In the past I had been replacing old power strips with Tripp Lite Isobars similar to this one.

I don't usually have any issues with brown outs where I live, but my place of business has more issues with power outages and such. I have started looking into UPS power supplies instead of using the Isobars by Tripp Lite. I just want to make sure that my thought process is correct on this and if anyone can point out a flaw or something else that I need to consider.

I can across two UPS power supplies by TrippLite that look like they may fit the bill.

Tripp Lite 550VA UPS

Tripp Lite 600VA UPS

​

I have two computers at the front desk of my business that I would like to plug into the UPS power supply. To me it looks like the UPS is a better deal than the Isobar and I'm just trying to understand why as well. The UPS power supply appears to have a surge protector. There are also 5 plugs that provide battery backup. My thought was to plug the computers into the battery backup and plug other things like monitors into the surge only outlets. The 550VA UPS is basically the same price as the Isobar surge protector. The only downside I can see to using the UPS over the Isobar is that the batteries or the whole UPS will need to be replaced when the batteries die in a few years.

Any thoughts on this or words of wisdom?

Thanks!
