Hughes Autoformers 30 Amp RV Voltage Booster (Model RV 2130)

Protect your RV’s sensitive electronics and expensive appliances from low voltage. Unlike a standard surge protector, this patented Hughes Autoformer actively "boosts" low campground power to a safe operating level. When park power drops below 113-116V, the unit automatically provides a 10% boost to keep your AC, refrigerator, and microwave running efficiently. Includes a built-in grounding continuity test and diagnostics for open ground, open neutral, or reverse polarity. Easy-to-read LED indicator lights tell you exactly what the park power is doing and when the unit is actively boosting. Designed with no moving parts for long-lasting, quiet performance. Can be used portably at the campground pedestal or installed internally in a ventilated compartment with an optional kit.
