A power jack replaces the hand crank on your trailer tongue. Three things decide the fit. Dynamic lift capacity must cover your tongue weight. Retracted height must clear your hitch. Lift speed and a manual override matter for convenience and backup. We put 10 products on one spec sheet, with capacity, heights, weight, motor and protection features side by side. Many makers leave some numbers out, so we note what is missing and what the listings add.

We reviewed 20 electric tongue jacks and kept only the 10 that pass every check below. Those are ranked by a Best Score built from spec fit for this job, sales rank.
These reviews are based on specifications and listing information only. They cover the five top-ranked jacks and focus on capacity, height and backup features.
Highest lift ratings and a low retracted height
Among the models that list static capacity, this jack leads at 10000 lb. Its dynamic rating is 7500 lb, tied for the highest on the page. For a travel trailer, dynamic capacity is the number that counts when you lift the tongue off the ball. It leaves room for heavier tongue weights. It leads our ranking.
Height is where this jack fits tight hitches. It retracts to 9 in, tied for the lowest among the models that list it. The listing gives a lift range of 9 in to 27 in, and a 4.5 in drop leg takes it to 31.5 in. The maker does not publish a lift speed, so raise and lower time is unknown.
Extras include a built-in circuit breaker, an LED light, and a waterproof cover. The listing says it ships with a 7-way plug, so no hardwiring is needed if your vehicle socket is compatible. At 23.9 lb, it is not light. The specs do not list a manual crank.
VerdictA strong pick for heavy tongue weights and low hitches, with no listed manual backup.
Tallest reach and a handheld remote
This VEVOR HH7500 shares the top dynamic rating of 7500 lb. It also has the highest max extended height among models that list it, at 33.85 in. The listing says a 5-position drop leg adds 6 in. That helps when you park on uneven ground or hitch a trailer with a high coupler.
The tradeoff is height when retracted. At 9.84 in, it is the tallest closed jack among the models that list it, so check your hitch clearance first. It is also the heaviest listed, at 28.66 lb. Mounting is flexible, since the listing describes base holes that rotate 90° so the pickup tailgate can open.
Controls are a rocker switch plus a handheld remote, so you can raise or lower from a distance. A top crank allows manual lifting if power is lost. The package includes an LED work light and a weather cover. The specs do not list a circuit breaker, and no lift speed is published.
VerdictA capable 7500 lb jack for reach and remote control, but it is tall and heavy.
A lighter Polestar for mid-weight tongues
This is the 5000 lb version of the Polestar jack. It lists a dynamic rating of 5000 lb and a static rating of 7500 lb. Both are below the 7500 lb model's ratings. Dynamic is the load it can lift under power. Check your trailer's tongue weight against that number, not the static figure. It ranks third on our list.
At 9 in closed, it clears low hitches as well as the top-ranked Polestar. Max extended height is 31.5 in with the adjustable drop leg. It weighs 21.72 lb, lighter than the two 7500 lb jacks. The maker does not publish a lift speed or a voltage range.
Power comes from a direct hookup to the trailer's 12V battery, according to the listing. The listing calls this a stable supply. You wire the positive and negative leads yourself. A circuit breaker, LED light and rain cover are included. No manual crank is listed, so a dead battery could leave the jack stuck.
VerdictA sensible mid-range Polestar for lighter trailers that need a low retracted height and a built-in breaker.
Light, compact jack for smaller trailers
The KYX DJS013RUS is built for lighter loads. Its dynamic rating is 3500 lb, the lowest among the models that list it. Match that to your tongue weight first, since this rating leaves the least margin. The listing mentions RV, horse and multipurpose trailers. Our ranking puts it fourth.
Size is its strength. It retracts to 9 in and reaches 32 in, with no separate drop leg listed. At 18 lb, it is the second lightest among the models that list weight. That makes it easier to mount and carry. The motor is 12V DC, according to the listing.
It includes a built-in overload breaker that cuts power when current runs high and restarts after the motor cools. A hand crank is included for power loss, along with a waterproof cover and an LED light. The listing describes a carbon steel body with an anti-rust coating. The maker does not publish a lift speed or a static rating.
VerdictA light, simple jack for small trailers, but not for heavy tongue weights on a travel trailer.
Kohree KR1212 pairs 5000 lb with a hand crank
The Kohree KR1212 lists a dynamic rating of 5000 lb and a static rating of 7500 lb. That is the same pair of numbers as the 5000 lb Polestar. Our ranking puts it fifth. The spec sheet gives no motor power, lift speed or voltage range. Use the dynamic figure when matching to your tongue weight.
Height numbers are 9.8 in retracted and 31.7 in extended. The listing says a 5-gear drop leg adds 8 in, and the main lift is 22 in. The jack weighs 21.16 lb. Two LED lights help at night. Retracted height is a little taller than the 9 in Polestar jacks.
Protection is covered by a built-in circuit breaker. Per the listing, it disconnects if amperage runs high and reconnects about 2 minutes later. A hand crank and a weatherproof cover come with it. The listing also mentions a one-year manufacturer service period, which may matter if you want support after purchase.
VerdictA middle-of-the-road 5000 lb jack with useful backups but few published performance numbers.
Best among the reviewed tools
Dynamic capacity is what the jack can lift under power. Compare it with your trailer's loaded tongue weight, and pick a rating above it. Static capacity is a holding figure, and only some makers list it. In this lineup, dynamic ratings run from 3500 lb to 7500 lb.
The jack must fit under your hitch or A-frame when fully closed. Retracted heights here run from 9 in to 9.84 in among the models that list it. Also check max extended height, which runs from 31.5 in to 33.85 in, for tall couplers and uneven ground.
Lift speed tells you how long hitching takes. Only four models list it, with figures from 24 in/min to 30 in/min. Motor power appears for the same four, from 150 W to 250 W. If a maker leaves speed out, you cannot compare it on time.
A circuit breaker protects the jack and your wiring from overload. A manual crank or socket lets you lift when the battery is dead. Also check how it connects. Some listings describe a 7-way plug, and others describe a direct battery connection, so match it to your setup.
Match the dynamic rating to your trailer's loaded tongue weight, and choose a rating above it. The range here is 3500 lb to 7500 lb among the models that list it. Check your trailer's documentation for the tongue weight figure.
Among the six models that list retracted height, 9 in is the lowest. Three share it: the two Polestar jacks and the KYX. The VEVOR HH7500 is tallest at 9.84 in. Measure your clearance before you buy.
Many include a manual option. In this comparison, the VEVOR, KYX, Kohree and Pafessa listings mention a hand crank or crank socket. The Polestar specs do not list one. Check the product page for the tool you need, since some sockets need a separate handle.
A built-in circuit breaker shuts off power if current runs too high, which protects the motor and wiring. Several listings say it resets on its own after a short wait. The VEVOR specs do not list a breaker, and the Pafessa listings mention a 30A rating.
