Often times low voltage isn't limited to just one site. If a campground has expanded too much over the years... and didn't upgrade their grid while doing so... voltage drops under high demand.
The voltage booster resolves that problem.
The booster (transformer) will draw a little current on its own in order to step up the voltage, however that current draw is less than the current draw of your appliances/ac-units caused by under voltage.
