Hi happy,
This is off topic.
The Sola Basic autoformer does raise voltage on the output side.
Since you refuse to open the link (and perhaps learn something) here are the figures for the first stage of boost.
Voltage with no load in the RV
Shore power input 114; output from Sola Basic inside RV 114
Voltage with air conditioner running
Shore power input 107; output from Sola Basic inside RV 117
All measurements were taking with a Kill-a-Watt meter.
Low voltage in Campgrounds is endemic when ever air conditioning is needed. Why? Because your beloved NEC allows 9 50 amp pedestals to be fed by one 200 amp circuit. It is even worse with 30 amp where 13 are allows on a 200 amp circuit. Further, over all, the campground only has to have 41% of the total capacity.
Now, do you have anything to contribute that is on topic?

Nec may forbid "hard wired" installation of devices, but since my autoformer unit is a plug in device it is not forbidden and is perfectly legal. There are many thousands of these in use in Mexico.
Mexico is not US. Besides, you can google some manufacturers who jumped into this bandwagon only to discontinue this product or went belly up because they cannot fool all the people. No one will stop you from using it or simply using it as foot rest which could be more useful than expect it to boost power.
There is no doubt this can be useful in Mexico because some rural areas there are feed by 240Vac. Having a center tap will enable you to use 120Vac appliances sold for US consumer.
I refuse to open the link you provided because I don't want to be suckered just like the rest.
