Outstanding I looked all over for this part and the few I found the soonest I could get one was at least 8 days out. I found one with you people and I couldn't believe that besides free shipping, for a few dollars more I received it The next day. It arrived and was the perfect replacement. Thank you so much
Very quick shipping. Product was installed by an etrailer recommended RV repair tech - Patriot RV Tech, Fort Worth, TX. Everything checked out OK when installation complete. The converter box was charging the battery as it should. Won't know how it really works until we go on vacation later in the year.
The included instructions were excellent. No awkward English, just clear step-by-step instructions for a variety of scenarios.

No problems after a year of use on the grid or solar.
Works great. I have an older mid 90's travel trailer, very nice retrofit to update. multistage charger works great, there's documentation that shows the charge profiles and this will be much healthier for batteries. Voltage is rock solid and right on par. Unit is much quieter than the old humming transformer, lighter, etc. Has LEDs to indicate blown fuse or stray load on a circuit, install pretty easy if your familiar with electrical, but it was a project. I changed out my 110v breakers as well while I was at it(BD style) as they were 30 years old, just got them from home depot. Nice rebuild. There is a charge status indicator on fuse board that blinks green, since my bed is right next to it, some light escapes out the cover, so I just put little piece of electrical tape over the led, but it for most people probably not an issue. Also the turbo boost charge mode is nice when running off grid, I can top my 2 batteries up off the generator in half hour while making breakfast and be good for the whole next night of running CPAP. also the low and slow maintenance mode is nice for long term storage. Highly recommend doing upgrade if you have this style Magnatek converter in your rig
This is a quality product much better than the converter that I am replacing easy installation fit like a glove I will be buying all my RV parts from E trailer from now on
Product fit the space correctly, was reasonably easy to install provided you are capable of this type of task, and appears to be operating as promised. Written Instructions were a bit lacking, which necessitated me calling and speaking with the manufacturers technical department.

Product has worked flawlessly and reliably. The peace of mind we have after installing this modern unit into an older RV cannot be measured. We would make this the first upgrade to any RV, every time. Wonderful purchase.
I have a 2000 Skyline Layton trailer. I recently upgraded from lead acid batteries to a LiFePO4 battery. This new 35 amp smart converter makes it possible for me to get close to 100 percent charge on my new battery as opposed to about 80 percent with my old converter. It works great!
It worked great ,install went smooth,could not ask for better,now my battery charges and lights even seem brighter. thanks for your help
It got here before estimated. Fairly easy to install.
This converter fit perfectly into the existing panel housing from my 1998 class B. The new converter arrived super quick and installation was a breeze. Couldn't be happier with this purchase.
Upon arrival, a thorough inspection was conducted. Everything appears to be as described. I can't simulate or test this unit due to lack of equipment; hence, functionality shall be determined after installation.
The folks at etrailer are ON IT! Incredibly, Receive my part in 3 days!! Installed and working! Thank you etrailer.com!
Works great, instructions were good. 5 years ago I would have paid less than half but whatever, my camper works now.
This power converter works great and is an easy swap out for the OEM unit!
Prompt delivery.
Easy to switch out. And I'm not an electronics guy. Replaced the model 6332 in my '94 Prowler.
Easy replacement. Works well.
Perfect. Thanks
Shawnee was amazing in reaching out to me Everytime there was progress w my order. Was back ordered then was in stock but shipped to a physical address but the USPS didn't deliver it because I don't have a mailbox(could've left on porch). Called etrailer and Shawnee took it on herself to ship a new one and expressed it. Glad to see some businesses are still working in the before Covid mentality
A quality product in every way! The installation instructions could be a little more detailed !!
Exactly what I wanted. Good instructions for installation. Install the Unit and everything is working again.
I’ve got a 1988 Big Foot 5th wheel that I upgraded to a 200 amp hr AGM battery and this works great in conjunction with that. Got to say that etrailers shipping is great!!
