Modified sine wave vs. Pure sine wave?
Reviewing the different modified sine wave inverter vs. the pure sine wave inverters they all have specs. that say suitable for small appliances, tv's, phones, laptops etc. Why is the " pure sine wave " inverter better and higher priced?

The current produced by modified sine wave inverters like this one is not considered to be as "clean" as the current from a pure sine wave inverter. While this modified sine wave inverter has low harmonic distortion and is suitable to operate most electrical devices, using a pure sine wave or true sine wave inverter is recommended for running especially sensitive products like laptops, TV's, etc. Pure sine wave inverters are more technologically advanced and therefore more expensive.
As the expert said: Pure sine wave inverters cost more because they are much more sophisticated than the Modified ones.
If your device has micro-processor technology, the modified inverter can and eventually will destroy your devices electronics.
Same would hold true for a common "Worksite" Generator vs an Inverter Generator.
Best to use something with less than "3" Total Harmonic Distortion. Generally your household wall current is 0-3 THD.
Modified Sine waves can be considerably above that.
I suggest that you Google a comparison.
