A strong power tongue jack for a travel trailer should suit the trailer’s tongue load, fit its A-frame mounting arrangement, and include practical backup or weather-protection parts. The Kohree 7500lbs Electric Trailer Jack leads this roundup with a listed 7,500-pound capacity, dual-wire connection, and built-in level. Options here span 3,500 to 7,500 pounds, with differences in listed materials, dimensions, lifting details, and included hardware.
Some listings also specify a manual crank or waterproof cover, useful details to compare before buying. Capacity figures are not interchangeable with a trailer’s total weight, so check the jack maker’s instructions and your trailer requirements.
The comparisons below focus on facts supplied for each product; confirm fit, wiring, and operating limits before installation.
The Kohree 7500lbs Electric Trailer Jack is the leading pick for a travel-trailer owner who wants a high listed capacity and practical setup features. It is rated at 7,500 pounds and lists a dual-wire direct connection, built-in level, cover, manual crank handle, and three mounting bolts. Those facts make it the strongest all-around match in this group, though the capacity alone does not confirm compatibility with every A-frame or trailer.
Verify mounting dimensions and the load the jack must lift before choosing.

Detailed Reviews: Best Power Tongue Jack For Travel Trailer

#1 · Best Overall
1. Kohree 7500lbs Jack
- Load Capacity: 7500 lb
- Material Type: Alloy Steel
Best for: Level-aware heavy trailers.
Why it ranks #1: Its listed 7,500-pound capacity, dual-wire connection, built-in level, cover, crank handle, and mounting bolts make it a well-equipped travel-trailer choice.
A built-in level is the Kohree jack’s clearest differentiator, giving travel-trailer owners a leveling reference alongside its 7,500-pound lifting capacity. Button operation and a dual-wire direct connection are also specified, combining powered raising and lowering with a stated wiring approach for installation.
The 7,500-pound capacity makes this a high-capacity option among the listed jacks, while the built-in level gives owners a reference when positioning a trailer. Press-button controls support powered raising and lowering, and the dual-wire direct connection is described as enabling fast installation. Alloy-steel construction and an included jack cover address the hardware and covering needs; the package also lists a manual crank and three mounting bolts for installation or manual operation.
- 7,500-pound lifting capacity
- Built-in level
- Press-button operation
- Includes jack cover, manual crank, and three mounting bolts
- The listing gives no height range, so it offers less stated reach guidance than the VEVOR EJ3550B.
Skip it if you need a stated operating-height range before choosing; the VEVOR EJ3550B lists 9.84 to 33.85 inches.
This Kohree fits buyers prioritizing a built-in leveling reference and a 7,500-pound rating for a travel trailer or camper. Its dual-wire connection and included mounting bolts matter during installation; check that the jack’s available height suits your setup.

#2 · Best 5000-Pound Option
2. POLESTAR 5000lb Jack
- Dimensions: 7.28 x 9.84 x 32.28 in
- Weight: 21.7 lb
- Load Capacity: 5000 lb
- Material Type: Alloy Steel
Best for: Higher-capacity trailer setups.
Why it ranks #2: The 5,000-pound dynamic and 7,500-pound static figures offer clear load distinctions, and the package includes a crank and waterproof cover.
A 5,000-pound dynamic rating gives the POLESTAR 10201091 more stated lifting capacity than a 3,500-pound tongue jack, while its 7,500-pound static rating adds a separate measure for stationary support. It suits buyers who want an electric A-frame jack for heavier trailer, RV, boat, or off-road-vehicle applications.
The alloy-steel construction pairs with the stated 5,000-pound dynamic capacity, giving buyers a clear load figure to compare with their trailer requirements. A 7,500-pound static rating distinguishes its stationary support specification from its lifting rating. The included crank offers a manual operating option, and the waterproof cover gives owners a supplied cover for storage or outdoor use. At 21.7 pounds, it is a substantial component to account for during installation and handling.
- 5,000-pound dynamic load capacity
- 7,500-pound static lifting capacity
- Alloy-steel construction
- Includes crank and waterproof cover
- Its 5,000-pound dynamic rating is lower than the 7,500-pound ratings of some listed jacks.
Skip it if you need a stated 7,500-pound dynamic rating; the Kohree 7500lbs Electric Trailer Jack lists that capacity.
Choose this POLESTAR for an RV, trailer, boat, or off-road-vehicle setup whose requirements fit its 5,000-pound dynamic rating. Its higher static rating and included crank are useful considerations, but verify your load against the dynamic figure.

#3 · Best Integrated Lighting
3. Lippert 3500lb Jack
- Dimensions: 32.75 x 12.5 x 7.25 in
- Weight: 28.6 lb
- Load Capacity: 3500 lb
- Material Type: Alloy Steel
Best for: Quiet electric hitching.
Why it ranks #3: Its 3,500-pound capacity suits lighter loads, while the description lists integrated LED lights and helical-cut gears; the package includes mounting pins and a foot pad.
Helical-cut gears give Lippert’s 3,500-pound electric tongue jack a specifically stated quiet, efficient operating mechanism, enabling powered raising and lowering without relying on a hand crank for routine hitching. Four integrated LED lights add illumination to the jack area, a practical feature for low-light setup.
The 3,500-pound lift capacity sets the load boundary for choosing this jack, while the helical-cut gears are described as quiet and efficient for powered operation. Four integrated LED lights can illuminate the work area around the tongue during setup. Lippert also describes installation as easy, and the package lists a clevis pin, foot pad, hairpin cotter pin, hand crank, and jack body, supplying key mounting and manual-use components.
- 3,500-pound lift capacity
- Quiet, efficient helical-cut gears
- Four integrated LED lights
- Includes clevis pin, foot pad, cotter pin, and hand crank
- The 3,500-pound capacity is below the 4,000-pound VEVOR EJ3550B rating.
Skip it if you need a load rating above 3,500 pounds; the VEVOR EJ3550B lists a 4,000-pound capacity.
This Lippert suits trailer owners seeking powered hitching, quieter stated gear operation, and integrated lighting. Keep its 3,500-pound capacity in view when matching it to a trailer, and account for the listed mounting hardware during installation.

#4 · Best 4000-Pound Option
4. Kohree 4000lb Jack
- Dimensions: 7.09 x 5.71 x 24.41 in
- Weight: 20.5 lb
- Load Capacity: 4000 lb
- Material Type: Heavy-duty steel with anti-rust coating
Best for: Fast button-operated lifting.
Why it ranks #4: The 4,000-pound dynamic and 6,000-pound static ratings are specified, and the kit lists a cover, manual crank, and three mounting bolts.
Kohree lists a 47-second time to lift 8 inches, compared with 84 seconds for other products, giving this 4,000-pound jack a concrete speed claim to assess. Its 12-volt motor, push-button controls, and separate 6,000-pound static rating round out the stated operating and capacity details.
The listed 47-second time for an 8-inch lift provides a specific operating benchmark, while push-button control lets owners raise or lower an A-frame trailer automatically. Its 4,000-pound dynamic capacity and 6,000-pound static lifting figure distinguish load use from stationary support. Heavy-duty steel with an anti-rust coating addresses the stated construction, and the package includes wiring, a cover, a manual crank handle, and three mounting bolts for installation and manual override.
- 4,000-pound dynamic capacity
- 6,000-pound static lifting power
- Listed 47-second time for an 8-inch lift
- Includes wiring, cover, crank handle, and three mounting bolts
- Its 4,000-pound dynamic rating is below the 7,500-pound Kohree KR1217-KO-US-FBA rating.
Skip it if you need a 7,500-pound rating; the Kohree KR1217-KO-US-FBA lists that capacity and a built-in level.
This Kohree suits A-frame trailer owners who value button operation, a stated 8-inch lift time, and included wiring and mounting hardware. Match the 4,000-pound dynamic rating to your load, and consider its separate static figure for stationary support.

5. VEVOR 5000lb Jack
- Dimensions: 9.65 x 5.51 x 28.94 in
- Weight: 22.9 lb
- Load Capacity: 5000lbs lb
- Material Type: Carbon Steel
Best for: Rust-resistant 5,000-pound lifting.
Why it ranks #5: A 5,000-pound rating and galvanized rust-resistant coating suit owners seeking a higher-capacity steel jack; it includes a manual crank and weatherproof cover.
A galvanized rust-resistant coating over carbon steel distinguishes this 5,000-pound VEVOR jack for owners considering outdoor exposure. The package also includes a manual crank handle and weatherproof cover, pairing powered tongue-jack operation with supplied options for manual use and covering when the jack is not in use.
The 5,000-pound capacity gives buyers a clear load limit to compare with their RV or trailer, while the galvanized coating is specified as rust resistant for use in various environments. A two-way connector is named in the title, providing a defined connection feature to consider in the installation workflow. The included manual crank handle offers a manual operating option, and the weatherproof cover supplies a way to cover the jack between uses.
- 5,000-pound lifting capacity
- Carbon steel with galvanized rust-resistant coating
- Two-way connector
- Includes manual crank handle and weatherproof cover
- Its listed lifting range is inconsistent: the title says 10–28.3 inches, while the features say 10–33.8 inches.
Skip it if you need an unambiguous listed lift range; the VEVOR EJ3550B specifies 9.84 to 33.85 inches.
Choose this VEVOR if a 5,000-pound rating, galvanized coating, and supplied cover suit your RV or trailer use. Its stated height range differs between title and features, so that discrepancy is a meaningful boundary when planning installation.

6. VEVOR 4000lb Jack
- Dimensions: 33.85 in
- Weight: 9.8 kg
- Load Capacity: 4000 lb
- Material Type: Carbon Steel
Best for: Outdoor trailer lifting.
Why it ranks #6: The 4,000-pound rating, carbon-steel construction, waterproof cover, crank handle, and stated two-year manufacturer warranty make it a practical mid-capacity option.
A 4,000-pound capacity paired with a stated 9.84-to-33.85-inch range gives this VEVOR jack both a load figure and working-height span to compare against a trailer. Its carbon-steel body has a protective coating, and a waterproof sunshade cover is included for outdoor ownership.
The 4,000-pound rating helps define the trailer loads this jack is intended to lift, while the listed 9.84-to-33.85-inch range gives buyers a span to compare with their coupling and parking needs. Carbon steel with a protective coating is specified to withstand splashes and tough outdoor conditions. The included crank handle provides a manual operating option, and the waterproof cover is supplied for covering the jack when not in use.
- 4,000-pound lifting capacity
- 9.84-to-33.85-inch listed range
- Carbon steel with protective coating
- Includes crank handle and waterproof cover
- Its 4,000-pound capacity is lower than the 5,000-pound VEVOR EJ5021B rating.
Skip it if you need a 5,000-pound VEVOR jack; the EJ5021B lists that capacity and a galvanized rust-resistant coating.
Consider this VEVOR for an RV, horse, utility, or yacht trailer whose load and required jack height fit its stated range. The coated carbon steel and supplied cover suit outdoor use, while the 4,000-pound rating remains the key boundary.

#7 · Highest Listed Capacity
7. KYX 7500lb Jack
- Load Capacity: 7500 LB
- Material Type: Carbon Steel
Best for: High-capacity A-frame lifting.
Why it ranks #7: Its stated 7,500-pound capacity is among the group’s highest, with a 12V DC motor and carbon steel with anti-rust coating; included components are unspecified.
A 7,500-pound rating and 12-volt DC motor make the KYX an option for A-frame trailer owners seeking powered raising and lowering at a high stated capacity. Its carbon-steel construction has an anti-rust surface coating, with a waterproof cover also named in the product title.
The 12-volt DC motor is specified to raise or lower an A-frame trailer, while the 7,500-pound rating establishes the capacity to compare against the intended load. Carbon steel with an anti-rust coating is described as resisting harsh outdoor conditions and water splashes. A waterproof cover is identified in the title as an included accessory. The supplied details do not state a lift range, so buyers must weigh capacity and construction without a listed height span.
- 7,500-pound load capacity
- 12-volt DC motor
- Carbon-steel construction
- Anti-rust coating and waterproof cover
- The supplied details do not state a lift range, limiting height comparison before purchase.
Skip it if you need a stated lift range to plan height; the RVMATE RMETJ lists a 9-inch retracted height and 323⁄5-inch maximum.
Consider this KYX for an A-frame trailer whose load fits the 7,500-pound rating and whose owner values coated carbon steel. The supplied details identify motor and cover features but no height range, an important installation consideration.

8. POLESTAR 3500lb Jack
- Dimensions: 3.94 x 3.94 x 19.69 in
- Weight: 22 lb
- Load Capacity: 3500 lb
- Material Type: Alloy Steel
Best for: Mid-capacity A-frame trailers.
Why it ranks #8: This 3,500-pound model lists a 5,000-pound static lifting figure and includes a crank and waterproof cover, but offers less rated capacity than higher-ranked choices.
A 3,500-pound dynamic rating with 5,000 pounds of stated static lifting power gives the POLESTAR 10201089 two distinct capacity figures for trailer owners to evaluate. Its 12-volt motor-driven operation is described as easing travel-trailer and boat-trailer coupling and uncoupling from the hitch.
The 3,500-pound dynamic capacity is the key figure for matching this jack to a trailer, while the separate 5,000-pound static rating describes its stated stationary lifting power. A 12-volt motor drives electric operation for coupling and uncoupling, reducing reliance on the included crank during routine hitching. The alloy-steel body comes with a waterproof cover, and the listing also advises checking for damaged or worn parts before use.
- 3,500-pound dynamic load capacity
- 5,000-pound static lifting power
- 12-volt motor-driven operation
- Includes crank and waterproof cover
- Its 3,500-pound dynamic capacity is lower than the 4,000-pound Kohree HY1711 rating.
Skip it if you need a 4,000-pound dynamic rating; the Kohree HY1711-KO-US-FBA-2 lists that capacity.
This POLESTAR suits travel-trailer or boat-trailer owners seeking motorized hitching within its 3,500-pound dynamic rating. The separate static figure, included crank, and waterproof cover add useful context, but match your load to the dynamic capacity.

9. RVMATE A-Frame Jack
- Weight: 10.52 kg
- Load Capacity: 3500-4000 lb
- Material Type: Alloy Steel
Best for: Low-light height adjustment.
Why it ranks #9: Its stated 3,500–4,000-pound capacity, 32-3/5-inch maximum extended height, adjustable footplate holes, and LED light provide useful setup details.
An integrated LED light and four footplate-bracket adjustment holes give the RVMATE jack useful setup details beyond its 3,500-to-4,000-pound capacity. The light is identified for nighttime operation, while the locking-pin positions let owners adjust footplate height to suit their trailer setup.
The stated 9-inch fully retracted height and 323⁄5-inch maximum extended height give buyers a concrete span to compare with their trailer. Four holes in the footplate bracket allow height adjustment using a locking pin, while star washers are intended to penetrate the mounting-plate paint for metal-to-metal grounding. Button controls power lifting and lowering, and the LED light supports nighttime operation. Its listed capacity spans 3,500 to 4,000 pounds.
- 3,500-to-4,000-pound listed capacity
- 9-inch retracted and 323⁄5-inch maximum extended heights
- Four footplate adjustment holes with locking pin
- LED light for nighttime operation
- The stated capacity is a 3,500-to-4,000-pound range rather than one single figure.
Skip it if you need one stated 5,000-pound rating; the POLESTAR 10201091 lists a 5,000-pound dynamic capacity.
This RVMATE suits trailer owners who value nighttime illumination and adjustable footplate height, with a listed capacity range of 3,500 to 4,000 pounds. Compare its stated extension and mounting details with the height and grounding needs of your setup.

10. Pafessa 3500lb Jack
- Dimensions: 30.7 x 8.68 x 7.67 in
- Weight: 8 kg
- Load Capacity: 3500 lb
- Material Type: Alloy Steel
Best for: Extended reach with drop foot.
Why it ranks #10: The 3,500-pound rating, 18 inches of travel, extra footpad extension, weather-resistant cover, and mounting hardware are useful, but the listing is less complete on warranty and dimensions.
Eighteen inches of travel plus a 4.5-inch drop-foot extension give the Pafessa jack a stated 22.5 inches of combined reach to consider for A-frame trailers. Its 3,500-pound capacity, 6-inch adjustable footpad, and 7-foot direct-grounding power cord further define the installation and lifting setup.
The 18-inch travel and additional 4.5-inch footpad extension provide a combined stated reach of 22.5 inches, helping buyers assess whether the jack can reach their needed position. The 6-inch adjustable footpad offers a specified contact dimension, while the 7-foot cord is intended for direct grounding; wire terminals are not included. The 3,500-pound capacity and 2.25-inch mounting-hole fit provide further checks for load and A-frame installation compatibility.
- 3,500-pound capacity
- 18 inches of travel plus 4.5-inch footpad extension
- 6-inch adjustable footpad
- 7-foot direct-grounding power cord
- The emergency crank socket is included, but its driver handle is not.
Skip it if you want a supplied manual crank handle; the POLESTAR 10201089 lists a crank among its included components.
Choose the Pafessa if its 3,500-pound capacity and extended footpad reach suit your A-frame trailer. The 7-foot direct-grounding cord and stated mounting-hole size help plan installation, but the emergency crank socket requires a separate driver handle.

View on AmazonAvoid confusing trailer weight with jack load
A trailer’s advertised total weight is not the same figure as the load its tongue jack must lift. The supplied listings show why you should compare the rating carefully: POLESTAR lists a 5,000-pound dynamic load and 7,500-pound static lifting power for its 5000lb model, while Kohree lists 4,000 pounds dynamic and 6,000 pounds static for its 4000lb model. Those terms describe different stated conditions, so do not treat the larger static number as the ordinary operating capacity.
A jack that is undersized for the actual lifting task may struggle or be overloaded; a larger number alone also does not establish that the jack fits your trailer. Check the trailer maker’s requirements, the jack’s operating instructions, and the mounting arrangement.
If the product listing does not explain how its figure applies to your use, ask the manufacturer rather than making the total trailer weight your only sizing input.
Check fit and keep a manual backup plan
A matching capacity does not guarantee that a jack will fit or can be operated in every situation. These products vary in their stated dimensions and installation details: the RVMATE listing gives a 9-inch fully retracted height and 32-3/5-inch maximum extended height, while the Pafessa listing specifies fit for 2.25-inch mounting holes and 18 inches of travel plus footpad extension. Confirm your trailer’s A-frame, bolt pattern, available clearance, and required height against the complete product instructions before purchase.
Power and grounding also matter: RVMATE notes that its star washers help penetrate paint for metal-to-metal grounding, and Pafessa describes a direct-grounding cord with wire terminals not included. Several options supply a crank, but parts differ; check that the backup method and any required hardware are actually included.
A manual crank can be useful if power is unavailable, but it does not remove the need for correct installation and safe operation.
How to Choose a Travel-Trailer Tongue Jack
Capacity and load ratings
Look for a rating that matches the jack’s actual lifting task, not simply the trailer’s total weight. This group lists capacities from 3,500 pounds on the Lippert and POLESTAR models to 7,500 pounds on the Kohree and KYX models. Some listings distinguish dynamic and static figures: POLESTAR’s 5000lb model states 5,000 pounds dynamic and 7,500 pounds static, while Kohree’s 4000lb model states 4,000 and 6,000 pounds respectively.
Owners with a higher required lifting load should investigate the higher-rated options, while lighter-load situations may suit a 3,500-pound model. Confirm the applicable rating and trailer requirements in the manufacturer’s instructions before deciding.
Lift range and available clearance
Choose a lift range that accommodates your coupler height and the ground conditions where you park. The listings provide different levels of detail: RVMATE states a 9-inch retracted height and a 32-3/5-inch maximum extended height, while Pafessa lists 18 inches of travel plus 4.5 inches from its footpad. VEVOR’s 5000lb listing gives conflicting lift-range figures in its title and feature text, so confirm the exact usable range with the manufacturer.
A trailer owner who needs extra adjustment should prioritize verified travel and footpad information; someone with a tight installation space should check retracted height and dimensions first. Do not assume that a headline range includes the foot or mounting arrangement in the way your installation requires.
Materials and included backup parts
Compare construction and the components supplied, since these vary across the choices. The products list alloy steel, carbon steel, and heavy-duty steel with anti-rust coating; VEVOR’s 5000lb model specifically describes a galvanized rust-resistant coating. Several kits include a manual crank and cover, including both POLESTAR models and the Kohree 4000lb jack.
The Lippert package lists a hand crank, foot pad, clevis pin, and cotter pin, while Pafessa includes a crank socket but says the driver handle is not included. A buyer who wants an available manual backup should check the exact crank parts in the package.
Those prioritizing exposure protection should verify the cover type and fit rather than assuming every listed cover offers the same protection.
Which Power Tongue Jack Fits My Travel Trailer?
For a high listed capacity plus setup features, choose the Kohree 7500lbs Jack: it lists 7,500 pounds, dual-wire connection, built-in level, cover, and manual crank. If you want a clearly differentiated 5,000-pound dynamic rating with a higher static figure, the POLESTAR 5000lb Jack is a strong alternative. For a 4,000-pound option with a specified 6,000-pound static rating and crank, consider the Kohree 4000lb Jack.
Lighter-load buyers can compare the Lippert 3500lb Jack, which lists integrated LED lights, with the POLESTAR 3500lb Jack and its waterproof cover. If exact installation height or extra footpad reach matters, investigate the RVMATE A-Frame Jack or Pafessa 3500lb Jack and verify fit against your trailer.
Confirm the actual load, mounting, and wiring before ordering.
Frequently Asked Questions
How do I calculate the tongue load my travel trailer jack must handle?
Use the trailer’s actual tongue load when it is loaded for travel, rather than its total weight alone. Check the trailer documentation or ask its manufacturer how to measure the load safely. Choose a jack whose applicable rating meets that load, and do not treat a listed capacity as proof of fit.
How can I confirm an electric tongue jack fits my trailer’s A-frame and mounting holes?
Compare the jack’s mounting pattern and dimensions with the trailer’s A-frame plate and existing holes before ordering. Also check clearance, required lift, and wiring access against your trailer. If the product listing does not provide a needed measurement, ask the seller or trailer manufacturer rather than assuming a standard fit.
What should I do if a power tongue jack loses electrical power while hitching?
Stop operating it and secure the trailer against movement before troubleshooting. Check the power connection and wiring according to the jack’s instructions; disconnect power before handling wiring. If that model includes a manual crank, use it only as directed.
If it does not, or the cause is unclear, get qualified help.
What is the difference between a jack’s dynamic and static ratings?
A dynamic rating refers to lifting capacity, while a static rating refers to capacity when the load is held in place. Check which rating a listing provides and compare it with the load the jack must lift and support. Do not substitute a higher static figure for an insufficient lifting rating.
Do a cover and wiring details matter when choosing a power tongue jack?
Yes: check both against your use and installation needs. A listed cover can help protect the jack, but it does not establish a particular weather rating. Confirm the wiring arrangement is compatible with your trailer and follow the product instructions.
The listed models vary in features, so compare details rather than assuming they are interchangeable.
Final Words
For the strongest all-around match in this group, choose the Kohree 7500lbs Jack if its listed 7,500-pound capacity and setup features suit your needs. Consider the POLESTAR 5000lb for its stated dynamic and static ratings, or compare the lower-capacity options for lighter loads. Before ordering, verify the load the jack must lift, mounting dimensions, clearance, and wiring against your trailer; capacity alone does not establish compatibility.
