Router Battery Backup

Imraank said:
Inspired by this thread, I decided to make my own redneck router backup battery yesterday. Gave me around 2 hours of usage before the lights came back on, so I'm chalking it up as a success.

Parts: 3 X 18650's, 2 X binder clips, 2 X old hard drive magnets, some wire, and a barrel connector.

Hello Imraan (from a fellow UKZNer)
 
Bugger, my order was cancelled. Oh well, will wait for Communica, their delivery is cheaper anyway.
 
I'm having buyer's remorse over that Gizzu UPS now. That Ratel is looking mighty tempting, especially with the 5VDC output that means I can power a Pi as well. Dammit!

Can you post a pic of that modified power cable? Mine is slipping out as well.

At work right now so unfortunately I can't post up a pic.

I saw that the two 'prongs' on the UPS side are larger than the receptacles on the cable side. So it doesn't fit in all the way. So what I did was take the sharp end of a multimeter test lead and widened the copper contacts on the figure-eight cable and then jammed it in good. I hope this makes sense!
 
Settled on a Ratel 430P since the 860P is only in stock again end of January. Still matches my requirement (LTE router and an IP camera) and is R600 cheaper. R912 incl delivery. Don't really need the solar charging and 4 extra 12V ports on the 860P, though it would have been nice to have. I seriously considered getting two 430Ps or a combination of a 430P and another model.

The decision I suppose is determined by how many devices are colocated in the same or close enough to each other to be fed from one point. Splitting into 2 x units instead of one increases flexibility, so that would be in my opinion also a valid decision criteria.

PoE ads distance.

So a mini-review of the Gizzu 8800mAH UPS that I ordered from Raru on Sunday:

UPDATE: Powering the Edgerouter X (24V PoE Passthrough), Huawei B315 (12V) and Unifi AP AC LR (24V PoE) the battery level dropped to around 75% after exactly two hours of load shedding. Recharge time was about an hour. I do have the worry that should the unit lose power altogether by discharging the batteries, it won't turn back on by itself when the power returns as the ON/OFF switch is not a toggle button. I'll try and play around with it this weekend and see if I can discharge it completely and then give it power again and see if it only resumes charging of the batteries or if it will start outputting power immediately.

The unit feels solidly built and seems to be well put together. There is a sticker on the back that designates it as a POE-45P unit. If you search for this model, you can find it for sale on Alibaba and other wholesale sites. I did find a picture of the unit disassembled and it seems to have 4x 18650 batteries of 2200mAH (claimed) each. The unit has ventilation grilles but no fan; everything is silent.

There are 4 green LEDs denoting the SoC (State of Charge), from 25% up to 100% in 25% increments. The unit was 75% charged when I received it, and I topped it up to 100% using the supplied figure-of-eight connector. This took around twenty minutes, but I do not know how discharged it was upon receipt of it. The lights pulse on and off 'softly' and looks quite sleek as opposed to them just blinking on and off. One could say the lights are 'breathing'. The connector would not fit and had a poor mate with the unit, so I widened the copper contacts on the power lead with a ballpoint pen. It provided a better fit after the slight modification.

The unit comes with a DC cable that is split at one end, so you can power two devices simultaneously provided they are the same voltage. There are two switches on the unit to select voltages (5/9/12V for the DC jack and 15/19/24V for the PoE jack) and indicator lights telling you which voltage is selected when the unit is turned on. It doesn't appear as if you are able to power one or the other; both outputs are active at any given time.

There are four rubber feet on the bottom of the unit, and two holes that you can use to mount it against a wall using some screws. Beneath the rubber feet there are Philips head screws, presumably to open up the unit for servicing.

I will be powering an Edgerouter X and a Ubiquiti Unifi AP LR using the PoE output, as well as my Huawei B315 LTE router. The max current draw for the devices are 5W for the Edgerouter, 7W for the AP and 5W for the B315. I expect about a 6 hour runtime before the UPS turns itself off, and I will try and record the runtime as well as the time to recharge whilst still powering the equipment up. I also discovered that the PoE ports are 100Mbps capable, and not 1Gbps as is with my previous Ubiquiti branded unit. This isn't a train smash for me, however, as I just feed my B315 into it which will never see 50Mbps let alone 100Mbps (the screenshot says PoE not supported because that port [eth0] is used as passthrough and all they mean is that it cannot output PoE through that port):

Hi

I have an Asus ac68u which runs at 19v. Would it work with this mini ups? Any way to get it to run off the poe?

Unfortunately I've got 3 devices, ONT, Grandstream ATA and the Asus router. All run at different voltages.
One 5v , one 12v, one 19v. And ideas what to use?
 
Which Model Ratel from Communica best suits my requirements for my Nokia ONT
and Ubiquiti AMPLIFI HD Router.

I’m basically looking for a plug and play backup power source

Note, the Ubiquiti uses a USB C port for power on the Router 9V 1.7A

I would have preferred the 860P due to double the battery but it's out of stock until end of January. I got the 430P as I want the DC and PoE output.
