I have a low power NAS (~35W) and I want to buy an UPS (uninterruptible power supply) to keep things running. The problem is most UPS for well known brands have an idle power usage (even without load) greater than 20W. It's comprable with the NAS + HDDs + Network equipment....

Do you know any alternative? UPS battery for 10 minutes will be enough. UPS load could be very low < 50 W. UPS software is optional.

There's the EATON 3SM36 UPS which does 36W on DC, but that is too close to your load. I'd have loved to use it as well, but it's just too light.

It would be a neat option if they have armed it with a larger battery. Even those dirt cheap portable battery packs come with 10Ah nowadays...

I guess it's enough to shit everything down safely. But with just 36W it's not really fit for anything but wifi routers and a Pi.

Edit: Well, I just gotta leave it now I guess😂

No, downwards, but very dangerously.

Runnin' a homelab on a Crapberry Pi!

The output is DC 9V/3A - 12V/3A - 15V/2,4A - 19V/1,89A. I will need extra adapters for other voltages like 5V.
