A strong electric tongue jack for an RV should match the trailer’s required tongue load, fit its A-frame mount, and include practical backup or weather features for setup away from home. This roundup compares 10 options, from 3,500-pound models to jacks listing capacities as high as 7,600 pounds. The POLESTAR Electric Trailer Jack 7500lb leads for its high stated capacity and included crank and waterproof cover.
Other picks offer wireless remote operation, a 7-way plug, or lower-capacity configurations. Product listings do not all describe capacity in the same way, and a jack’s stated rating is not a substitute for checking your trailer’s actual tongue weight.
Confirm mounting dimensions and power requirements before choosing, then consider which extras matter for your routine.
The POLESTAR Electric Trailer Jack 7500lb is the leading choice in this comparison because it lists a 7,500-pound load capacity and includes a crank and waterproof cover. Its stated capacity makes it a strong option for buyers seeking a higher-capacity A-frame jack, while the manual crank provides a listed backup method. Before buying, verify that your trailer’s actual tongue load and mounting setup are compatible; the listing’s capacity alone does not establish fit for every RV.

Detailed Reviews: Best Electric Tongue Jack For RV

#1 · Best Overall
1. POLESTAR Electric Trailer Jack 7500lb
- Load Capacity: 7500 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: RV, Trailer, Truck
Best for: Higher-capacity POLESTAR lifting.
Why it ranks #1: Lists 7,500-pound capacity for RVs and includes a crank and waterproof cover, combining a high stated rating with useful listed accessories.
A 7,500-pound dynamic load rating is the key reason to consider this POLESTAR electric jack for heavier RVs, trailers, boats, and off-road vehicles. Its stated static lifting power reaches 10,000 pounds, pairing a high load figure with the supplied crank and waterproof cover.
The 7,500-pound dynamic rating and 10,000-pound static lifting figure describe two different capacity measures, useful when checking a demanding trailer application against the jack’s stated limits. Alloy-steel construction and listed compatibility with RVs, trailers, and trucks give a broad vehicle context. The included crank offers a manual operating option, and the waterproof cover supports protection when the jack is stored or exposed between uses. At 23.9 pounds, handling it during installation takes some effort.
- 7,500-pound dynamic load capacity
- 10,000-pound static lifting capacity
- Compatible with RVs, trailers, and trucks
- Includes crank and waterproof cover
- At 23.9 pounds, it is a substantial item to handle during installation or removal.
Skip it if you need a jack under 20 pounds; the POLESTAR 5000-pound model weighs 21.7 pounds, though it also exceeds that threshold.
This model suits buyers whose trailer application calls for its 7,500-pound dynamic rating and who want a supplied crank and cover. Weigh the 23.9-pound jack against your installation and handling needs.

#2 · Best Remote Control
2. KYX Electric Trailer Jack 7500lb
- Load Capacity: lb 7500
- Material: Alloy Steel
- Compatible with Vehicle Type: RV
Best for: Remote-operated heavy lifting.
Why it ranks #2: Lists 7,500-pound capacity and wireless operation up to 30 meters, with a crank handle and cover included for RV use.
A wireless remote with a stated 30-meter maximum range lets you operate the KYX jack from beside the vehicle or the driver’s seat. Its 7,500-pound capacity makes that remote control relevant to buyers handling a heavier RV who want to adjust height without standing at the jack.
Remote operation is the defining workflow feature: the listing specifies control from the driver’s seat or beside the vehicle, with a maximum range of 30 meters. That can let the operator choose a position suited to uneven ground or poor weather. The 7,500-pound rating sets its stated load limit, while the included hand crank offers another operating method. A cover is also included, and the alloy-steel jack is listed for RV compatibility.
- 7,500-pound load capacity
- Wireless remote with a stated 30-meter maximum range
- Remote operation from the driver’s seat or beside the vehicle
- Includes hand crank and cover
- The listed compatible vehicle type is RV, not a broader list of trailer types.
Skip it if you need compatibility explicitly listed for trailers beyond RVs; the POLESTAR 7500-pound jack lists both RV and trailer use.
Choose the KYX if remote operation and a 7,500-pound rating match your RV setup. Its listed vehicle compatibility is RV, so buyers with another trailer type should weigh that stated scope before choosing.

#3 · Best 7-Way Plug
3. Kohree 6000 lbs Electric Trailer Jack
- Load Capacity: 6000 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: Trailer
Best for: Seven-way plug convenience.
Why it ranks #3: Its 6,000-pound rating suits buyers seeking an intermediate capacity, and the standard 7-way connector offers a distinct plug-in setup.
A standard 7-way trailer connector gives the Kohree a plug-in power connection for compatible setups, paired with one-button operation and a 6,000-pound rating. That combination targets RV and travel-trailer owners who want a heavier-capacity jack without a separate direct-wiring workflow.
The 7-way connector is presented as a quick, secure connection to the trailer, while one-button operation simplifies raising and lowering during hitching or leveling. Its 6,000-pound capacity places a clear boundary on the load it is intended to handle. The package also includes a cover, manual crank handle, and mounting bolts, supporting setup and a manual alternative. Kohree notes that after first use or long storage, the inner motor may need reactivation with a sizeable instantaneous current.
- 6,000-pound lifting capacity
- Standard 7-way trailer connector
- One-button operation
- Includes cover, manual crank handle, and mounting bolts
- The motor may need reactivation after first use or a long period without use.
Skip it if you need remote control or a rating above 6,000 pounds; the KYX 7500-pound jack includes wireless remote operation.
The Kohree suits owners with a compatible 7-way trailer connector seeking a 6,000-pound jack and supplied manual crank. Consider its stated motor-reactivation note if the jack will sit unused for an extended period.

4. POLESTAR Electric Trailer Jack 5000lb
- Load Capacity: 5000 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: RV, Trailer, Truck
Best for: Heavy trailer lifting.
Why it ranks #4: Lists 5,000-pound dynamic capacity and 7,500-pound static lifting power, plus a crank and waterproof cover for RV and trailer use.
A 5,000-pound dynamic load rating gives the POLESTAR a clear role for heavier RVs, trailers, boats, and off-road vehicles. Its electric A-frame format handles powered tongue lifting, while the included crank offers a manual option for operating the jack when needed.
The 5,000-pound dynamic rating and 7,500-pound static lifting figure distinguish this jack for buyers who need capacity beyond a 3,500-pound model. Alloy-steel construction suits trailer use, and its stated compatibility includes RVs, trailers, and trucks. The included crank provides a manual operating option, while the waterproof cover is supplied for storage or protection between trips. At 21.7 pounds, it is a substantial item to handle during installation or removal.
- 5,000-pound dynamic load capacity
- 7,500-pound static lifting capacity
- Compatible with RVs, trailers, and trucks
- Includes a crank and waterproof cover
- Its 5,000-pound dynamic rating is below the 7,500-pound rating of POLESTAR’s higher-capacity model.
Skip it if you need a dynamic rating above 5,000 pounds; POLESTAR’s 7,500-pound model covers that higher-capacity use case.
Choose this POLESTAR for an RV, trailer, boat, or off-road vehicle within its stated capacity, especially if a supplied crank and waterproof cover matter. Its dynamic rating is 5,000 pounds, so match that limit to your application.

#5 · Highest Capacity Tie
5. SEALIGHT Electric Trailer Jack 7500lb
- Load Capacity: 7500 lb
- Material: Carbon Steel
- Compatible with Vehicle Type: RV
Best for: Protected 7500-pound lifting.
Why it ranks #5: Lists a 7,500-pound capacity, LED lights, and a built-in circuit breaker; its RV compatibility is stated, though included items are less detailed.
A built-in circuit breaker that cuts power during improper operation pairs with a 7,500-pound rating in the SEALIGHT. Its 12V DC motor and LED lights add powered lifting and nighttime visibility for RV owners working around an A-frame trailer.
The 12V DC motor provides the powered lifting mechanism, with a stated 7,500-pound capacity to guide load selection. LED lights are intended to improve visibility during nighttime lifting, while the built-in circuit breaker automatically triggers power-off protection if the jack is improperly operated. Carbon-steel construction distinguishes its listed material, and the product is specified for RV compatibility. The supplied information lists housing as the included component, so buyers should account for that package detail.
- 7,500-pound load capacity
- 12V DC motor
- LED lights for nighttime lifting visibility
- Built-in circuit breaker power-off protection
- The listed compatible vehicle type is RV, rather than a broader set of trailer types.
Skip it if you need compatibility listed for trucks as well as RVs; the POLESTAR 7500-pound model specifies RV, trailer, and truck use.
Consider the SEALIGHT for an RV application needing its 7,500-pound rating, LED visibility, and circuit-breaker protection. Its listed compatibility names RVs, so check that scope against your intended vehicle type.

6. Kohree Electric Trailer Jack 4000lbs
- Load Capacity: 4000 lb
- Material: Heavy-duty steel with anti-rust coating
- Compatible with Vehicle Type: Camper, RV, Trailer
Best for: 4000-pound A-frame work.
Why it ranks #6: Lists 4,000-pound capacity and RV compatibility, with a cover, manual crank handle, and mounting bolts included.
A 4,000-pound dynamic rating and 6,000-pound static lifting figure give this Kohree two useful capacity measures for A-frame trailer owners. Its 12V DC motor raises or lowers the jack by button, while a manual crank is included for an alternate operating method.
The 12V DC motor provides powered lifting, and the listing says it raises eight inches in 47 seconds; that stated time helps set expectations for height adjustments. Its dynamic rating is 4,000 pounds, with static lifting power up to 6,000 pounds, so buyers should distinguish the two figures when selecting a load. Heavy-duty steel with an anti-rust coating, a cover, mounting bolts, and manual crank round out the supplied setup.
- 4,000-pound dynamic load capacity
- 6,000-pound static lifting capacity
- Listed eight-inch lift time of 47 seconds
- Includes cover, manual crank, and mounting bolts
- Its dynamic capacity is limited to 4,000 pounds.
Skip it if you need a dynamic rating above 4,000 pounds; the Kohree 6000-pound jack is listed with greater lifting capacity.
This Kohree fits A-frame trailer, camper, and RV owners who want powered lifting plus a manual crank. Use the 4,000-pound dynamic figure—not its higher static figure—to judge the working-load fit.

7. Lippert 3,500 lb Electric Trailer Tongue Jack
- Load Capacity: 3500 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: Trailer
Best for: Straightforward 3,500-pound lifting.
Why it ranks #7: A listed 3,500-pound trailer jack with a 5-3/8-inch foot pad, hand crank, and integrated LED lights described in the product details.
Helical-cut gears give the Lippert 3,500-pound electric tongue jack a stated quiet, efficient lifting mechanism. It replaces hand-cranking for powered raising and lowering, while the included hand crank remains available as a manual option for trailer owners who want both operating methods.
The 3,500-pound lift capacity sets the load boundary, and the helical-cut gears are described as quiet and efficient, making powered hitching and height adjustment the main workflow benefit. Four integrated LED lights help illuminate the jack area during operation. The package includes a 5-3/8-inch foot pad, clevis pin, and hairpin cotter pin, alongside the hand crank and jack body, so key listed pieces arrive together for setup.
- 3,500-pound lift capacity
- Quiet, efficient helical-cut gears
- Four integrated LED lights
- Includes foot pad, pins, and hand crank
- Its 3,500-pound capacity is lower than the 6,000-pound Kohree model’s stated rating.
Skip it if you need a rating above 3,500 pounds; the Kohree 6000-pound A-frame jack serves that higher-capacity requirement.
This Lippert fits buyers seeking powered trailer lifting with integrated work lights and a supplied manual crank. Keep its 3,500-pound capacity in view, and account for the listed trailer compatibility when selecting an application.

8. Pafessa 3500lb Electric Tongue Jack
- Load Capacity: 3500 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: RV, Trailer
Best for: A-frame range and footpad.
Why it ranks #8: Lists 3,500-pound capacity, 18 inches of travel, and a footpad adding 4.5 inches; the listing says it fits 2.25-inch mounting holes.
Eighteen inches of travel plus a footpad that adds 4.5 inches gives the Pafessa a useful range for adjusting trailer height. Its 3,500-pound capacity and fit for 2.25-inch A-frame mounting holes make it a candidate for compatible travel trailers and RVs.
The 18-inch jack travel works alongside the 6-inch adjustable footpad, which adds 4.5 inches of extension; that combination gives buyers more height adjustment than the travel figure alone. A 7-foot power cord supports a direct-grounding connection, though its wire terminals are not included. The stated 3,500-pound capacity and 2.25-inch mounting-hole fit help narrow compatibility, while the included weather-resistant cover and mounting hardware support installation and storage.
- 3,500-pound lift/tongue-weight capacity
- 18 inches of travel plus 4.5-inch footpad extension
- Fits 2.25-inch mounting holes on most A-frame trailers and RVs
- Includes mounting hardware and weather-resistant cover
- Wire terminals for the 7-foot power cord are not included.
Skip it if you need wire terminals supplied with the power cord; the Kohree 4000-pound jack includes wiring, according to its title.
Pick the Pafessa if your A-frame has 2.25-inch mounting holes and you value the additional footpad extension. Its rating is 3,500 pounds, and plan to source the power-cord terminals separately.

9. RVMATE Electric A-Frame Trailer Jack
- Load Capacity: 3500-4000 lb
- Material: Alloy Steel
- Compatible with Vehicle Type: Trailer
Best for: Nighttime A-frame operation.
Why it ranks #9: Lists 3,500–4,000-pound capacity and a one-year warranty, with LED lights and adjustable footplate height; vehicle compatibility lists trailer.
Four LED lights make the RVMATE easier to operate after dark, while its push-button lifting raises or lowers a trailer without hand-cranking. Its stated 3,500-to-4,000-pound capacity and adjustable footplate bracket offer a combination aimed at trailer owners managing hitching and leveling.
The electric button operation handles raising and lowering for connecting or disconnecting a trailer, and the stated 32-3/5-inch maximum extended height gives a clear height reference. The footplate bracket’s four holes allow height adjustment secured by a locking pin, helping tailor the foot position. Star washers are intended to cut through paint at the mounting plate for metal-to-metal grounding, while the LED lights support nighttime operation.
- 3,500-to-4,000-pound stated capacity
- Push-button raising and lowering
- Four-hole footplate bracket for height adjustment
- LED lights support nighttime operation
- The supplied capacity is stated as a 3,500-to-4,000-pound range rather than a single figure.
Skip it if you need a single clearly stated capacity rating; the Lippert 285318 specifies 3,500 pounds.
Consider the RVMATE for trailer owners who want button-operated hitching and lighting for nighttime use. Its capacity is listed as a range, and the adjustable footplate uses a locking pin to secure the selected height.

10. Dnigh 7600LBS Electric Trailer Jack
- Load Capacity: 7600 lb
- Material: Iron-Zinc Alloy
- Compatible with Vehicle Type: RV, Trailer
Best for: Remote-controlled high capacity.
Why it ranks #10: Lists a 7,600-pound capacity and RV compatibility, but the supplied details give fewer fit, operation, and included-component specifics than the higher-ranked options.
Two remote controls come with the Dnigh, whose 7,600-pound rating places it among the higher-capacity options in this roundup. That pairing lets RV and trailer owners use remote operation without relying on a single supplied controller, according to the product title and included-components listing.
The 7,600-pound stated capacity gives buyers a concrete load limit to compare with their RV or trailer requirements. Two remote controls are specified in the title, making remote operation the central convenience, while the IP65 waterproof claim is also stated in the title for buyers considering exposure. The iron-zinc alloy construction and 30-inch listed dimensions help describe the unit, but the supplied information does not identify a crank or other included operating accessories.
- 7,600-pound load capacity
- Two remote controls specified in the title
- IP65 waterproof claim specified in the title
- Compatible with RVs and trailers
- The included-components listing names only the electric trailer jack.
Skip it if you want a manual crank included; the KYX 7500-pound remote jack lists a hand crank with its cover.
The Dnigh suits RV or trailer owners who value two remote controls and a 7,600-pound rating. Its included-components list names only the jack, so account for that when planning installation and manual operation.

View on AmazonCheck what each capacity figure actually means
A listed load capacity does not always describe the same kind of load, so compare the wording before treating ratings as interchangeable. POLESTAR’s 5,000-pound model specifies 5,000 pounds of dynamic load and 7,500 pounds of static lifting power; its 7,500-pound model likewise distinguishes dynamic load from static lifting power. Kohree’s 4,000-pound listing also states a 6,000-pound static figure.
Other products simply list a load capacity, including the 3,500-pound Lippert and 7,600-pound Dnigh. These figures are not a measurement of your RV’s tongue weight, and a jack’s rating does not by itself confirm that it can safely support your particular trailer.
Check the trailer maker’s guidance and actual tongue load, and do not assume a static figure is the appropriate rating for routine lifting. When details are unclear, confirm the rating’s meaning with the manufacturer before purchase.
Plan for power loss and setup differences
A power interruption can leave an electric jack unusable unless you have a practical backup, and the included equipment varies across these listings. POLESTAR’s 5,000- and 7,500-pound models include a crank, as do the KYX, Kohree 4,000-pound, and Lippert models. Pafessa includes an emergency crank socket, but its listing says the driver handle is not included.
The Kohree 6000-pound model lists a manual crank handle and 7-way connector, while the Dnigh listing names only the electric jack among included components. Wiring and mounting also deserve attention: Pafessa specifies 2.25-inch mounting holes and a 7-foot power cord, while other listings do not provide the same dimensions in the supplied data.
Confirm the mount, wiring connection, and backup method for your trailer before relying on a jack during travel.
How to Choose an Electric RV Tongue Jack
Capacity and load rating
Look for a rating that matches your trailer’s actual tongue load and the manufacturer’s guidance, rather than selecting by the largest number alone. This lineup spans listed capacities from 3,500 pounds on the Lippert and Pafessa models to 7,600 pounds on the Dnigh; several models list 7,500 pounds. Some listings distinguish dynamic and static figures: the POLESTAR 5000lb and Kohree 4000lbs provide both, so read each label carefully.
A buyer with a higher required rating may prefer the POLESTAR 7500lb or KYX 7500lb, while someone whose trailer needs a lower rating could consider the Lippert or Pafessa. Verify the relevant rating before purchase because listing figures are not a substitute for measuring your trailer’s load.
Mount, travel, and height adjustment
Check the A-frame mounting pattern and the total lift range against your trailer before choosing a jack. Pafessa states that it fits 2.25-inch mounting holes and provides 18 inches of travel, with a footpad adding 4.5 inches. RVMATE lists a maximum extended height of 32-3/5 inches and a fully retracted height of 9 inches, while its footplate bracket has four height-adjustment holes.
Those details help buyers whose setup needs a particular travel range or adjustable foot position. If your trailer has a less common mounting plate or clearance constraint, prioritize confirming fit rather than assuming every A-frame jack is interchangeable.
The supplied specifications do not give comparable mounting dimensions for every product, so check the manufacturer’s fit information where needed.
Power connection and useful extras
Choose a power arrangement and backup features that suit how you hitch and travel. Kohree’s 6000-pound jack lists a standard 7-way trailer connector and one-button operation; Pafessa instead lists a 7-foot cord for direct grounding and notes that wire terminals are not included. For operation away from the jack, KYX supplies wireless remote control with a stated range of up to 30 meters.
Several models include a manual crank, while Pafessa includes a crank socket without the driver handle. Covers are listed with both POLESTAR models, KYX, and both Kohree models.
Buyers who value remote operation may favor KYX; those wanting a listed 7-way connection may prefer Kohree 6000lbs. Confirm connector, wiring, and backup requirements against your RV.
Which Electric Tongue Jack Should You Choose?
For a high-capacity choice with a crank and waterproof cover, choose POLESTAR Electric Trailer Jack 7500lb, the overall leader. If operating the jack remotely matters most, KYX Electric Trailer Jack 7500lb lists a 30-meter remote range and includes a crank and cover. Buyers who want a listed 7-way connection can consider Kohree 6000 lbs Electric Trailer Jack.
For a lower stated capacity with a manual backup and cover, Kohree Electric Trailer Jack 4000lbs is a practical match to compare against your trailer’s load. If mounting dimensions and added footpad height are priorities, inspect Pafessa 3500lb Electric Tongue Jack’s 2.25-inch hole fit and 18-inch travel.
In every case, verify tongue load, mounting fit, and wiring before ordering.

Frequently Asked Questions
How do I measure my RV’s tongue weight before choosing an electric jack?
Measure the trailer’s tongue load in its travel-ready condition, with typical cargo and fluids aboard. Use a tongue-weight scale or have a suitable scale measure the load at the coupler, following its instructions. Compare that reading with the jack’s stated capacity, and verify the mounting setup separately; capacity alone does not confirm fit.
How can I confirm an electric tongue jack will fit my trailer’s A-frame mounting plate?
Compare the jack’s mounting-hole pattern and mounting dimensions with your trailer’s A-frame plate before ordering. Check the plate’s hole spacing, shape, and available clearance against the product listing or manufacturer information. Also confirm the jack’s travel and footpad arrangement suit your setup; do not assume that an A-frame label guarantees a match.
What should I do if the jack loses power while hitching or leveling?
Stop operating it and keep people clear of the trailer’s movement. Check the power connection and wiring only when safe, following the product instructions. If that model includes a manual crank, use it as directed; otherwise, do not force the jack.
Secure the trailer with suitable supports and resolve the power issue before continuing.
How can I check whether my trailer’s wiring matches the jack?
Read the jack’s wiring and connection requirements, then compare them with your trailer’s available power connection before installation. Check the product instructions for any specified wiring or connection details, and confirm polarity and secure connections as directed. If the requirements are unclear or do not match, ask a qualified installer rather than improvising.
What details should I verify before ordering an electric tongue jack?
Verify three things before ordering: your loaded trailer’s tongue load, the jack’s mounting-hole fit and available clearance, and the wiring or power connection. Then check the listed travel and any included backup crank or cover if those matter to your use. A listed capacity by itself does not establish compatibility with your RV.
Final Words
For a higher-capacity A-frame option with a listed manual backup and waterproof cover, the POLESTAR 7500lb is the leading choice in this comparison. Choose the KYX instead if its listed remote range is a priority, or compare the Kohree options for a 7-way connection or lower stated capacity. Before ordering any model, verify your loaded tongue weight, mounting fit, and wiring; listed capacity alone cannot establish compatibility.
