I noticed that 110v VFD's are now widely available in 1.5kw, 2.2kw, 3kw and 4kw. Being able to use any 110v outlet would be way more convenient than being limited to the one 220v outlet in my workspace but are there any issues I should be aware of with them?

Is anyone here using one? If so, how do they perform vs the 220v equipment?
