The legendary, original, and patented RV voltage booster, now with the world’s most advanced surge protection.
The Hughes Autoformers 50 amp RV power boosting Autoformer (RV220-50-SP) has the same performance and reliability of the original RV220-50, now with advanced surge protection built in! The unit offers 4,800 Joules of surge protection and constantly monitors incoming power to protect against spikes or surges. As an extra 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.
The Hughes Autoformer is the only U.S. patented voltage boosting solution available today. All others are imitations.
The unit will automatically start boosting 10% if the voltage drops to 113 or below. If the incoming voltage is 115 V or higher, you will have only a 2% boost.

Not OEM material, doesn’t slide as easily. Feels like it will last longer.
Color: Grey, Color: Grey
Thought it was going to be the same quality as OEM, might last longer but definitely has a different texture.
Fits well.

Very happy
Color: Grey, Color: Grey
This is a 3d printed part. It fits great, looks excellent, works fantastic. I bought the grey version.
Work the part in carefully, take your time. The seller’s video in the description is very helpful! Great alternative to dropping $100 on a replacement. Excellent value, fast response and shipping..

Works for E46 M3
Color: Black
Great customer support, fits like it should, is a nice detail that you’ll notice if yours is broken. Looks like OE. This is my first 3D printed part, I hope it’ll last another 20 years. Has lasted almost a year so far!

Off - color
Color: Black, Color: Black
Flimsy, pretty obviously 3D printed. It's noticeably blue in color, but no one in the front seats will notice.
This is good as an aesthetic bandage fix, but I'll go back to sourcing an OEM piece.

Poor quality.
Color: Grey
This is a waste of money. No communication from seller. It took super long to receive it and when I got it , it was a big disappointment. This is a junk.
