Router Battery Backup

Are you measuring the battery charging voltage with or without the battery connected? (Because a dud battery will pull that down to a lower value.)
Without the battery or any DC Load. Adding a DC load lowers the voltage that goes to the battery even further.
 
Hi Guys

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.

Any reason why this would not be a good option?

Thanks in Advance!
Should work fine except for the pi.
 
Hey guys, I need your advice.

I got 1 of these Gizzu 8800mah dual output ups for my sister.

She has a Tenda AC6/AC1200.

The mini UPS apparently only comes with 1 cord and it is short.

Where can I buy more cords and will her router need an adapter?

She has a Vumatel ONT. It apparently uses 12V

Thanks for your help
 
Given the product code GUP45W
Gizzu UPS is my guess
It's Ultralan - they just responded.

Anyone know the difference off hand?

EDIT: Ordered one - need to sort out this load shedding crap.

Anyone know how one of these lithium battery based devices will do in a roof? Thinking of using one to power my CCTV, but the stuff is in the roof. (temps seldom go above 45 degrees up there)
 
Running these bitches

Happy so far, but I might get this

Why would you put the stuff in the roof? High temps are not good for any electronics nevermind the cold swings in winter, but anyway, lithium has more tolerance to high temps than lead acid so it will probably be fine assuming the cold snaps don't go below zero, it will just shorten the lifespan I guess.

Just make sure your home insurance is up to date incase of fire :ROFL:

No choice, flat roof house, with minimal crawling space - so limited place to run cabling. There's a plug point in the roof that was used for the alarm, currently used for the PoE PSU - so would need to put this there.
 
I just got this one yesterday. How long does it last? Is it running a fibre ONT and router?
I got two seeing my ont is not close to the router and I'm not going to rewire/resetup that.

So one for the ont (+extra 12v dc 2amp power adapter for it) and one for the router. It's supposed to run at least 10 hours but I've only used 2 hours as per our loadshedding schedule.

Only con imho is the very short dc cable that comes with it. Otherwise I think it is good enough until I have done my inverter setup.

I think that a rechargeable battery in the roof is a very bad idea. Especially if it is always on trickle charge, like these ups units do.

Thanks for the feedback. Yes, the very short splitter cable is annoying. I've managed to get both plugged in by moving the router, but I'm going to get some DC extension cables so that I can arrange it nicely

I went with a bit of a happy medium (for me anyway)
Backup power at ground level in a spare plug,lead running up conduited to ceiling device
 
If I understand this correctly I would have to look at 2 of these units, as they seem to be limited to 2A output, my router is 12v at 1.5A and the ont is 12v at 1.2A.

Not sure which unit you are referring to, but they generally have the max output stated on the product datasheet.

Also, the power bricks for the devices you use will be over specced. I'd be surprised if those two combined use more than 1A.

Yes this is true my ONT and Asus Router only draws 0.86 amps when in use and that is also with both 2.4 and 5ghz wifi radios enabled so 2A will be more than enough :)
