Stupid question about electricity

They are both called UPSes - therefore they do same? Word association being used to invent a fact. An industrial UPS located at the service entrance is confused with something completely different - a $100 box that does nothing but a few minutes of backup power. It does nothing more - does not do all those things aimeecc posted. A serious UPS performs a long list of functions for thousands of dollars. Therefore the UPS for tens of dollars also does same? Nonsense.

$100 manufacturers quietly say don't put motorized appliances on their products. They say to not do what aimeecc recommended.

HungLikeJesus, show me where it claims to protect from spikes or improves power quality. Do you believe the manufacturer makes that claim? Show me. Intentionally said bluntly because no such claim exists.

What does a UPS do? Connects an appliance directly to AC mains - no filter, no spike protector, no harmonic attenuation, no voltage adjustment. When power goes off, that UPS provides no power while taking time to switch to batteries. Then it outputs motor harmful electricity.

Those building wide systems installed in communication facilities don't do any of this; perform differently. Even their batteries have a 20 year life expectancy.

Same logic that proved Saddam had WMDs is also being used here to wildly speculate what a UPS does. When I say ‘learn lessons from history’, I am citing the same failed thinking (wild speculation) that makes these above UPS claims. UPS manufacturer does not claim what was posted for the same reasons that no facts said Saddam had WMDs.

Well, HungLikeJesus and aimeecc both have posted what the majority believe. Majority does not make a technical fact. Reality: those popular beliefs about UPSes are completely wrong; promoted by people with George Jr ethics (except that UPS promoters don't claim to talk to god).

HungLikeJesus - did I make it obvious how adament I am about those UPS lies? You and aimeecc should go after those who lied to you about UPSes. Those liars should have zero credibility.
