etrailer Trailer Jack - e33KV

Highlights

Push Button Lifting: 5,000 lb electric jack raises and lowers your trailer through a direct 12V power connection.
Check Tongue Weight While You Load: Jack foot scale reads up to 2,000 lbs in 50 lb increments without setting up a separate scale.
Adjust Cargo Before You Tow: Check the reading, move cargo, and check again while the trailer is still supported by the jack.
Drop Leg Adds Reach: Extends up to 4-1/2" to reduce jack travel during setup.
Protected for Weather: Weatherproof buttons, crank cover, canvas jack cover, and black powder coat help protect the jack.
Automatic Reset Protection: 20A automatic reset relay fuse protects the jack motor from overloads and short circuits.

Features to know about

Check, Adjust, and Hitch Up

When you're getting ready to tow, it's hard to know if your trailer's tongue weight is right just by looking at it. Lower your trailer onto the gauge while it's still on your jack, see where the weight stands, move your gear if needed, and check it again before you hitch up. Because the scale replaces your jack foot, there's no separate tongue weight scale to deal with every time you check your load. Four mounting positions let you rotate the gauge toward the side that's easiest to read. If you use your trailer on gravel, grass, or other soft surfaces, the scale also works with the 6" Round SnapPad (SN47FR - sold separately) to help keep the jack from sinking.

Power Through Hitching

The 12V motor raises and lowers your trailer with the push of a switch instead of a manual crank. The drop leg extends up to 4-1/2", helping you get closer to the ground before using the motor. A built-in LED lights your coupler when you're hitching up before sunrise or after dark, and the included manual crank keeps the jack usable if electrical power isn't available.

Ready for the Weather

Moisture takes a toll on trailer jacks, so this one uses weather protection to help limit damage over time. The jack is made of black powder coated steel to help resist rust. Weatherproof buttons and the rubber cover over the manual crank opening help keep moisture out, while the included canvas cover helps protect the jack during storage. The 20A automatic reset relay fuse protects the motor from overloads and short circuits.

Direct 12V Power

This jack wires directly to your trailer's 12V power source, so it doesn't rely on your vehicle's 7-way connector for operation. Top-mounted controls keep operation straightforward from the jack housing, and the automatic reset relay fuse resets itself after an overload or short circuit instead of requiring a replacement fuse.

Received it today and it was an easy install. The jack seems very sturdy and easily lifted the 1200 lb. trailer tongue. I used the tongue weight scale, which was very easy to put on and take off. The weight display gauge was easily readable. The jack is a compact design and, with the weather cover, seems like it will be well protected from bad weather.

Glad you are liking it so far, Koan! We are pretty proud of this jack and I'm sure it will serve you well! ^___^ What kind of trailer did you install this on?

Out of the box…looks great. Installation was easy, however, a couple additional steps needed to be performed to make it work with our model trailer. Our current trailer is a 2004 Keystone Tailgator toy hauler.
The shaft of the electric jack went into the first hole fine but the second hole was just a touch smaller. The second hole had to be ground out a little bit to make the shaft pass through the second hole so the jack could seat properly on the triangle.
When I removed the original mounting bolts, some of the threads on the bolts were stripped so the new bolts provided with the new jack would not screw on. I drilled out the hole to accommodate the new bolts which worked fine.
Attaching the hot to the battery terminal and the ground to one of the jack bolts worked perfectly. The jack sounds strong and worked as it should. The LED light up front is so much brighter than the old light.
Very pleased with the unit. I can’t wait to see how it actually performs when hooking an unhooking while camping.

This jack install was quick & easy. I like that the hardware includes plastic inserts lock nuts, needed or not, I used them. My 25 Expedition doesn't provide enough amps without putting truck electronics in jeopardy. I'm not interested in having an on-board trailer battery, so I wired up connections for a jump starter. Works like a charm numerous times on single charge. I have EXACTLY the setup I was aiming for. Love this jack!

by: James 04/17/2026

Jack is plenty good, seems well designed and built plus the cover actually feels heavy duty compared to others. Installed on a race trailer since we had a battery in it for the winch so why not. Welded a piece of 6" C channel into the A of the tongue close to the body so the truck tailgate would clear it. Drilled the holes out further than typical so didn't have the mounting problems others had with washers not sitting flat. The reason for the 4 stars is why in heaven's name the ground wire couldn't have been the same length as the power wire to reach a battery without soldering in an extension?!? Not a show stopper but geez- I'd have paid the extra buck for 2 more feet of wire. For anyone reading this and wondering no, I purposely did not ground the battery to the trailer, less problems going direct to the battery for high-draw stuff.

Glad you are liking it, James! Well, mostly anyway. I will talk to our product development guys to see what we can do about a longer ground wire. Wouldn't be a bad idea by any stretch of the meaning. What do you tow in your race trailer?

James

4/21/2026

@LazerS- That'd be good, If anything someone can run it somewhere protected so a chassis ground won't corrode if that's what they are using, another reason to run direct to the battery. We run at some local dirt tracks; our 14yo drives a Hornet (AKA FWD if you're not from the Midwest), fun family hobby!

by: Chris B. 07/07/2026

I really like my new electric jack. I got the 3500lb capacity which matches my oem jack. Iwas going to get the 5k but i decided to stick with the 3500lb. And i have been happy so far. I have a ST2916 stryker toy hauler. The tounge weight can get close up to 2k lbs. The jack handles my application like a champ. I usually have to lift the jack high enough to facilitate the install of the stabilizer bar, so it essentially starts raising the truck a bit. No issues so far. It actually actuates faster than the 3500lb lippert oem jack I previously had on. I like how it has an extension at the foot. It's very practical. I also like how the toggle switches are located near the top of the jack. My lippert oem has the toggle switches on the front of the jack facing the tail gate. I had to be careful not to hit or bump into the toggle switch as I moved/jump over to the other side. I did end up breaking toggle switch once becausei bumped into it. That was an expensive fix.i don't have to worry about that now.
The only con that I can think of is that the trailer does seems shake a bit as I'm retracting or lowering the trailer. At least more than I'm accustomed to, but it hasn't been an issue so far.
So far I'm happy with the jack.

I was assisted in a chat session on a Sunday afternoon. I gave the representative the model number of unit that had to be replaced and in less than a minute was told that this unit is an exact replacement. I immediately ordered it and it was shipped that same day. The the e23ZV is a perfect replacement for the Jayco Jay Feather Micro 199MBS. Fits nicely under the tongue mounted bike rack. I already installed it and it performs perfectly.

Glad we could help, Vincent! Glad it worked with the bike rack as well! ^___^ Cool camper as well! What's the next trip you have planned?

@LazerS Thanks for responding to my review. Last week we camped at Wildwood State Park in Wading River, NY. The new tongue jack performed flawlessly; it picks of the rear of the tow vehicle with ease (necessary due to the type of weight distribution hitch). Next trip is Hither Hills State Park in Montauk, NY and then Smith Point County Park in Mastic, NY. Thank again!

@Vincent Nice! Look like pretty epic camping sites! And good on you for using the jack to help install the weight distribution system! We hear a lot of people saying how hard it is to get those installed until we tell them about the jack trick, and man does it help! ^___^ Have fun on your upcoming trips and just let us know if there is anything else we can help with!

by: Jonas 04/18/2025

Superb! Operates nice and quiet compared to my factory model. Installation was a breeze. Price was amazing. I do encourage others to get one, because it operates smooth and quiet. The smaller design over the factory one allows more space for the tailgate operation as well.

Look's great on your trailer, Jonas! I know being able to open the tailgate sometimes is a major hurdle for a lot of people so I'm glad this new jack gives your the space for opening yours.

Bold holes lined up on my Winnebago Minnie 2500rl perfectly. Received unit, mid day, mounted, and did electrical all in the same day. I also like having the internal circuit breaker rather than a "burn out" fuse. Storage cover is a nice touch too.

That’s awesome to hear, and it looks like a clean install on your Minnie too. And I like that you called out the internal circuit breaker. That was a deliberate design choice to avoid the hassle of inline fuses, so it’s great to hear that’s something people actually appreciate in real use. Where are you taking the Minnie next?

Jack works well after a year of service, a real improvement over the hand crank model. Easy to operate 5 star rating.

by: JohnJ 03/26/2026

Just installed it. Jack went on fine, bolt holes matched my 20’ Haulmark enclosed trailer exactly. I had to run power to the battery, and that took the longest.once connected, lifted the trailer right off my floor jack. Now I just need to tuck and zip tie wires.

This trailer jack works great! I set mine up to run off a small 30amp hour lithium battery that I store in the tongue box. It works great, and I can level and make adjustments without having to connect to my truck. The jack works quietly and quickly.

by: Rod W 09/09/2026 One Year Later

This is a great tongue jack, super easy to install. And most importantly, it's dependable! It's been so dependable that I don't even think about it, that's a great thing. If it has one downside, it's the speed, it's slow. But I get torque (lift power), speed and battery drain all have to work together, you can't have everything. For example; if you wanted faster speed with the same motor, you could just reduce the gear-ratio but then it would no longer be rated at 5000lbs, it would be less. Put on a bigger motor to get the torque (lift power) back to 5000lbs and you'd have more battery drain and so on. This jack has a good balance of those three things. I'd definitely buy this jack again.

by: Mary 09/17/2026

Installation was fast and easy though it's a drag the the ground wire is designed to be too short to reach the battery. Fastening it to the frame in an area sheltered from dirt and moisture is easy enough but it's the step that took the longest.

The unit is much quieter and faster than the Domestic it replaced. I didn't really want a drop leg because my old lady arthritic hands don't need another little fastener to deal with but it seems that it will work well.
I like the larger base and the protective cover over the controls. It has everything I need and none of the extras I don't. So far I'd recommend it.

Bolted right up to my popup, 10 minute install, works great. Will it stand the test of time is the only question

Unfortunately the casing can not be opened up with out destroying it. I thought I would be able to wire it up with the existing trailer hot wire directly to the mower, but ended up have to splice into the camper wire harness. Not what I wanted, but made it work.

by: Nick 10/19/2026

This is very easy to install. Much quieter than the stock one that came with my Gulfstream travel trailer.
The light is bright and the reflective tape makes this a great upgrade to what I had before

by: Ken 08/12/2026 One Year Later

E Jack is a great conversion. I didn't put a battery on trailer to run it. I simply used RV flat pin receptacle and used ground and power post, runs jack fine and you do not need vehicle running to use jack

by: Doug 08/14/2025

Extremely professional Paula was prompt in assisting me with my questions. Electric Jack works fine. Installation on my 2022 Nucamp Tab 320 required 2 modifications to fit. #1 the bottom hole on the A frame prevented Jack from mounting. Had to reem out hole to allow Jack to seat. #2 tailgate of SUV hit top of Jack power head. Had to mount head sideways to allow tailgate to open. Makes the light on the front shine away from intended target.
