Your paying way extra for power outage protection when looking at ups's which would be fine if your primary goal is to keep playing your pin when the power goes out.

If voltage drops are your concern why not just buy a voltage regulator for it?

There are many. Here is an example. Find one to fit your needs.

Spend that money on an adequately sized voltage regulator. That will solve the worry you started this thread about. What's the point of having and paying for a built in backup battery? Your pin isn't popping the breaker in the fuse box is it?

Also, ups's need their battery replaced as part of their maintenance cycle. This cost you more $$ every time you have to do that. UPS's and pinball - not an economically sound practice.

Kill a watt devices are not expensive. Every home owner should own one. That little device will tell you exactly what specifications to shop for with whatever solution you decide to go with.

Lol I get it. What you bought there can still be useful in an actual power outage, but on less demanding devices. Good luck.
