UPS for broadband router

[pendle]

Hello

We have quite a few power cuts where I live.  There have been 8 over the last 72 hours - since it started to rain again.

Sometimes they only last a few seconds, sometimes longer.

I'd like to get a small UPS for the router.  But two that I've tried, Eaton s3 and APC CP12036LI do not have adapters that work with BT router.  I got onto the BT help and the lady said that they are standard power adapters.  But the connected adapter and 4 others supplied just don't fit.

Is anyone else using a small UPS?  Can I get a recommendation?

thanks

If you're talking about the dc plug on the Smart Hub 2, it is an unusual size, 3.0mm x 5.5mm.  Most in this country are 2.1 or 2.5mm.  (You can use a metric drill bit, as a gauge, to check).

You can get the 3.0mm plugs but you will probably need to make up a cable of your own.  (Last time I saw the 3mm plugs on sale I think it was a US company called Phoenix.  Even if I can find it again, it is against forum rules to post a commecial link.  Sorry).

Edit:  Just checked.  It appears CPC Farnell in this country now supply them.

If you don't want to mess around making your own cables you'll either need the Cyberpower UPS that was/is supplied by BT, or a UPS with inbuilt inverter that provides 230V sockets to plug the router's AC adapter into.

If you go for the Cyberpower, make sure it's the right one. BT did one for the router & one for an ONT. Same device, just with different DC power leads.

Hello,

I wouldn't know how to put together my own cable, so I shall have a look at the other options.

thank you

I bought a Yuuki Power mini UPS, it comes with BT SH DC barrel connetors

I bought a mini UPS from Amazon by Yuuki Power to back up my BT Smart Hub 2. They provide a DC barrel connector for the BT Hub, which strangely, both the 5.5*3.0mm and 6.3*3.0mm connectors fit.

This seems to be a new brand, but it's still working and the product quality is good. It has a very clear screen and the voltage can be adjusted to 12V or 9V. Best of all, it has both USB-A and USB-C ports that support PD fast charging at 5V/3.6A.

Hi @Snow3   What is the Standby power consumption.  I have tried a couple of bigger units (not Yuuki) which had a ridiculous 18W and 12W burning electricity 24 hours a day.

You can always just keep them in reserve & charge occasionally, then connect when needed. Slight inconvenience in drop of service while you do versus the electricity saving.

Hi @Anonymous   That is exactly what I do on a timer plug.

@VeteranISPUser Have you ever run a BT SH2 though a power meter?  By default it's running at 9-12W, some of these BBUs can be pretty efficient!  Remember the good ole days when each light bulb was 60W!
