Fair price with free shipping on genuine WFCO 75Amp RV converter. Direct replacement for the WFCO 65Amp originally in RV.
by:
fans run surprisingly cool. I have a 660ah battery bank and I can run a 12volt AC at max all day and my batteries are at 100%. You can hear the charge kick in every once in a while and top off the batteries. I'm very happy with this purchase.
by:
I recently upgraded to the WFCO 9855AD. It was very easy to swap the old for the new and I have had no issues with it. I know that there are some who have issues with the auto detect function, but there is a very good video on YouTube put out by the National RV Training Academy that explains how it works and how to set it up. There are no switches or jumpers that need to be set, you just need to make sure that the Lithium battery is below 50% charged so that the unit will go thru a complete charging cycle. Highly recommend watching the video.

The only concern I had in ordering this was the photo on the web site showed that this came with a different type of plug than the standard residential three prong. After talking with Ashley E. in customer service, I did order it and am happy to say that it does have the standard three prong plug.

Replacing a deck mount converter charger is extremely straightforward. I replaced our non-lithium converter charger with this one that supports lithium and is also auto detect. Like most RV's, our converter charger is in a location behind the power distribution panel so you have to remove that entire panel to get to it. Makes absolutely no sense but remember, we're talking about RV engineers. This is what makes the auto detect extremely nice to have. Once you have access it's just a matter of removing the old converter charger and wiring up the new one the exact same way. If you're like me and are overly cautious, before removing the old converter charger just whip out the cell phone and take a picture of the wiring. Before you button everything back up I would plug the RV into shorepower and make sure the converter charger is charging. It would suck to put everything back together just to find out it was not charging. Other than those few things, like I said, it's an extremely easy replacement.

I ordered this unit to carry in my camper for back up. I replaced the last one about 5 yrs ago. They a have a lifespan it seems, and want to have a reliable replacement on hand for our extended upcoming trip.
by:
Unit was received quickly. I have not installed yet due to finding out that the converter was not my issue. I am going to hang unto it as The One In my RV is 6 years old. And will eventually die out, and my icebox is 12vdc and I live full time in it. I think having a spare on hand is wise.
by:
I am going to switch my batteries from lead acid to lithium. This converter should be an updated version to be compatible with lithium battery detection. Looks like an easy switch I can do myself. Easy order process and prompt delivery. Thanks.
by:
I needed to replace the converter on my RV to switch to lithium batteries. I originally tried to save some Pennie’s by purchasing a cheaper brand on Amazon, big mistake. I should have known spending a little more money and getting service and advice from E-Trailer would save me time and money in the long run. The unit worked immediately and flawlessly so far.

Thanks for sharing your experience! Glad to hear everything is working smoothly with your new setup. Making the switch to lithium is a big upgrade, and it’s great that the converter performed right out of the box. We appreciate you giving us a shot and are always here if you need anything down the road!

by:
I purchase the new auto-detect converter charger so that I could upgrade my battery on my rv to a lithium battery. As promised it was a simple disconnect 3 wires remove the old converter and install the new converter and reconnect the 3 wires. I was told that I would receive the converter on Monday, but it showed up on Saturday, two days early. Thanks e-
trailer for the great advice on the converter and getting it to me quickly.
by:
Product was easy to install and all of my 12V load started working properly immediately.
by:
The purchasing process was very easy and easy to track the shipping. Kind of cool how you guys post pics of the staff handling each phase of the process. I purchased this converter as a spare as im guessing mine will fail soon enough since the cooling fan no longer works. In the mean time I have the comfort of knowing I have one on the shelf if mine fails.
by:
Great site selling authentic parts! Bought this unit after being ripped off by A**zon sending me a Chinese knock off after I paid for this exact OEM part and was sent a cheap copy for $333.00 ! Etrailer sent me the correct part fast for the same price. You guys have gained a customer for life.
by:
So far, so good. Quieter than the factory converter and easy to install. I like that it can be used with Lithium batteries too.
by:
Exact same item, exact same fitment.
Emily the rep made sure I got the correct item, shipped quickly. Made for a quick simple replacement.
by:
Got it, intalled seems to work just as it should. Thanks for rapid shipping.
by:
Installed inverter and works as intended.
by:
this was a match when I did a Google search. for my converter on my horse trailer. My first order was lost in the mail and did not come till five days late, so I had already placed a second order to be shipped differently and it arrived promptly. Customer service was great working with me to get the new order out and I am in the process of returning the delayed order. This was easy to install since it was a match and is working great!
by:
Brielle understood my needs perfectly and helped me look for an upgrade, this is the best one available. She was great, installation was simple, works great.

This one started right up and is working as expected. However, this is the third WFCO Auto-Detect 55AMP in a coach that is only 4 years old. Each time it stops recognizing that we have lithium batteries and stays at a charge rate of 13.4 instead of 14.6 volts. We continue to purchase this unit because it is the only unit that will fit in the space that Airstream 30 Classic gave us. Keep your fingers crossed on how long it works. It never died; it stopped charging the lithium batteries correctly. It is easy to install, two wires, a ground wire and plug in behind the electrical panel.
by:
The converter is working great. I would highly recomend for fast charging. I am using it with 4, 100ah Li batteries.
by:
Direct replacement of non auto detect unit with a cooling fan failure. Works as it should. Fast delivery!
by:
Product came quickly and packaged well. item was a drop in replacement for original equipment.
by:
Was simple to install. Direct swap for the old WFCO Converter. Seems to charge the lithium just fine.
