I bought this jack after doing a lot of research. The conclusion I came to was that most of these electric jacks are basically the same design with a different name stamped on them. I like how this one has an inline fuse, a higher lift range, and an adjustable footplate. I read a lot of forums, Facebook pages and reviews on a variety of websites. Etrailer offered the best option for what I was looking for. This jack is well made. It's heavy and solid. It was super easy to install. If you can't install this, you probably shouldn't be pulling a trailer. It was literally 3 bolts and a ring terminal. The wire lead does not come with a ring terminal attached. You have to add your own, which is no big deal. It comes this way so you can cut the excess wire to fit your application. It also came with 3 washers and 3 star washers to ensure a good ground connection on the wiring. The light is super bright as well. Etrailer kept me up to date the whole way through the ordering and shipping process. This was my first purchase from them and it was a great experience. 438735

I just got this, opened the box, hauled it out to my trailer (which was stuck due to a frozen 'jack; already removed) and had this one installed and wired in about 5 minutes. And it worked; confirming my diagnosis that the old one was 'toast'. The only improvement that I can think of would be to incorporate a 'hanger' for the 8 pin plug when not in use.... So I pulled the old one off the dead jack and ziptied it to the main upright. Problem solved. The only reason there are only 4 stars is that it worked TODAY. In a month I may have to review again but shipping was fast and free. The jack worked well. So..... so far; no complaints! 571675

After purchasing a small camper and using the hand crank jack two times that I would look for an electric jack to replace it. Many of the jacks cost more than I wanted to spend. Then I found "etrailer.com". The prices were reasonable. I ordered Item EJ-3520-BBX electric jack. I have had it for a year now and have used it many times. I truly a happy camper. It has saved me time and energy. My wife can operate it and has no trouble letting me fish while she breaks camp with no help at all. The follow up service is great. Check "etrailer.com" before you buy any where else. 566675

What a easy upgrade for your camper. I ordered and received in a few days. etrailer just does it right. Install was so easy, anyone can do it. No more cranking for me, push the button and like majic, you can take your trailer up or down. I also purchase the cover to keep the weather of the motor and controls. It is nice too. Thanks Lisa D for your great service. 496356

My electric trailer jack came at noon today. Got home from work at5:30 and had all hooked up and running in 25 minutes! Easy to install! Was worried about the motor head being too tight against propane bottle cover...but it fit perfectly!Runs super smooth so far. I put up with a hand crank tongue jack for far too long. Seems like a good product for a reasonable price!! 394253

Very solid and heavy duty jack, with bright LED lighting, manufactured by Ram. Adjustable foot piece for quicker adjusting... Jack pretty easy to install, with single wire electrical connection and 3 bolts. Jack has low gear ratio and foot shaft moves slowly, but has plenty of power to lift front of trailer. Plenty of clearance behind jack for propane tank cover on our Airstream. Replaced more expensive model that was bent at mounting flange being winched onto transport trailer. 474270


Comments
Jack is still slow and steady and has worked perfectly since installation... The adjustable foot unit is about an inch too tall for at lowest position some sites, based on low hitchball height of our tow vehicle, but we have used the shorter foot from prior jack as an alternate, and that solved problem...

Great customer service. After receiving a damaged unit on Tuesday the 26th, I called and spoke to Sal and emailed him pictures of the damages. Also they had originally sent a white one but I had ordered a black one. They immediately shipped a new black undamaged unit and I just received it on the 29th and got it installed. The damaged unit is on it's way back to E trailer. I have purchased many items from Etrailer and am very pleased with their service. 463641

I had to enlarge the hole in the tongue with a rotary file but after that the installation went well. Have used it for about 6 trips now and dont know how I ever did without it.

Purchased for a 2015 Tracer 238 Air Travel Trailer. It works as advertised. It comes with a single cable which is connected to the + positive side (red) of the battery. It is a slow process & like all new products there is a learning curve. My only regret is I didn't purchase one sooner. Make sure you buy a cover to protect your investment. I've also added an internal 30A surge protector, 30A automatic transfer switch, rear cargo carrier & generator to my trailer. I hope this helps. 477769

Good product so far. I have a suv and the rear door swings up. The door doesn’t hit the top of the jack. It hooked up easy but the main positive wire was busted up about on foot from jack. I didn’t like doing a extra splice but it’s all good. 464837

After four camping trips with a manual tounge jack, I decided to buy an electric one. My last camp site was 8 inches off level and that was enough for me. I installed the EJ-3520-BBX this afternoon. Everything worked fine except for a few tweaks. The lower a-frame hole for the tongue jack was too small so I had to use a sanding drum on a drill to open it up so it would fit. Not a big deal to me but might have been for someone non-mechanical. Not sure if that was a trailer problem or a non-standard tube diameter. The jack light (three LED's mounted on a circuit board) under the jack screw and motor cover had become completely dislodged from its slotted mount and was just floating around in the plastic housing. I took the cover off, re-mounted it and used stainless washers under the cover screws to prevent them from digging into the plastic when I put the cover back on. The jack works as advertised, and even picked up the rear of my Ram 2500 Cummins several inches to facilitate putting my Blue Ox WDH sway bars on. The tongue weight of my trailer is 650 lbs so I'm guessing it picked up well over 1500 lbs. I found an old dry bag and it fits perfectly over the jack to protect it from the weather. So far I am pleased with it but wished the manufacturer had used and automotive type spade fuse instead of the antiquated tubular glass fuse. Only time will tell as to the durability and longevity of this product but I am optimistic and there is a manual crank included if something goes down. A tick over a hundred bucks can save one a lot of aggrevation! 443807


Comments
Generally, I am happy with the product it has adequate power to lift my 900 lb. tounge weight plus lift the rear of my Ram 2500 to facilitate installing the spring bars of my Blue Ox WDH. However, what I dislike about the jack is the fact that there is no limit switch either up or down. It is possible to over-extend or collapse the jack when that happens, you can hear the gears slip a tooth which Im sure, over time, will incapacitate the jack.

Would have to say 4.5 on the rating only because of the installation instructions. On installation instruction #4 it tells you how to assemble the hardware and then directs you to a figure above. This figure is nothing more than the plain jack. Then it tells you on #6 to position the fuse holder as close to the power source positive terminal as possible. The fuse holder comes in already attached to the jack adjacent to the jack control switches. Ease of installation other than above. Common sense will get anyone past those directions. Jack operation was perfect after installation. Test of jack showed it works as advertised and I can't wait to use it in the upcoming camping trip. Ordering, customer service and shipping/receiving was excellent. I was informed on the delivery date and status of shipment by ETrailer to whole time. Properly packaged and the unit came in in excellent shape with no defects. As you can see in the pictures it is a clean install and I added a very nice cover which was also sold through E-Trailer. Another nice product to finish a successful installation. 379431

This inexpensive travel trailer jack arrived after only two days via UPS. Securely packaged. It is truly a quality item! Very easy to install and works great. The manual handle is a bonus in the event it is ever needed. Be sure to follow the instructions making sure the three screws on the plate are solidly grounded using the supplied star washers. I can honestly say that this jack is one of the best items I've ever bought for my RV. Thanks etrailer! 480612

The old jack on our tent trailer (2" outer pipe) was getting harder to crank, and just didn't have the reach of this 12v powered jack I read about in an eTrailer email. I felt somewhat sure of the measurements and ordered it. It came on the third business day which was terrific as we're headed on a 5,000 mile odyssey up to Maine and through New England starting three days later. I rechecked the measurements, and note that, without the footplate, the lower level is 7" with about an additional 1-1/8" reveal of the inner 2" pipe. Installation was basically easy, and the holes lined up perfectly to re-use the original bolts along with the furnished washer hardware. In my case, the lower plate was LESS THAN 2-1/4'' and I spent a few minutes cutting with a Dremel tool to accommodate the lower pipe. The electrical hook-up was simple. I normally leave the negative connection to my battery detached, and this unit won't work without it re-connected since it grounds the frame. The upside of that is that you don't need to have an inline switch to thwart mischief, simply disconnect the negative cable to your trailer battery. This unit gives me much more range of height, the motor is powerful and quiet, and moves at a reasonable pace. The included footplate adds more height, but I'll use a short, flat one as a matter of convenience. Everything was as described, except for the measurements. I'd note that the top box is a full 8" deep. For us, that means I can't open the back gate of the tow vehicle when attached, but we'll change our discipline and put last minute items in the storage area of the trailer. Well done, eTrailer! 441983

Used it for about 5 dry camping trips last summer with my 24' toy hauler. Works fine, has plenty of power to lift the tongue off the trailer hitch even when it is somewhat bound to the hitch ball. Bought a cover to keep it covered and out of the high elevation sun. It sure saves a lot of manual labor fighting with the manual hitch crank. 730284

I checked out a lot of reviews before buying this jack. Part of my decision was based on the price point and that it has a higher lifting distance than some of the others. Installing the jack was a snap. Just mount the trailer on your trucks hitch for temporary support during the change over and you're off to the races. The bolt pattern matched the old manual jack so no issued there. Even with the washers that come with the electric jack my original screws were still long enough (you will need to reuse yours, the electric jack doesn't come with any). I simply zip tied the wire to the existing wire bundle under the A-frame. I did buy a ring kit to attach the end of the power wire to the battery properly. I did not cut any length from the wire as some reviewers had advised. Just coiled up the excess. The jack worked right away. I think I heard my aging shoulder breath a sigh of relief. Afterwards. I did order a cover for the electric jack head. I figure the unit will last longer if the sun isn't always burning down directly on it. So far, I would recommend this jack. Time will tell. 543425

Customer Service is number 1!! Mr. George is awesome on ensuring you receive the product and are satisfied. I had the electric jack installed in less than an hour. That included reading instructions, acquiring the tools, running electrical check for hot wire, and replacing the tools. I used the electrical box under front of the trailer for the power. To ensure I would not chaff the wire, I selected a hole in the box and drilled it to 3/8". I then drilled a hole in a valve stem cap so the wire would slip through the valve stem cap. I then pushed the cap into the hole and wired to existing electric wires with wire cap. 491854

I installed this jack about two weeks ago on a 22' travel trailer, and have only used it 3 or 4 times. This is the first electric jack I have owned. It was a breeze to install, only took about 10 minutes to replace the manual jack. If I would have known how easy they were to install I would have replaced my manual jack several years ago. I didn't rate it 5 stars because it operates slower than I expected, (may be normal) and I originally had trouble getting the jack to work. Seemed to be stuck or the gears out of sync. I took the manual crank and worked the jack back and forth a few times to get it going. Works good now. For the price I'm very satisfied. Only time will tell how the jack holds up, but if I can get 3 years or so out of it I will be happy. Sure beats cranking the trailer up and down by hand. I had a an old laptop case that I am using to protect the motor unit from the weather and it seems to do the job. 489608

Great value for money. First, the manual crank works better than the original manual only jack. Second, my wife finds the electric option very helpful. The physical installation is very easy and it fits right where the original jack was. The downside is that installation is simple but needs planning if your trailer doesn't already have an electric jack. You need to plan to put a large 12V battery on the trailer and then wire it in to both the jack and the trailer to tow vehicle connection. That connection is needed since, in our experience, even a charged car battery won't last for a complete raise so the tow vehicle connection is needed to supply the extra needed power to complete the lift. 572020

This was an excellent choice. It has lifted the tongue of my very heavy 16 ft enclosed trailer, fully loaded with approx 7000 lbs, many times. It has never failed to operate just as it should. And, the price was excellent. Pushing the button versus cranking a jack is a no brainer. Would buy again without hesitation. 571933

I have installed the tongue lift on my camper . It fit perfectly and it operated just fine . No problems so far . I used a small battery clip on the hot wire from the lift and when I need to use it I simply clip it to the 12 volt battery on my camper . The way my camper is wired the ground wire from the camper to the battery has to be hooked up in order for the lift to operate . But I am very happy with it so far . By the way what is the warranty on the lift ? Sending pictures also of installation . 471421

Reason being that sometimes the trailer jack needs more power than the 12V wire from your tow vehicle can deliver.

  • Determining the Correct Electric Jack for Jayco 22FB Trailer
    There are no obvious cons to having an electric jack as opposed to a manual jack and most people prefer an electric jack due to its ease of use. As for what electric jack you need for your Jayco 22FB, that is going to depend on the diameter of the jack hole; it will need to accept the outer tube diameter of the jack. For example, the Ultra-Fab Electric A-Frame Jack # UF38-944017 has a 2" outer tube diameter, the etrailer Electric Jack # EJ-3520-BBX has a 2-1/4" outer tube diameter and...

This should hopefully give you the needed clearance to drop your Ram's tailgate.

  • Electric A-Frame Jack Recommendations for a Utility Trailer
    If you already have a battery on your utility trailer and you really like how the etrailer Electric Jack w/ Footplate # EJ-3520-BBX performs (thank you by the way) then I recommend just going that another one. Since it has a lift capacity of 3,500 lbs you will have more than enough power to get the job done. If you don't already have a battery on your utility trailer then I recommend using the Trailer Valet JXC instead. This comes in a 2K # TV54FR and 5K # TV94FR version for an A-Frame...

  • How Much Does An Electric Trailer Tongue Jack Need To Be Rated For
    In regards to selecting a tongue jack for a trailer, it only needs to be rated for the tongue weight of the trailer which is usually 10-15% of the gross trailer weight (GVWR).

  • Can an Electric A-Frame Trailer Jack be Mounted Sideways for Hatch/Tailgate Clearance
    A-frame jacks have a specific mounting pattern using 3 bolts in sort of a triangle configuration. But they are not spaced equally apart meaning if you turn a jack 90 degrees the holes would not line up in most cases. If they line up on yours then you can mount the jack that way. Otherwise you will likely have to drill. There is an easier solution though and that is to use a longer ball mount so that the trailer sits a little further away and eliminates the chance of interference with...

  • Solution for Gaining Tailgate Clearance with Trailer Hooked Up
    The head by itself on the etrailer.com Electric Jack w/ Footplate # EJ-3520-BBX cannot be rotated, however you could potentially rotate the entire jack (the mounting holes are asymmetric) on the trailer A-Frame to see if that provides the needed tailgate clearance.
