> I've seen UPSs blown by high draw hardware such as laser printers.
I've seen light bulb blow when powered on. That proves power cycling damaged light bulbs. I've seen the lake fill with water. The be filled with larva. That proves spontaneious reproduction. I've seen moldly bread breed maggots. That proves that maggots are spawned by moldy bread.
In every case, junk science. Because the conclusion comes only from observation.
Conclusions must come first from hard facts. A UPS is often made so cheaply as to be missing necessary functions including overcurrent protection. Other reasons could also explain that damage. But without knowing specifically what was damaged, then any conclusion from observation can only be wild speculation.
Bottom line fact remains. Power from a UPS in battery backup mode is often some of the 'dirtiest' power seen by an appliance. Due to superior protection already inside electronics, that 'dirtiest' power is sufficient or ideal. A need for "pure sine waves" to protect hardware is a popular myth.
Without knowing what was damaged or why, the observation is only speculation. Meanwhile, the observation does not change a reality. "Dirtiest' power from any UPS does not harm electronic hardware.
A UPS is temporary and 'dirty' power during a blackout. Blackouts do not danage electronics hardware. 'Dirty' UPS power does not do hardware damage. Other anomalies that can damage hardware require other solutions. But first that anomaly must be defined.
