They are advertising a power inverter for running AC pumps from a PSU. From the specs:
"Modified sinewave output voltage"
Typically this statement means an output like the signal shown below in red.
A modified sinewave like this is fine for a lot of electronic items, but it is likely to make a pump run very hot, and may well result in the premature death of any pump it is used with.

While the modify sine wave looks “bad” it really isn’t. That modified sine wave in some cases is better then what comes out of the wall in some parts of the country. I am not defending DD advertising just pointing out some facts.
