What are you trying to protect from? A blackout is zero volts to a 120 volt appliance. Surges are thousands of volts to a 120 volt appliance.
UPS has only one function. To provide temporary and 'dirtiest' power during a blackout.
Now, view a 120 volt UPS output in battery backup mode. This one outputs 200 volt square waves with a spike of up to 270 volts between square waves. Power so 'dirty' as to be harmful to power strip protectors and small electric motors. But all electronics already contain superior protection. Therefore 'dirtiest' power from a UPS is perfectly ideal.
Surges are not zero volts. Protection already inside every appliance means protection from most trivial surges – above 120 volts. But a rare surge (maybe once every seven years) can overwhelm that protection. No plug-in protector or UPS claims such protection. Informed consumers read specs; not advertising.
You demonstrated 'zero' protection by not posting spec numbers (because those numbers do not exist). No power strip stops a rare and destructive surge. Protector circuits inside a UPS are even tinier. Just enough above zero so that advertising can hype it as 100% protection. Read so many posts. Advertising spin works. How do you know it is a lie? The claim comes with no numbers. Real world numbers say why a power strip or UPS does ineffective protection.
Learn the difference between a blackout and a surge. Completely different. One is no voltage. The other is voltage so massive that even three miles of sky cannot stop it. Why do you think any protector will stop what three miles of sky could not? Because you are listening to advertising rather than learning from science and damning questions.
The most difficult part is where one admits to being scammed. It’s not easy.
