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?
Indeed they are 😂. It is especially true with the newer gen products. A few years ago these "power stripes with battery backup" had much smaller capacity and fewer capability.
Thank you for the link but I can't see the unloaded power consumption in the specifications.
I read about different UPS topologies and the model you suggested is "standby", the most power efficient => https://unifiedpowerusa.com/ups-topology-optimal-environment/
But some users report the "Cyberpower ValueUPS 600" (similar model) consumes - idle with nothing connected - 20W exactly
As far as I know the idle power varies from implementations to implementations, especially regarding charging. Also the idle power tends to grow when the battery ages (as the internal resistance increases).
If you are interested in the APC one, it does not hurt shooting them an email asking for the rated idle power usage. From my experience, APC has been pretty eager to respond.
