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.
For such a small load, you may consider those surge protectors/power stripes with battery backup, e.g. APC Back-UPS 600VA. Or you can take a more DIY route and try those DC UPS circuits if your low-power NAS supports direct DC input, i.e. it has a barrel jack for power.
isn’t that an UPS but in a different shape?
