If you’ve ever spent ten minutes cranking a manual trailer jack after a long drive, you know the pain in your shoulders and the frustration of missed camping time. An automatic trailer jack transforms that chore into a two-second button press, letting you focus on setting up camp instead of fighting a rusty crank handle.
I’m Min — the co-founder and writer behind Gadgets Feed. I’ve spent hundreds of hours researching the mechanical engineering, motor torque, and real-world durability of electric tongue jacks to find the models that genuinely simplify your trips.
After analyzing lift capacities, travel speeds, weather resistance, and thousands of owner experiences, I’ve curated this guide to help you find the best automatic trailer jack for your specific trailer and budget.
How To Choose The Best Automatic Trailer Jack
The decision comes down to matching the jack’s mechanical capacity to your trailer’s tongue weight and your typical campsite terrain. Ignoring either leads to slow operation or outright failure at the worst moment.
Lift Capacity vs. Static Load
Dynamic load is what the jack must lift (trailer tongue weight) while raising and lowering. Static load is the weight it must hold once the trailer is disconnected. A 3,500-pound dynamic jack easily handles a 5,000-pound travel trailer’s tongue, but if you plan to keep the trailer attached, a unit rated for 4,000 to 5,000 pounds dynamic is safer for heavier rigs.
Stroke Length and Drop Leg Travel
Total lift height — measured from fully retracted to fully extended — combined with a multi-position drop leg determines how level you can park on sloped or uneven ground. An 18-inch stroke with an 8-inch drop leg (like the 27-inch total range on the POLESTAR) is far more versatile than a fixed 14-inch stroke when your campsite has a significant grade.
Build Quality and Weather Resistance
Look for powder-coated or zinc-plated outer tubes, stainless steel hardware, and a motor cover that keeps water out of the gear housing. Units like the Stromberg Carlson use heavy-wall steel tubes and weather-sealed switches to survive Canadian rain and Arizona sun alike.

In‑Depth Reviews
1. Lippert Smart Jack 643589
The Lippert Smart Jack is the most thoughtfully engineered automatic trailer jack at this weight class. Its Auto-Hitch Memory function remembers your hitch height after the first setup and returns to that exact position every time you reconnect. The backlit monitor illuminates when touched and switches off to save battery, while a battery indicator prevents you from discovering a dead coach battery at 2 AM.
Helical-cut gears make this one of the quietest jacks on the market, and the 30-amp 12V motor lifts a 30-foot travel trailer without audible strain. The large 9-inch footplate provides stable footing on soft ground, and the housing is a textured, chip-resistant composite. Total lift reaches 22.5 inches (18 inches of screw travel plus 4.5 inches of drop leg), which handles most OEM tongue setups.
Users consistently report 20-minute installations because bolt patterns match standard A-frame mounts. The LED halo light is genuinely useful for nighttime hookups, and the auto-retract feature spares you the annoyance of holding the switch down while waiting for full retraction. Some units arrive with cosmetic housing cracks from shipping, but Lippert’s warranty support typically resolves replacements within a week.
Why it’s great
- Auto-Hitch Memory saves time on repeated hookups
- Extremely quiet helical-cut gear drive
- Battery indicator prevents dead-battery surprises
Good to know
- Plastic housing can crack during shipping
- Higher price than comparable 3,500 lb units
2. Husky 82022 Super Brute
The Husky Super Brute stands alone as the only jack on this list with a wireless remote control, letting you raise or lower the trailer from the tow vehicle’s cab or safely away from pinch points. Its 5,000-pound lift capacity exceeds most half-ton hitch tongues, making it a legitimate pick for larger travel trailers and enclosed car haulers. The core engineering feature is a 20mm ball screw design that reduces friction and amperage draw compared to standard Acme threads.
The backlit control panel includes soft-touch switches and a three-sided LED light system that illuminates the hitch area far better than the single-LED designs common at lower price points. The 6-foot, 10-gauge power cable handles the higher current draw without voltage drop. Husky also provides a lockout feature on the remote to prevent accidental activation while driving.
Owners praise the quiet operation and the fact that a full 18-inch cycle takes about 60 seconds with a 5,000-pound load. The warranty support is excellent — one reviewer’s unit failed after a month and Husky shipped a replacement within 48 hours. The main drawback is that the jack does not include mounting bolts, and the remote battery door is not sealed. A few owners report the switch relay failing after three years, but the overall build is stout for the capacity class.
Why it’s great
- Wireless remote fob for safe distance operation
- Ball screw drive reduces motor wear and amp draw
- 5,000 lb dynamic capacity for larger trailers
Good to know
- No mounting hardware included
- Remote battery compartment lacks a weather seal
3. Stromberg Carlson JET-3755
The Stromberg Carlson JET-3755 is a straightforward, no-nonsense electric tongue jack that prioritizes durability over gimmicks. Its built-in motor protection automatically shuts off the jack if it overheats or draws too much current, then reconnects when the motor cools — a feature absent from many budget units. The heavy-wall 2-3/16-inch steel outer tube and weather-resistant switches make this a genuine all-weather companion.
Total lift is 23 inches: 18 inches of screw travel plus a 5-inch drop-down leg. The integrated dual LED work lights illuminate the hitch area for nighttime operation. Installation requires wiring both red (positive) and a ground connection using star washers against bare metal — the manual omits detail here, but experienced DIYers will manage in under an hour. Owners love the fast cycle time compared to cheaper models and the oversized footplate that distributes weight well on gravel.
The unit uses a cartridge-style fuse (some prefer blade-type for easier replacement), and the mounting bolts must be sourced separately for certain trailers. A few units arrive with the plastic cap chipped in transit, but the jack itself functions reliably. For the build quality and motor-protection circuit, this is a solid mid-premium choice that avoids electronic complexity.
Why it’s great
- Motor overload protection prevents burnout
- Heavy-wall steel tube resists bending
- Fast cycle speed for a 3,500 lb jack
Good to know
- Installation instructions lack wiring diagrams
- Cartridge fuse style less common than blade
4. KYX Electric Trailer Jack 7500LB
When your travel trailer or horse trailer exceeds 5,000 pounds of tongue weight, the KYX 7500LB becomes the obvious choice. Its 7,500-pound dynamic capacity is overkill for most single-axle campers, but it provides ample headroom for triple-axle rigs and toy haulers. The 12V DC motor is paired with an internal circuit breaker that trips when the motor overheats and resets automatically after cooling.
The jack extends from 9.84 inches retracted to a full 32 inches, making it one of the tallest options available. This is particularly useful for lifted trucks or trailers with high receiver heights. The carbon steel construction features an anti-rust coating, and the included manual crank ensures you are never stranded by a dead battery. Installation is true plug-and-play for most A-frame tongues, with owners reporting 5- to 10-minute installs.
The main trade-off is speed — the powerful motor is deliberate rather than fast, and one owner reported it barely raises faster than a cigarette break. The LED lights on some units do not function, and the customer base reports mixed QC. But for sheer capacity and the peace of mind of a 7,500-pound rating, the KYX is the appropriate tool for a heavy trailer.
Why it’s great
- Highest dynamic capacity on this list
- 32-inch total lift covers lifted trucks
- Auto-reset circuit breaker protects motor
Good to know
- Operating speed is noticeably slow
- LED light function is inconsistent
5. POLESTAR Electric Trailer Jack 3500
The POLESTAR 3500 bridges the gap between affordable entry-level jacks and premium units by offering a generous 31.5-inch total lift (27 inches plus 4.5-inch drop leg) at a mid-range price point. This extra vertical travel is invaluable when parking on uneven terrain or when your tow vehicle sits significantly higher than the trailer coupler. The 12V DC brake motor provides smooth, consistent power without the jutter common in cheaper screw drives.
The LED lights are mounted to shine directly onto the ball and coupler — a small but thoughtful detail for nighttime alignment. The built-in circuit breaker automatically trips if amperage spikes and resets itself once the motor cools. Weighing 22 pounds, the all-steel construction feels substantial, and the powder-coat finish resists corrosion. Multiple height settings let you fine-tune the drop leg to 4.5 inches of additional extension.
Owners upgrading from manual jacks consistently say they regret not making the switch sooner. Installation is straightforward for standard A-frame tongues, and the included waterproof cover extends the jack’s life in rainy climates. A few users note the lack of a visible inline fuse and some initial confusion about grounding. Overall, it is the best option for campers who want maximum height flexibility without breaking into the premium tier.
Why it’s great
- 31.5-inch total lift handles steep terrain
- LEDs aimed directly at the hitch ball
- Quiet brake motor operation
Good to know
- No visible inline fuse included
- Grounding instructions could be clearer
6. Pafessa C24-3312 Electric Tongue Jack
The Pafessa C24-3312 stands out for its integrated 7-pin plug — a major convenience if your trailer already uses a 7-pin connector, as it eliminates the need for separate hard-wiring to the battery. The 150W motor uses an Acme threaded rod and helical steel gears for quieter operation than many similarly priced units. Operating speed measures 0.4 inches per second, meaning an 18-inch cycle completes in about 45 seconds.
The quick-drop footpad adds 4.5 inches of extension, and the 6-inch diameter footplate provides stable footing on soft ground. Dual LED “site-lites” on the die-cast aluminum cap illuminate the coupler area, while the rocker switch is positioned on top for easy one-handed use. A 30-amp circuit breaker protects the RV circuit by cutting power automatically if current exceeds 30 amps, with an emergency hand crank socket accessible from the top.
Some owners note the jack is slow under load and the included mounting hardware can be incomplete (the crank handle socket may be missing in the box). One unit failed intermittently after three months, though most users find the build quality acceptable for the price. Its 7-pin compatibility is a genuine differentiator for those who want to skip the wiring step entirely.
Why it’s great
- Integrated 7-way plug simplifies installation
- 30A circuit breaker prevents overload
- Top-access emergency crank socket
Good to know
- Crank socket not always included in the box
- Operation is slower than premium models
7. Kohree Electric Trailer Jack 4000lbs
The Kohree 4000-lb jack prioritizes speed without sacrificing load capacity. Its 12V DC motor lifts 8 inches in approximately 47 seconds — roughly half the time of many competitors — making it ideal for frequent hook-ups where every minute matters. The dynamic load rating of 4,000 pounds (6,000-pound static) provides a comfortable safety margin for 28-foot travel trailers and pop-up campers.
The 5-gear adjustable drop leg adds 8 inches of extension, and the powder-coated steel construction includes a weatherproof cover that protects the motor from rain and road spray. Dual LED lights flank the coupler for nighttime visibility. The internal circuit breaker disconnects automatically on overload and reconnects after two minutes of cool-down — a simple but effective protection scheme.
A slight caveat: operation is quiet under light to moderate loads but becomes audible when working near the 4,000-pound limit. The included manual crank handle works as a backup. A few users found the wiring instructions ambiguous about the inline fuse (the unit does not require one thanks to the internal breaker, but the reset behavior may confuse first-time installers). At this price point, the speed advantage alone justifies the purchase for active campers.
Why it’s great
- Significantly faster lift than category average
- Internal circuit breaker with auto-reset
- Bonus weatherproof cover included
Good to know
- Gets louder under maximum load
- Wiring instructions could be more detailed
8. RVMATE Electric A-Frame Trailer Jack
For campers on a tighter budget who refuse to go back to hand-cranking, the RVMATE electric jack delivers a solid 3,500- to 4,000-pound capacity at a very accessible price. The 12V motor and spur gear drive raise the trailer smoothly, and the 18-inch stroke with a fully retracted height of 9 inches is standard for most A-frame mounts. The 5.625-inch drop leg adds useful extra reach on uneven ground.
The heavy-duty steel construction features a powder-coated outer tube and a zinc-plated inner tube to resist rust. A built-in fuse protects the electrical system, and a manual crank handle is included for emergencies. The LED lights are a welcome addition for dusk hookups, and the removable footplate is easy to clean. Most owners report a 20-30 minute installation using the included hardware.
Noise levels are better than expected — the gear drive is audible under load but not intrusive. The primary weaknesses are the plastic component quality (the control cap can crack if the box is mishandled) and the 10.5-kilogram weight. A few units arrived with damaged packaging and missing plastic covers, but the seller has a responsive replacement program. For someone looking to electrify a pop-up or lightweight travel trailer, this is the least-expensive entry point with real reliability.
Why it’s great
- Reliable operation at a low cost of entry
- LED lights and manual crank included
- Corrosion-resistant finish on inner/outer tubes
Good to know
- Plastic cap can break if box is crushed
- Heavier than some comparable models
9. Libra 3500lbs Electric Power Jack
The Libra 3500 is the slim-profile alternative for tight A-frame spaces where a bulky motor housing won’t fit. Its one-piece motor cover and stainless steel external hardware (screws, bolts) are rust-proof, addressing a common failure point on cheaper jacks. The 8-inch, 5-step adjustable drop leg combined with a 14-inch screw stroke gives 22 inches of total lift, with an oversized 5.5-inch footplate that has drainage holes to prevent water pooling.
The 12V motor is rated to lift 3,500 pounds dynamically, and the manufacturer claims 20% faster stroke than earlier models. An emergency detachable hand crank is included, and the bright LED light aids night operation. The powder-coated outer tube and zinc-plated inner tube are both treated for rust resistance. Owners report daily use on horse trailers for three years before needing a switch replacement — decent longevity for the price tier.
The leg drop mechanism can spin freely if not secured (one owner reported the leg dropping while driving), and the rocker switch may fail over time. The 55-inch power cord is convenient for most tongue layouts. If you need a compact, corrosion-resistant unit for a pop-up camper or horse trailer, the Libra fits the bill without the bulk of all-steel competition.
Why it’s great
- Slim motor cover fits tight A-frame spaces
- Stainless steel hardware resists rust
- Dual corrosion-resistant tube finish
Good to know
- Drop leg can rotate if not pinned
- Rocker switch may need replacement over time
