Re: Cable Modems

[John Jones <chianime@xxxxxxxxx>]

I'd estimate between 5 & 20 watts for each device:
- Cable modem
- Standard router
And common add-ons:
- VOIP adapter
- Additional small switch

A modest UPS should provide 45 minutes or more of continuous run time.

That said, if your UPS battery is more than a couple of years old it
probably won't provide the same run time as it did when new.  Like most
batteries they do degrade over time.
