I live in a location with power disruptions. So I would like to know whether there are any "mini" UPS available in the market that would either:

1) Give the plug a backup of 1 hour
2) Give at least 5-10 minutes so I get enough time to powerdown the plug software.

I have a hard disk inserted into Plug2 and due to these power outages am really concerned about the disk. I know I can use a normal UPS, but I am looking for something small, something that can be easily carried around like the plug. It would be odd to use a normal UPS as the Plug would then look like an ant in a football ground.

you may have found something suitable already, but... there seems to be some available, just try googling mini ups
