Helping finding DC UPS for Nokia ONT, Ubiquiti ER-X and Pi4B

Hi, I hope this is the right place to post.

Recently in my area there has been a spike of powercuts, none last for very long, few minutes max and its not overly a huge deal that the power is cut....mostly things just boot back up without issue but sometimes when the power comes back on it dies straight away again killing the ONT and Router half way through negotiation. I also have a Pi4B which is powered by USB-C which is a curve ball I guess to the normal DC UPS. I would like to keep all 3 powered but seems over kill to get a proper AC UPS.

The devices are:

Nokia-ONT G-010G (The white small one) - Power 12V 0.5A
Ubiquiti ER-X - Power 12V 0.5A
Pi4B - Power 5.1V 3A

Is there a small form factor UPS what would take care of these?

Thanks

This would do the job, Pi4B only needs 2A

Ahh nice, yeah thats the sort of thing I need. 2A should be fine for the Pi4B, its only my DNS server, its not going to be pulling more ever I doubt!

Found this to allow for easier use of multiples link

So I went for https://www.amazon.co.uk/dp/B0CNT6LLHP/ref=sspa_dk_h... in the end and its brilliant. Comes with 3 DC outlets and 1 USB, shipped you get one DC cable that splits into 2 which I have powered my ER-X and ONT off and I had my own USB-A to USB-C which happily powers my Raspberry Pi. I thought what the hell I got myself another male to male DC cable and hooked up my core switch also which is 12V 2A.

Pulled the power on it and after 2 hours had about 50% battery left, pretty chuffed!

Hi - I have wondered about using devices like this from Amazon.... most seem to be Far Eastern sellers delivering through Amazon Logistics - Do these devices have CE safety markings on them? Do you think they are safe to leave permanently plugged in / unattended?

Yep, I also wonder about the same sort of thing, to be honest though with the amount of cheap smart plugs, switches and bulbs in my house this device doesnt suddenly make me worry, as much as this has a large battery in it. Anyway I dug out the paperwork:

Of course I cannot tell you it will be safe, but I deem it to be safe myself and I'm really happy with it.

Thanks..

The question here is whether this is a "proper" CE mark or simply "Chinese Export"...

They *look* like proper CE marks to me, but it's worth noting that a great deal of imported electronics are marked with the proper CE mark design, but actually signify Chinese Export anyway.

Good point, but also I don’t know.

I’ll post back in a couple years let you know how I got on and if we had to move after some catastrophic event :/

I'm sure it'll be right. My internet connection runs through AliExpress's finest and, so far at least, I've had no issues with it and the house is yet to burn to the ground

Regarding UPS, I have to admit that I've got a normal Eaton AC output UPS for my kit, but this also runs a bit more than just my core kit, including router / proxmox, home assistant, CCTV, core switch and a few other small bits and pieces. Not all of this accepts a DC input, so my options were limited, but I get about 30 minutes runtime from a modestly-sized unit, so I'm happy enough. Not what you were after though!

I’m sure there are worse fire risks ins folks houses! I’m generally quite careful with it all aside from of course using Chinese stuff….

I looked at getting an AC UPS but my networking is so segregated it didn’t make sense, IE the internet stuff is in one area, there are switches in my attic for the UniFi AP’s and I sit actually at the back of the house, I’d need to power a lot of things in different places so I just stuck with the core stuff which is all DC.

I have a Jackery Mobile generator as well which if needed could power up my attic stuff which hooks back to the core switch, the back of the house would be down still but WIFI coverage would be there.
