battery R90
12v dc 7 A/H battery R195
24v dc 3.5 A/H battery R413

the one that gets the job done? to go with the cctv/alarm backup system to run the router and fibre box
thanks

Here's an article on the solution (with a video):

1) Either cut the power tips off from the adapter (of the wifi router) and connect the power tips with wires from the box
2) buy new power leads and connect them up (from brights or other hardware store)

This is the correct one if you're going with one of the 12V battery boxes:
"12v dc 7 A/H battery R195"

I have one of these and running Fibre router/CPE and Wifi router.
 
Can anyone confirm what the "standard" size plug is for these devices? I say standard because I know the Huawei b315, b618 and tp-link routers I've used are all the same plug. I think it might be 2.1mm, but if someone could confirm that'd be great.

i am looking for a cheaper solution just to run a mikro tik router and fibre box for the 2.5 hours that Eskom is having a power outage in cape town, i asked today at the shops for a cable that has usb to 5.5 power, got met with blank stares nothing like that exists-thought i could macgyver like youtube powerbank to the router, but maybe i will go to zakspeed to help with that....
all the computer shops suggested a ups but qualified it with saying its only meant to shut it down, not keep it going. one guy at another computer shop suggested buying mecer 650va ups which is currently out of stock, he said that will definitely work for a few hours. another one suggested getting an inverter trolley, nice suggestion if i got a few thousand rand lying around....
im not an electrician and a lot of the posts are just over my head, i just want a cheap solution that will work, i dont have thousands of rands to spend.
the mikrotik rating says dc10-28v and the other box where the fibre line plugs into says 12v-0.5A
hope someone can give a helpful solution, thanks in advance

When you say you want a cheaper solution what price do you have in mind? (or what price are you referring to?)
Not advisable to buy an inverter: They are expensive and inefficient.
If my unit (see pic as my logo on the left) is too expensive @R650 then:
Buy yourself a 7Ah battery (those used in house alarms & gate operators etc.) find a cable that plugs into your microtik router and connect it to the battery (+ve on the centre pin and -ve on the outer barrel)
That will keep your router going for hours..
(Just remember to charge the battery at some stage)

ok iceman, i will get the 12v7ah battery and the communica 12vdec on monday, plus a multimeter i will borrow, im not quite sure of the following :
the fibre box has its own power supply and the router has its own power supply, so i will need to have both connected to the powerbox I'm building, so how do you connect both at same time to the power box? what else do i need.
also confusing is the fact that the fibre box says 12v 0.5a but the mikrotik router box says dc10-28v (what does the last one mean? and is it still suitable for both these boxes to plug somehow at the same time into the powerbox im going to try and make)

You are spot on using quotations on "standard"
There are no standards but the 2.1 x 5.5 mm plug is the most popular I have found. However the voltage supplied by this plug can be 5, 6, 9 or 12 Volts..

The barrel plug has 2 contacts: The inner contact, normally a 2.1mm pin and the outer contact on the 5.5mm barrel.
The inner contact is positive (+) and the outer contact is negative (-)

Do you run your OTN and router of a single box, or does each device have its own?

Wondering what setup I would need to run my standard telkom OTN + Hauwai router

If I may respond to this question: No you don't have a PSU per decvice.
The backup unit provides power for all devices for that internet access (AP)

Thanks. All my devices are 12v. I happen to have a spare 12v 3A power supply lying around. I'm planning to hook up the 3 routers to this and then move the UPS to the TV. Not sure how long it'll last, but figure it's worth a try. I could always add a second battery to the UPS if necessary
