A strong automatic trailer jack combines an electric lift with a capacity suited to the trailer’s tongue load, making setup easier for RV, boat, and utility-trailer owners. This roundup compares 10 electric jacks, from 3,500-pound models to options listed at 7,500 pounds, with differences in materials, mounting style, and included accessories. The POLESTAR 7500lb Jack leads for its high listed capacity, alloy-steel construction, and included crank and waterproof cover.
Other picks bring a wireless remote, a lower capacity for lighter setups, or a side-mount configuration. Before choosing, confirm your trailer’s mounting arrangement and the load the jack must handle; advertised capacity alone does not establish compatibility or the full weight supported at the tongue.
The POLESTAR 7500lb Jack is the best overall choice in this group for buyers seeking an automatic jack for an A-frame trailer. Its listed 7,500-pound capacity is the highest among the conventional A-frame options here, and the alloy-steel jack includes a crank and waterproof cover. It also lists compatibility with RVs and trailers.
Check your trailer’s mounting fit and required tongue load before buying, and keep the crank available as a manual backup.

Detailed Reviews: Best Automatic Jack For Trailer

#1 · Best Overall
1. POLESTAR 7500lb Jack
- Load Capacity: 7500 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: RV, Trailer, Truck
Best for: Higher-rated A-frame lifting.
Why it ranks #1: Its 7,500-pound capacity, alloy-steel construction, and included crank and waterproof cover make it a well-equipped choice for RV and trailer use.
A 7,500-pound dynamic rating and 10,000-pound stated static lifting power distinguish this POLESTAR from its lower-capacity sibling. Electric A-frame lifting serves trailers, RVs, boats, and off-road vehicles according to the listing, while an included crank provides a manual operating alternative for this alloy-steel jack.
The dynamic and static figures describe different stated capacities, so buyers should compare the 7,500-pound dynamic load rating with their intended use rather than treating the numbers as interchangeable. Alloy-steel construction supports a heavy-duty trailer accessory, and compatibility is listed for RVs, trailers, and trucks. Its 32.28-inch dimension gives an installation-height reference. The included waterproof cover and crank add protective storage and a manual option alongside electric operation.
- 7,500-pound dynamic load rating
- 10,000-pound stated static lifting power
- Alloy-steel construction
- Includes crank and waterproof cover
- Its 32.28-inch listed dimension may constrain installations with limited vertical clearance.
Skip it if you need a jack shorter than the listed 32.28-inch dimension; check another model's published dimensions before choosing.
This suits owners of heavier A-frame trailer, RV, boat, or truck setups that need the listed 7,500-pound dynamic rating. Allow for its 32.28-inch dimension and distinguish dynamic capacity from the static figure.

#2 · Best Remote Control
2. KYX 7500lb Remote Jack
- Load Capacity: lb 7500
- Material: Alloy Steel
- Compatible with Vehicle Type: RV
Best for: Remote-operated trailer setup.
Why it ranks #2: The 7,500-pound jack includes wireless operation with a stated maximum range of 30 meters, plus a crank handle and cover.
A wireless remote with a stated 30-meter range lets you raise or lower this KYX jack from beside the vehicle or the driver's seat. That reach can help when positioning yourself matters, including the listed uneven-surface, rainy-day, and nighttime situations, while the included crank provides another operating option.
The 7,500-pound load rating and motor-driven height adjustment target RV owners who want powered lifting rather than manual hydraulic operation. Remote control can keep operation accessible without bending over or standing beside the jack, and the 30-meter maximum range gives placement flexibility. The alloy-steel construction and included cover round out the supplied details for an RV installation. A hand crank is also included, giving you a manual option alongside remote operation.
- Wireless remote operation
- Remote range up to 30 meters
- 7,500-pound load capacity
- Includes hand crank and cover
- Remote operation depends on the included wireless controller; no wired control is specified.
Skip it if you prefer a supplied 12V motor specification and anti-rust coating; KYX's other 7500-pound model lists both.
This suits RV owners who value remote operation while positioning a trailer, especially where reaching the jack is inconvenient. Its 7,500-pound rating and alloy-steel body are key selection details; verify that remote operation fits your preferred workflow.

#3 · Best Midrange Capacity
3. POLESTAR 5000lb Jack
- Load Capacity: 5000 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: RV, Trailer, Truck
Best for: Higher-capacity trailer lifting.
Why it ranks #3: Its 5,000-pound capacity suits buyers who do not need the top listed rating, and it includes an alloy-steel body, crank, and waterproof cover.
A 5,000-pound dynamic rating paired with 7,500 pounds of stated static lifting power gives the POLESTAR a clear role with heavier trailer setups. Its electric A-frame operation handles raising and lowering, while the included crank offers a manual option when you need a different way to operate the jack.
The alloy-steel construction and 5,000-pound dynamic load rating suit buyers comparing electric jacks for trailers, RVs, boats, or trucks, all listed compatible vehicle types. The 7,500-pound static lifting figure is distinct from the dynamic rating, so use each in its stated context. At 32.28 inches tall, it has a defined installation profile to check against the trailer. The included waterproof cover and crank provide storage protection and an alternative operating method.
- 5,000-pound dynamic load rating
- 7,500-pound stated static lifting power
- Alloy-steel construction
- Includes crank and waterproof cover
- Its 5,000-pound dynamic rating is lower than the listed 7,500-pound models.
Skip it if you need a listed dynamic rating above 5,000 pounds; this model's capacity stops at that figure.
Choose it for an A-frame trailer, RV, boat, or truck setup within its 5,000-pound dynamic rating. The included crank and cover add practical options, but check the jack's 32.28-inch height against your installation space.

#4 · Best Included Hardware
4. Lippert 3500lb Tongue Jack
- Load Capacity: 3500 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: Trailer
Best for: Lower-capacity Lippert option.
Why it ranks #4: The 3,500-pound electric jack includes a clevis pin, foot pad, cotter pin, and hand crank, with listed compatibility for trailers.
Lippert's stated 3,500-pound lift capacity puts this electric tongue jack in a lower-capacity class than the 7,500-pound choices in this roundup. The supplied description also identifies quiet, efficient helical-cut gears and easy installation, giving trailer owners specific reasons to consider its operating character and setup approach.
The 3,500-pound rating provides a concrete capacity boundary for trailer selection, while the alloy-steel construction identifies the jack's material. Lippert describes helical-cut gears as quiet and efficient, a useful operating detail for buyers who prefer powered lifting without the sound of a hand crank. Included hardware comprises a clevis pin, foot pad, hairpin cotter pin, and hand crank, which gives installers several listed mounting and operation components in the package.
- 3,500-pound lift capacity
- Helical-cut gears described as quiet and efficient
- Alloy-steel construction
- Includes clevis pin, foot pad, cotter pin, and hand crank
- Its 3,500-pound capacity is below the 4,000-pound models listed here.
Skip it if you need a rating above 3,500 pounds; the Kohree HY1711-KO-US-FBA-2 lists a 4,000-pound capacity.
This is a fit for trailer owners whose requirements fall within its 3,500-pound lift capacity and who value the stated helical-gear operation. Check the trailer's needs against that limit before choosing this Lippert jack.

5. VEVOR 4000lb Electric Jack
- Load Capacity: 4000 lb
- Material: Carbon Steel
- Compatible with Vehicle Type: Trailer
Best for: Weather-exposed 4000-pound trailers.
Why it ranks #5: This 4,000-pound carbon-steel model includes a crank handle and waterproof cover, and its listed 2-year manufacturer warranty is longer than most here.
A 4,000-pound capacity and carbon-steel body with a protective coating give the VEVOR jack a defined place in everyday trailer lifting. The listing calls out RV, horse, utility, and yacht trailers, while the included waterproof sunshade cover offers a storage and exposure-related accessory for those setups.
The stated 9.84-to-33.85-inch range provides a height reference for buyers checking the jack against their trailer arrangement. Its carbon steel has a protective coating specified to withstand splashes and tough outdoor conditions, supporting use around exposed towing equipment. The 4,000-pound capacity sets the lifting boundary, and the included crank handle gives an alternative operating method. A waterproof sunshade cover is also supplied, so the package includes a named protective accessory.
- 4,000-pound load capacity
- 9.84-to-33.85-inch stated height range
- Coated carbon-steel construction
- Includes crank handle and waterproof sunshade cover
- Its 4,000-pound capacity is below the 5,000-pound POLESTAR 10201091 rating.
Skip it if you need more than 4,000 pounds of capacity; the POLESTAR 10201091 lists a 5,000-pound dynamic rating.
Pick this for a compatible RV, horse, utility, or yacht trailer within the 4,000-pound rating, especially if the included cover and crank suit your routine. Its stated height range is a practical fit check.

6. Kohree 4000lb Tongue Jack
- Load Capacity: 4000 lb
- Material: Heavy-duty steel with anti-rust coating
- Compatible with Vehicle Type: Camper, RV, Trailer
Best for: Quick 4000-pound A-frame lifting.
Why it ranks #6: Its 4,000-pound dynamic and 6,000-pound static capacities are specified separately, and the package includes wiring, a cover, crank handle, and mounting bolts.
Kohree states that its jack lifts eight inches in 47 seconds, giving buyers a concrete operating-time figure for a 4,000-pound A-frame model. Its 12V DC motor powers raising and lowering, and the listing provides a static lifting figure of 6,000 pounds alongside the 4,000-pound dynamic rating.
The 4,000-pound dynamic and 6,000-pound static figures give separate capacity references for RV, camper, and trailer owners. A stated 47-second lift for eight inches helps set expectations for powered adjustment, while the 12V motor operates by button. Heavy-duty steel with an anti-rust coating provides the specified material protection. The package includes a cover, manual crank handle, and three mounting bolts, supporting installation and an alternate manual method.
- 4,000-pound dynamic load and 6,000-pound static lifting ratings
- 12V DC motor with button operation
- Stated eight-inch lift time of 47 seconds
- Includes cover, manual crank handle, and three mounting bolts
- Its 4,000-pound dynamic rating is lower than the 5,000-pound POLESTAR 10201091.
Skip it if you need more than 4,000 pounds of dynamic capacity; the POLESTAR 10201091 lists a 5,000-pound dynamic rating.
This suits camper, RV, and trailer owners with needs within its 4,000-pound dynamic rating who value the stated lift time and included crank. Check the installation against its listed A-frame format.

7. Pafessa 3500lb Tongue Jack
- Load Capacity: 3500 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: RV, Trailer
Best for: A-frame lift-range flexibility.
Why it ranks #7: This A-frame model lists 18 inches of travel, a footpad adding 4.5 inches, and mounting hardware, but its emergency crank driver is not included.
Eighteen inches of travel plus a drop foot that adds 4.5 inches of extension gives the Pafessa jack a defined height-adjustment advantage. Its 3,500-pound rating and stated compatibility with 2.25-inch mounting holes target many A-frame trailers and RVs, while the LED light supports visibility during operation.
The 18-inch travel and adjustable six-inch-diameter footpad, which adds 4.5 inches of extension, provide two listed dimensions to consider when matching the jack to trailer height. A 3,500-pound lift and tongue-weight capacity sets the stated limit. The seven-foot power cord uses positive and negative wires for direct grounding, with terminals not included. Mounting hardware and a weather-resistant cover are supplied, and the emergency crank socket requires a separate driver handle.
- 18 inches of travel plus 4.5-inch drop-foot extension
- 6-inch-diameter adjustable footpad
- Fits 2.25-inch mounting holes on most A-frame trailers and RVs
- Includes mounting hardware and weather-resistant cover
- The emergency crank socket is supplied without its driver handle.
Skip it if you need an emergency crank handle included; this package lists the socket but says the driver handle is not included.
Choose this for an A-frame trailer or RV with compatible mounting holes and a 3,500-pound requirement, especially when its travel and drop-foot extension suit your setup. Plan separately for wire terminals and the crank driver handle.

8. SEALIGHT 7500lb Jack
- Load Capacity: 7500 lb
- Material: Carbon Steel
- Compatible with Vehicle Type: RV
Best for: Nighttime 7500-pound lifting.
Why it ranks #8: Its listed 7,500-pound capacity, LED lights, and built-in circuit breaker are useful features, though the supplied details identify only a housing as included.
LED lights for nighttime lifting and a built-in circuit breaker give the SEALIGHT jack two operation-focused features alongside its 7,500-pound rating. The 12V DC motor is described as supporting quick lifting, while its carbon-steel construction and stated RV compatibility identify the intended trailer context.
The 7,500-pound load capacity and 12V DC motor point to powered lifting for an RV setup, and the listing describes the lift function as quick. LED lights improve visibility during nighttime lifting operations, a practical aid when working after dark. The built-in circuit breaker automatically cuts power for protection if the jack is improperly operated. Carbon steel is the specified material, and the product is listed as compatible with RVs.
- 7,500-pound load capacity
- 12V DC motor
- LED lights for nighttime lifting
- Built-in circuit breaker with automatic power-off protection
- The listing names only RV compatibility, limiting the stated vehicle fit information.
Skip it if you need compatibility explicitly listed for a boat or yacht trailer; FZZD's Electric Trailer Jack 5500lbs lists both.
Consider this for an RV owner who wants a 7,500-pound electric jack with lighting for after-dark lifting and circuit-breaker protection. Its stated compatibility is RV-only, so keep that boundary in mind when selecting.

9. KYX 7500lb Electric Jack
- Load Capacity: 7500 LB
- Material: Carbon Steel
- Compatible with Vehicle Type: RV, Trailer
Best for: Coated-steel 7500-pound jack.
Why it ranks #9: It offers a 7,500-pound capacity and carbon-steel construction with an anti-rust coating, but the supplied component list does not specify included accessories.
A 12V DC motor rated for a 7,500-pound load gives this KYX electric jack powered lifting for A-frame trailers. Its carbon-steel body has an anti-rust coating, a material treatment the supplied description says resists harsh outdoor conditions and water splashes, making weather exposure a relevant part of its appeal.
The 12V DC motor raises or lowers an A-frame trailer, replacing manual lifting during routine setup, while the 7,500-pound load rating identifies its stated capacity. Carbon steel with an anti-rust surface coating is specified to resist outdoor conditions and water splashes, supporting use around the elements. It is listed as compatible with RVs and trailers. The product data does not list included components, so buyers should account for that when planning installation or operation.
- 12V DC motor
- 7,500-pound load capacity
- For A-frame trailers
- Carbon steel with anti-rust coating
- Included components are listed as unspecified, leaving supplied installation accessories unclear.
Skip it if you want listed accessories such as a crank and waterproof cover; the POLESTAR 7500-pound model includes both.
Consider this for an RV or trailer owner seeking 12V-powered A-frame lifting at a 7,500-pound rating. Its coated carbon-steel construction suits outdoor exposure, but the unspecified included components make accessory planning important.

#10 · Best Side-Mount Option
10. FZZD 5500lb Side-Mount Jack
- Load Capacity: 5500 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: Boat Trailer, RV, Yacht Trailer
Best for: Long-travel A-frame lifting.
Why it ranks #10: Its 5,500-pound lifting rating and 22.6-inch vertical travel are notable, but its side-mount design is a less direct fit for typical A-frame jack searches.
A stated 22.6 inches of vertical travel and a 3-to-26.2-inch lifting range give this FZZD jack notable height figures for trailer setup. Its one-button 12V DC operation and 5,500-pound lifting rating target buyers seeking powered adjustment, while the built-in auto-resetting circuit breaker addresses overload or short-circuit protection.
The 5,500-pound lifting capacity and 7,500-pound support capacity are separately stated, helping buyers distinguish the jack's listed functions. Four-level height adjustment and a 3-to-26.2-inch lifting range offer defined positioning choices, while one-button operation controls the 12V DC motor. The auto-resetting circuit breaker cuts power during overload or a short circuit to protect the motor. A drop leg is included, and compatibility lists boat trailers, RVs, and yacht trailers.
- 5,500-pound lifting and 7,500-pound support capacities
- 22.6 inches of stated vertical travel
- Four-level height adjustment
- Auto-resetting circuit breaker
- The listing specifies a side-mount style, which may not suit every mounting arrangement.
Skip it if you need a mount other than the listed side-mount style; verify your trailer's mounting arrangement before selecting this jack.
This fits boat, RV, or yacht trailer owners who can use its side-mount style and want the stated long travel and motor protection. Compare its lifting and support ratings separately with your setup.

View on AmazonAvoid a mounting-style mismatch
A jack’s mounting style can matter as much as its capacity, so confirm the trailer’s jack location and mounting plate before choosing. Most products here are described as A-frame or tongue jacks, including the POLESTAR, KYX, Lippert, VEVOR, and Kohree options. The FZZD listing explicitly identifies a side-mount design, which may not match an A-frame trailer’s existing mounting point even though it is marketed for trailer use.
The Pafessa listing specifies 2.25-inch mounting holes on most A-frame trailers, but that detail should still be checked against your own plate. Product titles and broad vehicle compatibility do not establish bolt pattern, clearance, or wiring fit.
If the mounting configuration differs, you may need a compatible installation arrangement; do not treat a higher capacity as a substitute for confirming physical fit.
Plan for power loss before it happens
An electric jack can become unusable when its power supply or electrical system fails, so retain a practical manual fallback. Several listings include a hand crank or crank handle, including the POLESTAR models, KYX remote model, VEVOR, and Kohree. The Pafessa package lists an emergency crank socket but says the driver handle is not included, so verify what tool you need before relying on it.
The Lippert package also lists a hand crank. These details do not establish that a crank will solve every electrical or mechanical failure, but they provide a manual operating option when available and usable.
Remote operation adds convenience, as on the KYX 7500lb Remote Jack, but it does not replace the need to understand the jack’s manual procedure. Check the product instructions and keep the required crank or tool accessible.
How to Choose an Automatic Trailer Jack
Capacity and the load it represents
Choose a listed capacity that suits the load your jack must lift, and verify whether the manufacturer describes it as lifting, dynamic, or support capacity. Ratings in this group range from 3,500 pounds on the Lippert and Pafessa models to 7,500 pounds on several options. POLESTAR lists 5,000-pound dynamic capacity and 7,500-pound static lifting power for its 5,000-pound model; Kohree separately lists 4,000-pound dynamic and 6,000-pound static capacity.
These figures are not interchangeable, and a trailer’s total weight alone does not tell you the tongue load. A lighter setup may favour a 3,500- or 4,000-pound model, while buyers who need a higher listed rating can consider the 7,500-pound options after checking their actual requirements.
Mounting configuration and fit
Match the jack’s mounting arrangement to your trailer before prioritizing capacity or extras. Many models in this roundup are described as A-frame or tongue jacks; the Pafessa listing specifically says it fits 2.25-inch mounting holes on most A-frame trailers. By contrast, the FZZD is explicitly a side-mount jack, so it is the clearest option for a buyer whose trailer requires that configuration, but a potential mismatch for a typical A-frame installation.
The listings do not provide a complete shared set of bolt-pattern or clearance measurements. A-frame owners should compare their mounting plate and available space with the product details, while side-mount buyers should verify attachment points and clearance before ordering.
Accessories and backup operation
Look at the included components and control method, especially if you want a backup way to operate the jack. The POLESTAR 7500lb Jack includes a crank and waterproof cover; the KYX 7500lb Remote Jack adds wireless control with a stated maximum range of 30 meters and also lists a crank handle and cover. VEVOR includes a crank handle and cover, while Kohree lists a manual crank handle, wiring, and mounting bolts.
Pafessa includes an emergency crank socket, but its driver handle is not included. Buyers who value remote operation may prefer KYX, while those who want specified manual backup hardware should compare the included parts carefully.
Check the package list for the exact accessories rather than assuming every electric jack includes the same items.
Which Automatic Trailer Jack Should You Choose?
For a higher-capacity A-frame choice with a crank and cover included, choose the POLESTAR 7500lb Jack. If operating the jack remotely is your priority, the KYX 7500lb Remote Jack lists wireless control up to 30 meters and includes a crank handle and cover. For a midrange 5,000-pound rating, the POLESTAR 5000lb Jack offers alloy-steel construction and the same listed backup crank and cover.
Lighter-duty buyers can consider the Lippert 3500lb Tongue Jack or VEVOR 4000lb Electric Jack, depending on required capacity and included gear. Choose the FZZD 5500lb Side-Mount Jack only if its side-mount arrangement suits your trailer.
In every case, verify the required tongue load, mounting fit, and electrical connection before selecting a model.

Frequently Asked Questions
How do I determine the tongue load my trailer jack needs to support?
Check your trailer manufacturer’s information for its tongue load, then select a jack with a listed capacity that meets or exceeds that requirement. Do not use the trailer’s total weight as a substitute for tongue load. If the needed figure is unclear, ask the trailer manufacturer or a qualified service professional before choosing.
How can I confirm an electric jack will fit my trailer’s mounting plate and wiring?
Compare the jack’s mounting arrangement with your trailer’s mounting plate, and check the product information for fit details. Confirm that the electrical connection is compatible with your trailer before buying. If either fit or wiring is uncertain, consult the jack or trailer manufacturer rather than assuming the installation will work.
What should I do if an electric trailer jack loses power while the trailer is hitched?
Keep the trailer stable and do not work beneath a trailer supported only by the jack. If the jack includes a manual crank, use it according to the product instructions; some listed options include one. If there is no crank or the jack will not operate safely, consult its manual or contact a qualified service professional.
When should I choose a side-mount jack instead of an A-frame jack?
Choose a side-mount jack only when that arrangement suits your trailer’s mounting location and structure. The listed side-mount option should not be treated as interchangeable with an A-frame jack. Check the trailer’s mounting setup and the jack’s fit information before selecting either style.
Is a remote-control jack the right choice for every buyer?
Not necessarily. A remote may be useful if operating the jack remotely is a priority; the listed remote option specifies wireless control up to 30 meters. If remote operation is not important, compare capacity, mounting fit, electrical connection, and included backup gear instead, and keep any supplied manual crank available.
Final Words
For an A-frame trailer, the POLESTAR 7500lb Jack is the strongest overall fit in this group based on its listed capacity, crank, and waterproof cover. Choose the KYX remote model if remote operation matters, or consider the 5000-pound POLESTAR for a lower listed capacity. Lighter-duty options may suit lower tongue loads.
Before deciding, verify tongue load, mounting fit, and electrical compatibility, and keep a manual backup option available.
