Good product
This product appears to be working well after the install. The install itself is very simple and straight forward. This product is completely RF quiet, which was important to me since I operate sensitive radios for long distance communication in the RV. This is the second WFCO product I have used. The previous one started giving signs of failure after about 5 years on the job operating on a daily basis 24/7. The first one was still working but started making a loud hissing noise. That was a sign that it was time to put it out to pasture and avoid a complete failure at the least opportune time. If this one lasts another 5 years, I'll feel like I got my money's worth...again.

RV battery was not charging when connected to home power ...
RV battery was not charging when connected to home power. Followed mfg. instructions to troubleshoot and replaced with this same unit. Although when bench testing old converter, it said the old one was OK. But after installing this unit, batteries are now charging OK. So on bench test, I must have been getting a false positive. I contacted mfg. to see if they repaired old converter, so I could have a spare, but was told they do not repair them.

Great product for the price. Perfect fit on my 2009 Puma 27fq
I loved the modern design, looks very durable and works great. I had to install a female 120v plug in my converte bay since the previous faulty converter was wired straight from the mother board to the breakers and the new converter has a 120v male plug. But other than that i saved $800. Because the rv repair shop was going to charge me $400 for the converter and $400 for the install ,and it took me 1hr to fix it myself

Don’t be fooled by 12v output - it’s all about the amps!
Had a hard time diagnosing the problem at first. The original unit showed 12v DC output when disconnected from the panel. So I couldn’t understand why I had dead coach batteries after 4 days with full hookup to power. I kept looking for parasitic drains all over the coach without success. After some research online, I decided to replace this component and it fixed the problem. Evidently the old unit was still making 12v DC, but at very low amps - not sure how low, but not enough! I did consider upsizing from 55 amps to 65-75 to minimize my needed daily generator hours for charging the batteries while boon docking. Because space is at such a premium (as you can see in the photo) I decided to stay at 55 amps and retrofit all the interior lights to LED (22 in all) to lower the 12v load instead. This new unit was a direct replacement under the bed in my Fleetwood 31N Tioga Ranger. Receptacle plug for 120v AC power, 2 - connector lugs for the 12v DC power and a ground wire. Easy install and it works great. Hope the new one lasts as long as the original. I’m a happy camper now.

Problem solved...thanks amazon

Converter exceeds expectations
The WFCO Converter exceeded my expectations. The voltage output under various load conditions was carefully measured. Once the storage batteries were fully charged on the RV, the converter automatically dropped to a trickle charge to maintain the batteries in a static condition. The unit was easy to install and is very quiet. Each time the unit is turned on the fan momentarily runs regardless of load for the purpose of proving fan operation. My old converter tended to boil the batteries with an excessive charge during non-occupancy periods. That is no longer an issue with the new converter.

Exact Model
I have included before and after. This was an exact same model I was very surprised to find on Amazon. I had to replace my old converter in my 2007 Class A coachman. Most difficult part was finding where the old one was. Once found I had to figure a way to remove it and replace it with new one. Had to cut a hole next to fuse panel to reach in and remove old. Everything was a perfect match. Could not have been more pleased. Immediately noticed the difference with battery reading and able to turn on all lights and maintained same voltage. Old one my voltage dropped off immediately until power went of. I would highly recommend this product.

Light weight, easy to install
It has three charging stages. A trickle charge for when its parked, them a medium charge to carry your usage and a heavy charge when the batteries are really low in charge. I had to reuse the wiring from the old charger. Just cut the old wires off, strip a 1/2" or so of the covering off the old wires, insert the wire into the new charger, tighten it down, plug the unit in and your done. Great charger. I would buy it again.

Out with the old - Updated 4/21
Out with the old (was stuck on bulk charging ) in with the new. Old one was two stage this one's three stage. Old one used to buzz this one's silent. Can't even hear the fan when it's on for charging the batteries. In one month so far so good!
UPDATE
FT rv living so this is used all the time. After 6 months, still works perfect with no issues with electrical or battery charging. Btw I have 3 DC 12v batteries onboard.

WFCO is the best name for charger/converters.
This line of converter/chargers are the best imo for replacement in your OEM electrical distribution centers. Great for all RV and Travel Trailers. Automatic sensing determines which of the three stages your batteries start charging so you don't have to. Use deep level charge batteries, like marine or golf cart style. The price is a steal!
Question & Answer
Question :
Is this a smart charger
Answer :
It is. It has 3-stages to charge batteries as opposed to the "dumb" converters that only have 1.
Question :
Just ordered the converter, replacing same brand 45 amp with this 55 amp. As far as installation are there plugs in the back for the wiring?
Answer :
It has a plug to plug into 110 and then connectors for the other wires. Super easy to install.
Question :
is this convertors specs input 105-130vac 950w and output 13.6 vac?
Answer :
Output is 13.6 VDC. For recharging coach vsttery
Question :
can i charge 12 Volts Camry battery?
Answer :
If you mean the car battery, yes, but for the camper it is better.to use a deep cycle marine bsttery. They are made for the type of use that takes place in a camper. Car batteries are not. This is not a quick charger for car batteries.
Question :
What amp fuses does this converter use. They have been upgraded to 40 amps as 35s are not being made anymore. I want to make sure this is the latest version of this converter.
Answer :
I bought the 55 Amp converter so I'm pretty sure it was a 55 Amp fuse. I can't check, with out cleaning out my basement, because were my converter is placed in my RV, so i'm working off memory. I know for sure it isn't the 35 amp fuse. My old converter was a 40 amp fuse and I was thinking this one was higher or the same. Hope this is helpful.
Question :
is this converter compatible with a 100 amp AGM battery?
Answer :
Its compatible with any dry or wet cell battery.
Question :
if it is in original packaging, why is it described as used? Has it been installed? Does original warranty apply?
Answer :
I am not sure where you saw this one was used. They have both new and re-conditioned. Mine was new and was the exact OEM replacement. Works perfectly and solved my problems. Good luck.
Question :
I have a 30 amp converter, will the higher 55 amp one work for me? Thanks
Answer :
No reason that it will not work, Plugs up to 120volts & has 2 terminals to hook up battery leads. Should be a big improvement. Easy to mount.
Question :
I currently have a 8935 will this work as a replacement?
Answer :
I don’t know, check with manufacturer.
Question :
Can I put a separate battery in my camper an have this unit charge it from the truck when the truck is running?
Answer :
The WFCO needs a 110 volt supply, it converts 110 AC to 12 DC. in the camper you can hook another battery in series.
