I am about to install an Ooma device at the house and because we are always losing power, I need a battery backup.
They say this can be done, on their website - but don't say how, the online chat CSR insists it cannot be done.
The 120V power supply says 5V out. Seems pretty simple to me, anyone done it or have a suggestion on it?

I assume that you already have a battery backup for your cable/DSL/fiber modem and router? And a backup for any cordless phone that you might plug in to the Ooma device?

And then there is the cord-end compatibility issue.

The end that plugs into the wall gets plugged into a battery backup instead. Voila, backup power.

Battery backups consume power all the time, by the way, even if there's nothing plugged into them; so don't go backing up everything in the house unless you really love your power company and want them to thrive.

Yeah, just get a big enough UPS to drive the modem, switch and Ooma, if they are all co located (it wouldn't take much). How long do you need it to stay up for? APC and other major UPS MFGs have calculators on their site for figuring out how much time a certain load will get you and how much battery you need. Remember, if you have cell service, that could serve as a backup. I think with Ooma, you can log in online and forward your calls, during an outage.
 
If my power goes out, maintaining the Internet connection isn't my top concern. For that reason, I have a small generator which will power the refrigerator, freezer, and yes, the home network equipment. As long as I keep gasoline in the generator, I never have to worry about a backup battery being depleted.

If you experience frequent short-duration power outages which wouldn't require the use of a generator, a standard UPS would probably be the best solution. I'm sure that you could develop something custom, but without a transfer switch I would think you'd have to power the Ooma from the battery continuously, and then float-maintain the battery. Seems like a lot of effort for very little return versus using a small off-the-shelf UPS.
