The old Hughes Autoformers were great at one thing: helping protect your RV from low campground voltage. The new Watchdog Power Center goes much further - combining voltage boosting, surge protection, app monitoring, fault alerts, remote power control, and a replaceable surge module in one system.
The old units focused on low voltage. The new Power Center adds surge protection, app visibility, fault history, power control, and better overall protection.
RVers who camp in older parks, deal with inconsistent pedestal power, or want a better all-in-one setup than a basic booster alone.
This is not just a refreshed autoformer. It is a full RV power protection system built for how RVers actually camp now.
The older Hughes voltage boosters earned their reputation because low campground voltage is a real, persistent problem. RV parks were built for a very different era of camping. Today's modern rigs run massive rooftop AC units, residential refrigerators, induction cooktops, and racks of electronics - drawing far more current than aging infrastructure was designed to handle.
When voltage sags, think every rig in the park cranking AC on a hot afternoon - Ohm's Law kicks in: as voltage drops, amperage draw increases, motors run hotter, and breakers pop. Even a 5 - 10% voltage drop can push an AC compressor past its rated service amperage, quietly shortening its life over time. The original Hughes Autoformers addressed that problem well.
But campground power problems are not just about low voltage anymore. Surges, wiring faults, open grounds, and reverse polarity can all do serious damage, and the old booster had no answer for any of them. That is where the Power Center changes the game.
The old booster was a one-trick pony, and it was a very good trick. But the Watchdog Power Center does the work of what used to require two separate units (an autoformer and a standalone Watchdog surge protector), packaged together for less than you would pay buying them separately.
The patented ~10% voltage boost still kicks in when park voltage sags below ~113V, but now advanced surge/spike protection is built into the same unit. You are no longer just correcting weak voltage.
If a damaging surge hits, only the surge module takes the damage, not the whole unit. Swap in a new module for around $55, and you are back in business, instead of replacing the entire device.
An LCD display shows both what the campground pedestal is delivering and what your RV is actually receiving after boosting, so you can stop guessing and start knowing.
No extra hardware required. Monitor voltage, amps, watts, and fault alerts from anywhere using the free Power Watchdog app. Turn power on or off remotely from your phone.
When a serious fault is detected, power cuts instantly to protect your coach. Once conditions clear and remain stable for 90 seconds, power restores automatically, no manual reset needed.
A full fault log shows what happened and when, useful for diagnosing recurring issues. The energy meter tracks kilowatt-hours, handy at campgrounds that charge per kWh.
"We have accepted that we need to protect our RVs from high voltage surges, but most of us don't think about the damaging effects of low voltage."
If you already own an older Hughes Autoformer that is working fine, you don't necessarily need to replace it today; the core voltage-boosting is unchanged. But if you are buying new, or running a booster without surge protection, the Power Center is the clear choice.
This part is simple. Match the unit to your RV's shore power service. Both models offer the exact same feature set — voltage boosting, built-in surge protection, WiFi and Bluetooth, EPO with auto restore, fault history, and energy metering. The only difference is the amperage rating.
For 30-amp RVs, travel trailers, and fifth wheels that want complete low voltage and surge protection in one unit.
For 50-amp motorhomes and fifth wheels that want a smarter, more complete solution than an older booster alone.
No. The low voltage boosting is still there and works the same way, but the Power Center adds built-in surge protection, smarter monitoring, app access, fault tracking, remote power control, and a replaceable surge module. It combines what used to be two separate products into one.
No, for most buyers, that is the whole point of the upgrade. The Power Center is designed to replace both the old autoformer and a standalone surge protector in a single, more capable unit.
You can see exactly what power conditions look like at the pedestal, what your RV is receiving after boosting, current draw, and any fault alerts, without walking outside or leaving your chair. Remote on/off control means you can manage your rig's power from the camp store, a restaurant, or anywhere with a cell signal.
Only the replaceable surge module is damaged, not the entire unit. You can swap in a new module for around $55 and be back up and running, rather than replacing the whole device.
No device turns terrible campground wiring into perfect utility power. What the Power Center does is give your RV a much stronger layer of protection, cut power instantly when dangerous conditions are detected, and restore it automatically once things stabilize, all while keeping you informed through the app.
Hughes Autoformers has been the name in RV voltage protection for over 20 years, and the Watchdog Power Center is the most significant evolution of that technology yet. By combining proven autoformer voltage boosting with the advanced monitoring and surge protection of the Power Watchdog line into a single unit, they have created a product that genuinely does it all.
Whether you are a weekend warrior or a full-timer logging thousands of miles a year, this is the kind of investment that pays for itself the first time it saves an AC compressor from a low-voltage campsite, or cuts power before a bad surge reaches your electronics.
Both models are available now at RV Upgrade Store. If you have questions about which unit fits your rig, reach out and we are happy to help.
If you want more than just a basic voltage booster, the Hughes Watchdog Power Center is the smarter move. Pick the model that matches your RV and get a cleaner, more complete protection setup.
