so it depends what its protecting and if you think a surge might damage said device, but PSUs are pretty good at filtering the crap imo.I know belkin are decent, but i prefer something with single row and more sockets
. I set it to safely shutdown after 10 mins. This is an entry level UPS I'm sure but it has USB connection and the battery is replaceable, sorted (and recommended). I might run a cable over to my PC as well (NAS in the kitchen to remove HDD noise from PC), obviously the 2 hours battery backup would drop to about 4 mins if I did that.
