Hughes Autoformers: The Best RV Voltage Boosters!

The ONLY Product on the Market to Offer Complete Protection from
Low Voltage & Power Surges!
Hughes RV Voltage Booster Replacement Surge Module!
This can easily be replaced in the event of a Destructive Power Surge!
VOLTAGE BOOSTING
As voltage drops, Hughes boosts to give you 10% more volts keeping your RV and its expensive appliances in safe / optimal operating range.
CIRCUIT MONITORING
Constantly Monitors the Park Circuit for Damaging Conditions. If Damaging Conditions are Detected, the Autoformer will Alert you of the Problem.
SURGE PROTECTION
Has the Most Advanced Surge/Spike Protection on the Market. The Surge unit is also replaceable so in the event of a damaging surge, the entire Autoformer won’t need to be replaced.
Introducing the Hughes Autoformers RV Voltage Booster, an iconic and patented solution that now incorporates the world’s most advanced surge protection technology. The 50 amp and 30 amp RV power-boosting Autoformers maintain the stellar performance and reliability of the original model, while seamlessly integrating advanced surge protection features.
This innovative unit not only boosts power but also provides continuous monitoring of incoming power, safeguarding your RV against potential spikes or surges. What sets it apart is the replaceable surge/spike protection module, ensuring your unit remains resilient in the face of unexpected power fluctuations. In the event of a massive spike, the surge unit takes the hit, effectively shielding both your booster and, most crucially, your RV from damage.
The Hughes Auto-former stands as the sole U.S. patented voltage-boosting solution available today, setting it apart from mere imitations. Its automatic functionality is noteworthy: when the voltage drops to 113 or below, the unit initiates a 10% boost, extending down to a minimum of 90 volts. Conversely, if the incoming voltage is at 114 V or higher, the boost is optimized at 2%, ensuring optimal performance tailored to varying voltage conditions. Trust in the unparalleled technology and reliability of Hughes Autoformers to safeguard your RV’s power needs.
WHY DOES LOW VOLTAGE OCCUR IN RV PARKS?
Parks Weren’t Designed for Modern High Demand RVs

HOW LOW VOLTAGE AFFECTS YOUR RV
OHMS LAW in Three Steps:
1. When Line Usage Increases, Voltage Drops
2. When Voltage Drops, More Amps are Drawn
3. When More Amps are Drawn, You’ll Experience:
• Dramatic Reduction in Air Flow
• Excessive motor heat (40% of all motor failures are due to overheating, even a 5-10% drop in voltage can exceed the motor’s full load or even service level amperage)
• Lights Dim
• Breakers popping or worse, pushing the amps just below the break point allowing the motors to excessively heat up thus putting the coach at a risk of fire
