For RV'ers the step-up - step-down booster buckers really are the best deal going.
Back in 1990 I found near the Phoenix airport a surplus dealer who had three beige steamer trunk size ferroresonant SOLA voltage adjusters. 270 lbs each. Out of the carton no instructions but all of the punch holes were in place. The surplus seller was adamant -- $400 each as is where is. Cash and carry.
Turns out they were top of the line +40% -40% line voltage correctors. I could only afford one. 168 volts going in? 120 out. 72 volts going in? 120 out.
But there's a glitch. Correction like this takes watts. 133 to be exact. 133 watts sitting there with 0.0 watts going out. 333 kWh over a 60 day billing cycle. And we are allowed 450 total in summer without going into excedente for another 150 hours then into DAC Data Alta Consumo which eventually reaches to above forty US cents US per kWh and applies to the entire CFE bill for months before automatically reverting to "normal".
I was crushed, the grand plan had a fatal flaw. For my in wall 5,000 BTU Gold Star I ended up with a Tor-Rey 2,000 watt unit just like described in this thread.
Need one in a strange city? Ask for the place that repairs refrigeration and well motors -- they'l have them in stock.
