Router Battery Backup

I received the Elecstor 100w mini UPS today and I am really impressed!

75Wh for R1299 is good value. It has multiple outlets of different voltages and also came with several cables and adapters.

I like the look of it too, like a little decoder :)
It also shows how many Watts you're drawing at any given time. My setup uses between 12W to 13W, meaning I should get over 6 hours without breaking a sweat. After tonight's two hour load shedding, the battery indicator light was still on full

I'm very chuffed and would highly recommend it to anyone else.

Only downside I can think of is there is no POE but that wasn't a requirement for me
 
Which is the best of the cheapie mini UPSs nowadays? Loads of them under R400 on Takealot. Just need something to power a Huawei B535 for a few hours.

I have 3 of these. Very happy with them.
One for my fibre modem, one for my Mikrotik WiFi router and one for some some Sonoff modules (my gate used to open randomly when mains returned after load shedding)
 
May do this for the extra 3200mAh.

I would personally be slightly suspicious of the "12000mah" description on Takealot, there are are some 8800mah units that have been incorrectly described as 12000mah on there. Sometimes one sees reviews there where people have opened them to find the same 4*2200mah cells as on all the 8800mah units. There are loads of identical 8800mah units like that, all from the same base model but sometimes with different branding or an extra cable or something, but generally they are the same model one can order in bulk from China.

It looks like even the newer 530p model will still have 4*2200mah li-ion cells:

The thing about the 8800mah/32wh units is they are cheap and will give you a good period of service before declining too much, even if they are not LFP - I had one on my router a couple of years ago before replacing with a Gizzu 69wh LFP unit which has been excellent. But I still have that old 430p ups as a power supply for a 12v emergency light so it's still in use in some way and for the price they will do the job for a while.

Invaluable advice. Thank you!
 

Veeeerrrry expensive for what it does

Gizzu is much better, even has 24/48v PoE

Thanks will get that after a year when I need to inevitably replace this one again.

But if you don’t need 24/48v Poe that’s only 46Wh vs 57Wh of the Vizia, which in my books makes it better value?

Got this one in July from Takealot was R899 on a special. Have 2 routers totalling 48 watts running from it and also use it to charge the usb lights and lamps. Just keeps on running and lasts for at least 6 hours without power and the batteries show no signs of degrading yet. So no complaints yet.
 
Purchased two "knock-off" Ultralans in Nov '21 and both have powered my Huawei B618 for 4-hour loadshedding slots with spare capacity left.

Both are still in use, but the usable capacity are somewhat diminished.
One powers ONT + Huawei router, but doesn't last for 2 hours, while the other one easily powers a ZTE LTE router for 2 hours+

Your Ultralan is probably from a bad batch.

Edit: Payed R998 for both and they're cheaper than ever on Takealot now.

Had mine since the end of '22. Using it to power my USB fan now and it'll last even a 4h LS stint so it's still getting used.
 
Need some advice please.

Recently received a faulty unit that "popped" while driving an ONT+router.
Batteries are shot too, although I could salvage one.

Upon opening I discovered two blown caps, 16V1000uF which I'll replace with 25V ones.

It's a 10000mAh, but can't confirm as the cells do not have any markings on.

Now, I want to replace those with 3000+ ones.

The question is, will the BMS (built-in to cct board) be able to handle the larger capacity?

They're connected in a 2S2P config.
