A strong electric tongue jack should match your trailer’s tongue load, mounting arrangement, and required lift range, while making hookup and leveling easier for RV and trailer owners. The products here range from 3,500-pound models to options rated at 7,600 pounds, with differences in controls, travel, and included accessories. POLESTAR’s 5,000-pound jack leads for its stated capacity, A-frame design, and included crank and waterproof cover.
Other picks stand out for specific needs, including remote operation, a 7-way connector, or a high stated capacity. Before choosing, check the trailer maker’s tongue-weight guidance and confirm the jack’s mounting dimensions and wiring match your trailer; advertised load capacity alone does not establish compatibility.
The POLESTAR 5000lb Electric Trailer Jack is the best overall fit in this lineup for buyers seeking an A-frame electric tongue jack. It lists a 5,000-pound dynamic load capacity, alloy-steel construction, and compatibility with RVs, trailers, and trucks. Its included crank and waterproof cover add useful backup and protection components.
Choose it when those specifications suit your trailer; confirm mounting fit and required lift range before ordering, since the supplied product data does not give its travel measurement.

#1 · Best Overall
1. POLESTAR 5000lb Jack
- Load Capacity: 5000 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: RV, Trailer, Truck
- Weight: 21.7 lb
Best for: Heavy A-frame trailer lifter.
Why it ranks #1: Its 5,000-pound dynamic capacity, A-frame design, RV and trailer compatibility, and included crank and waterproof cover make a well-rounded match.
A 5,000-pound dynamic load rating gives the POLESTAR jack capacity for lifting many trailers, RVs, boats, and off-road vehicles. Its alloy-steel construction and included crank make it a substantial A-frame option for owners who want powered lifting with a manual backup available in the package.
The 5,000-pound dynamic rating addresses demanding trailer-lifting needs, while the stated 7,500-pound static lifting power provides a separate capacity figure for stationary support. Alloy steel is the listed construction material, and the included crank gives the package a manual operating option alongside the electric jack. A waterproof cover is also included, which supports covered storage between trips. Its listed vehicle compatibility includes RVs, trailers, and trucks, so it suits buyers whose equipment falls within those categories and the capacity limits.
- 5,000-pound dynamic load capacity
- 7,500-pound stated static lifting power
- Alloy-steel construction
- Includes crank and waterproof cover
- No operating travel, lighting, or remote-control details are supplied.

#2 · Best LED Lighting
2. Lippert 3500lb Jack
- Load Capacity: 3500 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: Trailer
- Weight: 28.6 lb
Best for: LED-lit 3,500-pound lifting.
Why it ranks #2: This 3,500-pound trailer jack includes a hand crank and foot pad, while its description specifies four integrated LED lights and helical-cut gears.
Four integrated LED lights give the Lippert 3,500-pound electric tongue jack a useful visibility feature for hookup and lifting work. Its helical-cut gears are described as quiet and efficient, pairing powered operation with a more considered working sound for trailer owners.
The 3,500-pound lift capacity sets the load boundary, while four integrated LED lights support visibility around the jack during setup. Lippert specifies quiet, efficient helical-cut gears, a practical feature for buyers who want powered lifting without the description of a noisier gear system. The package includes a 5-3/8-inch foot pad, clevis pin, hairpin cotter pin, and hand crank, providing core mounting and manual-operation components. Compatibility is listed for trailers.
- 3,500-pound load capacity
- Four integrated LED lights
- Quiet, efficient helical-cut gears
- Includes foot pad, pins, and hand crank
- Listed vehicle compatibility is limited to trailers.
Skip it if you need a stated load rating above 3,500 pounds; the Kohree 5000-pound A-frame jack lists greater capacity.
The Lippert is a fit for trailer owners seeking a 3,500-pound electric jack with integrated lighting, specified gear operation, and included mounting components. Keep its trailer-only listed compatibility and capacity in mind when selecting an installation.

3. Kohree 5000lb Jack
- Load Capacity: 5000 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: Camper, RV, Trailer
- Weight: 21.2 lb
Best for: Wired 5,000-pound A-frame jack.
Why it ranks #3: Its 5,000-pound capacity suits many trailer setups, and the package lists a manual crank, cover, and three mounting bolts.
A 5,000-pound dynamic rating with 7,500 pounds of stated static lifting power gives the Kohree jack clear capacity figures for A-frame trailer owners. Its 12V DC motor and push-button operation make powered raising and lowering the central workflow, with two LED lights also specified.
The 12V DC motor and push-button controls support powered lifting and lowering, while the 5,000-pound dynamic rating defines its stated working capacity. Kohree also lists 7,500 pounds of static lifting power. Two LED lights add visibility around the jack, and the package includes a manual crank for an alternate operating method, a cover, and three mounting bolts. Listed compatibility includes campers, RVs, and trailers, making it a broad fit within the supplied categories.
- 5,000-pound dynamic load capacity
- 7,500-pound stated static lifting power
- Two LED lights
- Includes manual crank, cover, and three mounting bolts
- No travel range or remote-control feature is specified.
Skip it if you need a wireless remote for operation away from the jack; the KYX 7500-pound RV jack lists a 30-meter remote.
The Kohree suits camper, RV, and trailer owners seeking push-button A-frame lifting with lights and a manual crank included. Its capacity and installation details should match the specific trailer, especially if a defined travel range matters.

#4 · Best Travel Range
4. Pafessa 3500lb Jack
- Load Capacity: 3500 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: RV, Trailer
- Weight: 8 kg
Best for: A-frame range flexibility.
Why it ranks #4: The 3,500-pound A-frame model specifies 18 inches of travel plus 4.5 inches from its adjustable footpad, with a cover included.
An 18-inch travel range plus a footpad that adds 4.5 inches gives the Pafessa jack extra height adjustment for trailer setup. Its 3,500-pound capacity and stated fit for 2.25-inch mounting holes make it a practical candidate for compatible A-frame trailers and RVs.
The 18 inches of jack travel combines with the adjustable, 6-inch-diameter footpad's additional 4.5-inch extension, giving buyers two listed ways to adjust reach at a campsite or hookup. Its 3,500-pound lift capacity defines the load limit to consider. The seven-foot power cord uses positive and negative wires for direct grounding; wire terminals are not included, so installation requires accounting for that detail. A weather-resistant cover and mounting hardware come in the package.
- 3,500-pound lift capacity
- 18 inches of travel with 4.5-inch footpad extension
- 6-inch adjustable footpad
- Includes weather-resistant cover and mounting hardware
- Wire terminals are not included with the seven-foot power cord.
Skip it if you need more than 3,500 pounds of lift capacity; the SEALIGHT 7500-pound jack lists a higher capacity.
This Pafessa suits an A-frame trailer or RV with compatible 2.25-inch mounting holes and a load within its rating. Its travel and extension offer adjustment flexibility, but plan separately for the missing wire terminals.

#5 · Highest Stated Capacity
5. POLESTAR 7500lb Jack
- Load Capacity: 7500 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: RV, Trailer, Truck
- Weight: 23.9 lb
Best for: High-capacity A-frame choice.
Why it ranks #5: It lists a 7,500-pound dynamic capacity and compatibility with RVs and trailers, plus an included crank and waterproof cover.
A 7,500-pound dynamic rating and 10,000-pound static lifting figure make this POLESTAR the higher-capacity sibling in its lineup. Its alloy-steel construction and included crank and waterproof cover support buyers seeking a substantial electric jack with manual operation and covered storage accounted for.
The stated 7,500-pound dynamic capacity is paired with 10,000 pounds of static lifting power, giving buyers two distinct ratings to consider for their trailer setup. The jack is listed for RVs, trailers, and trucks, and alloy steel is its specified material. An included crank provides a manual operating option, while the waterproof cover supports storage protection when the jack is not in use. The supplied details do not state travel range, lighting, or remote operation.
- 7,500-pound dynamic load capacity
- 10,000-pound stated static lifting power
- Alloy-steel construction
- Includes crank and waterproof cover
- No travel range, lighting, or remote-operation details are supplied.
Skip it if you need specified LED lighting or a travel range; the FZZD 5500-7500-pound model lists a 22.6-inch vertical travel.
Choose this POLESTAR when your RV, trailer, or truck setup calls for its stated high load capacity and you value an included crank and waterproof cover. Consider the missing travel details when planning installation and reach.

6. SEALIGHT 7500lb Jack
- Load Capacity: 7500 lb
- Material: Carbon Steel
- Compatible with Vehicle Type: RV
Best for: Higher-capacity RV lifting.
Why it ranks #6: Its 7,500-pound capacity, 12V DC motor, LED lights, and built-in circuit breaker suit buyers prioritizing capacity and listed safety features.
A 7,500-pound load capacity is the defining feature of this SEALIGHT jack, giving RV owners a higher stated lifting rating than many 3,500-pound options. Its 12V DC motor supports powered operation, while built-in LED lights address visibility during nighttime lifting tasks.
The 12V DC motor and 7,500-pound capacity combine powered lifting with a substantial stated load rating for RV use. LED lights are specified to improve visibility during nighttime operations, which can help when setting up after dark. A built-in circuit breaker automatically cuts power if the jack is improperly operated, adding a listed protection feature to the operating workflow. The supplied information identifies RV compatibility and includes housing, but gives no travel range or mounting dimensions.
- 7,500-pound load capacity
- 12V DC motor
- LED lights for nighttime visibility
- Built-in circuit breaker power-off protection
- The supplied specifications list RV compatibility only, not broader vehicle types.
Skip it if you need listed compatibility with boats, trucks, or trailers beyond RVs; the POLESTAR 7500-pound model names RVs, trailers, and trucks.
Consider this SEALIGHT for RV lifting when its 7,500-pound rating, nighttime lighting, and circuit-breaker protection match your priorities. The supplied details do not state travel or mounting dimensions, so those specifics may affect installation planning.

7. KYX 7500lb Remote Jack
- Load Capacity: lb 7500
- Material: Alloy Steel
- Compatible with Vehicle Type: RV
Best for: Remote-operated RV jack.
Why it ranks #7: The 7,500-pound model includes wireless remote operation with a stated 30-meter maximum range, plus a hand crank and cover.
A wireless remote with a maximum stated range of 30 meters lets the KYX jack operate from the driver's seat or beside the vehicle. That convenience pairs with a 7,500-pound capacity for RV owners who want to control lifting without staying at the jack.
Remote operation is the defining workflow advantage: the listed 30-meter maximum range allows control from the driver's seat or nearby, including on uneven surfaces or in rain and at night, as described. The 7,500-pound capacity sets the load boundary, and the motor-driven height adjustment is described as quick and smooth. A cover and hand crank are included, so the package also accounts for covered storage and manual operation. Compatibility is listed for RVs.
- Wireless remote operation up to 30 meters
- 7,500-pound load capacity
- Motor-driven height adjustment
- Includes cover and hand crank
- Listed vehicle compatibility is limited to RVs.
Skip it if you need a 3,500-pound trailer jack with specified LED lighting and gear details; Lippert 285318 lists those features.
The KYX suits RV owners who value remote control from a distance and need capacity within its 7,500-pound rating. Its RV-only listed compatibility and included hand crank are relevant considerations for installation and backup operation.

8. FZZD 7-Way Jack
- Load Capacity: 5500 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: RV
- Weight: 26 lb
Best for: 7-way-connected trailer setups.
Why it ranks #8: This 5,500-pound lifting model specifies a 2.25-inch outer tube and 7-way connector, with a stated lift range from 8.5 to 31.7 inches.
A 7-way connector defines this FZZD jack for buyers seeking a connection-based option for compatible trailer setups. Its 5,500-pound lifting and 7,500-pound support ratings pair with a stated 8.5-to-31.7-inch lift range, giving a wide listed span for different trailer heights.
The 7-way connector is the defining configuration detail, while the industry-standard 2.25-inch outer tube is stated to fit most camper trailers. Its 5,500-pound lifting and 7,500-pound support ratings clarify the listed load figures. The 8.5-to-31.7-inch range covers low-profile and high-clearance trailers, and one-button electric operation supports powered raising and lowering. An auto-resetting circuit breaker is specified to cut power during overload or short circuit; a drop leg is included.
- 7-way connector configuration
- 2.25-inch outer tube stated to fit most camper trailers
- 5,500-pound lifting and 7,500-pound support ratings
- 8.5-to-31.7-inch lift range
- The listed vehicle compatibility is RV, so other vehicle types are not specified.
Skip it if you need listed compatibility with boat or yacht trailers; the FZZD side-mount model names both categories.
Consider this FZZD for an RV or camper trailer where its 7-way connection, 2.25-inch outer tube, and broad stated lift range fit the setup. Its listed RV compatibility is an important boundary for other applications.

9. FZZD 5500lb Jack
- Load Capacity: 5500 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: Boat Trailer, RV, Yacht Trailer
- Weight: 26 lb
Best for: Long-travel height adjustment.
Why it ranks #9: It lists 5,500 pounds of lifting capacity, 22.6 inches of vertical travel, a four-level height adjustment, and a built-in circuit breaker.
A listed 22.6-inch vertical travel range gives this FZZD jack a defined adjustment span for trailer setup. Its 5,500-pound lifting capacity and 7,500-pound support capacity add clear load figures, while one-button 12V DC operation replaces manual raising and lowering during routine hookups.
The 22.6-inch vertical travel and four-level height adjustment address differing tongue heights, with the stated lifting range extending from 3 to 26.2 inches. A 5,500-pound lift rating and 7,500-pound support rating distinguish operating capacity from support capacity. The one-button 12V DC motor simplifies raising and lowering, while an auto-resetting circuit breaker cuts power during overload or short circuit. A drop leg is included, and listed compatibility covers boat trailers, RVs, and yacht trailers.
- 22.6-inch vertical travel
- 5,500-pound lifting and 7,500-pound support ratings
- Four-level height adjustment
- Auto-resetting circuit breaker
- The product is listed as side-mount, which may not suit other mounting arrangements.
Skip it if you need a 7-way connector rather than the listed side-mount style; the FZZD HZ-09-7-Way-N is the connector-specific model.
This FZZD fits buyers needing substantial height adjustment for a boat trailer, RV, or yacht trailer within its load ratings. Its listed side-mount configuration is a key installation consideration before choosing it.

10. Dnigh 7600lb Jack
- Load Capacity: 7600 lb
- Material: Iron-Zinc Alloy
- Compatible with Vehicle Type: RV, Trailer
- Weight: 11.8 kg
Best for: Remote-control high-capacity lifting.
Why it ranks #10: Its 7,600-pound capacity and two remote controls are notable, but the supplied details do not identify an A-frame fit or give travel information.
Two remote controls and a stated 7,600-pound capacity define this Dnigh electric trailer jack for RV and trailer owners. Its title also specifies IP65 waterproofing, pairing remote operation with a named ingress-protection feature for buyers considering exposed trailer use.
The two included remote controls provide the listed control approach, while the 7,600-pound capacity sets the stated load limit for RV and trailer applications. IP65 waterproofing is specified in the title, a relevant feature for buyers considering outdoor use around a trailer. The jack is made from iron-zinc alloy, and its listed dimensions are 3.5 by 3.5 by 30 inches. The supplied information does not describe travel, mounting hardware, or a manual crank.
- 7,600-pound load capacity
- Two remote controls included
- IP65 waterproofing specified
- Iron-zinc alloy construction
- No manual crank or mounting hardware is listed among included components.
Skip it if you need a stated manual crank and included cover; the KYX 7500-pound RV jack lists both.
This Dnigh fits RV and trailer owners who want the stated 7,600-pound capacity, two remotes, and IP65 waterproofing. Check whether its unspecified travel and mounting details meet the needs of your installation.

View on AmazonAvoiding fit and wiring surprises
A jack’s stated capacity does not confirm that it will bolt onto your trailer or connect to its power system. The Pafessa model specifies 2.25-inch mounting holes, while the FZZD 7-Way Jack specifies a 2.25-inch outer tube; these are useful clues, but they describe different fit details and should not be treated as interchangeable. Check the trailer’s mounting plate and the jack’s installation instructions before buying.
Wiring also varies: Pafessa lists a 7-foot power cord with positive and negative wires for direct grounding, while the FZZD connector version is identified as a 7-way model. Do not assume a plug-in jack and a hardwired jack use the same connection.
Confirm the required electrical connection and available power source for the specific product. The data does not provide complete mounting diagrams or connector instructions for every pick, so verify those details with the manufacturer when uncertain.
Plan for power loss before you need it
A manual backup can matter if an electric jack cannot operate, and several products explicitly include a crank or emergency crank socket. The POLESTAR 5000lb Jack, POLESTAR 7500lb Jack, Kohree 5000lb Jack, and Lippert 3500lb Jack list a hand crank; Pafessa includes an emergency crank socket, but its listing says the driver handle is not included. KYX also includes a hand crank.
That difference is worth checking before travel, because a socket without its handle may not provide the same ready-to-use backup. Other listed features address different concerns: SEALIGHT and FZZD specify circuit breakers, while the Lippert description mentions integrated LED lights.
These features do not establish how a jack behaves in every failure, so read the product instructions and keep the specified manual backup accessible. No supplied product data confirms whether a backup crank is easy to use under load.
How to Choose an Electric Trailer Tongue Jack
Capacity and trailer match
Look for a listed capacity that is appropriate for the trailer’s tongue load, not simply its full vehicle weight. The products span 3,500 pounds for the Lippert 3500lb Jack and Pafessa 3500lb Jack, 5,000 pounds for the POLESTAR 5000lb Jack and Kohree 5000lb Jack, and up to 7,600 pounds for the Dnigh 7600lb Jack. Some listings distinguish dynamic and static capacity: POLESTAR states 5,000 pounds dynamic and 7,500 pounds static for its 5,000-pound model.
Compare the relevant rating with your trailer manufacturer’s guidance and avoid assuming ratings are defined identically across listings. Lighter-duty setups may suit a 3,500-pound model; buyers with higher documented tongue loads may prefer a higher-rated option, provided fit also checks out.
Lift travel and foot adjustment
Choose a jack whose stated travel and foot adjustment cover your trailer’s required hookup and leveling height. Pafessa lists 18 inches of travel and an adjustable footpad that adds 4.5 inches. The FZZD 5500lb Jack specifies 22.6 inches of vertical travel and a lifting range of 3 to 26.2 inches, while the FZZD 7-Way Jack gives a range of 8.5 to 31.7 inches.
These figures are not presented in an identical format, so compare the product’s instructions with the actual ground-to-coupler range you need. A buyer dealing with varied parking surfaces may value an adjustable foot or a broader stated range.
If your trailer sits high or low, check the endpoints rather than selecting by capacity alone; several listings do not provide travel measurements.
Controls, connection, and backup parts
Check how each jack is powered and operated, and whether its included parts suit your setup. KYX lists a wireless remote with a maximum range of 30 meters, while the Dnigh 7600lb Jack specifies two remote controls. The FZZD 7-Way Jack is identified by its 7-way connector; Pafessa instead lists a 7-foot cord with positive and negative wires for direct grounding.
Backup components differ too: several models include a hand crank, whereas Pafessa lists an emergency crank socket and says the driver handle is not included. Buyers who want to operate the jack from beside or away from the trailer may favor a remote model.
Those who prefer a conventional connection should verify connector compatibility, and anyone relying on manual backup should confirm the needed handle is supplied.
Which electric tongue jack should you choose?
For a broadly equipped A-frame option, choose the POLESTAR 5000lb Jack: it lists 5,000 pounds of dynamic capacity, RV and trailer compatibility, a crank, and a waterproof cover. If your trailer’s documented needs fit a 3,500-pound rating and lighting matters, the Lippert 3500lb Jack lists four integrated LED lights and includes a hand crank. For a higher listed capacity, consider the POLESTAR 7500lb Jack or SEALIGHT 7500lb Jack; SEALIGHT also specifies a circuit breaker and LED lights.
Choose the KYX 7500lb Remote Jack if remote operation is a priority. For a stated 7-way connection, look at the FZZD 7-Way Jack.
Confirm tongue-load requirements, mounting fit, lift range, and wiring before selecting any model.

Frequently Asked Questions
How do I calculate the tongue-weight capacity my trailer jack needs?
Use the tongue weight of your fully loaded trailer, not its unloaded weight. Check the trailer or hitch documentation, or have the loaded tongue weight measured with suitable equipment. Compare that figure with the jack’s stated capacity and choose a jack rated to handle the load; do not assume trailer gross weight equals tongue weight.
How can I confirm an electric jack will fit my trailer’s mounting plate?
Measure the mounting plate and hole pattern on your trailer, then compare those dimensions with the jack’s installation information. Check the jack’s mounting style and available clearance around the coupler, frame, and nearby equipment. If the product data does not provide the needed dimensions, ask the manufacturer or seller before ordering.
What should I do if the jack loses power while the trailer is hitched?
Keep the trailer secured: chock its wheels and do not disconnect it from the tow vehicle until it is safely supported. Check the power connection and vehicle or battery supply, following the jack’s instructions. Use a manual crank only if the jack includes or supports one; otherwise, consult its manual or qualified assistance.
How much lift travel should I look for?
Measure the vertical movement needed to raise or lower the coupler between your normal towing position and the height required for hitching or leveling. Include the trailer’s stance and the tow vehicle’s hitch height in that check. Compare your measurement with the jack’s stated travel, and confirm it can reach both positions.
What should I check before connecting the jack’s wiring?
Confirm the jack’s specified connector and electrical requirements match your trailer’s wiring and power source. Inspect the wiring route for a secure connection and clearance from moving or sharp parts, and follow the installation instructions. Product titles mention different wiring or connector options, but verify the exact connection details for the model you choose.
Final Words
For an A-frame setup, the POLESTAR 5000-pound jack is the lineup’s best overall fit when its listed capacity suits your trailer. Consider the Lippert if a 3,500-pound rating and integrated lights meet your documented needs, or a 7,500-pound option if you need a higher listed capacity. Before choosing, verify loaded tongue weight, mounting fit, lift range, and wiring; use remote or connector features only when they match your priorities.
