If you’re an RV owner dealing with annoying 12V power fluctuations, you already know how frustrating it can be. Lights dimming, fans slowing, or electronics acting up—it’s all a sign that your converter might be on its last leg. I recently went through this with my rig, and after doing some digging (and almost getting burned), I want to share a quick but important warning: watch out for fake WF-9855 converters.
What’s the WFCO WF-9855?
The WFCO WF-9855 is a 55-amp power converter designed to supply reliable 12V DC power to your RV’s systems while keeping your battery charged. It’s a workhorse—well-built, dependable, and the kind of component you want behind the scenes, especially if you’re on the road often.

Beware of Cheap Imitations
While shopping, I noticed listings for what looked like the same converter—same model number, same description—but selling for under $100. It seemed like a great deal at first… until I looked closer.
Some of these cheaper listings aren’t actually made by WFCO at all. They’re knock-offs using the same model number, but the build quality is completely different. These units often use subpar components, can run hotter, and in some cases, fail right out of the box—or worse, damage your RV’s electrical system.
Red Flags to Watch For
- Prices that seem too good to be true (under $100 is usually a warning sign)
- No mention of WFCO as the actual manufacturer in the listing or box
- No warranty or unclear return policies
- Generic packaging without WFCO branding
Why I Went With the Real Deal
When it comes to RV power, reliability isn’t optional. After reading horror stories in RV forums and reviews, I knew I had to go with the genuine product—even if it cost a little more. The peace of mind alone is worth it.
The authentic WFCO WF-9855 has:
- Quiet operation
- Three-stage charging for battery health
- Built-in protection features
- A solid reputation in the RV community
And best of all—no more power fluctuations.
Final Thoughts
Don’t cut corners on critical RV components. If you’re seeing the same model number listed across several sellers at wildly different prices, that’s a red flag. Make sure you’re getting the real WFCO product—not a risky imitation.
If you’re in the market, this is the unit I trust and installed in my own rig:
