I’ll believe what I have with my autoformer.
The legendary, original, and patented RV voltage booster, now with the world’s most advanced surge protection.
The all new Hughes Autoformer 30 amp power boosting autoformer (RV2130SP) has the same performance and reliability of the RV2130 but now has advanced surge protection built in! The unit offers 2,400 Joules of surge protection. As an added feature, the surge / spike protection module is also replaceable. In the event of a massive spike, the surge unit will take the hit ensuring your booster and more importantly, your RV is not damaged.
